After watching the disaster at Tokyo, I would say absolutely nothing is wrong with the A350. I can not believe how intact thecA350 was after it came to a stop. The fact that the main landing gear and wings were still intact after running through the Dash 8 is a testament to the aircrafts strength.
meanwhile Boeing can't even secure its door to stay closed during flight and just detach from the frame. i would not trust boeing with my safety at this point.
well it is completely built in carbonfiber composites (just like the 787 dreamliner) Aluminum has a melting point of 660 degrees celsius, composites burn at 400-500 degrees but despite that composite maintains it's structural integrity much longer in a fire than alumium which propably is the main reason that everyone had time to evacuate in time. I doubt everyone would have had time to get off if it was a for example Boeing 777 with aluminum. Unfortunately Boeing made the stupid decision to continue with aluminum fuselage on it's new upcoming 777X to save money on development cost which was another dumb choice, makes the aircraft both heavier and less safe.
@@ragael1024 This is my issue with this channel. It looks very much biased toward Boeing which is understandable if you have a lot of interaction with them. But really, why isn't there any cover of the plug door issue here yet this video on the A350 for something rather minor. It's "just a YT channel" but still, it would still be much more honest to just cover issues for both manufacturers. The MCAS issue was also just lightly touched on this channel with not much blame pointed at Boeing...
@@foadskyflierI'm pretty sure you can't convert an already aluminum fuselage. It's basically Boeing's A330neo. So I wouldn't really call it a "stupid" decision.
I need to make a correction regarding the Trent XWB engines of the Airbus A350. In the video, I say that the A350-1000 has a more powerful engine, which has a larger fan diameter, of 97 inches, whereas the smaller A350-900's engine has a fan diameter of 84 inches. In reality, BOTH variants have the same fan diameter, which is about 118 inches or exactly 3 meters. As some of you have guessed in the comments of the video, this mistake is due to a misunderstanding about the name of the two engine variants: Trent XWB-84 and Trent XWB-97. My team and I were more familiar with Pratt & Whitney engines, many of which have a number at the end, which denotes the fan diameter, and assumed that this is what Rolls-Royce does, to. And you know what happens when one assumes… 😔 In reality, those numbers have to do with the takeoff thrust of the two engines: 84,200 pounds for the -84 variant, and 97,000 pounds for the -97. I really appreciate all of you who pointed this error out as we pride ourselves to always try and bring you the most accurate content possible. Listening to you and your comments often teaches me a lot of and I’m feeling very grateful that I have such an engaged and knowledgeable audience. 💕 //Petter
Hi, A350 pilot here. Some of the info shared in this video are not accurate. The -84 and -97 have absolutely nothing to do with fan diameters, as the two variants have the same fan diameter of 3,0 meters, or 118 inches. Actually you could even say that the -900 and the -1000 are powered by two variants of the same engine, the difference being that the Trent XWB-84 that powers the -900 has a thrust output of around 84000lb, and the Trent XWB-97 that powers the -1000 has a 97000lb thrust output and a slightly larger core (around 5% larger), and runs a bit faster.
Thank you, yes this was a mistake. Pratt & Whitney names its engines by putting a number at the end to denote the fan diameter, but in this case Rolls-Royce obviously uses this number to denote the thrust output in pounds. I’m sorry for the confusion and I’ve issued a statement to correct it.
You need to make sure the information you give out Is accurate, simply sayings its your research teams fault is not on. You are a commercial Pilot and you understand better than most that you don't give out incorrect information or say something that's not true. Instead of producing all these videos, slow down a little and focus on accuracy, it will give your viewers better information and stop yourself looking silly...@@MentourNow
@@david22294Petter did make a correction as soon as it was discovered and he put his hands up straight away which shows his integrity as a pilot. As a pilot myself I find Mentour Pilots content very factual and informative with in depth technical analysis which isn’t watered down for the layman but put across in a specific way which makes it understandable to all viewers. I think we can forgive him for this minor misunderstanding.
Well the accident a Japan showed a very strong airframe, I think this was also one of, if not the most, critical factor that everyone in that plane survived.
The composite fuselage shatters on impact and it releases toxic fumes when burnt. I don’t think it made a big difference if this plane was a 777 instead of a a350 for example. 777 have had many runway fires and had successfully evacuations, such as the emirates crash at Dxb (which had a longer ecvacuation Time, and all passengers still survived)
Oh man, I'm still bummed that the A380 wasn't enough of a success for Airbus. I so rarely sleep on airplanes since I'm over 1m in height and they're apparently designed / laid out for the other group... But once on a Singapore 380 I turned to my wife and said "are we STILL taxiing?" and she said "we've been airborne for 3 hours, you've been asleep for most of that." Damn shame.
@@MrPrajitura You also don't risk shooting yourself a day before testifying or mysteriously getting an infection if you publicly criticise Airbus. Smh disappointed never flying airbus ever again.
If you look back a few years, you find Airbus tails fall off crashing New York City. Airbus claimed the pilot overly used the rudder. My ass. It’s a primary flight control.
Airbus doesn’t need MCAS, they fall out of the sky on their own. Ref: QA A330 flight control computers pitched the aircraft over headed for the Indian ocean, they had stall warning along with over speed at the same time ( same as with AirFrance crash )their EMCAS was lit up like a Christmas tree. This event happened twice in a row. It was only due to the airmanship and skill of the crew that this didn’t end in a total disaster.
All 379 pax successfully evacuated with minimal broken fingernails, evacuated after a 350 (airborne, at landing speeds) impacts a stationary airframe on the deck in Japan - everyone out, with several exit doors blocked, nosewheel absent so front slide too shallow and tail end high. I'd fly on a 350 ANY DAY (but the 380 is still the best IMHO).
To be honest: Whenever I hear a CEO saying "We have to quadruple our profit margins over the next five years," I also hear "The pernickety complaints of engineers and their hairsplitting about safety is an irritation we can't use." Many major industrial accidents are not engineering problems, they are caused by the profit margins being boosted on cut corners." I understand RR needing to compete... but huge airplanes also have huge numbers of people inside.
It's a situation reminiscent of the McDonnell-Douglas DC-10 and its cargo door issue, back in the '70s - best to be cautious when an airplane manufacturer is so singularly focused on profits.
So very true. And even the decision to drop the 350 was purely made from the numbers perspective and by numbers person. Let alone that it's a better plane to fly in 😂
Boeing sold a shed-load of 777-300ERs in the 2010s and most carriers are not yet ready to replace them with new A350-1000 or 777-9. Both frames should see much stronger sales towards the end of this decade and into the 2030s.
That’s is very true, a lot of them are barely even 10-15 years old as most sales were around the early 2010s. And the aircraft performs extremely well. pilots love it. The airplane is still cost effective and super efficient even when put against the a350-1000. Sales will pick up tho in the late 2020s
Also the replacement for 777-300 is 777-8, not 777-9. The -9 is significantly larger and is in essence the boeings proposition as replacement for last 747s and even A380s, and has no direct Airbus competitor ATM. So it's little wonder that Emirates chose the bigger plane. And yes, that means that A350-1000 is directly competeing with 777-8, tot -9. And also Boeing chose not to develop 777-200 replacement in 777X generation, instead they'll probably market 787-10 to airlines replacing 777-200, as both planes are extremely similar in terms of capacity. Now the problem here is that while 787-10 is a better replacement for 777-200, it's not the case with -200ER as it has limited range, leaving -200ER operators a choice of go bigger with 777-8, go smaller with 787-9 or go Airbus with A350-900
@@mancubwwa you’re 100% correct. I also think the -200 market segment is in less demand. As it seems the Airlines just go bigger or smaller I.e. the -300ER and 787-9. I hate the 787-10 btw, I think they should have given it a bigger wing to increase the range and fuel. Bring limited to 12000km in today’s aviation market is just too low for a plane of that size.
@@davidajayi1207 I'm not sure if I agree about 787-10, it seems to be primary directad at US airlines for large volume long haul domestic routes like New York to Los Angeles. With no lie flat Buissness you can fit a lot of people on a really fuel efficent airframe and with overland routes no longer than 5000 km and plenty of diversion airports 12000 km range is more than enough.
Speaking of maintenance costs in dusty environments, I used to make (radio system) service calls to a geological survey camp in central Saudi Arabia back in the early 80s. They had a Bell Jet Ranger based at the camp, but it wasn't available to get me out there, so I would have to dead recon across the desert in order to get there in my Nissan Patrol SUV. I talked to the pilot once lamenting that he couldn't fly me in, and he told me that they would only get 12 hours out of each tail rotor due to the dust, and they cost $26K each!
MentourNow is a very Boeingcentric. I think Airbus is doing just fine. And the Boeing build quality again coming into focus with the Air Alaska 737 900Max fuselage damage. One problem after another
It's kind of expected that he has sympathy with the same machinery he's operating, ...but despite being a 737 pilot he showed on several videos that he's well aware of how far ahead Airbus and even Boeing tech are compared to the 737 series.
Yes. A350 is excellent. I often fly SFO-Singapore but also flew Singapore-Christchurch recently, all on A350s. But still my favorite aircraft is still the 747-8. But that’s tough to find unless you are flying Korean or Lufthansa.
I believe there's nothing wrong with the A350, never have I seen and travelled in such a well build, safe- and comfortable plane. And like others have mentioned, look at what happened in Japan.
@@sn4tx Exactly, but this thing that's happened to the 737 MAX seems to be a company wide quality issue so I have to wonder if it's going affect 777 as well in some shape or form.
@@mutkaluikkunen3926 I’m not a Boeing fanboy nor an Airbus fanboy. Do Boeings crash? Yeah so do Airbus. But you are right. As much as I’d like to just keep these uneasy feelings I have towards the MAX (granted I’ll never step inside one of those), with all the issues plaguing other programs one does have to start considering. And hey I’m not driven by paranoia. In the 737 defence, Iots of them been flying by tons of airlines all over the world. So statistically one could say, the 737 MAX isn’t that much of a dangerous plane. Same thing happens in the car industry. Now the issue here is if a certain car model of a specific brand has a chronic quality issue that makes them break down more than the others, at most you gonna be walking or taking a taxi. If a plane breaks Down … yeah they not gonna park in some random cloud till assistance comes. And as a whole it’s true that Boeing been having some problems across the bussiness. Some more serious than others but still. It shots the reputation and mostly the trust people have on the brand. So yes. Of course as a passenger that likes to check what plane I’ll be flying when I book flights, I’ll be actively avoiding Boeing in general. Doesn’t mean I’ll be 100% safe. But surely being 90% safe beats being 60% safe. Now it doesn’t mean I won’t get on a Boeing plane, if that’s my only choice for the route and time I need. BUT even if air travel is, statistically, the safest way to travel I still prefer to take my chances on a car crash than on a plane crash. And one way to improve those chances is to stay away from those crazy nonsense MAX program planes. That shit should be banned straight away from everywhere. I mean yesterday was MCAS, today are plugs that go “Aight, I’m outta here”. Heck I not gonna be in a future flight that has the potential to show yet another issue with the MAX.
We must also not forget, Emirates have a large fleet of 777-300ER's and 777Fs, bying the new 777X will keep crew familiarisation and maintenance as they all use the core GE 90 engine which yes it's new family on the 777X but still GE, flight crews inc cabin and cockpit crew will be familiar and trained on the current 777 so transitioning to the new one will cost less. It just makes more sense for Emirates to go this route. Also the only aircraft within the size of the A380 is the 777-9.
You can say the same about commonality for the Airbus family of planes. There is even more commonality for air crews than Boeing will ever achieve within the 777 line of products, old and future once. The statement about the engine is even more surprising after GE had to redesign every section of the GE9X during the 777X testing. The GE9X is the main reason for the delay of the 777X program. Assuming the hot and sandy environment would have no impact on the GE9X is wishful thinking. On contrary, the large 777X contract might bite Boeing and GE big time. There must have been HUGE incentives for Emirates to place such a large order for an unproven, not certified wide body airliner with new, unproven engines. The incentives are a close held secret, but it must be way more than a simple discount. A discount can't cover Emirates risk of having to ground its 777X should there be teething issues like experienced with the 787, or if engine issues surface with the GE9X. The contract must have some writing in it, that is covering Emirates risk, and that again might lead to huge losses for Boeing and GE should their products not perform as specified in the contract!!!!!
Would agree totally, if Boeing aircraft today, were built to the same standard as Boeing of old. To me the 777x is likely another MAX- Its still the same management.
Just a minor point about the 787. It actually does have bleed air but only for the inlet lip. All other systems that traditionally used bleed air are now electric. I have a friend who is currently in 787 transition training and he was as surprised as I was. And I actually work on the 787 for a living!
Wasn't the bleed air port a modification to solve icing conditions on the inlet lip of the nacel? That modification was made years ago. I had smile when I saw the comments of the bleed air less engine suddenly getting a bleed air port added to it.
@@aquaden8344 On the RR engine it uses HP3 air (if I recall) for cowling anti-ice by a dedicated PRSOV. Air-conditioning air is supplied from the CACs (Cabin Air Compressors) to the air-conditioning packs. Wing Anti-ice is electrical heater elements in the leading edge slats. (WIPS).
Hi MentourNow Team, great video! 10:34 I’d like to clarify some misconceptions on the Trent XWB-84 and -97. Online sources indicate that their fan diameters are the same at 118 inches. The increased thrust output of the -97 comes from different internal component designs such as the larger core. Articles also shared that the increased power results in higher temperatures and requires improved cooling. Perhaps the high ambient temperatures in the Middle East also cause lower than expected time on wing performance because of these rotables and life limited parts being affected too. Thanks for the video it really got me searching and learning more! Cheers!
Thank you for the information! Yes the fan diameter is the same, this was a mistake, it was the internal differences that were large enough for the two engines to end up with different designations.
Hmmm i am not sure about your take on temperatures. Jet engines operate under high temperatures, we, are talking about hundreds of degrees. How much hotter does it get in the desert? maybe 20 degrees or 30F. Thats a big difference for you and I , but not for a machine doing say, 800-900 degrees F? Plus, a lot of their hgih density departures happen at PM, when its MUCH cooler. My point? There must be something else to the story...
Combustor exit temperatures are well into the >1900K (~1600-1700C) for modern turbofans, well above the melting temperatures of the nickel alloys that the turbine blades are casted from. They require highly elaborate barrier coatings and actively cooled by enveloping the blade in a film of cooling air (which by the way, is already well above 600C to start with). A hot & high takeoff at say ISA+20C could have a significant impact on life-limited parts compared to the nominal flight profiles, so inlet temperature matter much more than you're making it out to be. When your components area already running at the very edge of what's physically possible, an extra 20 degrees matter a huge amount.
Very well laid out. We've seen some additional blows to the A350-1000 as of late. The Turkish mega order involved 1000s, Delta is supposedly in limbo for twenty 1000s, Air India reshaped their A350-1000 order from 34 to twenty aircraft and Cathay converted their last five 1000s to 900s a few years back. Rolls and Airbus really need to iron out the issues, especially while the 777X is still in certification limbo. The A350-1000 did win some orders (Air France, EVA Air) but it should be a runaway success because of its availability.
My son has flown to Australia and back from the UK three times in the last fifteen months. He's flown on 777s, A350s, a 787, an A380 and 737-MAX (Singapore to Cairns). His favourite plane by far of all those is the A350 as used by Singapore Airlines. Apart from the 737-MAX which he found very cramped, the one he disliked the most was a 777 operated by Swissair, which he said was very tired and poorly equipped compared to the others.
Thanks for this comment..your son has good judgement about aircraft and I agree that the Airbus 350 (Singapore Airlines) is probably the most comfortable long haul..Have taken it many times from Christchurch-Singapore. and Singapore-Auckland.
I flown flydubai 737 MAX 8 and no thanks... cramped, old hull. Maybe good in terms of training, fuel efficiency but its an old style aircraft. I also hated the infotainment. Extremely big and bright screens and as it is so cramped, many will touch your screen by corner when passing by and turning it ON for you when you are asleep. Shitty design.

Hello, I just flew an Airbus 350 4 days ago from TNR to CDG (11h flight time). It is by far the quietest and most comfortable plane of its category.
To be honest, Emirate's concerns are valid. An engine that can't handle a little sand is an engine that is already picky about how you operate it. These might be finely tuned machines, but they have to be quite tolerant of abuse all the same. And if it's "fine in benign conditions" then that means it's fine year round... exactly nowhere in the world. Rain is not a benign condition, neither is snow sleet hail or sand. And I don't think humans have a large habit of living far away from any of those things. In fact, I doubt you can find a place on Earth where none of those things happen some time during the year. It's like saying "This WiFi adapter has a 10 mile range.... under ideal conditions". But then stating that in realistic conditions it has a range of maybe 50 feet. Granted, 50 feet might be enough for most people, but they're going to price that adapter based on the 10 mile figure ($$$$$), not the 50 feet figure, because you can get adapters that get better than 50 feet of range in realistic conditions for about $20 shipped to your door. Point is, everyone that matters to this discussion knows that "ideal conditions" don't exist in the real world. So to claim that your engine "works fine in benign conditions" when you are talking about an aircraft that needs to operate in ALL weather conditions, even the bad ones, is quite telling that you still have quite a bit of work left to do on your engines. The real world is INCREDIBLY MESSY in pretty much any way you can think of.
Hello Mentor, I just want to clarify that for the XWB-84 engines on the A359, the 84 denotes its thrust rating of 84,200 lbfs and on the A35k which uses the XWB-97, the 97 denotes its thrust rating of 97,000 lbfs, both XWB variants have the same fan diameter of 3m or 118 inches.
I notice a huge difference in how my body copes with a flight on a 787 vs A350. The airbus always gives me a nasty headache, whereas the 787 leaves me feeling fine :)
@@jgldev It's quieter, smoother, less prone to turbulence (advanced 'gust suppression' technology) and it's pressurized to an equivalent of 6000 ft altitude (most others are 8000 ft). All round Delta economy was quite comfortale and didn't leave me feeling tired (after 14 hrs) like other aircrafts would. 787 is pretty nice too but I place the 350 above the 787 for quietness and comfort.
Hot and dusty conditions are hard on any kind of combustion engine. I can imagine it's even worse with turbofans that are sucking in enormous volumes of unfiltered air every single flight. Parts made of rubber and plastic deteriorate faster, and lubrication oil will break down sooner in these higher temps. I can understand that Rolls Royce is trying to play it safe with these more frequent off-wing maintenance intervals.
@@oadkathey are about the same, it depends on where you sit. Both planes are extremely similar in terms of types of technology used. The a350 s engines are about a half a generation ahead tho. Cabin pressure is the same for both 6000 feet.
I just don’t think people remember that the 350 is a decently larger airplane than the 787. They’re not really interchangeable. 787 can be better suited for small markets / different business models
According to the TCDS the fan diameter is the same at 118". The designation comes from the thrust output. Did you not think it was ironic the fan diameter and thrust output were both the same?
I buy flight tickets now with 35 years of travel under my belt based on the aircraft type... No to 320’s , yes to 350’s and 787’s.... but the best ever for me was upstairs business class seating on the old 747-300 SP’s.... maybe a touch of nostalgia in that comments but very fond memories of that plane
Translated as: "Boeing offered an entire fleet of 777x basically at production cost." Same thing as Hawaiian Airlines' 787's last year. Tim Clark MUST understand how ridiculous it sounds to complain about aircraft out of service then buy a bunch of Boeing jets.
It seems to be the fact that the A350's advanced composite materials and insulation played a part in the "Miracle of Haneda" evacuation that 369 people survived from the crush and fire. Ironically, Airbus has no choice but using this seemingly responsibility-less incident to push their business forward, and I cannot complain as a Tokyoite. Meanwhile, let me pray for the 5 perished Japan Cost Guard personnel in the accident who were on a rescue supply mission for the Reiwa 6 Noto Peninsula Earthquake disaster.
Surely composites don’t have much of an impact. I imagine that the burning composite releases more fumes when burnt, and it shatters upon impact rather than aluminium, which would dent. So I don’t think there would be a major difference if instead of a 350, it was a 777
@@centauri1962 You could say so, but with all due respect, I’m not so sure. About the strength, even as stupid as he could be, the Titan’s owner didn’t dare to make his submersible by aluminum with the same material weight as his carbon fibre. And fumes? One big aim of developing and using such composite materials for the fuselage is flame retardancy to protect passengers inside. The materials of the walls and insulation were carefully designed and layered to serve that purpose. Evidently this time, they succeed in that to some extent, since there were no casualties out of respiratory tract burns and the fuselage structure didn’t give in long after the evacuation finished. The calculated impact and heat resistance of the materials used in the latest airliners like A350 and B787 are slightly but surely better than their predecessors except for such materials’ characteristic unseen time deterioration vulnerabilities.
Cheers and thank you so much for not just covering airplane incidents and piloting insights but also industry usage, needs, overview, and ternds. I appreciate the insight into this industry you provide that outsiders like me greatly appreciate experiencing.
All of the times I have traveled on a 777 was on board of Air Canada, operated by Lufthansa in the early 2010's. Even back then I was quite surprised that these were 6 flights all with Rolls-Royce engines, for me it just didn't make sense for some completely superficial reasons like "American jet with a British engine, when there are other options". I don't believe that Emirates had issues with the RR engines, something else must've gone wrong between them and Airbus, given that as of December 2023 the best economy comfort that you can get is on an A350-1000 and Emirates usually go for it.
Captivating analysis, full of detailed product comparisons and understanding of each market player's motivations. We began watching with the intention of merely "sampling" the episode, but ended up watching it twice.
The a350-1000 is still doing well. I’m sure Rolls Royce will work on increasing the time on wing performance and I have a feeling Emirates may order this aircraft at some point. Emirates even said they love the aircraft, as long as this issue is fixed it will definitely be considered at Emirates.
I can imagine if the 777X has further delays and if there are problems in the beginning, Emirates will start to shift to the 350. Or airbus just starts with the A380-900 😅
@@byFoxiI doubt Airbus will ever build any more of A380 variations. The project costs Airbus over 20 Billion of Dollars and clearly Airbus is not able to turn a profit from the program. They plane maker has put down all of the quad-jet’s production line which makes the restarting of the aircaft is as expensive as starting a new project. Even though there are airlines other then Emerates want a NEO version the A380, I do not think it will be sufficient enough for Airbus to just simply consider it.
There is no way Airbus starts the A380 again. No facility is opted foir that by now, so its just a completly new production line. The A380 was nearly at break even but a lot of prestige was gained in building it that is way more valuable@@thevinhnguyen1661
I thought it was worth commenting on the jet engines operating in hot, sandy climates putting more stress on the engines. A fair number of airlines operating in warmer climates operating the A220 have had to ground their aircraft because of reliability issues with the P&W 1000 series engines. I believe Pratt & Whitney have just now been able rectify these issues ?
As a load planner, the trimming is a problem when flying with full load , many-times I do need to offload cargo due weight and trim, so the fwd hold is empty in long haul flight😂 so I don’t know how the a350f will operate with that trimming. But the a350 family do more fuel economy than others
Mentour, actually pretty good analysis, also it is wort to add: CEO of Aribus resigned during A380 as he said: " as I can not guarantee required reliability of the aircraft we forced to make". Now, when A-380 way earlier stop production, with cost of maintenance over 10000 pounds after each landing, this story its correct, again.
Very good video!! I work as an inspector in the Trent family LPT turbines (IPT in the Ultrafan) manufactured and assembled here in Spain. The 84 and 97 variants refer to the thrust the engine provides (84K and 97K pounds of thrust) . Like all your videos!!
Thanks for the info! Yes this was a mistake. A small confusion between the way R-R and P & W name their engines..! I've issued a statement to correct it.
First of all this is a fantastic series (as well as the accident series ) and Peter and his crew are to be given mojo credit for a fine productions, the best in their categories hands down. That said, the Trent 7000 is much more like the mentioned difference between the two A350 XWB variants. The Trent 7000 is descended from the Trent 10 (1000 TEN I believe is its moniker) and the TEN is a 75% new engine over the Trent 1000. Once parts counts approach 50% its considered new (disagreement on that, varies from 40 to 60% in various views). Regardless the TEN should be counted as new and the 7000 has a very detached relationship in the 1000 engines. The 1000 itself is no longer made, replaced by the TEN (doing nothing for its attraction on the 787 that the Trent 1000 was never all that well regarded and more so with the failures). Two major RR users (NZ and ANA) have dropped it and are buying the GenX for the 787s they buy now.
As an engine mechanic for 26 years at Boeing Everett, I was always proud to wear my Boeing t-shirts, polo-shirts, hats, etc. out to everywhere I went, NOW I am ashamed and scared to...and it is not even Boeing fault. I blame McDonnell-Douglas, they took one of the finest engineered airline producer in the world and totally turned it into fucking shit!!!
Great video! One question I have for Emirates - the Rolls Royce XWB might be performing poorly now, but what makes them so confident that the GE9X won't have problems of its own? Being a brand new type I suppose it makes sense for large airlines to order a mix of Boeing and Airbus jets to have some resilience against reliability problems for a given type, but that entails slightly higher maintenance and crew training costs compared to a single type
The slick salesmen often say things that engineers would disagree with, however in this case I think the XWB did have some new technology which seems like it may come at a cost.
Hmmmm let's see, the Trent XWB has a dispatch reliability rate of just 99.91% and the GE90-115B/GEnx have a dispatch reliability rate of at least 99.98%, and with all this experience and proven track record GE has, we can see where this is going
@@gertjanvandermeij4265 In case you haven't noticed, for all the main reasons, efficiency, safety, economics, fly-by-wire is the "future" of commercial aviation since the late 80s'!
The reason the A350 does not have a GE engine was because GE did not want to canablize their GE-90 sales with a new engine for the A350. And before GE had a "Gentlemans" agreement with Boeing.
But the question is, when Airbus decides on doing an A350neo maybe in the early 2030s, do you think they'll stick to just RR or will P&W also enter in with their GTF engine but designed specifically for widebody aircraft?
@@CoSmicGoesRacing RR has their own GTF project, UltraFan and Airbus should have be working with them for a while, and chances are the first application would be A350NEO.
@@CoSmicGoesRacing Airbus is a burnt child with PW(A340 GTF/ A220,A320 engine issues). I'm sure they would prefer GE. But without GE they stll may go with PW.
I can't help thinking that Emirates are just playing hardball with Airbus and RR. By withholding an expected order and making the 'defective' comments, they will eventually end up with a more satisfactory engine on-wing service interval and probably better commercial terms than if they placed the order sooner, with conditions for serviceability to be improved in due course. Given the long lead times for the airliners, delaying a year or so before placing the firm orders really piles the pressure on AB and RR at little risk to Emirates. In fact, once they do decide to place orders, they can probably use their purchasing clout to jump the line for delivery slots.
@@rafaelwilks Among the latest gen engines though TrentXWB is arguably the most reliable in widebody sector. Even GENx suffered from midflight shutdown and grounding due to icing issues. TrentXWB has none. But none of the engines are as reliable the more last gen ones, both as a result of less mature and pushing closer to physical limits to achieve efficiency.
@@rafaelwilks That was not caused by design defects, and no subsequent grounding was resulted. Al Bakar at some point threated Qatar would not receive any more GENx-powered 787 before the issue is fixed. He did mooed about Trent XWB but never took a fight against RR up to this date.
That's something I questioned as well . Rolls Royce being the sole engine supplier for the A350 sems crazy their sakes could be bigger if they could fit another engine from.a different manufacturer.
Well, considering that Air France - KLM (the latter in particular) are switching from Boeing to the Airbus A350, including the 1000 model, I’d say that that airplane is still doing pretty well.
@@Jebbis, why would an airline operate B744 if they have B77W, which is about the same capacity and range? For Lufthansa due to airline’s size it is slightly more problematic to get quads out of the service.
@@interstellaraviator6437 Lufthansa wanted to replace their still large A 340-Fleet with 787 Dreamliners (at Lufthansa itself and their two subsidiaries Swiss and Edelweiss in Switzerland) years ago but don´t get deliveries from Boeing until today. So they bought now five used 787 from Hainan Airlines in China to simply start their 787-Program - but their A 340 have to persevere, allthough especially their A 340-300 are really aged aircrafts now (Lufthansa: 17 A 340-300 and 10 A 340-600, Swiss 4 A 340-300 and Edelweiss 5 A 340-300). The Lufthansa Group has only six 777-200 (and still three 767-300) at Austrian Airlines, which shall be replaced by ten 787-9, for which Lufthansa is still waiting. Otherwise Lufthansa uses the 777 only in its Freighter Version at Lufthansa Cargo (operating now a fleet of eleven of them and with seven 777-8 Freighter on order). Lufthansa has a fleet of eight now also aged 747-400 in the Passenger Version (becoming therefore one of the few remaining operators of them) and also a fleet of eight A 380. Both they shall be replaced by ten A 350-1000 and all-in-all 53 A 350-900, from which 21 are delivered and the remaining 32 will be delivered during the next years (the A 350-900 Order includes Orders for Swiss and Edelweiss in Switzerland, too). The 19 747-8 are only round about then years old and shall be operating for the next ten to fifteen years. That´s about Lufthansa Quads.
@@Trancial-x-tion They have been partners for a long time, during which when they placed orders with both Airbus and Boeing, the Airbuses usually went to Air France, and the Boeings to KLM. That has now changed.
Well Cathay recently ordered 6 a350F + 20 options moving away from their all Boeing cargo fleet. Any Emirates show-stoppers are more due to economics rather than engineering. They just didn't get the discounts they wanted.
If a competition is giving a better engine for a lower price why wouldn't they take it? Even Thai has ditched A350 for their upcoming huge order due to RR engine prices despite being a historically loyal RR customer.
Yes it's very different and yet by all accounts, Emirates was on the verge of taking the a350K. Did they discover that they operate in a hot and dusty environment in the few hours before the show?
@@aseem7w9 If Thai is giving up those A350 they just acquired they're ditching A350. And no they were not loyal to RR - quite the opposite. They were known for a messy fleet, ordering almost every aircraft type with engine from all 3 manufacturers. Also IIRC RR at some point bribed Thai management for orders, so there were some troubled histories as well.
@steinwaldmadchen They aren't ditching the 350 but ditching it for this specific order. Thai having messy engine choices must be a long time back because in recent history whenever there was RR they chose it, 330 340 772 773 787 you name it, and they probably weren't bribed for every single one of these. GE came for 77W where there was no RR option
The fan diameter of the RR XWB-84 and XWB-97 is the same. They are both at 3 m diameter, the number is related to the max thrust of the engine (84k lbf vs 97k lbf).
Thanks for the video. A very good presentation of the background story regarding engines used in Wide Bodies and the economic and strategic orientation of the engine manufacturers and operators. What I don't understand, however, is the lurid title of the video. Why lose reputation for more clicks? realy? 🤔
I was thinking of the issues Lockheed had with RR when they made the Tristar. That was a great plane but the delay in the power plant killed the sales.
Rolls Royce has also stated that they’re focusing on seriously maximizing profits in the upcoming decade. That means very few discounts on engines. The A350 only having the one option for engines, that means engine costs are way higher too. This is part of the reason Delta Air Lines hasn’t ordered the A350-1000 yet despite it fitting well in their structure after they retired the 777 in 2020.
It's clear Airbus made a big strategic mistake to only have 1 engine provider. They should have spent a little bit more for a 2nd option, and would likely have won the bid
@@Matt-YT Sales of the A350 do not indicate a "big mistake to only have 1 engine provider". Its pretty likely that the 350 will be one of the world's most successful widebodies of all time, without GE. The mistake was that GE didn't push hard enough to get involved in the first place, although Airbus now sees GE as primarily the engine partner for Boeing, and not with themselves. Its GE that will be desperate to get involved with the A350, once RR's exclusive expires, as they look on enviously at RR's success, but I suspect Airbus will stick with RR, as Im sure RR will be transferring tech from the Ultra Fan to engine what will be coming next, the A350 Neo. Sooner or later, American operators will go with the rest of the world regarding w/bodies, and buy a wholly European aircraft, airframe and engines, without worrying about the politics of buying foreign. Delta can either pay RR what they're asking for such a competitive engine as the XWB, or spend more buying GE engined B787s, with all the extra costs that entails for them. The choice is theirs and either way will not have serious consequencies for the A350.....
Increasing time on wing is the key to RR profitability improvement. RR's Power by the hour charging means RR picks up the cost of reduced service intervals. So RRs profit improvement plan will likely make the A350-1000 more attractive to Emirates.
Couldn’t Rolls Royce have a number of serviced engines for a hot swap. The delay then would just be the time to take off one engine and bolt on another.😊
I'm guessing they're not committed to promise a ready engine to hot swap, either with high number of airframes waiting for new engines to be installed, or they don't have a high turnaround for new or serviced engine ready
The A350 has been picking up orders very successfully this year including the larger 1000. I wouldn’t expect to see many orders in the n😢ten weeks but at the forthcoming Farnborough show it could be quite interesting to see if Rolls and Emirates have closed the gap but there are also many other order possibilities both new and follow on including BA who are now operating 18 and had options for a further 18! With production set to ramp to rate 12 there should be spare capacity available to satisfy Farnborough demand, interesting times!
The biggest problem is the artificial fuel shortages. Globally we are doing everything in our power to suppress free market oil production and these aircraft suffer for it. Then there's ETOPS. As there's no more tri-jet models in production, we are forced to make bigger twin jets. The 777x and A350 are perfect examples of that. The Quad jets are being phased out and only the rich Asian airlines are keeping them.
Thanks for your objective and comprehensive presentation. Rolls-Royce is not a favored supplier with airline executives. High overhaul costs and slow shop turn around times add significantly to the total cost of ownership. Boeing and Airbus have both gone to single source engine suppliers for their B777X and A350-1000 aircraft, which keeps certification costs lower for the airframe manufacturers but removes engine supplier competition from airline procurement.
With the development cost of a large jet engine, few companies are willing to outlay 3-5 billion dollars on a engine that only starts to repay development cost 5-7 years down the road, when orders get split at 50/50. Look no further than the A380, when General Electric and Pratt&Whitney no bid an engine. It wasn't until Airbus plead with them to team did the Engine Alliance form, and received cost to 60% of the orders. Airbus love exclusive engine contracts. They get cheaper prices. The customer on the other-hand might be a GE or Pratt operator and shy away from Rolls due to past issues.
@@ant2312 I happen to be an Airbus fan, though not fanboi. Worked flight test for the A320, A300 and A330. Airlines invest million in tooling to work on their own engines, so they're invested in an engine type. As for Rolls, their inferior product caused Lockheed out of the commercial aircraft market with the engine for the L-1011. The Trent for the 787 grounded many 787's for over a year. Boeing had their own 787 issues with batteries, but Rolls hasn't been stellar in their large engine market. I will give them credit for the IAE V2500. The absolutely quietest turbo fan engine I ever worked around.
I bet Emirates was upset with Airbus because AB would not build the A380neo. I think that is the real reason Emirates gave the huge order to Boeing despite the delay with the 777x.
As someone who flies internationally often I'm so disappointed to see the 787 and A350 not being the only aircraft sold at this point. The comfort of flying on a composite airframe with a much better pressure level is unbeatable. I flew to Bangkok last time on an A350 and then back out on a 777 and the A350 was incredibly more comfotable to be on for a long flight.
I haven't flown on the A350 yet but I couldn't disagree more on the 787. Airlines are encouraged into such a dense Y configuration that there is less than no width at shoulder level. For sure the whole "dreamliner" moniker was a stroke of marketing genius but the aircraft itself is simply awful. I swear people say they like it because they feel they should say so. I'd take a 777 over it any day
@@infidellic Me too. 777 TPac BKK>LAX is just fine, although A380 was head and shoulders, but it's not a fair comparison. Only did 3 hour hops on the A350 into and out of BKK, not very long, but nothing stood out to me as exceptional, other than it was a brand new aircraft at the time.
The Brits are no GAGA-Yankees, I think this shoot will miss his target. But there are many things that I thought of the Brits, before there Harakiri called BREXSHIT.
Whatever might be wrong with Airbus, their "toy" planes have not been recorded diving to the ground or loosing significant body parts in flight recently. Which is helluva more than can be said of "oldschool mechanically controllable" Boeings. By the old logic of "the workshop where a big mishap recently and loudly is likely the most polished for awhile afterwards" I fully expected the MAX disaster to cause a good deal of right changes over there. Oh was I wrong.
@@JK-dv3qe I think the "recent mishap means all is polished now" effect not working at Boeing is horrifying. It means that as present, leadership, staff, capabilities, - even existential threat problem - which MCAS scandal was - does not cause'em to put their shit well together, and make sure at least for awhile, dust settling, everything Boeing is top-notch. This is the sign of rot so deep and integral that combined forces of genuine conscience ("we released planes with system that killed 350 people and we need to strive to make up for it") and simple corporate business care ("making planes that crash on their own is not a good prospect neither with regulator nor with customers") are still WEAKER than the fuk-all inertia.
@MentourNow do you believe that the engine is the problem here? What would have happened to Boeing, if after Paris, Airbus was going to get more orders in Dubai also? Would Americans allow such a thing? Do you think politics has nothing to do with it?
I was a design engineer for a component on the RR Trent XWB engine, I understood every word of this discussion. I know exactly what you are talking about. I know the difficulties of working through issues is immense, you explained it very well. I know engineers in Derby, where the RR XWB is built and tested. They are very thorough engineers, but there are a thousand pieces to the puzzle that neee to fit to make it work.
I was looking at the sales figures and they are not so bad. 😊The problem for airlines is to chose an old type with boeing or the future with Airbus. It seems that the ones choosing Boeing have an advantage for the next 2-years and a disadvantage for the following 10-15 years. The CEO of Emirates should think about it because he is facing already the competition with Qatar and Etihad. On top of that, Boeing is for me the airplanes to avoid after the disastrous cheating on the 737 Max.
I flew first class on A350 with Delta today. Really bad weather, heavy rain, foggy, and windy, but the A350 cut through the weather like they don't exist. Idk how it compared to 777, but it's super stable, and the cabin pressure and air quality is good (barely notice a change).
You know what confuses me, the A330 Neo, in theory it should but performing way better, but it's sales are really slow. Even though the A330 Ceo is a popular aircraft. Why aren't airlines phasing out the older 330s?
Just as an example, my country’s flag carrier is Iberia, and it’s A330 average age is less than 8 years, being the oldest -200 about 5 years old. This is the case for many airlines, therefore absolutely no need to replace their CEO A330. I assume this is the case of many other airlines in which the A330 plays and important role on their fleets.
They will phase them out eventually. Airbus did the A330neo mostly because a modest upgrade to the A330ceo would be economically competitive with the 787 (there’s even not that much weight difference). They use it to bid against Boeing in competitions, limiting the profit Boeing are making on 787 sales. Dollars not earned by Boeing makes it more difficult for Boeing to claw back the huge amount of market share ceded to Airbus over the past decades. Plus it’s there for when all the A330ceo operators do start needing replacements.
Mmmm... some years ago I was flying in a 787-9 of JAL from FRA to NRT (eco class) and it was by far the most comfy flight of my life. And I am 6ft tall! Enough leg space, comfy seats and cabin noise from the engines was neglectable. Ok.. I never was flying the A350 before. But 787-9 and A350-900 are very similar.
Orders are one thing, but deliveries are another. Both manufacturers are well behind in fulfilling their current orders, so I don’t think either one is suffering.
@@MentourNow Well one of the manufacturers has to compensate their customers due to a LOT of downtime due to not having their own shit together. And that's Boeing. Not to mention more and more people just don't trust the latest 737 planes anymore. Which is a shame given that the 2nd and 3rd generation 737's build up an amazing record which is now in shambles.
Both 787 and A350 are hi tech aircraft. Technical problems and difficulties are to be expected. 777x is a safer bet and with the demise of the 747 and the A380 the 777 is the best large two engine aircraft out there. For Emirates being a large 777 customer already is way easier to continue with the type. It has a better engine too.
The A350-1000 seems to be cheaper & more efficient. Maybe Boeing offered a huge discount - combined with a small advantage in capacity and cargo. Both planes are beautiful. Qatar 350X lands here at DFW and its very graceful.
@@Chopper153 Hmm, yeah actually the 380 is probably the quietest now that you mention it, followed closely by the 350. Then maybe 787, which I didn’t find amazingly quiet.
The A350 series is a clean sheet design with a high percentage of composites and has a much lighter airframe than the Boeing 777. The 777X has yet to enter service and Emirates are taking a lot on faith that it will not have issues and that the GEnX engines offer better operational service than the Trent XWB. If GE fall short then there will be a lot of red faces at Emirates.
Considering that the Trent XWB has a reliability rate of just 99.91%, and the GE90-115B/GEnx have a reliability rate of 99.98%, we can see where this is going
"Much lighter airframe" - Not really, while it will obviously depend a lot on PAX config, using published OEWs of 352k with 369 PAX in 2 class config for for the A351K and 400k with 426 pax in 2 class config for the B779, you arrive at a slightly lower weight of 938 lbs OEW / PAX for the B779, and 954 lbs OEW / PAX for the A351K. So if anything, the 777-9 is actually a lighter airframe for the number of passengers it carries. I would speculate this is down the the 777 aluminum fuselage being an extremely advanced design, coupled with Boeing's 2nd gen of composite wings, while the A350 is Airbus' first generation of composite wings and a nominally composite fuselage that seems to be optimized for ease of manufacture rather than outright weight savings (panelized design with metal frames instead of full barrel monolith).
@@TeKnOShEeP 160t for 35K is way off. Nominal published OEW is 155t, actual OEW seen from various airlines are slightly lower, while with NPS it is 1.2t lighter than ever. As for reference, 359 and 78J has around the same OEW before NPS, with 359 having a larger wing, higher MTOW but slightly shorter fuselage. 777X in comparison is heavy. 181t is a very optimistic estimation for the 779, while 778 is simply uncompetitive against similar sized 35K. Even as an aluminium frame, 777 isn't exactly known for being light either - 333 is 7t lighter than 772A, and 10t lighter than 772ER. Even the quadjet 343 weighs less. The true strength of 777 though is its heavylifting potential, which helps them avoid direct competition from below. Regarding wing, it's more like a tradeoff than Airbus "dumb". Boeing's approach means a lighter wing, at a cost of higher wing loading and flexing (which increases drag). Airbus' look stiff, but in return it has low wing loading. 350's wing are strong at climb and field performance. A330/A340 wing was also very good, considering it managed to keep A340's fuel burn not too horrible even with 4 shortaul focused CFM56s, or A330NEO closely match 787's fuel burn with no major changes other than winglet tweaks.
@@steinwaldmadchen Er, what now? I've weighed more than one A351 at several MROs, and none of them were lighter and 345k, most in the 350k range. No idea who is operating them lighter than that, unless it's an all economy config or something. Also, lol, no 787 is within 10k of an A359, even the heaviest -10. The 359 is a much bigger plane, that's why it carries more PAX and has a longer range. 777X is still in development, so not sure how you can say it's heavy when no one has been able to weigh one in service. It has a completely newly designed fuselage, with updated gages and alloys, so I don't really think the classic design from 35 years ago is really a valid comparison. I would expect weight savings on par with what happened on the A320 classic-> NEO, as it's a similar timeline. Aluminum design has quietly gotten very, very good while everyone was jumping on the composite bandwagon. If the released numbers are at all accurate, then it will in fact be a very light airframe, contrary to your assertion. Wings? Flexy != draggy with any halfway decent understanding of elasticity by the designers. But form drag is a thing, and A350 wings are thiccccc, especially that wing root, mmm damn. The 787 is known to be an extremely slippery airplane that is very easy to inadvertently hit Vmo in cruise, the a350 not so much. TO/Climb performance depends on a lot of factors, but yes, lower wing loading does improve it, so it wouldn't surprise me if the A350 does have a higher max climb rate (don't have the ops manuals in front of me so I can't confirm that). In cruise though, no, you're going to pay the price for that form, and also the extra skin drag. There's a reason glider wings are the way they are- low drag. And again, we return to the A350 wing physically having more material in it- shouldn't be surprising it's draggier- it's bigger. Fuel burn is a wonderful topic that can be argued until the cows come home, but at max range the per passenger mile fuel economy of the 787 and A350 are very similar 19.5-20.5-ish NMi/lb, the A330Neo is a tad behind at 18-19ish. All of that is way, way better than the poor A340 which, sorry, was in fact horrible, 14-15ish NMi/lb. No magical wing design (which it didn't have) is getting around the fact that quad jets inherently burn more fuel than twins, for obvious reasons.
@@TeKnOShEeP You seemed to also mix up things 1. A340 is a 90s design, of course it can't compete with modern designs like 787 and A350. And it is not great when comparing with A330 of same size, its sister twinjet. However it actually burns slightly less per trip than similar sized 772. And the trick is a lightweight frame and good wing, combined with some other compromises. 2. A thick and stiff wing doesn't mean it's bad lol. And that is reflected by A350's high lift / drag ratio. A350's wings are efficient lift generators, and L/D ratio is in fact better better than 787s. A larger wing area also result in lower wing loading, allowing the aircraft to climb to higher alititude earler for more efficient cruise, and lower thrust for takeoff (while 77W and A321NEO is the opposite). TrentXWB-97 actually has 10klb less thrust than Trent 898 that powers 773, despite 35K's higher MTOW. The wing is approprate for a heavylifter with long range flying in mind. 3. A330s are also surprisingly competitive at that front as well, in fact LD ratio also slightly higher than 789/78J, hence why Airbus kept the wing largely untouched when developing NEO. (They aimed ~2% behind 787, at least for 339 vs 789). As an older metal wings there are more compromises on the 330 side, and cruise speed is one of them. But that's not the point - the wing was extended significantly after the initial SuperFan for A340 was replaced with CFM56-5C, to compensate the worsening TSFC. 4. The wing flex of 787 does mean lower L/D ratio by reducing the upward lift generated. It's not desirable, but it's also a result of tradeoff. In fact 787's wings were more optimised for -8, they decided not to make bigger wings for -9 and -10, for the sake of production cost and weight savings. 5. According to ACAP published by Airbus, the highest MZFW found on 35K is 223t, while structural payload is at max 68t, which translates into an OEW of 155t. And according to pilots working for Cathay Pacific (a heavy user of both 77W and 350), their 35K consistently load better than 77W, while multiple sources suggest it is lighter. 160t is too off. 359's OEW is also less than 140t according to real life experiences. 6. For the 777X side, between an MTOW of just 351t, an advertised range of 7285nm for 426 passengers, an OEW of 181t, and a similar/better per seat fuel consumption than 35K etc., things just don't stack up. As no official figure is published, only spectulations can be made based on 777 figures. That said, 779 is already in test phrase, and no significant changes can be done at this point. Boeing should know the figures, so do prospective customers. They seemed to be tight lipped though......

After watching the disaster at Tokyo, I would say absolutely nothing is wrong with the A350. I can not believe how intact thecA350 was after it came to a stop. The fact that the main landing gear and wings were still intact after running through the Dash 8 is a testament to the aircrafts strength.
meanwhile Boeing can't even secure its door to stay closed during flight and just detach from the frame. i would not trust boeing with my safety at this point.
well it is completely built in carbonfiber composites (just like the 787 dreamliner) Aluminum has a melting point of 660 degrees celsius, composites burn at 400-500 degrees but despite that composite maintains it's structural integrity much longer in a fire than alumium which propably is the main reason that everyone had time to evacuate in time. I doubt everyone would have had time to get off if it was a for example Boeing 777 with aluminum. Unfortunately Boeing made the stupid decision to continue with aluminum fuselage on it's new upcoming 777X to save money on development cost which was another dumb choice, makes the aircraft both heavier and less safe.
@@ragael1024 This is my issue with this channel.
It looks very much biased toward Boeing which is understandable if you have a lot of interaction with them.
But really, why isn't there any cover of the plug door issue here yet this video on the A350 for something rather minor.
It's "just a YT channel" but still, it would still be much more honest to just cover issues for both manufacturers.
The MCAS issue was also just lightly touched on this channel with not much blame pointed at Boeing...
@@foadskyflierI'm pretty sure you can't convert an already aluminum fuselage. It's basically Boeing's A330neo. So I wouldn't really call it a "stupid" decision.
@@Tetsuo6995Petter touched on it quite a lot actually when it was going on. You sound like an Airbus fanboy.
I need to make a correction regarding the Trent XWB engines of the Airbus A350.
In the video, I say that the A350-1000 has a more powerful engine, which has a larger fan diameter, of 97 inches, whereas the smaller A350-900's engine has a fan diameter of 84 inches.
In reality, BOTH variants have the same fan diameter, which is about 118 inches or exactly 3 meters.
As some of you have guessed in the comments of the video, this mistake is due to a misunderstanding about the name of the two engine variants: Trent XWB-84 and Trent XWB-97.
My team and I were more familiar with Pratt & Whitney engines, many of which have a number at the end, which denotes the fan diameter, and assumed that this is what Rolls-Royce does, to.
And you know what happens when one assumes… 😔
In reality, those numbers have to do with the takeoff thrust of the two engines: 84,200 pounds for the -84 variant, and 97,000 pounds for the -97.
I really appreciate all of you who pointed this error out as we pride ourselves to always try and bring you the most accurate content possible.

Fortunately only one hole of the Swiss cheese model was poked, and the mistake was caught by the rest of the crew.
All good 👍
Model then variant then rating is very common numbering
Hi, A350 pilot here. Some of the info shared in this video are not accurate. The -84 and -97 have absolutely nothing to do with fan diameters, as the two variants have the same fan diameter of 3,0 meters, or 118 inches. Actually you could even say that the -900 and the -1000 are powered by two variants of the same engine, the difference being that the Trent XWB-84 that powers the -900 has a thrust output of around 84000lb, and the Trent XWB-97 that powers the -1000 has a 97000lb thrust output and a slightly larger core (around 5% larger), and runs a bit faster.
Thank you, yes this was a mistake. Pratt & Whitney names its engines by putting a number at the end to denote the fan diameter, but in this case Rolls-Royce obviously uses this number to denote the thrust output in pounds.
I’m sorry for the confusion and I’ve issued a statement to correct it.

I think we can forgive him for this minor misunderstanding.
Well the accident a Japan showed a very strong airframe, I think this was also one of, if not the most, critical factor that everyone in that plane survived.
agreed!
That goes to the culture of Japanese people! They’re disciplined!
The composite fuselage shatters on impact and it releases toxic fumes when burnt. I don’t think it made a big difference if this plane was a 777 instead of a a350 for example. 777 have had many runway fires and had successfully evacuations, such as the emirates crash at Dxb (which had a longer ecvacuation Time, and all passengers still survived)
My understanding is that this emergency evacuation took 18 minutes so I'm not sure that demonstrates discipline.

Oh man, I'm still bummed that the A380 wasn't enough of a success for Airbus. I so rarely sleep on airplanes since I'm over 1m in height and they're apparently designed / laid out for the other group... But once on a Singapore 380 I turned to my wife and said "are we STILL taxiing?" and she said "we've been airborne for 3 hours, you've been asleep for most of that."
Damn shame.
yes true that
They're also amazingly quiet. I saw one take off in LA, I was impressed.
i really hope you are more than 1m in height😂
The A380 is absolutely the best aircraft to fly in. Quiet, smooth and spacious.
@@Holland41….sre thry still in production? I’d like to fly on one from Gatwick to Heathrow 😂😂
The feature I like about AIRBUS is that it doesn't have the MCAS Rock & Roll feature and the doors don't fall off.
I also heard wheels don't randomly fall off during take-off on Airbuses either
@@MrPrajitura You also don't risk shooting yourself a day before testifying or mysteriously getting an infection if you publicly criticise Airbus. Smh disappointed never flying airbus ever again.
I also heard that pilots don’t stall the aircraft on Boeing aircraft and that Airbus planes are just computers with wings.
If you look back a few years, you find Airbus tails fall off crashing New York City. Airbus claimed the pilot overly used the rudder. My ass. It’s a primary flight control.
Airbus doesn’t need MCAS, they fall out of the sky on their own. Ref: QA A330 flight control computers pitched the aircraft over headed for the Indian ocean, they had stall warning along with over speed at the same time ( same as with AirFrance crash )their EMCAS was lit up like a Christmas tree. This event happened twice in a row. It was only due to the airmanship and skill of the crew that this didn’t end in a total disaster.
The answer is nothing.

All 379 pax successfully evacuated with minimal broken fingernails, evacuated after a 350 (airborne, at landing speeds) impacts a stationary airframe on the deck in Japan - everyone out, with several exit doors blocked, nosewheel absent so front slide too shallow and tail end high. I'd fly on a 350 ANY DAY (but the 380 is still the best IMHO).
To be honest: Whenever I hear a CEO saying "We have to quadruple our profit margins over the next five years," I also hear "The pernickety complaints of engineers and their hairsplitting about safety is an irritation we can't use." Many major industrial accidents are not engineering problems, they are caused by the profit margins being boosted on cut corners." I understand RR needing to compete... but huge airplanes also have huge numbers of people inside.
It's a situation reminiscent of the McDonnell-Douglas DC-10 and its cargo door issue, back in the '70s - best to be cautious when an airplane manufacturer is so singularly focused on profits.
True. And to me it clearly signals that they are willing to compromise on safety because of that statement.
So very true. And even the decision to drop the 350 was purely made from the numbers perspective and by numbers person. Let alone that it's a better plane to fly in 😂
Boeing sold a shed-load of 777-300ERs in the 2010s and most carriers are not yet ready to replace them with new A350-1000 or 777-9. Both frames should see much stronger sales towards the end of this decade and into the 2030s.
Some airlines are more than ready to start changing them. Emirates is one of them.
That’s is very true, a lot of them are barely even 10-15 years old as most sales were around the early 2010s. And the aircraft performs extremely well. pilots love it. The airplane is still cost effective and super efficient even when put against the a350-1000. Sales will pick up tho in the late 2020s
Also the replacement for 777-300 is 777-8, not 777-9. The -9 is significantly larger and is in essence the boeings proposition as replacement for last 747s and even A380s, and has no direct Airbus competitor ATM. So it's little wonder that Emirates chose the bigger plane. And yes, that means that A350-1000 is directly competeing with 777-8, tot -9. And also Boeing chose not to develop 777-200 replacement in 777X generation, instead they'll probably market 787-10 to airlines replacing 777-200, as both planes are extremely similar in terms of capacity. Now the problem here is that while 787-10 is a better replacement for 777-200, it's not the case with -200ER as it has limited range, leaving -200ER operators a choice of go bigger with 777-8, go smaller with 787-9 or go Airbus with A350-900
@@mancubwwa you’re 100% correct. I also think the -200 market segment is in less demand. As it seems the Airlines just go bigger or smaller I.e. the -300ER and 787-9. I hate the 787-10 btw, I think they should have given it a bigger wing to increase the range and fuel. Bring limited to 12000km in today’s aviation market is just too low for a plane of that size.
@@davidajayi1207 I'm not sure if I agree about 787-10, it seems to be primary directad at US airlines for large volume long haul domestic routes like New York to Los Angeles. With no lie flat Buissness you can fit a lot of people on a really fuel efficent airframe and with overland routes no longer than 5000 km and plenty of diversion airports 12000 km range is more than enough.
Speaking of maintenance costs in dusty environments, I used to make (radio system) service calls to a geological survey camp in central Saudi Arabia back in the early 80s. They had a Bell Jet Ranger based at the camp, but it wasn't available to get me out there, so I would have to dead recon across the desert in order to get there in my Nissan Patrol SUV. I talked to the pilot once lamenting that he couldn't fly me in, and he told me that they would only get 12 hours out of each tail rotor due to the dust, and they cost $26K each!
MentourNow is a very Boeingcentric. I think Airbus is doing just fine. And the Boeing build quality again coming into focus with the Air Alaska 737 900Max fuselage damage. One problem after another
Exactly. Boeing just grounded again (MAX9) and he make this video lol
Yeah he loves Boeing and won't even make a video after all the craziness with Boeing that has happened in the last few days
Yes he is biased, I noticed it too
I have noticed the same thing. He really is so biased against Airbus. Makes me not want to watch his videos again.
It's kind of expected that he has sympathy with the same machinery he's operating, ...but despite being a 737 pilot he showed on several videos that he's well aware of how far ahead Airbus and even Boeing tech are compared to the 737 series.
Yes. A350 is excellent. I often fly SFO-Singapore but also flew Singapore-Christchurch recently, all on A350s. But still my favorite aircraft is still the 747-8. But that’s tough to find unless you are flying Korean or Lufthansa.
I believe there's nothing wrong with the A350, never have I seen and travelled in such a well build, safe- and comfortable plane. And like others have mentioned, look at what happened in Japan.
Yeah and on the other end, look what’s happening with the 737 Max. Again…
@@sn4txAt this point I'll actively avoid flying the Max. Nobody knows the extent of poor engineering in that plane.
@@Chopper153 as I use to say regarding that plane, at this point id prefer flying on one made by LEGO.
@@sn4tx Exactly, but this thing that's happened to the 737 MAX seems to be a company wide quality issue so I have to wonder if it's going affect 777 as well in some shape or form.
@@mutkaluikkunen3926 I’m not a Boeing fanboy nor an Airbus fanboy. Do Boeings crash? Yeah so do Airbus. But you are right. As much as I’d like to just keep these uneasy feelings I have towards the MAX (granted I’ll never step inside one of those), with all the issues plaguing other programs one does have to start considering. And hey I’m not driven by paranoia. In the 737 defence, Iots of them been flying by tons of airlines all over the world. So statistically one could say, the 737 MAX isn’t that much of a dangerous plane. Same thing happens in the car industry. Now the issue here is if a certain car model of a specific brand has a chronic quality issue that makes them break down more than the others, at most you gonna be walking or taking a taxi. If a plane breaks
Down … yeah they not gonna park in some random cloud till assistance comes. And as a whole it’s true that Boeing been having some problems across the bussiness. Some more serious than others but still. It shots the reputation and mostly the trust people have on the brand. So yes. Of course as a passenger that likes to check what plane I’ll be flying when I book flights, I’ll be actively avoiding Boeing in general. Doesn’t mean I’ll be 100% safe. But surely being 90% safe beats being 60% safe. Now it doesn’t mean I won’t get on a Boeing plane, if that’s my only choice for the route and time I need. BUT even if air travel is, statistically, the safest way to travel I still prefer to take my chances on a car crash than on a plane crash. And one way to improve those chances is to stay away from those crazy nonsense MAX program planes. That shit should be banned straight away from everywhere. I mean yesterday was MCAS, today are plugs that go “Aight, I’m outta here”. Heck I not gonna be in a future flight that has the potential to show yet another issue with the MAX.
We must also not forget, Emirates have a large fleet of 777-300ER's and 777Fs, bying the new 777X will keep crew familiarisation and maintenance as they all use the core GE 90 engine which yes it's new family on the 777X but still GE, flight crews inc cabin and cockpit crew will be familiar and trained on the current 777 so transitioning to the new one will cost less. It just makes more sense for Emirates to go this route. Also the only aircraft within the size of the A380 is the 777-9.
You can say the same about commonality for the Airbus family of planes. There is even more commonality for air crews than Boeing will ever achieve within the 777 line of products, old and future once.
The statement about the engine is even more surprising after GE had to redesign every section of the GE9X during the 777X testing. The GE9X is the main reason for the delay of the 777X program. Assuming the hot and sandy environment would have no impact on the GE9X is wishful thinking. On contrary, the large 777X contract might bite Boeing and GE big time. There must have been HUGE incentives for Emirates to place such a large order for an unproven, not certified wide body airliner with new, unproven engines. The incentives are a close held secret, but it must be way more than a simple discount. A discount can't cover Emirates risk of having to ground its 777X should there be teething issues like experienced with the 787, or if engine issues surface with the GE9X. The contract must have some writing in it, that is covering Emirates risk, and that again might lead to huge losses for Boeing and GE should their products not perform as specified in the contract!!!!!
I see this as a missed opportunity to switch to better quality planes. Instead, they opted for another long term with an inferior product.
Would agree totally, if Boeing aircraft today, were built to the same standard as Boeing of old. To me the 777x is likely another MAX- Its still the same management.
Just a minor point about the 787. It actually does have bleed air but only for the inlet lip. All other systems that traditionally used bleed air are now electric. I have a friend who is currently in 787 transition training and he was as surprised as I was. And I actually work on the 787 for a living!
Wasn't the bleed air port a modification to solve icing conditions on the inlet lip of the nacel? That modification was made years ago. I had smile when I saw the comments of the bleed air less engine suddenly getting a bleed air port added to it.
@@aquaden8344it’s called the inlet cowl…anti ice.
@@aquaden8344 On the RR engine it uses HP3 air (if I recall) for cowling anti-ice by a dedicated PRSOV. Air-conditioning air is supplied from the CACs (Cabin Air Compressors) to the air-conditioning packs. Wing Anti-ice is electrical heater elements in the leading edge slats. (WIPS).

Hi MentourNow Team, great video! 10:34 I’d like to clarify some misconceptions on the Trent XWB-84 and -97. Online sources indicate that their fan diameters are the same at 118 inches. The increased thrust output of the -97 comes from different internal component designs such as the larger core. Articles also shared that the increased power results in higher temperatures and requires improved cooling. Perhaps the high ambient temperatures in the Middle East also cause lower than expected time on wing performance because of these rotables and life limited parts being affected too.
Thanks for the video it really got me searching and learning more! Cheers!
Thank you for the information! Yes the fan diameter is the same, this was a mistake, it was the internal differences that were large enough for the two engines to end up with different designations.
Hmmm i am not sure about your take on temperatures. Jet engines operate under high temperatures, we, are talking about hundreds of degrees. How much hotter does it get in the desert? maybe 20 degrees or 30F. Thats a big difference for you and I , but not for a machine doing say, 800-900 degrees F? Plus, a lot of their hgih density departures happen at PM, when its MUCH cooler. My point? There must be something else to the story...
I’m glad you went thru all this because the moment he said 87 and 97 inches I was thinking “that’s like PW GTF and CF6 sized fans.
Combustor exit temperatures are well into the >1900K (~1600-1700C) for modern turbofans, well above the melting temperatures of the nickel alloys that the turbine blades are casted from. They require highly elaborate barrier coatings and actively cooled by enveloping the blade in a film of cooling air (which by the way, is already well above 600C to start with). A hot & high takeoff at say ISA+20C could have a significant impact on life-limited parts compared to the nominal flight profiles, so inlet temperature matter much more than you're making it out to be.
When your components area already running at the very edge of what's physically possible, an extra 20 degrees matter a huge amount.
And in case it’s not obvious, the 87 and 97 in the name is the pounds of thrust in thousands.
Very well laid out. We've seen some additional blows to the A350-1000 as of late. The Turkish mega order involved 1000s, Delta is supposedly in limbo for twenty 1000s, Air India reshaped their A350-1000 order from 34 to twenty aircraft and Cathay converted their last five 1000s to 900s a few years back. Rolls and Airbus really need to iron out the issues, especially while the 777X is still in certification limbo. The A350-1000 did win some orders (Air France, EVA Air) but it should be a runaway success because of its availability.
My son has flown to Australia and back from the UK three times in the last fifteen months. He's flown on 777s, A350s, a 787, an A380 and 737-MAX (Singapore to Cairns). His favourite plane by far of all those is the A350 as used by Singapore Airlines. Apart from the 737-MAX which he found very cramped, the one he disliked the most was a 777 operated by Swissair, which he said was very tired and poorly equipped compared to the others.
Thanks for this comment..your son has good judgement about aircraft and I agree that the Airbus 350 (Singapore Airlines) is probably the most comfortable long haul..Have taken it many times from Christchurch-Singapore. and Singapore-Auckland.
We are flying Cairns, Singapore, UK and looking forward to the A350 but not the 737 max leg!!
This
I have the same experience A 350 operated by Thai was my favorite and 777 operated by Austrian the least liked
I flown flydubai 737 MAX 8 and no thanks... cramped, old hull. Maybe good in terms of training, fuel efficiency but its an old style aircraft. I also hated the infotainment. Extremely big and bright screens and as it is so cramped, many will touch your screen by corner when passing by and turning it ON for you when you are asleep. Shitty design.
Hello, I just flew an Airbus 350 4 days ago from TNR to CDG (11h flight time). It is by far the quietest and most comfortable plane of its category.
To be honest, Emirate's concerns are valid.
An engine that can't handle a little sand is an engine that is already picky about how you operate it.
These might be finely tuned machines, but they have to be quite tolerant of abuse all the same.
And if it's "fine in benign conditions" then that means it's fine year round... exactly nowhere in the world.
Rain is not a benign condition, neither is snow sleet hail or sand.
And I don't think humans have a large habit of living far away from any of those things. In fact, I doubt you can find a place on Earth where none of those things happen some time during the year.
It's like saying "This WiFi adapter has a 10 mile range.... under ideal conditions".
But then stating that in realistic conditions it has a range of maybe 50 feet.
Granted, 50 feet might be enough for most people, but they're going to price that adapter based on the 10 mile figure ($$$$$), not the 50 feet figure, because you can get adapters that get better than 50 feet of range in realistic conditions for about $20 shipped to your door.
Point is, everyone that matters to this discussion knows that "ideal conditions" don't exist in the real world.
So to claim that your engine "works fine in benign conditions" when you are talking about an aircraft that needs to operate in ALL weather conditions, even the bad ones, is quite telling that you still have quite a bit of work left to do on your engines.
The real world is INCREDIBLY MESSY in pretty much any way you can think of.
Boeing is fast earning itself a reputation for shoddy build quality. Personally I would never fly on a 737 Max.
Hello Mentor, I just want to clarify that for the XWB-84 engines on the A359, the 84 denotes its thrust rating of 84,200 lbfs and on the A35k which uses the XWB-97, the 97 denotes its thrust rating of 97,000 lbfs, both XWB variants have the same fan diameter of 3m or 118 inches.
The A350 is magnificent. Just did two 14 hr flights from Atlanta to Cape Town and back. The best aircraft I have flown, including the 787,380, 777.
What do you like about the 350 over the others?
Passenger or pilot?
@@CW-rx2js passenger
I notice a huge difference in how my body copes with a flight on a 787 vs A350. The airbus always gives me a nasty headache, whereas the 787 leaves me feeling fine :)
@@jgldev It's quieter, smoother, less prone to turbulence (advanced 'gust suppression' technology) and it's pressurized to an equivalent of 6000 ft altitude (most others are 8000 ft). All round Delta economy was quite comfortale and didn't leave me feeling tired (after 14 hrs) like other aircrafts would. 787 is pretty nice too but I place the 350 above the 787 for quietness and comfort.
Hot and dusty conditions are hard on any kind of combustion engine. I can imagine it's even worse with turbofans that are sucking in enormous volumes of unfiltered air every single flight. Parts made of rubber and plastic deteriorate faster, and lubrication oil will break down sooner in these higher temps. I can understand that Rolls Royce is trying to play it safe with these more frequent off-wing maintenance intervals.
All I can say is that the A350 is the most comfortable longhaul flight I've ever flown economy on.
Makes sense, since the cabin pressure and noise levels are better than the 787 but with the seat width of the A380 (18")

I just don’t think people remember that the 350 is a decently larger airplane than the 787. They’re not really interchangeable. 787 can be better suited for small markets / different business models
There is absolutely nothing wrong with the A350. As a passenger, I view it as far superior to the 787 in the SIA and UA variants.
According to the TCDS the fan diameter is the same at 118". The designation comes from the thrust output. Did you not think it was ironic the fan diameter and thrust output were both the same?
Thank you, yes this was a mistake.
I buy flight tickets now with 35 years of travel under my belt based on the aircraft type...

This hasn’t aged well…. Airbus has just received an order for 70 A350, including 5 freighters.
As others have said, the answer is “nothing”
Translated as: "Boeing offered an entire fleet of 777x basically at production cost."
Same thing as Hawaiian Airlines' 787's last year.
Tim Clark MUST understand how ridiculous it sounds to complain about aircraft out of service then buy a bunch of Boeing jets.
It seems to be the fact that the A350's advanced composite materials and insulation played a part in the "Miracle of Haneda" evacuation that 369 people survived from the crush and fire. Ironically, Airbus has no choice but using this seemingly responsibility-less incident to push their business forward, and I cannot complain as a Tokyoite. Meanwhile, let me pray for the 5 perished Japan Cost Guard personnel in the accident who were on a rescue supply mission for the Reiwa 6 Noto Peninsula Earthquake disaster.
Surely composites don’t have much of an impact. I imagine that the burning composite releases more fumes when burnt, and it shatters upon impact rather than aluminium, which would dent. So I don’t think there would be a major difference if instead of a 350, it was a 777
@@centauri1962 You could say so, but with all due respect, I’m not so sure. About the strength, even as stupid as he could be, the Titan’s owner didn’t dare to make his submersible by aluminum with the same material weight as his carbon fibre. And fumes? One big aim of developing and using such composite materials for the fuselage is flame retardancy to protect passengers inside. The materials of the walls and insulation were carefully designed and layered to serve that purpose. Evidently this time, they succeed in that to some extent, since there were no casualties out of respiratory tract burns and the fuselage structure didn’t give in long after the evacuation finished. The calculated impact and heat resistance of the materials used in the latest airliners like A350 and B787 are slightly but surely better than their predecessors except for such materials’ characteristic unseen time deterioration vulnerabilities.
imagine being an aerospace engineer and after proving ur insane skill in making an aircraft completely safe, people call it a miracle
Cheers and thank you so much for not just covering airplane incidents and piloting insights but also industry usage, needs, overview, and ternds. I appreciate the insight into this industry you provide that outsiders like me greatly appreciate experiencing.
All of the times I have traveled on a 777 was on board of Air Canada, operated by Lufthansa in the early 2010's. Even back then I was quite surprised that these were 6 flights all with Rolls-Royce engines, for me it just didn't make sense for some completely superficial reasons like "American jet with a British engine, when there are other options". I don't believe that Emirates had issues with the RR engines, something else must've gone wrong between them and Airbus, given that as of December 2023 the best economy comfort that you can get is on an A350-1000 and Emirates usually go for it.

The a350-1000 is still doing well. I’m sure Rolls Royce will work on increasing the time on wing performance and I have a feeling Emirates may order this aircraft at some point. Emirates even said they love the aircraft, as long as this issue is fixed it will definitely be considered at Emirates.
I can imagine if the 777X has further delays and if there are problems in the beginning, Emirates will start to shift to the 350.

I thought it was worth commenting on the jet engines operating in hot, sandy climates putting more stress on the engines. A fair number of airlines operating in warmer climates operating the A220 have had to ground their aircraft because of reliability issues with the P&W 1000 series engines. I believe Pratt & Whitney have just now been able rectify these issues ?
As a load planner, the trimming is a problem when flying with full load , many-times I do need to offload cargo due weight and trim, so the fwd hold is empty in long haul flight😂 so I don’t know how the a350f will operate with that trimming. But the a350 family do more fuel economy than others
Mentour, actually pretty good analysis, also it is wort to add: CEO of Aribus resigned during A380 as he said: " as I can not guarantee required reliability of the aircraft we forced to make". Now, when A-380 way earlier stop production, with cost of maintenance over 10000 pounds after each landing, this story its correct, again.

Very good video!! I work as an inspector in the Trent family LPT turbines (IPT in the Ultrafan) manufactured and assembled here in Spain. The 84 and 97 variants refer to the thrust the engine provides (84K and 97K pounds of thrust) . Like all your videos!!
Thanks for the info! Yes this was a mistake. A small confusion between the way R-R and P & W name their engines..! I've issued a statement to correct it.
Interesting! I wondered what the chances of the fan diameter in inches is the same numerical value as the thrust in lbs would be!!
Having flown both I much prefer the a350
First of all this is a fantastic series (as well as the accident series ) and Peter and his crew are to be given mojo credit for a fine productions, the best in their categories hands down. That said, the Trent 7000 is much more like the mentioned difference between the two A350 XWB variants. The Trent 7000 is descended from the Trent 10 (1000 TEN I believe is its moniker) and the TEN is a 75% new engine over the Trent 1000. Once parts counts approach 50% its considered new (disagreement on that, varies from 40 to 60% in various views). Regardless the TEN should be counted as new and the 7000 has a very detached relationship in the 1000 engines. The 1000 itself is no longer made, replaced by the TEN (doing nothing for its attraction on the 787 that the Trent 1000 was never all that well regarded and more so with the failures). Two major RR users (NZ and ANA) have dropped it and are buying the GenX for the 787s they buy now.
As an engine mechanic for 26 years at Boeing Everett, I was always proud to wear my Boeing t-shirts, polo-shirts, hats, etc. out to everywhere I went, NOW I am ashamed and scared to...and it is not even Boeing fault. I blame McDonnell-Douglas, they took one of the finest engineered airline producer in the world and totally turned it into fucking shit!!!
Great video!
One question I have for Emirates - the Rolls Royce XWB might be performing poorly now, but what makes them so confident that the GE9X won't have problems of its own? Being a brand new type
I suppose it makes sense for large airlines to order a mix of Boeing and Airbus jets to have some resilience against reliability problems for a given type, but that entails slightly higher maintenance and crew training costs compared to a single type
I believe there are delays on the GE9X and they have impacted the B777X
The slick salesmen often say things that engineers would disagree with, however in this case I think the XWB did have some new technology which seems like it may come at a cost.
GE isn't in as financial trouble and probably offered a stipend to cover some or all of the extra maintenance costs.
Then you’ll also be more likely to be affected by any issue that comes up.
Hmmmm let's see, the Trent XWB has a dispatch reliability rate of just 99.91% and the GE90-115B/GEnx have a dispatch reliability rate of at least 99.98%, and with all this experience and proven track record GE has, we can see where this is going

Two weeks ago I flew from Sydney to Singapore on an A350. I thought it was fantastic and I'll go out of my way to fly on them again.
The fan diameter of the Trent XWB-84 and - 97 is the same at 118 inches - the difference is - 97 parts are beefed up to deal with the larger thrust.
The reason the A350 does not have a GE engine was because GE did not want to canablize their GE-90 sales with a new engine for the A350. And before GE had a "Gentlemans" agreement with Boeing.
But the question is, when Airbus decides on doing an A350neo maybe in the early 2030s, do you think they'll stick to just RR or will P&W also enter in with their GTF engine but designed specifically for widebody aircraft?
@@CoSmicGoesRacing RR has their own GTF project, UltraFan and Airbus should have be working with them for a while, and chances are the first application would be A350NEO.
@@CoSmicGoesRacing Airbus is a burnt child with PW(A340 GTF/ A220,A320 engine issues). I'm sure they would prefer GE. But without GE they stll may go with PW.

@@miks564 Nope there was a Gentlemans Agreement between GE and Boeing.( google it) That is the reason Airbus teamed up with RR.
I can't help thinking that Emirates are just playing hardball with Airbus and RR. By withholding an expected order and making the 'defective' comments, they will eventually end up with a more satisfactory engine on-wing service interval and probably better commercial terms than if they placed the order sooner, with conditions for serviceability to be improved in due course. Given the long lead times for the airliners, delaying a year or so before placing the firm orders really piles the pressure on AB and RR at little risk to Emirates. In fact, once they do decide to place orders, they can probably use their purchasing clout to jump the line for delivery slots.
Indeed.

@@rafaelwilks Among the latest gen engines though TrentXWB is arguably the most reliable in widebody sector. Even GENx suffered from midflight shutdown and grounding due to icing issues. TrentXWB has none.

@@rafaelwilks That was not caused by design defects, and no subsequent grounding was resulted. Al Bakar at some point threated Qatar would not receive any more GENx-powered 787 before the issue is fixed. He did mooed about Trent XWB but never took a fight against RR up to this date.
@@steinwaldmadchen then how do you explain the superior reliability rate of the GEnx over the Trent XWB?
Similar problem with the L1011 Tristar which was blighted by being powered solely by the RR RB211 engine.
That's something I questioned as well . Rolls Royce being the sole engine supplier for the A350 sems crazy their sakes could be bigger if they could fit another engine from.a different manufacturer.

Talking about the 2023 Paris Air Show, I have been stunned by the number of drones and electric planes on display this year.
Yeah, it seems like a potentially booming industry but I’ve still not seen a good use-case for them.
Well, considering that Air France - KLM (the latter in particular) are switching from Boeing to the Airbus A350, including the 1000 model, I’d say that that airplane is still doing pretty well.
I was so bummed to see KLM retire their 747s but I understand why, quad jets just don't make sense for most use cases.
@@Jebbis, why would an airline operate B744 if they have B77W, which is about the same capacity and range? For Lufthansa due to airline’s size it is slightly more problematic to get quads out of the service.
@@interstellaraviator6437 Lufthansa wanted to replace their still large A 340-Fleet with 787 Dreamliners (at Lufthansa itself and their two subsidiaries Swiss and Edelweiss in Switzerland) years ago but don´t get deliveries from Boeing until today. So they bought now five used 787 from Hainan Airlines in China to simply start their 787-Program - but their A 340 have to persevere, allthough especially their A 340-300 are really aged aircrafts now (Lufthansa: 17 A 340-300 and 10 A 340-600, Swiss 4 A 340-300 and Edelweiss 5 A 340-300). The Lufthansa Group has only six 777-200 (and still three 767-300) at Austrian Airlines, which shall be replaced by ten 787-9, for which Lufthansa is still waiting. Otherwise Lufthansa uses the 777 only in its Freighter Version at Lufthansa Cargo (operating now a fleet of eleven of them and with seven 777-8 Freighter on order).
Lufthansa has a fleet of eight now also aged 747-400 in the Passenger Version (becoming therefore one of the few remaining operators of them) and also a fleet of eight A 380. Both they shall be replaced by ten A 350-1000 and all-in-all 53 A 350-900, from which 21 are delivered and the remaining 32 will be delivered during the next years (the A 350-900 Order includes Orders for Swiss and Edelweiss in Switzerland, too). The 19 747-8 are only round about then years old and shall be operating for the next ten to fifteen years.
That´s about Lufthansa Quads.
KLM and Air France are partners. The only reason they get A350 is Air France...
@@Trancial-x-tion They have been partners for a long time, during which when they placed orders with both Airbus and Boeing, the Airbuses usually went to Air France, and the Boeings to KLM. That has now changed.
Well Cathay recently ordered 6 a350F + 20 options moving away from their all Boeing cargo fleet. Any Emirates show-stoppers are more due to economics rather than engineering. They just didn't get the discounts they wanted.
If a competition is giving a better engine for a lower price why wouldn't they take it? Even Thai has ditched A350 for their upcoming huge order due to RR engine prices despite being a historically loyal RR customer.
The case of Cathay is not relevant in this discussion as the weather in Hong Kong and Dubai is just so different
Yes it's very different and yet by all accounts, Emirates was on the verge of taking the a350K. Did they discover that they operate in a hot and dusty environment in the few hours before the show?
@@aseem7w9 If Thai is giving up those A350 they just acquired they're ditching A350.
And no they were not loyal to RR - quite the opposite. They were known for a messy fleet, ordering almost every aircraft type with engine from all 3 manufacturers.
Also IIRC RR at some point bribed Thai management for orders, so there were some troubled histories as well.
@steinwaldmadchen They aren't ditching the 350 but ditching it for this specific order.
Thai having messy engine choices must be a long time back because in recent history whenever there was RR they chose it, 330 340 772 773 787 you name it, and they probably weren't bribed for every single one of these. GE came for 77W where there was no RR option
The fan diameter of the RR XWB-84 and XWB-97 is the same. They are both at 3 m diameter, the number is related to the max thrust of the engine (84k lbf vs 97k lbf).
Thanks for the video. A very good presentation of the background story regarding engines used in Wide Bodies and the economic and strategic orientation of the engine manufacturers and operators. What I don't understand, however, is the lurid title of the video. Why lose reputation for more clicks? realy? 🤔
I was thinking of the issues Lockheed had with RR when they made the Tristar. That was a great plane but the delay in the power plant killed the sales.
The power plant made the aircraft what it was.........
Ohhh, its never the fault of your lets go Military Company's, this way we get our Money through uncle Sams nose, Millions, Billions, Trillions, ...
Rolls Royce has also stated that they’re focusing on seriously maximizing profits in the upcoming decade. That means very few discounts on engines. The A350 only having the one option for engines, that means engine costs are way higher too. This is part of the reason Delta Air Lines hasn’t ordered the A350-1000 yet despite it fitting well in their structure after they retired the 777 in 2020.
It's clear Airbus made a big strategic mistake to only have 1 engine provider. They should have spent a little bit more for a 2nd option, and would likely have won the bid
@@Matt-YT
Sales of the A350 do not indicate a "big mistake to only have 1 engine provider". Its pretty likely that the 350 will be one of the world's most successful widebodies of all time, without GE. The mistake was that GE didn't push hard enough to get involved in the first place, although Airbus now sees GE as primarily the engine partner for Boeing, and not with themselves. Its GE that will be desperate to get involved with the A350, once RR's exclusive expires, as they look on enviously at RR's success, but I suspect Airbus will stick with RR, as Im sure RR will be transferring tech from the Ultra Fan to engine what will be coming next, the A350 Neo.
Sooner or later, American operators will go with the rest of the world regarding w/bodies, and buy a wholly European aircraft, airframe and engines, without worrying about the politics of buying foreign.
Delta can either pay RR what they're asking for such a competitive engine as the XWB, or spend more buying GE engined B787s, with all the extra costs that entails for them. The choice is theirs and either way will not have serious consequencies for the A350.....
Increasing time on wing is the key to RR profitability improvement. RR's Power by the hour charging means RR picks up the cost of reduced service intervals. So RRs profit improvement plan will likely make the A350-1000 more attractive to Emirates.
Couldn’t Rolls Royce have a number of serviced engines for a hot swap. The delay then would just be the time to take off one engine and bolt on another.😊
I'm guessing they're not committed to promise a ready engine to hot swap, either with high number of airframes waiting for new engines to be installed, or they don't have a high turnaround for new or serviced engine ready
Do you have idea how much those engines cost?
The A350 has been picking up orders very successfully this year including the larger 1000. I wouldn’t expect to see many orders in the n😢ten weeks but at the forthcoming Farnborough show it could be quite interesting to see if Rolls and Emirates have closed the gap but there are also many other order possibilities both new and follow on including BA who are now operating 18 and had options for a further 18! With production set to ramp to rate 12 there should be spare capacity available to satisfy Farnborough demand, interesting times!
The biggest problem is the artificial fuel shortages. Globally we are doing everything in our power to suppress free market oil production and these aircraft suffer for it.
Then there's ETOPS. As there's no more tri-jet models in production, we are forced to make bigger twin jets. The 777x and A350 are perfect examples of that.
The Quad jets are being phased out and only the rich Asian airlines are keeping them.
Thanks for your objective and comprehensive presentation. Rolls-Royce is not a favored supplier with airline executives. High overhaul costs and slow shop turn around times add significantly to the total cost of ownership. Boeing and Airbus have both gone to single source engine suppliers for their B777X and A350-1000 aircraft, which keeps certification costs lower for the airframe manufacturers but removes engine supplier competition from airline procurement.
Agreed. Single source engine supply arrangements are a terrible idea. Give the airlines a choice between engine types!
With the development cost of a large jet engine, few companies are willing to outlay 3-5 billion dollars on a engine that only starts to repay development cost 5-7 years down the road, when orders get split at 50/50.
Look no further than the A380, when General Electric and Pratt&Whitney no bid an engine. It wasn't until Airbus plead with them to team did the Engine Alliance form, and received cost to 60% of the orders.
Airbus love exclusive engine contracts. They get cheaper prices. The customer on the other-hand might be a GE or Pratt operator and shy away from Rolls due to past issues.

@@ant2312I'm really curious, but how is it possible to be an engine maker fanboy ?
@@ant2312
I happen to be an Airbus fan, though not fanboi. Worked flight test for the A320, A300 and A330.
Airlines invest million in tooling to work on their own engines, so they're invested in an engine type.
As for Rolls, their inferior product caused Lockheed out of the commercial aircraft market with the engine for the L-1011. The Trent for the 787 grounded many 787's for over a year. Boeing had their own 787 issues with batteries, but Rolls hasn't been stellar in their large engine market.
I will give them credit for the IAE V2500. The absolutely quietest turbo fan engine I ever worked around.
I bet Emirates was upset with Airbus because AB would not build the A380neo. I think that is the real reason Emirates gave the huge order to Boeing despite the delay with the 777x.
Love the lines of the A350. A beautiful aircraft. ✈
I love its Bandits Mask, Zorro 350, who alters the Dreamliner to a Crapliner.
Maybe stretch some tights across the engine intakes to keep the sand/dust out?
As someone who flies internationally often I'm so disappointed to see the 787 and A350 not being the only aircraft sold at this point. The comfort of flying on a composite airframe with a much better pressure level is unbeatable. I flew to Bangkok last time on an A350 and then back out on a 777 and the A350 was incredibly more comfotable to be on for a long flight.
I haven't flown on the A350 yet but I couldn't disagree more on the 787. Airlines are encouraged into such a dense Y configuration that there is less than no width at shoulder level.
For sure the whole "dreamliner" moniker was a stroke of marketing genius but the aircraft itself is simply awful. I swear people say they like it because they feel they should say so. I'd take a 777 over it any day
@@infidellic Me too. 777 TPac BKK>LAX is just fine, although A380 was head and shoulders, but it's not a fair comparison. Only did 3 hour hops on the A350 into and out of BKK, not very long, but nothing stood out to me as exceptional, other than it was a brand new aircraft at the time.
How much of Emirates trash talking the Rolls Royce engine is to try and "persuade" RR to offer Emirates better terms?!
And for them to roll out the red carpet to get him a “Lordship”
The Brits are no GAGA-Yankees, I think this shoot will miss his target. But there are many things that I thought of the Brits, before there Harakiri called BREXSHIT.
Just a thought but the engine on the B777-9 is not yet proven in airline service so will it be any better ??
Thank you once again for your in depth and unbiased analysis. Educational and entertaining at the same time. The perfect combination.
Whatever might be wrong with Airbus, their "toy" planes have not been recorded diving to the ground or loosing significant body parts in flight recently. Which is helluva more than can be said of "oldschool mechanically controllable" Boeings.
By the old logic of "the workshop where a big mishap recently and loudly is likely the most polished for awhile afterwards" I fully expected the MAX disaster to cause a good deal of right changes over there. Oh was I wrong.
@@JK-dv3qe I think the "recent mishap means all is polished now" effect not working at Boeing is horrifying. It means that as present, leadership, staff, capabilities, - even existential threat problem - which MCAS scandal was - does not cause'em to put their shit well together, and make sure at least for awhile, dust settling, everything Boeing is top-notch.
This is the sign of rot so deep and integral that combined forces of genuine conscience ("we released planes with system that killed 350 people and we need to strive to make up for it") and simple corporate business care ("making planes that crash on their own is not a good prospect neither with regulator nor with customers") are still WEAKER than the fuk-all inertia.
@MentourNow do you believe that the engine is the problem here? What would have happened to Boeing, if after Paris, Airbus was going to get more orders in Dubai also? Would Americans allow such a thing? Do you think politics has nothing to do with it?
Being a life long Boeing employee, I love your content, your natural analysis. Thank you and keep it up!
Long-story short: Rolls-Royce greed, trying to force customers to pay for engine service more often
I was a design engineer for a component on the RR Trent XWB engine, I understood every word of this discussion. I know exactly what you are talking about. I know the difficulties of working through issues is immense, you explained it very well. I know engineers in Derby, where the RR XWB is built and tested. They are very thorough engineers, but there are a thousand pieces to the puzzle that neee to fit to make it work.
For me it looks like RR maybe has to replace efficiency back to durability again which is a politically unthinkable topic.
My first job out of college was working on the phoenix missile. Always loved the the F-14 tomcat!
This is topical...Its design may have saved 300 plus people.
Nothing wrong at all ………….meanwhile on the 737, when 1 door closes another 1 opens. 🤷♂️
Made in the land of opportunities.
I was looking at the sales figures and they are not so bad. 😊The problem for airlines is to chose an old type with boeing or the future with Airbus. It seems that the ones choosing Boeing have an advantage for the next 2-years and a disadvantage for the following 10-15 years. The CEO of Emirates should think about it because he is facing already the competition with Qatar and Etihad. On top of that, Boeing is for me the airplanes to avoid after the disastrous cheating on the 737 Max.
Well, the MAX disaster was definitely a huge blemish for Boeing.
But hopefully they learned from it and the 777 is a fantastic aircraft
I flew first class on A350 with Delta today. Really bad weather, heavy rain, foggy, and windy, but the A350 cut through the weather like they don't exist. Idk how it compared to 777, but it's super stable, and the cabin pressure and air quality is good (barely notice a change).
Was very impressed when i was at the Airport in Dubai arriving in a A380 from Zurich. 777 looked like 737 /A320 in this environment.
You know what confuses me, the A330 Neo, in theory it should but performing way better, but it's sales are really slow. Even though the A330 Ceo is a popular aircraft. Why aren't airlines phasing out the older 330s?
Just as an example, my country’s flag carrier is Iberia, and it’s A330 average age is less than 8 years, being the oldest -200 about 5 years old. This is the case for many airlines, therefore absolutely no need to replace their CEO A330. I assume this is the case of many other airlines in which the A330 plays and important role on their fleets.
They will phase them out eventually. Airbus did the A330neo mostly because a modest upgrade to the A330ceo would be economically competitive with the 787 (there’s even not that much weight difference). They use it to bid against Boeing in competitions, limiting the profit Boeing are making on 787 sales. Dollars not earned by Boeing makes it more difficult for Boeing to claw back the huge amount of market share ceded to Airbus over the past decades. Plus it’s there for when all the A330ceo operators do start needing replacements.
@@abarratt8869that actually makes alot of sense yes
The a350 is seriously pleasant to ride in. 787 always seems noisier.
Mmmm... some years ago I was flying in a 787-9 of JAL from FRA to NRT (eco class) and it was by far the most comfy flight of my life. And I am 6ft tall! Enough leg space, comfy seats and cabin noise from the engines was neglectable. Ok.. I never was flying the A350 before. But 787-9 and A350-900 are very similar.
Orders are one thing, but deliveries are another. Both manufacturers are well behind in fulfilling their current orders, so I don’t think either one is suffering.
Yeah, that’s true. They get paid the bulk of their money on delivery so orders are great but deliveries are better!
@@MentourNow Well one of the manufacturers has to compensate their customers due to a LOT of downtime due to not having their own shit together. And that's Boeing. Not to mention more and more people just don't trust the latest 737 planes anymore.
Which is a shame given that the 2nd and 3rd generation 737's build up an amazing record which is now in shambles.
I wouldn’t be surprised if the memory of the paint/coating delamination issue on the A-350 is still a memory.
Both 787 and A350 are hi tech aircraft. Technical problems and difficulties are to be expected. 777x is a safer bet and with the demise of the 747 and the A380 the 777 is the best large two engine aircraft out there. For Emirates being a large 777 customer already is way easier to continue with the type. It has a better engine too.
Imagine if Airbus renamed the A350-1000 to the A360 hahaha
No A360 will be the Name of the A320 successor...
The A350-1000 seems to be cheaper & more efficient. Maybe Boeing offered a huge discount - combined with a small advantage in capacity and cargo. Both planes are beautiful. Qatar 350X lands here at DFW and its very graceful.
I fly on that Qatar -1000 out of DFW every other month. I think it's the quietest plane I've been on.
@@jemez_mtnEven quieter than A380? I haven't flown on A350 yet.
@@Chopper153 Hmm, yeah actually the 380 is probably the quietest now that you mention it, followed closely by the 350. Then maybe 787, which I didn’t find amazingly quiet.
The A350 series is a clean sheet design with a high percentage of composites and has a much lighter airframe than the Boeing 777. The 777X has yet to enter service and Emirates are taking a lot on faith that it will not have issues and that the GEnX engines offer better operational service than the Trent XWB. If GE fall short then there will be a lot of red faces at Emirates.
Considering that the Trent XWB has a reliability rate of just 99.91%, and the GE90-115B/GEnx have a reliability rate of 99.98%, we can see where this is going
"Much lighter airframe" - Not really, while it will obviously depend a lot on PAX config, using published OEWs of 352k with 369 PAX in 2 class config for for the A351K and 400k with 426 pax in 2 class config for the B779, you arrive at a slightly lower weight of 938 lbs OEW / PAX for the B779, and 954 lbs OEW / PAX for the A351K. So if anything, the 777-9 is actually a lighter airframe for the number of passengers it carries. I would speculate this is down the the 777 aluminum fuselage being an extremely advanced design, coupled with Boeing's 2nd gen of composite wings, while the A350 is Airbus' first generation of composite wings and a nominally composite fuselage that seems to be optimized for ease of manufacture rather than outright weight savings (panelized design with metal frames instead of full barrel monolith).
@@TeKnOShEeP 160t for 35K is way off. Nominal published OEW is 155t, actual OEW seen from various airlines are slightly lower, while with NPS it is 1.2t lighter than ever.
As for reference, 359 and 78J has around the same OEW before NPS, with 359 having a larger wing, higher MTOW but slightly shorter fuselage.
777X in comparison is heavy. 181t is a very optimistic estimation for the 779, while 778 is simply uncompetitive against similar sized 35K. Even as an aluminium frame, 777 isn't exactly known for being light either - 333 is 7t lighter than 772A, and 10t lighter than 772ER. Even the quadjet 343 weighs less. The true strength of 777 though is its heavylifting potential, which helps them avoid direct competition from below.
Regarding wing, it's more like a tradeoff than Airbus "dumb". Boeing's approach means a lighter wing, at a cost of higher wing loading and flexing (which increases drag). Airbus' look stiff, but in return it has low wing loading. 350's wing are strong at climb and field performance. A330/A340 wing was also very good, considering it managed to keep A340's fuel burn not too horrible even with 4 shortaul focused CFM56s, or A330NEO closely match 787's fuel burn with no major changes other than winglet tweaks.
@@steinwaldmadchen Er, what now? I've weighed more than one A351 at several MROs, and none of them were lighter and 345k, most in the 350k range. No idea who is operating them lighter than that, unless it's an all economy config or something. Also, lol, no 787 is within 10k of an A359, even the heaviest -10. The 359 is a much bigger plane, that's why it carries more PAX and has a longer range.
777X is still in development, so not sure how you can say it's heavy when no one has been able to weigh one in service. It has a completely newly designed fuselage, with updated gages and alloys, so I don't really think the classic design from 35 years ago is really a valid comparison. I would expect weight savings on par with what happened on the A320 classic-> NEO, as it's a similar timeline. Aluminum design has quietly gotten very, very good while everyone was jumping on the composite bandwagon. If the released numbers are at all accurate, then it will in fact be a very light airframe, contrary to your assertion.
Wings? Flexy != draggy with any halfway decent understanding of elasticity by the designers. But form drag is a thing, and A350 wings are thiccccc, especially that wing root, mmm damn. The 787 is known to be an extremely slippery airplane that is very easy to inadvertently hit Vmo in cruise, the a350 not so much. TO/Climb performance depends on a lot of factors, but yes, lower wing loading does improve it, so it wouldn't surprise me if the A350 does have a higher max climb rate (don't have the ops manuals in front of me so I can't confirm that). In cruise though, no, you're going to pay the price for that form, and also the extra skin drag. There's a reason glider wings are the way they are- low drag. And again, we return to the A350 wing physically having more material in it- shouldn't be surprising it's draggier- it's bigger.
Fuel burn is a wonderful topic that can be argued until the cows come home, but at max range the per passenger mile fuel economy of the 787 and A350 are very similar 19.5-20.5-ish NMi/lb, the A330Neo is a tad behind at 18-19ish. All of that is way, way better than the poor A340 which, sorry, was in fact horrible, 14-15ish NMi/lb. No magical wing design (which it didn't have) is getting around the fact that quad jets inherently burn more fuel than twins, for obvious reasons.
@@TeKnOShEeP You seemed to also mix up things
1. A340 is a 90s design, of course it can't compete with modern designs like 787 and A350. And it is not great when comparing with A330 of same size, its sister twinjet. However it actually burns slightly less per trip than similar sized 772. And the trick is a lightweight frame and good wing, combined with some other compromises.
2. A thick and stiff wing doesn't mean it's bad lol. And that is reflected by A350's high lift / drag ratio. A350's wings are efficient lift generators, and L/D ratio is in fact better better than 787s. A larger wing area also result in lower wing loading, allowing the aircraft to climb to higher alititude earler for more efficient cruise, and lower thrust for takeoff (while 77W and A321NEO is the opposite). TrentXWB-97 actually has 10klb less thrust than Trent 898 that powers 773, despite 35K's higher MTOW. The wing is approprate for a heavylifter with long range flying in mind.
3. A330s are also surprisingly competitive at that front as well, in fact LD ratio also slightly higher than 789/78J, hence why Airbus kept the wing largely untouched when developing NEO. (They aimed ~2% behind 787, at least for 339 vs 789). As an older metal wings there are more compromises on the 330 side, and cruise speed is one of them. But that's not the point - the wing was extended significantly after the initial SuperFan for A340 was replaced with CFM56-5C, to compensate the worsening TSFC.
4. The wing flex of 787 does mean lower L/D ratio by reducing the upward lift generated. It's not desirable, but it's also a result of tradeoff. In fact 787's wings were more optimised for -8, they decided not to make bigger wings for -9 and -10, for the sake of production cost and weight savings.
5. According to ACAP published by Airbus, the highest MZFW found on 35K is 223t, while structural payload is at max 68t, which translates into an OEW of 155t. And according to pilots working for Cathay Pacific (a heavy user of both 77W and 350), their 35K consistently load better than 77W, while multiple sources suggest it is lighter. 160t is too off. 359's OEW is also less than 140t according to real life experiences.
6. For the 777X side, between an MTOW of just 351t, an advertised range of 7285nm for 426 passengers, an OEW of 181t, and a similar/better per seat fuel consumption than 35K etc., things just don't stack up. As no official figure is published, only spectulations can be made based on 777 figures.
That said, 779 is already in test phrase, and no significant changes can be done at this point. Boeing should know the figures, so do prospective customers. They seemed to be tight lipped though......
Flew last summer from DFW to LHR on A380 and it was packed. Flights between hubs like DFW to LHR/CDG/FRA makes a lots of sense.
Well I think the recent Japan incident showed how well build it is + its not a Boeing XD
My frequent flyer friend, American an strong boing fan for most of his life, is now a big a350 and a321 fan.
