I see you guys got me beat as I spent 30 years at Boeing on the 747, 767 and 777 line and installed the canoes on many of those planes. Those air pods were known in Boeing as canoes. Even Mentour briefly mentioned the air pods as canoes at the beginning the video.
I was the buyer at BCAC, group T5634, in the POP department, for the 767 trailing edge flap support fairings (called "canoe fairings") in the early years of the 767.
The level of Professionalism on this channel, and the Mentour Pilot channel is overwhelming in my opinion. It has been my good fortune to listen in and watch. Thank you Sir.
Really awesome that a pilot knows so much about the engineering and mechanics of the machine they’re flying. I’m no pilot but I really enjoy these videos. Thanks and keep it up!
Yep, pilot’s are expected to know their aircraft inside out, even private pilots have a technical exam to pass, airframe, systems, fuel systems, navigation equipment etc.
I haven’t done a type rating but know pilots who have. Mentour knows an exceptional amount but I think you need to learn a good 75% of his knowledge to get typed on an airliner. All pilots get into the weeds during training. Some of us forget a bit. Mentour learns more.
The best airline pilots are often former military pilots or mechanical engineers... Not only do they understand how to fly, but they understand the physics of how and why things are happening...
Old saying with a new variant:"There are many old pilots, and many bold pilots, but not too many very-clear-communicating pilots" - you are one. Well done and very much appreciated. Liam
As a non-pilot I love “how it works” videos! As a licensed commercial driver I recognize the necessity of a pre-trip inspection and the importance of a working knowledge on all of the systems and sub systems to be checked. So even for pilots and aspiring pilots, videos such as this could be invaluable! I vote you continue doing more of these type videos! I see now that I’m a lil late to the party tho...lol
I am an old civil pilot , just retired and of course I enjoy your videos. Congratulations for your fine work and your time too. Best regards from Montevideo-Uruguay
Even though English is obviously not his first language, he is still very clear in explaining a concept without stuttering. That is a job well done that is tough to do.
Nobody gives a rats ass what his first language is!! he speaks perfect English!!, there are over fifty countries where the official language is English and in those countries, they have their own accent, some of them even speak more than one language, not like those self-centered Americans, why can't people just appreciate and enjoy, when someone took the time to post something informative??
He has a VERY typical Swedish accent, which is fine. Great vocabulary and fluency. I just wish that he would stop pronouncing "thrust" as "trust". Keep up the good work!
@@shanebond550 What I refer to, that you completely missed, is an educational concept. Many use English words in a very vague sense to communicate a concept. His English is so clean and to the point were he can explain a complex concept to an uneducated audience and still have them learn something from him. The ability to do that requires a very refined communication skillset. With some, listening to them is a painful ordeal as they meander. He is clearly educated in his ability to explain a concept to be immediately understood as opposed to contemplating his presentation at a later time. There are not that many who can speak so clearly and is almost entertaining to hear any presentation.
The more I watch this stuff, the more I come to believe that in flying, your life is as much if not moreso in the hands of the mechanic than it is the pilot.
Actually there's no real pilots any longer. They already are semi-robots because the new technology does almost the all lot. Real pilots are in the Airforce. Commercial pilots have poor skills.
Antonio most pilots received their training in the military, many are retired from the service after 20years.I suggest you check it out before you spout off.
@@robertnielsen2461 most it doesn't means all! Your own words are conflicting. When the fighter pilots turned as commercial pilots obviously they loose flying skills. Like it or not, fighter pilots have better flying skills.
Yes PETER PUTS UR HEAD IN ORDER, WITH NO FLAP U SAY LONG RUNWAY WHAT IF IT WAS SHORT RUNWAY WATCHED SMALLER PLANE LAND WELL IN TREES 50 SOULS BUT PILOT TRIED AX ON HIS WINDOW HE DIED HAVE THEY GOT QUICK 737 FAST EJECTION NOW? PAINFUL HOW HE PASSED.(WOW Impressive ur plane used by military & .issues too.always give u thumbs up,ur huge in USA but in dark on " knots other European ways of numbers re hours etc can u add English 2,great Voice Hand gestures help understand what u say as u speak quickly..10+
I REALLY enjoyed your video. My daughter has started a phd program in atmospheric aerospace engineering at the U of Texas and I try to check out aerospace broadcasts like this so I understand what so intrigues her. You are a great teacher: clear; you speak in simple terms, and when you personalize your broadcast with your stories of problems you have encountered as a pilot, it makes the understanding so much easier. Thx.
I'm only an airplane enthusiast and I really like your videos! To me they're spot on. I really like understanding the technique behind plane mechanisms. Thanks again for all your videos! Charles
I'm an employee of the company that builds 737's working in wing systems cc128.We install flaps,slats,engine struts,landing gear actuators and all fuel systems.I have personally installed hundreds of flap tracks,flaps and flap track fairings.I'm also the lead mechanic on 737 P8 and have worked on over 6,500 airplanes including 707,737,747 and 757.If you have any specific questions about 737 wing systems manufacture or operation feel free to ask them.
Found this channel today and subscribed right away. Been subscribed for about 2 years to 74 Gear and love Kelseys’s videos Now I have a new channel feeding. My dad was an instructor polot with Western and Delts doing recurrent training on 727’s and 737’s. I got to go down a couple of times to LAX and fly the full motion simulators. He started in the Air Force and flew B-25’s, -26, and then -29 then end his Air Force career in Vietnam in B ‘52s. My hero.
Your english is outstanding and your delivery and competence in explaining complex information is second to none . Well done , if you retire from flying , teaching is waiting for you in any area .Keep making these amazing clips .
5:30 I love your "Flap Skew sound!" I know its been said millions of times but you really do a great job making your videos! Your in depth explanations and examples really help in understanding what is going on! Thank you so much for all the time and hard work you put in these videos, it is very much appreciated! Take care and all the best for you and your family! 👍from the USA!!
Video gets a like: - Title posed a question that piqued my interest but I didn't want to spend to long on it - And you gave the answer to the level of detail which satisfied that interest in the first couple of minutes Thank you for doing it like that and not trying to bait everyone to watch the entire video when they may not have the time
We all do. Teachers are busy spreading socialism and racist propaganda... thats all they do. Thats why our kids cant think or read well or deal with science. No new welders or plumbers or carpenters ... kids are told how racist they are and that the environment is doomed. Yet the leftie leaders have massive houses and fly everywhere. And dont wear masks. Thats for the lowly idiots to do.
They are, but they have a class full of kids and some dweebs choose to be twats and the teacher spends the lesson dealing with the dickheads while you miss out on what they could impart. It’s easy on RUclips, this guy can talk and his audience can’t affect anyone, so you get a one on one. Just think before leaping. Teachers cop it in the neck because the government keeps the idiots at school instead of pissing them off to boot camp or disciplining them.
Thank you for your informative videos, Captain, I absolutely love the B- 737. I’m a US Army Veteran, and a G.A. Pilot, and the nephew of a US Air Force B52 pilot, (and several other pieces of Air Force equipment). I’m very grateful for the knowledge of any instructional videos or face to face aviator knowledge shared with me. Flying has always been my passion since childhood. I’m absolutely a free spirit when I fly alone, and I absorb what I can to fly safe and to always be prepared for any situation. God Bless You, Sir, and thank you for your contribution to aviation. Hand Salute Rendered.
Yep! I love the depth on this channel. I knew it was the flaps mechanism, but then video of actual motor for the flaps in operation, stuff about FSEU and other flap related systems. Same with the "Why no main gear doors on the 737" video. Simple answer would suffice, but here's all this extra information on it. Top quality content.
I agree, not to diminish Captain Joe- he does a great job- especially with all of his analogies. Mentour Pilot acknowledges everything and always makes sure you know almost everything.
They both target different audiences and both do a good job making videos with their target in mind. Captain Joe targets the general public, while Mentour targets enthusiasts, pilots in training, current pilots, etc.
I’m not a tekky person and I don’t understand the basics yet, but I love the mentality of Captain Mentour. Really focussed and well-argued. Gets to the reason why and doesn’t indulge in any kind of exaggeration and pointless window-dressing. I wonder how closely these video explanations replicate the classes the Captain’s lectures gives to his actual trainee pilots?
@@ronaldpellet854 Can you give me A Chance for Work I do Asset Manager, Accounts Manager, Transfer Handle, Audit Purpose I Do work with Safe And Secure
I've watched those flaps extend on many an airplane coming in to land, I am always amazed by the rigid strength they have as they get buffeted by the air. Now I know why they are so strong.
Captain, every one of your videos on aircraft systems has been highly informative. I am no longer a young man, and an ATP is not in the cards for me. Just the same, it is heartening to see you lighting the way for prospective pilots. Please keep up the good work!
My favourite part of this video is at 5:30 I could listen to this for hours! P.S. Keep up the good work! I love your channel, you answer questions I’ve wondered about for YEARS - JD, Montréal
As an electronics engineer myself, though retired, my first job back in 1972 was in aviation. I was doing avionics servicing in general aviation from the smallest planes up to cargo DC-4s and a couple executive jets. One of the reasons I got hired at that as my first job out of school is that I was an aviation groupie. I knew those pods were the flap actuators but did not know before how they worked. I am sure many will find the tech stuff boring but for me, bring it on. You cannot get too technical with me at least.
@@redblade8160 I never worked on aircraft that had flight attendants. The Cargo DC-4 flew supplies to a uranium ore mine in the middle of nowhere and brought back tightly sealed barrels of uranium ore. It was general aviation work. Where I was dispatched to planes around an industrial airport and never met the flight crews or plane owners. So your assumption of getting involved with gay stewards is an entirely unjustified assumption.
I was a little bit nervous about flying. I knew deep down inside that pilots very well knowledgeable however turbulences, take off and landing still put me on the edge of my seat. Now, after watching your videos about all these, reassure me about flying. Thank you for a job very well done.
I was a Jet Mechanic in the US Navy during the Vietnam War and worked on Pratt&Whitney TF-30 P408 engines. After looking at those photos of the Fearing gear assembly I forgot how much safety wiring we had to do on Jet aircraft engines and any other moving parts on the aircraft. Every nut and bolt and fitting were safety wired to each other to prevent the nuts, bolts and fittings from coming loose in flight. The real fun was safety wiring the engines combustion cans at the center of the engine. There were always a few combustion cans that were hard to get at and you had to use a mirror to see what you were doin. Thus you were observing a reverse image in the mirror while wiring the combustion can bolts. It was a challenge and took a little practice.
To complete what you said: these trailing edge pods also reduce the wave drag which appears at high speeds. This is why they are so bulky (they could be slimmer if their role was only to cover the flaps mechanism). When this aerodynamic effect was discovered, a few aircraft like the Convair 990 were designed with dedicated "anti-shock bodies" on the trailing edges. Aircraft manufacturers later found it much more efficient to combine them with the flaps fairings.
Shocks begin to form on the upper surface before the bottom. Obviously because the upper surface is where the air accelerates. The lower surface on modern aircraft such as A320 family and forward use the super critical airfoil that incorporates a trailing edge cusp to also mitigate the formation of shock waves. I would be cool if the fairings stayed on the upper surface like the 990. My intuition says that took up wing area on the lifting surface.
Antoine Bonnet Except,.. That doesn't come in to play here. Good Explanation of why it would at mach-+. But these, as in most Boeing "Commercial" Aircraft. Is for ease of removal and maintenance. And hence their dimensions. Tolerances at less than Mach, are less critical. Just a simple explanation from a 49yr Boeing engineer.
@@tonybalogna123 But these are just aerodynamic fairings to cover the flap tracks. And they are only held in place with a single row of screws around the top of the fairing. Which in itself shows they don't normally experience much turbulence,.. normally. And why they were a bit larger than they technically had to be. Again, for ease of maintenance too. They are there to protect the flap tracks system from dirt and debris. And keep crap out of the gobs of butter lube within. And those are Technically Called "Torque TUBES",.. not torque rods. You have to be Good at Safety Wiring those, especially on the 747. A torque tube nightmare. Trust me 😬 Those fairings on the 747 were big enough for a 12 person Canoe 😂 ... if you screwed them together of course 😊 The 47 was my fav. And in the old days. If you know what final assembly is. Final Assembly is were you bring all the aircraft sections together. Body, Wings, Gear, Control Surfaces, Electrical Systems etc. And assembly the complete airframe. Minus most of the interior, engines, paint,.. that sort of thing. Anyway. We were assembling a 747 every 3 days, with no travelers (100%) for almost 3yrs. Till the cycle changed again. We were building them faster than they knew what to do with them 😂 Good Times. We had fun 🤗 Which reminds me of a term few people have ever heard. "Crease Backup". You get a ⭐ if you can find that one. ...other than this comment 😏✌️
@@My-Pal-Hal Love the explanation. Not gonna lie, the "anti-shock" explanation does sound a little sexier and exciting than just an ol' safety cover for the flap mechanism... but I've asked a few engineers now, and they all pretty much say the same thing you're saying.
Modern airliner engineering is a marvel. The engineering behind the passenger experience is unbelievable. Thanks for taking the time to explain to us all of these aircraft features. Your channel is great man keep it up!
Always enjoy, listening to you no matter what parts of airplanes or crashes, you’re talking about! I particularly enjoy the “sound effects” in this episode!
So amazed and proud of how far this channel has come 👏👏🥂🥂 I'm going back to these older videos to watch what it is I missed all these years ago 🙏😘 Well done Petter!!!
I remember the first time that I boarded a plane back in 2005, i was 5 and i thought they were there to make the airplane float in water 😂😂. Don't ask me why. Great video as always Petter
My old man was a recirculating ball screw designer. I grew up with this stuff... He and a friend designed the screws for the C5 Galaxy kneeling system. They are HUGE!!!
I cant list any improvements to make since there really aren't any improvement to make, the channel is flawless for what it's trying to achieve, which is inform people on various topics in aviation. more cockpit videos would be interesting but as far as content goes, don't change
I can, literally every video you has a simple question and an absurdly long answer that could be summed up in a paragraph. Have that paragraph in the description.
When I was a kid, we called them fake engines... :D Thanks for teaching us about this subject. I know nothing about aviation but this channel has been so interesting to follow!
Mentour pilot,(Petter Hornfeldt) love your videos in your unique Swedish accent. Used to be a student pilot in the late seventies.. Now i am into own Pharma business. But the flying bug has never left me. Your videos are so detailed and informative.. and explain all possible doubts about the technicalities in commercial aviation. Thank you once again. Keep doing your Great work.
I am not an engineer but I have curiosity to learn something about planes. So I am learning. Herein , the video is simple, pursuassive, any passionate learner can learn easily. It's good and helpful video for the person like us. - Damodar Boruah, Author Born To Do Big, India
I love watching your videos. I have been in aviation maintenence for 40 years and love seeing a pilot know so much about all the systems in an aircraft. Keep up the good job.
Speaking of landings... (sorry, but this might be a bit off-topic, but I was hoping you might be able to steer me in the right direction nonetheless...) I was a passenger on a plane in May of 1998 that had a near-miss with another airliner, at LaGuardia. I am talking about a big airliner, landing on runway 22, coming within 20 feet or so of another that was departing on runway 31. We went over the departing plane, as our pilot abruptly pulled up and gunned the engines, calmly announcing that we were going to go around to take a little sight-seeing tour of downtown Manhattan, which we did do (aside: our view of the WTC led me to imagine what a terrorist might be able to do to the WTC if he had a plane this close -- as close as we were -- to it). I realize this was some time ago, but it was such a significant event that I cannot get it off my mind. Since I did find a very similar (but not exactly the same) occurrence that also happened at LaGuardia, within the same timeframe (Friday, April 3rd), I thought that this might have been it, but it isn't happen at the right time (it was at least four weeks, and perhaps as much as six weeks earlier). I know the date of the near-miss that FAA has on its website (Friday, April 3rd, 1998) and I know the date of the event that I was attending, the '98 SAME Conference (Society of American Military Engineers) in midtown Manhattan (19th-20th May). From memory, I believe that I took the flight from St. Louis Lambert to LaGuardia I have found another event that was very similar in the FAA logs, but it just was different in a few specifics, and possibly off on the date by several weeks... I have reason to doubt this was the one, but still think it probably was just yet another near-miss at LaGuardia. Apparently, this incident was never reported or recorded. I didn't report it. That's what's interesting to me, there were so many people involved, pilots, tower controllers, passengers, and the incident so potentially horrific, it surprises me that there is no documentation of it. Any way to remedy this, at this late date? Or, specifically, to find out if there might not be some record of it, after all, in FAA ledgers? Thanks.
@@polish001airigami5 I wish for you to find out how much fuel for a journey. See how much it is and how many containers you need. Where is it? It's not on the plane. 9 buses of fuel, its impossible. No fumes of fuel burnt. Look at the zeppelin, that travelled around the world, ON AIR. no gravity. Just electro magnetism.
Yes, the technical aspects of aircrafts is gaining information that I refer to as a puzzle to be filled in with each piece of the puzzle. In this video in addition to seeing what these pods do, and the approach used to solve problems that can happen. I also realized why some fans addressed the question if the aircraft could be armed? It does have that appearance if one knows they are there. Continue doing what you do you do it very well as your fans have so often written. You do space the technical with incidents that happen that is also a source of knowledge that blends our learning and interest.
In 1971 the track roller bearings on the 737 wing were causing problems. They would lock up, shear the cotter pin holding the retaining nut, unscrew the nut and leave the bearing lying in the nacelle you see on the cover picture. There was a bulletin on the 737 to re lubricate the track roller bearings every 50 hours. I was a Sales Engineer working for McGill Bearings who manufactured aircraft bearings. Boeing was my customer. Larry Blakley, structural engineer assigned to the 737 wing asked me to become involved in the problem. The application and problems were similar to fish cleaning machines in Alaska (manufactured in Seattle by one of my customers) which had been solved by my efforts With support from McGill engineering dept, I proposed a solution. Last I heard, the test aircraft at United had flown 7 years without lubrication or failure. I believe my effort contributed to the success or the 737 aircraft. This scenario would not happen today because the mechanism has been replaced by computer software. Did I get rich, no, I was doing my job. McGill Bearing made a bunch of money! Iguana
I really like having a pilot explain all the different functions on an airplane. I like knowing these things; it makes flying so much more interesting.
Keep making these videos. They are very interesting. I for sure am getting so much out of them. I find aviation fascinating. I have learned so, so much. Thank you.
Nobody normally talks about these subjects so we go along flying or not flying on planes not knowing anything about flight or how it operates. In the blind.
Flying an aircraft is still a dream for me but being with you through your videos simply indulges me so deep that i sometimes feels like living my dream. thanking you and waiting to see you in next video.
Lol not so much when you realize how many moving parts are on a jet airliner and statistically the more moving parts you have the higher risk of failure you have.
But if it makes you feel better you're more like to die by choking, drowning, or in an automobile than you are in an airplane. Statistically it is to date the safest way to travel. Lol
@@tobylots ? I'm not sure what exactly you're saying here? I worked on powerplants of jet aircraft for a long time I know how the religious safety checks as you call then go. Lol Even with that no matter how maticulis safety checks are that doesn't change the fact that the more moving parts something has the higher chance of failure it will have.
@- haha gosh dam I guess I have to prove I've worked on jet power plants to some nobody grammar Nazi on RUclips. FYI I was an aviation machinist mate that worked on legacy, super hornet, and growler fuel cell and powerplants at both I level and O level. I've literally rebuilt jet engines from the ground up and tested them on test stands and in aircraft.. I've done everything from full breakdowns and rebuilds to routine maintenance on every single type of F18 ever made from A to G. I'm very well acquainted to how maintenance is performed in the aviation industry.
I know this video is years old, but just wanted to say that back in the day, I got my Enlisted Air Warfare Specialist (EAWS) on a P-3 Orion. I never got to see the P-8's. And yes, you could also arm the P-3s. Thank you, ET1(AW) Hargraves
I just wanted to say, Petter, that the Mentour Pilot videos are so much better than their competitors. I used to fly frequently as part of my work, flying transatlantic and within Europe, so I learned a reasonable amount about aviation matters. Your videos, however, show me that I knew very little in reality and understood even less. Please keep up the good work!
It’s impressive to me how effective you are at explaining complex topics in simple terms - especially when I consider that you are not a native English speaker. More information on the various systems of the B-737 and the military version of the aircraft would be most welcome. Thank you for the significant effort and care that is so evident in your videos.
These pods under the wing are the trailing edge anti-shock bodies used on the Handley Page Victor bomber, commonly referred to as "Küchemann carrots" invented by Dietrich Küchemann, who worked for the Royal Aircraft Establishment. They greatly reduce drag. Kuchemann is also credited with the Coke-Bottle 'area rule'.
You're 100% right. This isn't really covered in the video, but the reason the pods are where they are, and they are the shape they are, is due to the Transonic Area rule (as the Coke-Bottle rule is properly called). Most 3rd year Engineering students learn how to derive this rule when studying supersonic flow. Basically, supersonic flow can "choke" when "turned" too much by a rapid change in body geometry. From this concept, the ideal "cigar" body can be derived. This is more obvious in some planes like the DH Comet, where some of these concepts were implemented for the first time.
the flap track farings in slang are often called "canoes" due to their appearance. the forces involved by such actuators is quite significant and the reason why such are "pinned" during maintenance operations to avoid potential fatal accidental actuation during maintenance operations (such pins being treated as surgical instruments during medial operations and carefully accounted for so as to prevent being left behind before aircraft is put back into service)
I was on a flight where one of these “pods” was loose. When the flaps were down the pod shaked wildly. When the flaps were up the pod was hanging down but not shaking. We landed ok but it scared a lot of the passengers.
Yet again the author is full of shit. Pods wouldn't create "enormous amount of drag". The most important parameter when calculating drag is the area measured from the direction of air. When packing in something you increase the area, thus the drag.
@@RUclips_Stole_My_Handle_Too You misheard him, rewatch it and turn subtitles on starting at 1:30. He says "the pods are there to *streamline* the air as it's flowing through" and "IF the pods *were NOT* there, it would cause an enormous amount of drag." Literally says the pods decrease the drag. The trailing flaps cause the drag, not the pods. The pods support the flaps and decrease drag, as well as help make sure the flaps are extended equally to create even lift/drag on both wings.
WOW! So much detail, I'm just a regular guy who flies on their annual leave but this is SO interesting for the curious holiday maker. Thanks for sharing.
2:07 I thought the flaps, in addition to those things, were also supposed to increase the stall AOA by allowing a small amount of the higher pressure air underneath the wing to blead through the gaps between the flap and the main wing in order to prevent flow separation during landing, when a higher AOA is needed due to the lower airspeed?
You are doing a really good job explaining the various system of the aircraft. It's really useful for me for passing my Easa modules for Aircraft maintenance licence
I fly a lot. I'm amazed at how LITTLE the average human knows about what even makes a plane fly. Most people don't know how ANYTHING works. I think people should at least take a small interest in how basic things work in life. Nice job explaining this.
Very perceptive answers,,for years I,ve been pondering over those pods, and no doubt I,d continued if not for you putting yourself as the pilot into the curios shoes of your patrons,,thanks 👍
The US Military plane was a US Navy P-8 Poseidon, they are modified Boeing 737-800ERX’s that are designed for ASW (Anti-submarine Warfare). They carry torpedoes, harpoon anti-ship missiles, and depth charges.
+Reese McClain - And the P8 is also operated (with slight variations) by the Indian Navy and the Australian Air Force. It has been ordered by the Royal Air Force and the Royal Norwegian Air Force. The latter has mighty good reasons for submarine interdiction.
Wow, I’ve always wanted to know this myself, as I fly frequently. Passenger jets are a wonder of technology, but I’ve always been fascinated by just the design, thought, and engineering that goes to just the wings structure alone.
Wow. Below is my comment from 8 months ago. Now I am a huge fan of Mentour Pilot and I wouldn't write a comment like that. Even If all this video could be answered with a single sentence ("These are flaps extension mechanisms.") for me 8 months ago, now I like the fact of extending the insight into the mechanisms. And I don't mind a little bit of slow paced overexplanations from my current favorite RUclipsr.
I was a passanger once when flaps malfunctioned and we landed with a bit more speed. You have great videos on tech that has always interested me but the stuff I never botherd to look for and understand better. :) Getting just enough deeper into the rabbit hole from my current base knowledge. Thanks yt for offering these after searching basic stuff on airplane and helicopter flying :)
8:50 It's a big deal if the runway is very short, f.ex like in Funchal Madeira. It is extended but back in 1979, it was kind of dangerous. I remember we stood waiting for the plane while the pilots did some rounds back and forth before, we were allowed on board. The pilots tried to find the right speed without passengers, so they better knew how fast they had to go with passengers. It was a Boeing 727.
Those are experimental new seating spaces for RyanAir, reclined seat only.
Id try them!
“Pod Seats” also commonly known as “flying body bags” in RyanAir’s case...
Since they will lie-flat, there will be additional charge.
LOL they would never allow passengers to recline that much.

I worked for Boeing for 39 years and made the flap mechanisms in the pods on all the Boeing jets.
Great work from great people
I also worked at BOEING for 39 years I worked in the machine shop,and saw a lot of theses parts in the shop
I worked in Everett
Relax everyone. Tom was well-supervised. 🤣
I see you guys got me beat as I spent 30 years at Boeing on the 747, 767 and 777 line and installed the canoes on many of those planes. Those air pods were known in Boeing as canoes. Even Mentour briefly mentioned the air pods as canoes at the beginning the video.
I was the buyer at BCAC, group T5634, in the POP department, for the 767 trailing edge flap support fairings (called "canoe fairings") in the early years of the 767.
The level of Professionalism on this channel, and the Mentour Pilot channel is overwhelming in my opinion. It has been my good fortune to listen in and watch. Thank you Sir.
Calm down, this isn't charity work.
This is the mentor pilot channel
I prefer Captain Steeeeeve Fly safe
Really awesome that a pilot knows so much about the engineering and mechanics of the machine they’re flying. I’m no pilot but I really enjoy these videos. Thanks and keep it up!
I am not sure if thats common...
More and more nowadays, he is expected to.
Yep, pilot’s are expected to know their aircraft inside out, even private pilots have a technical exam to pass, airframe, systems, fuel systems, navigation equipment etc.
I haven’t done a type rating but know pilots who have. Mentour knows an exceptional amount but I think you need to learn a good 75% of his knowledge to get typed on an airliner. All pilots get into the weeds during training. Some of us forget a bit. Mentour learns more.
The best airline pilots are often former military pilots or mechanical engineers... Not only do they understand how to fly, but they understand the physics of how and why things are happening...

You have messed around with that saying and created your own version (and it's pathetic).
As a non-pilot I love “how it works” videos! As a licensed commercial driver I recognize the necessity of a pre-trip inspection and the importance of a working knowledge on all of the systems and sub systems to be checked. So even for pilots and aspiring pilots, videos such as this could be invaluable! I vote you continue doing more of these type videos!
I see now that I’m a lil late to the party tho...lol
This is the kind of teacher I want. Detailed and realistic 5:30 7:55

Nobody gives a rats ass what his first language is!! he speaks perfect English!!, there are over fifty countries where the official language is English and in those countries, they have their own accent, some of them even speak more than one language, not like those self-centered Americans, why can't people just appreciate and enjoy, when someone took the time to post something informative??
He has a VERY typical Swedish accent, which is fine. Great vocabulary and fluency. I just wish that he would stop pronouncing "thrust" as "trust".
Keep up the good work!
@@shanebond550 What I refer to, that you completely missed, is an educational concept. Many use English words in a very vague sense to communicate a concept. His English is so clean and to the point were he can explain a complex concept to an uneducated audience and still have them learn something from him. The ability to do that requires a very refined communication skillset. With some, listening to them is a painful ordeal as they meander. He is clearly educated in his ability to explain a concept to be immediately understood as opposed to contemplating his presentation at a later time. There are not that many who can speak so clearly and is almost entertaining to hear any presentation.
He actually pronounces English the way It Is ouhgt to be.
I've been a pilot with Spirit air for nearly a decade and found this video very useful, thanks!
The more I watch this stuff, the more I come to believe that in flying, your life is as much if not moreso in the hands of the mechanic than it is the pilot.
I have to think many pilots agree with you. Too many crashes have been due to faulty maintenance procedures. This more often than faulty design.
Actually there's no real pilots any longer. They already are semi-robots because the new technology does almost the all lot.
Real pilots are in the Airforce. Commercial pilots have poor skills.
My Dad has been an aircraft mechanic for 40 years and he says Jet Engines are easier to work on than cars...

Video gets a like:
- Title posed a question that piqued my interest but I didn't want to spend to long on it
- And you gave the answer to the level of detail which satisfied that interest in the first couple of minutes
Thank you for doing it like that and not trying to bait everyone to watch the entire video when they may not have the time
Though retired I still love watching your very educative videos ...
I wish my schoolteachers had been as interesting, knowledgeable and as skilled at imparting knowledge. Thank you.
We all do. Teachers are busy spreading socialism and racist propaganda... thats all they do. Thats why our kids cant think or read well or deal with science. No new welders or plumbers or carpenters ... kids are told how racist they are and that the environment is doomed. Yet the leftie leaders have massive houses and fly everywhere. And dont wear masks. Thats for the lowly idiots to do.
They are, but they have a class full of kids and some dweebs choose to be twats and the teacher spends the lesson dealing with the dickheads while you miss out on what they could impart. It’s easy on RUclips, this guy can talk and his audience can’t affect anyone, so you get a one on one. Just think before leaping. Teachers cop it in the neck because the government keeps the idiots at school instead of pissing them off to boot camp or disciplining them.
Thank you for your informative videos, Captain, I absolutely love the B- 737. I’m a US Army Veteran, and a G.A. Pilot, and the nephew of a US Air Force B52 pilot, (and several other pieces of Air Force equipment). I’m very grateful for the knowledge of any instructional videos or face to face aviator knowledge shared with me. Flying has always been my passion since childhood. I’m absolutely a free spirit when I fly alone, and I absorb what I can to fly safe and to always be prepared for any situation. God Bless You, Sir, and thank you for your contribution to aviation.

My uncle was a crewchief during ww11. Army Air Corps. I became an aircraft mechanic for USAFR 1979 to 1985. Im still learning from Mentour.
Mentour = best and most detailed explanation
Captain joe = easy to understand explanation
Mentour I really respect your knowledge of aviation
Yep! I love the depth on this channel. I knew it was the flaps mechanism, but then video of actual motor for the flaps in operation, stuff about FSEU and other flap related systems. Same with the "Why no main gear doors on the 737" video. Simple answer would suffice, but here's all this extra information on it. Top quality content.
I agree, not to diminish Captain Joe- he does a great job- especially with all of his analogies. Mentour Pilot acknowledges everything and always makes sure you know almost everything.
They both target different audiences and both do a good job making videos with their target in mind. Captain Joe targets the general public, while Mentour targets enthusiasts, pilots in training, current pilots, etc.
They are not married, despite what people dont say.
Captain Joe and Dutch Pilot Girl should be, though.
I’m not a tekky person and I don’t understand the basics yet, but I love the mentality of Captain Mentour. Really focussed and well-argued. Gets to the reason why and doesn’t indulge in any kind of exaggeration and pointless window-dressing. I wonder how closely these video explanations replicate the classes the Captain’s lectures gives to his actual trainee pilots?
Oh I’ll bet pretty much the same he commands attention speaks well and when finished your all the better for it.

I've watched those flaps extend on many an airplane coming in to land, I am always amazed by the rigid strength they have as they get buffeted by the air. Now I know why they are so strong.
Yes, they no longer make them from string and sealing wax.

As an electronics engineer myself, though retired, my first job back in 1972 was in aviation. I was doing avionics servicing in general aviation from the smallest planes up to cargo DC-4s and a couple executive jets. One of the reasons I got hired at that as my first job out of school is that I was an aviation groupie.
I knew those pods were the flap actuators but did not know before how they worked. I am sure many will find the tech stuff boring but for me, bring it on. You cannot get too technical with me at least.
There are a lot of homo stewards in that business and I bet you enjoyed yourself and miss it now!
DM Fraser
There are a lot of gay stewards romping after one another in that business and I bet you enjoyed yourself and miss it now!
@@redblade8160 I never worked on aircraft that had flight attendants. The Cargo DC-4 flew supplies to a uranium ore mine in the middle of nowhere and brought back tightly sealed barrels of uranium ore.
It was general aviation work. Where I was dispatched to planes around an industrial airport and never met the flight crews or plane owners.
So your assumption of getting involved with gay stewards is an entirely unjustified assumption.
@@dmfraser1444
You said you were a Groupie, well that is a person(s) who enjoys various forms of sex with medical personnel in the Air Medical field.
I was a little bit nervous about flying. I knew deep down inside that pilots very well knowledgeable however turbulences, take off and landing still put me on the edge of my seat. Now, after watching your videos about all these, reassure me about flying. Thank you for a job very well done.
Bart Maheu don’t go. You will surely die. Most airliners crash.
I was a Jet Mechanic in the US Navy during the Vietnam War and worked on Pratt&Whitney TF-30 P408 engines. After looking at those photos of the Fearing gear assembly I forgot how much safety wiring we had to do on Jet aircraft engines and any other moving parts on the aircraft. Every nut and bolt and fitting were safety wired to each other to prevent the nuts, bolts and fittings from coming loose in flight.
The real fun was safety wiring the engines combustion cans at the center of the engine. There were always a few combustion cans that were hard to get at and you had to use a mirror to see what you were doin. Thus you were observing a reverse image in the mirror while wiring the combustion can bolts. It was a challenge and took a little practice.
To complete what you said: these trailing edge pods also reduce the wave drag which appears at high speeds. This is why they are so bulky (they could be slimmer if their role was only to cover the flaps mechanism). When this aerodynamic effect was discovered, a few aircraft like the Convair 990 were designed with dedicated "anti-shock bodies" on the trailing edges. Aircraft manufacturers later found it much more efficient to combine them with the flaps fairings.
Shocks begin to form on the upper surface before the bottom. Obviously because the upper surface is where the air accelerates. The lower surface on modern aircraft such as A320 family and forward use the super critical airfoil that incorporates a trailing edge cusp to also mitigate the formation of shock waves. I would be cool if the fairings stayed on the upper surface like the 990. My intuition says that took up wing area on the lifting surface.
Antoine Bonnet
Except,..
That doesn't come in to play here.
Good Explanation of why it would at mach-+.
But these, as in most Boeing "Commercial" Aircraft. Is for ease of removal and maintenance.
And hence their dimensions.
Tolerances at less than Mach, are less critical.
Just a simple explanation from a 49yr Boeing engineer.
@@My-Pal-Hal I thought anti-shock bodies were used to reduce wave drag at transonic flight no? Well within the envelope of the 737.
@@tonybalogna123
But these are just aerodynamic fairings to cover the flap tracks.
And they are only held in place with a single row of screws around the top of the fairing. Which in itself shows they don't normally experience much turbulence,.. normally. And why they were a bit larger than they technically had to be. Again, for ease of maintenance too.
They are there to protect the flap tracks system from dirt and debris. And keep crap out of the gobs of butter lube within.
And those are Technically Called "Torque TUBES",.. not torque rods. You have to be Good at Safety Wiring those, especially on the 747. A torque tube nightmare. Trust me 😬
Those fairings on the 747 were big enough for a 12 person Canoe 😂
... if you screwed them together of course 😊
The 47 was my fav.
And in the old days. If you know what final assembly is.
Final Assembly is were you bring all the aircraft sections together. Body, Wings, Gear, Control Surfaces, Electrical Systems etc. And assembly the complete airframe. Minus most of the interior, engines, paint,.. that sort of thing.
Anyway.
We were assembling a 747 every 3 days, with no travelers (100%) for almost 3yrs. Till the cycle changed again. We were building them faster than they knew what to do with them 😂
Good Times. We had fun 🤗
Which reminds me of a term few people have ever heard. "Crease Backup". You get a ⭐ if you can find that one.
...other than this comment 😏✌️
@@My-Pal-Hal Love the explanation. Not gonna lie, the "anti-shock" explanation does sound a little sexier and exciting than just an ol' safety cover for the flap mechanism... but I've asked a few engineers now, and they all pretty much say the same thing you're saying.
Modern airliner engineering is a marvel. The engineering behind the passenger experience is unbelievable. Thanks for taking the time to explain to us all of these aircraft features. Your channel is great man keep it up!

I was sleeping and suddenly heard this
Speaking of landings... (sorry, but this might be a bit off-topic, but I was hoping you might be able to steer me in the right direction nonetheless...)
I was a passenger on a plane in May of 1998 that had a near-miss with another airliner, at LaGuardia. I am talking about a big airliner, landing on runway 22, coming within 20 feet or so of another that was departing on runway 31. We went over the departing plane, as our pilot abruptly pulled up and gunned the engines, calmly announcing that we were going to go around to take a little sight-seeing tour of downtown Manhattan, which we did do (aside: our view of the WTC led me to imagine what a terrorist might be able to do to the WTC if he had a plane this close -- as close as we were -- to it).
I realize this was some time ago, but it was such a significant event that I cannot get it off my mind. Since I did find a very similar (but not exactly the same) occurrence that also happened at LaGuardia, within the same timeframe (Friday, April 3rd), I thought that this might have been it, but it isn't happen at the right time (it was at least four weeks, and perhaps as much as six weeks earlier).
I know the date of the near-miss that FAA has on its website (Friday, April 3rd, 1998) and I know the date of the event that I was attending, the '98 SAME Conference (Society of American Military Engineers) in midtown Manhattan (19th-20th May). From memory, I believe that I took the flight from St. Louis Lambert to LaGuardia
I have found another event that was very similar in the FAA logs, but it just was different in a few specifics, and possibly off on the date by several weeks... I have reason to doubt this was the one, but still think it probably was just yet another near-miss at LaGuardia.
Apparently, this incident was never reported or recorded. I didn't report it. That's what's interesting to me, there were so many people involved, pilots, tower controllers, passengers, and the incident so potentially horrific, it surprises me that there is no documentation of it. Any way to remedy this, at this late date? Or, specifically, to find out if there might not be some record of it, after all, in FAA ledgers? Thanks.

Yes, the technical aspects of aircrafts is gaining information that I refer to as a puzzle to be filled in with each piece of the puzzle. In this video in addition to seeing what these pods do, and the approach used to solve problems that can happen. I also realized why some fans addressed the question if the aircraft could be armed? It does have that appearance if one knows they are there. Continue doing what you do you do it very well as your fans have so often written. You do space the technical with incidents that happen that is also a source of knowledge that blends our learning and interest.
In 1971 the track roller bearings on the 737 wing were causing problems. They would lock up, shear the cotter pin holding the retaining nut, unscrew the nut and leave the bearing lying in the nacelle you see on the cover picture. There was a bulletin on the 737 to re lubricate the track roller bearings every 50 hours. I was a Sales Engineer working for McGill Bearings who manufactured aircraft bearings. Boeing was my customer. Larry Blakley, structural engineer assigned to the 737 wing asked me to become involved in the problem. The application and problems were similar to fish cleaning machines in Alaska (manufactured in Seattle by one of my customers) which had been solved by my efforts With support from McGill engineering dept, I proposed a solution. Last I heard, the test aircraft at United had flown 7 years without lubrication or failure. I believe my effort contributed to the success or the 737 aircraft. This scenario would not happen today because the mechanism has been replaced by computer software.
Did I get rich, no, I was doing my job. McGill Bearing made a bunch of money!

Lol not so much when you realize how many moving parts are on a jet airliner and statistically the more moving parts you have the higher risk of failure you have.

These pods under the wing are the trailing edge anti-shock bodies used on the Handley Page Victor bomber, commonly referred to as "Küchemann carrots" invented by Dietrich Küchemann, who worked for the Royal Aircraft Establishment. They greatly reduce drag. Kuchemann is also credited with the Coke-Bottle 'area rule'.
You're 100% right. This isn't really covered in the video, but the reason the pods are where they are, and they are the shape they are, is due to the Transonic Area rule (as the Coke-Bottle rule is properly called).
Most 3rd year Engineering students learn how to derive this rule when studying supersonic flow. Basically, supersonic flow can "choke" when "turned" too much by a rapid change in body geometry. From this concept, the ideal "cigar" body can be derived.
This is more obvious in some planes like the DH Comet, where some of these concepts were implemented for the first time.
the flap track farings in slang are often called "canoes" due to their appearance. the forces involved by such actuators is quite significant and the reason why such are "pinned" during maintenance operations to avoid potential fatal accidental actuation during maintenance operations (such pins being treated as surgical instruments during medial operations and carefully accounted for so as to prevent being left behind before aircraft is put back into service)
I was on a flight where one of these “pods” was loose. When the flaps were down the pod shaked wildly. When the flaps were up the pod was hanging down but not shaking. We landed ok but it scared a lot of the passengers.
yeah it can be scary but even if one of those breaks loose there would be nothing to worry about :D
Yet again the author is full of shit. Pods wouldn't create "enormous amount of drag". The most important parameter when calculating drag is the area measured from the direction of air. When packing in something you increase the area, thus the drag.
@@friedchicken1
"Nothing to worry about", what about hitting someone's head on the ground or smashing through a roof?
@@redblade8160 oh yeah
@@RUclips_Stole_My_Handle_Too You misheard him, rewatch it and turn subtitles on starting at 1:30. He says "the pods are there to *streamline* the air as it's flowing through" and "IF the pods *were NOT* there, it would cause an enormous amount of drag." Literally says the pods decrease the drag. The trailing flaps cause the drag, not the pods. The pods support the flaps and decrease drag, as well as help make sure the flaps are extended equally to create even lift/drag on both wings.

2:07 I thought the flaps, in addition to those things, were also supposed to increase the stall AOA by allowing a small amount of the higher pressure air underneath the wing to blead through the gaps between the flap and the main wing in order to prevent flow separation during landing, when a higher AOA is needed due to the lower airspeed?

Suuuure you are....
Yes, continue to produce videos.
I fly a lot. I'm amazed at how LITTLE the average human knows about what even makes a plane fly. Most people don't know how ANYTHING works. I think people should at least take a small interest in how basic things work in life. Nice job explaining this.
I like the variety of topics. I look forward to every new video. Thanks.
Yes please, more technical everyday airplane stuff.
Det här är bra skit!
Very perceptive answers,,for years I,ve been pondering over those pods, and no doubt I,d continued if not for you putting yourself as the pilot into the curios shoes of your patrons,,thanks 👍
Glad I could help!
I really like what you're doing, it's very interesting and listening to you it's very well explained on all systems. Great job! Keep them going!
Brilliant as always!!! ✈️🛫
Thanks!
The US Military plane was a US Navy P-8 Poseidon, they are modified Boeing 737-800ERX’s that are designed for ASW (Anti-submarine Warfare). They carry torpedoes, harpoon anti-ship missiles, and depth charges.
keith moore Guess I did
And chemtrail chemicals too! Let's not forget to dump chemicals on them nasty snubmarines!🤮
+Reese McClain - And the P8 is also operated (with slight variations) by the Indian Navy and the Australian Air Force. It has been ordered by the Royal Air Force and the Royal Norwegian Air Force. The latter has mighty good reasons for submarine interdiction.
Yep that’s the item and capability index for one of it’s primary missions sets.
keith moore sensors win wars. You’re in the right path.
Wow, I’ve always wanted to know this myself, as I fly frequently. Passenger jets are a wonder of technology, but I’ve always been fascinated by just the design, thought, and engineering that goes to just the wings structure alone.
i love how this guy answers all the questions about planes we had when we were little
Thank you for the clear explanation. Keep it up.
Great thanks from morocco....i always travel and i really appreciate all the usefull details given.
Wow. Below is my comment from 8 months ago. Now I am a huge fan of Mentour Pilot and I wouldn't write a comment like that. Even If all this video could be answered with a single sentence ("These are flaps extension mechanisms.") for me 8 months ago, now I like the fact of extending the insight into the mechanisms. And I don't mind a little bit of slow paced overexplanations from my current favorite RUclipsr.
I was a passanger once when flaps malfunctioned and we landed with a bit more speed. You have great videos on tech that has always interested me but the stuff I never botherd to look for and understand better. :) Getting just enough deeper into the rabbit hole from my current base knowledge. Thanks yt for offering these after searching basic stuff on airplane and helicopter flying :)
Very good simplification of different systems of an aircraft.
Thank you! My goal is for everybody to understand my explanations.
8:50 It's a big deal if the runway is very short, f.ex like in Funchal Madeira. It is extended but back in 1979, it was kind of dangerous. I remember we stood waiting for the plane while the pilots did some rounds back and forth before, we were allowed on board. The pilots tried to find the right speed without passengers, so they better knew how fast they had to go with passengers. It was a Boeing 727.
Extremely interesting content. Thanks so much Captain!
