Quick note: at 3:26 I mention that turboprops fly slower than jet aircraft. This is generally true, but I could have demonstrated it better by comparing True Air Speed (TAS) instead of Indicated Air Speed (IAS) as I did in the video. Comparing IAS is not a good idea since it is not your actual speed through the air, and it's also dependent on altitude. Long story short: since jet aircraft fly higher, this helps them in actually flying faster (even though IAS may give the impression you're flying slower). Thanks!
8:24 Thanks Max, Great video about de Havillands latest VSTOL the elegant Q400. The Q400 is one of my favourite aircraft as well, and describing the plane as beautiful is no exaggeration. Like the other de Havilland greats, the Beaver, the Otter, and the Mosquito, the Q400 has a holistic design which creates an all-around resonance. You point out that it is this feature of mutual design integrity which brings all the praise. I would love to hear about the Q400’s excellent safety record, its innovative noise-dampening system, and its ice management system. Lastly, doesn't this de Havilland deserve a better animal name?
Good comparison, but you keep saying "much slower" than jets. This is true generally for many turboprops, but for the Saab 2000 and Q400, they fly at "near jet" speeds hence can be slotted into shorter routes with similar sector times to jets. The Q400 is just over 100 knots faster that the Dash 8-300. I love all of them. On the 737, we typically descend at 280 knots indicated, whereas on the Q400, it sometimes was 270-280. So its not your average slow turboprop.
you should have lived through the story. My dad started working in DHC back in 1962. and I was there when the Dash 8 series 100 rolled out... the people that were there, were awesome. they would talk to you about the next IMPROVEMENT. a bigger or longer dash 8. I saw the first take-off of all 5 versions. and it is sad to see them go
The Q400 is my favourite plane. I fly it with WestJet on most flights I take. One thing I've always found amazing about the Q400 is just how fast it is for a propeller-driven/turboprop aircraft. Its cruise speed of 667 km/h (414 mp/h), while slower than jets, is faster than the majority of propeller-driven/turboprop aircraft. The Q400 is a very common sight at my airport, Fort St John Regional Airport CYXJ. They are also very common in Canada, WestJet has 47 Q400's and Air Canada has 44 Q400's.
Yes, sometimes I get the q400 around BC or with flights to Alberta, all around good plane, short takeoff run and when they land you can feel when they reverse the prop pitch from pull to Push 😊 , 1 hour flights are just fine in these planes 🎉
First time on a Q400 was with Porter. Flying out of Billy Bishop. Sometimes I'll head down to the waterfront and just watch the Q400's land and take off from Billy Bishop.
Definitely a reason why the Q400 is superior in some aspects to e.g. the ATRs. But it also comes with a cost, since it is said to have the complexity of a jet with the speeds of a turboprop... Also super fast for a turboprop is/was the Saab 2000. Not built anymore, never a great commercial success (only 63 built), but definitely a beautiful plane, and she had a slightly higher speed than the Q400 but 6 years earlier.
Really awesome! Love how the physics gets visualized in X-Plane 11! Have been really enjoying the Q4XP a lot these days! Definitely feel free to build a series on the Q400 design!
Max, as you may know, hor-stabs are airfoils that are "flipped upside down" which create "lift" in the opposite direction, when sufficient airflow is flowing over and under it. Therefore what you'll have is a plane that tends to pitch up not down. Since you mentioned the Twin Otter... I suggest you google am image of it again and look at where the hor-stabs are positioned on it... they are right in the flow of thrust generated by the props.
My son-in-law is a captain for one of our local airlines flying the Q400. Also I have always loved being a passenger on the Dash 8 so I would love to learn more about them.
Just completed a r/t Portland, OR/Vancouver BC with AirCanada on Dash 8'S. BEST AIR TRIP I HAVE HAD IN YEARS!!! It was actually fun to fly. Great plane. Quiet and comfortable. Sat in row 9 so got to watch the prop outside my window.
Correction - The horizontal stabilizer provides downforce for stability not lift - Additional airflow from the propellers causes the nose to pitch up - Not down.
My first air-experience was in Bombardier Q400. U travelled with my family from Delhi to Dehradun. It usually takes 6 hrs from Bus and on this plane it was under 40 minutes.
Hi Max, nice work. I love the simplicity of the Dash-8, especially in the cabin - no fancy computer screens to interrupt casual conversation with fellow passengers. Ahh, what air travel used to be like.
Would love a more in-depth description on the aspect ratio, aerodynamics of different wing designs beyond the basics and from an Aero Engineer's perspective.
Hi Max. Superb video. I'm a bumbling X-Plane user, but I'm interested in the details of airplanes and flight, and your explanation was outstanding: clear, concise and informative. The flight sim community really benefits from videos of this quality. Like others, I feel you deserve a huge subscriber base, so I'll join the team. Thanks very much!
I can't overstate how grateful I am for this comment. I always thought the internet was an unforgiving and harsh place, but because of people like you this couldn't be further from the truth. It's almost overwhelming, and inspires me beyond you can imagine. I'm going to try and pay your kindness forward both online and offline. Thank you Damon.
@@FlyByMax You're welcome. My compliments and appreciation are genuine. YT comments are much too often miserable, so for all us us, making the effort to be kind is important. The good human thing to do!
I am a frequent flyer on 400 Air Canada Express. Only problem what we run into quite often the lock of the luggage room. Sometimes the grand crew having difficult time to be able to fit all of the luggages and yes, we need to double the plane with a second 400, efficiency is gone. Other then that this little "Deery" is so much fun to fly and so cute! Yes, as you mentioned the braking power of the props reversing flow is amazing! Winter time on slippery runways is much much safer than the runners brake! Love this bird! ❤
I agree with the other comments to develop an entire series to discuss the various aspects of the Q400 design. That would be awesome. You do a wonderful job of explaining the subject matter. Great work!!!!!!
Im taking a QANTAS Dash 8 400 from Brisbane to Longreach tommorrow. I loved the F27 Friendship, which was much loved here in Australia. However, i think the Dash 8 is a great replecement for the Friendship. It has proved itself well.
Canberra to Sydney block times for Q400 are the same as 737/320 jets. Result of distance and shorter runway at Sydney allowing for Q400, lack of congestion and angle of runway, it points to Canberra. The Q400 lands basically when arrives with no competition for the runway. The jets have a longer route and competition for runway.
Im doing my ATPL's rn and my instructor flew a dash 8 for flybe, great plane, my other instructors were pilots for the hercules, phatoms, 747s, 737s but theres somthing so great about the dash 8's
Yes, please make a series. When the video was over I felt like I had watched the intro to a video and now the main content would begin. Please continue, this is so interesting :-)
The reason the Dash 7 has 4 props has almost nothing to do with noise. Like Dehaviland Canadas previous designs, the Caribou, Buffalo, Twin Otter, etc; the Dash-7 was designed and optimized for STOL performance. 4 engines were used because existing turbo prop engines of the day were either insufficient powerful or too large for 2 of them to generate the required maximum power for take off.
An absolutely superb explanatory video. Clear, concise and highly professional. I would be delighted if you would continue to expand and develop the series. Top marks !
Another good perk of the T tail is when i was towing them into the hanger it made it very easy to stack more planes over eachother. The anvs system gave this plane a lot of issues though as if you lost 4 or more attenuators from thd anvs system the system would become in-op. The problem with that is the propeller balancing system drew its data from the anvs system. There was 42 throughout the cabin and you would lose about one a day so it was a constant battle that inflated the maintenance cost. Another daily issue was the integrated blade cuff suffered wuite a lot off differential shrinkage at temps below 40F which lead to a large number of trailing edge cracks which either needed to be patched of replaced nightly. These blades also suttered from water ingress quite badly from those cracks which would lead to bubbles of water near the tip that would freeze and delaminate, this was also fixable but it was a very time consuming repair. The last issue with the blades was that was a phenolic liner under the blade pitch bering race in the hub side, which would rip often and sling grease all over the place. The greases would also cause the rubber for tge deice boots to soften so they would fatigue faster. The landing gear was all right but you had to be strong enough to climb upleg to gain access to all the hydraulic equipment above usually laying on top of the down-lock. Interrogating the EMU was interesting as it was bassed on the analogue interface from the origonal -8 to communicate faults. Bassically you would maintnance discrete switch on the engineers panel and the torque and rpm gauges would move to a position which corresponded to a fault and you as a mechanic had to know what guage fault was what.
In high school my shop teacher told us that before he retired from dehaviland he worked as an engineer responsible for the landing gear design for the dash 8. I didn’t appreciate this at the time. His name was Mr Fraser, I don’t remember his first name. Really smart guy.
Thank you for the video max! Yes please make a series, I'm interested in learning whatever it is you can share. it is just a cool to know thing for me. Appreciate the video bro!
Small correction but if the horizontal stabilizer is behind the downwash if would cause it to generate more down force, not lift, since the airfoil shape is cambered upwards, so it would pitch nose up not nose down.
You made a mistake at 5:27. You showed the horizontal stabiliser to create lift and raise the tail section, but in fact, the center of gravity is usually located in front of the center of pressure. The C of G pulls down, while the centre of pressure acts upwards as in lift (wings). This means that the horizontal stabilizer on the empennage section is mounted in such a manner as to put a downward pressure on the tail section, not up.
The point being made was that if the horizontal stabilizer was flush with the engines, the high speed air pushed backwards from the engines would pass over the horizontal stabilizers and the stabilizers themselves would create extra lift. The extra lift at the far rear of the aircraft would force the tail up and the nose down. Think of it as the center of pressure being moved further rearward causing the tail to lift.
@@jond3929 that’s the point, the horizontal stabilizer is an airfoil that is mounted upside down on most airplanes so that airflow creates a downward force on the tail, not upwards. So increase airflow would increase downwards pressure.
I've flown on these all over Canada and often wondered about the details you are talking about. Thanks for teaching me about this and I'd love to watch subsiquent episodes
I absolutely loved the Dash-8 series. I flew in the old 100 series in Alaska and in the Q-400 in the Mountain West. Its sad to see them go into retirement.
One thing that has always amazed me is how such seemingly small, thin wings manage to keep such a long fuselage aloft. I live in southwestern Ontario, Canada, and there is an airport in my city which handles a lot of commuter/short-haul flights. As a result, Q400 aircraft are quite a common sight.
Great video ! We can feel a certain admiration of this aircraft in your voice that made your video again more interesting ! You deal with original topics it’s nice, I learnt a lot on the design choices of this Dash 8 I would be interested to see your playlist on aerodynamics :) Just a remark, 3:28 maybe you should not have compared IAS for cruise speed because of the 10K feet differences, GS (and even TAS) would have been much more relevant to see how really big is the cruise speed difference between a turboprop and a turboreactor
Thank you :)) your remark is absolutely correct, and you're completely right, that would have made an even stronger point about the differences between the two. Thanks for teaching me something as well!
Asian Spirit a small airline in the Philippines has Dash 8 and used in short runways of the old airport such as Caticlan as its a STOL. Now Q400 NextGen was used by Philippine Airlines.
This made me miss flying the Q4XP in XP11. Truly one of the best (if not the best) turboprop sim out there. A close tie with the Hotstart TBM tbh. Great vid!
I absolutely love the dash 8, and was super excited to see this video! I would love to learn more about this beautiful aircraft if you were willing to put in the time to make that series! Thank you so much for sharing this insight! 🙂 Best of luck with the channel! Subbed!
What a wonderful comment, thank you for taking the time out to write such kind words. I'm currently working on the next one, and people like you make more of a difference than you could ever imagine. Wish you all the best. -Max
Great video and since its 2 years old i kinda was looking forward to watching some more of your dash 8 content. Unfortunately i saw your last video was a year ago. I hope you are doing well.
Informative, excellent detail and superb graphics. Yes, would love more - such as flaps and slat operations, landing gear and that bit about cabin pressure levels prior to opening hatches after landing. 👍
I would really enjoy being a passenger in the Q400 if the seats weren't so cramped (in the Air Canada layout). They are very narrow and there is not enough legroom. If the seating were better, then it would be a lot of fun. Those props give it a really quick take-off, the low altitude and high wings make for great views on a clear day, even the wing seats get a good view once the bird is in the air. But the cramped seating makes it a miserable experience for a tall-ish guy like me, especially with some of the long routes that it gets used for in Canada.
I worked with both the -7 and 8. I always found the 7 the more fascinating. Seeing it's STOL capabilities was really pretty spectacular! Alas it was slow and more expensive to run.
Great video, Max - and this is my favorite airliner to fly in Xplane - I spend pretty much my whole time on VATSIM in this plane (and the rest in the Twin Comanche for GA).
25 years ago, almost half the flights at Seatac Airport were turboprops, typically Dash series. Their landing appearance was like bugs with dangling legs. Those days are long gone. 😊
I would define like to learn more about the various aircraft components such as the ailerons, flaps & why the horizontal stab is mounted high on the tail as opposed to the standard fuselage mounts Thank you for sharing.
I believe the main reason for the elevated horizontal stabilizer is the aggressive, stylish statement it makes. I liken it to ending a sentence with an exclamation mark, rather than a period. Why do I believe this? Because I choose to! Great Video, Thanks!
Very interesting details... I've been thining of getting this regional airliner, since I have no turboprop aircrafts. This coould be truly a game changer for me... Thanks for the info. 🙂
Hi, Can you please explain why Dash Q 400 features a significantly large horizontal tail (16.7 sq. m with much bigger volume coefficient of ~1.7 ) compared to ATR 72 (11.7 sq. m with volume coefficient of ~1.1)?
Flown on one twice, very powerful on take off, around 1500 ships horse power each engine, ,think in the late eighties jersey European used to fly them from Birmingham to Majorca, great plane.
If I had a time machine I would love to sit on one of those flights. Loads of Ozzy Osbourne types that have filled their luggage with the food they eat at home normally 😂
I took the Dash 8-400 for the first time with Air-Canada from Bathurst N-B to Montreal Qc. It was a 90 minutes flight, the flight it self went pretty good. The only complaint I have it the seat are thight.
Yep as some pointed out horizontal stabilizer's lift is angled downards not upwards. This allows a greater margin in where the center of gravity of the aircraft can be (forward of the wings). Why then, not angle both wing's and stabs' lift upwards, and have the center of gravity aft of the wings? Think of the landing gear config...
It's an absolutely brilliant plane. A bit of a handful to fly in turbulence or to land smoothly, but that makes it more interesting & satisfying, too. And let's not forget, it is massively over-powered! In other than tropical air, it will hit VMO with an engine out!
Dash 7 & 8 would be awesome…air Tindi is the largest single operator of the rare type now. I was fortunate to ride in one back in the mid 80s on a flight to Penticton from YVR. Certainly the aircraft wasn’t breaking a sweat on that flight, but I am glad to say I have been on it. The Quad Otter.
How about a video as an introduction to DeHavilland Canada ( DHC)? You could introduce each of their models, i.e.,DHC-1, DHC-2, etc. Most of DHC’s line-up are focused on short field/utility/“bush” operations. They are a real Canadian success story! By the way, great video on the Q 400. Apparently the Q-400 is being used in air-tanker roles (water bombers) here in Northern Alberta, Canada. I haven’t looked into it’s capabilities in this role (another idea for a video!)
I like your analysis but i just want to correct one thing. The horizontal stab provides lift but in the opposite direction. The lift vector is downward rather than upward.
I was on a turboprop once already, but I'm still looking for a chance to flying a Dash 8. Way back I got a hop in an RCAF Buffalo. But I'm thinking it was different somehow. My Grandfather flew a De Havilland Mosquito in the war. He was killed on ops in 1943. My dad liked to tell a tory about the time he saw a De Havilland Beaver take off in the _width_ of the runway and then coming around over the airfield, throttling back and actually move backwards relative to onlookers. It was obviously a very windy day.
Excellent video although I think you meant "horizontal stabiliser" at 5:28" rather than vertical stabiliser aka the tail fin. Do please do that video on the Dash 7 - a fascinating aircraft.
4:53 You definitely need stairs or a belt loader to load the Q400. Unlike the earlier Dash-8s, the Q400 sits nose down tail up, and thus the baggage compartment sits quite far off the ground.
Great video. I fly in the Q400 regularly and I'm interested in the Q designation. I assume they play the engine noise 180 degrees out of phase to cancel the noise, but my, it is a noisy aircraft. Especially when taxiing when there is a mid range whirring/growling sound on some of them.
You’re correct - Q designation means it’s equipped with the Active Noise/Vibration Suppression System (ANVS). However the vibration of a turboprop takes their toll on the sensors of the system and often the system is unserviceable or operating in a degraded mode.
Quick note: at 3:26 I mention that turboprops fly slower than jet aircraft. This is generally true, but I could have demonstrated it better by comparing True Air Speed (TAS) instead of Indicated Air Speed (IAS) as I did in the video. Comparing IAS is not a good idea since it is not your actual speed through the air, and it's also dependent on altitude.

6 miles a minute EASILY vs 9 ... N O T that slow
Who told you that bs about the Dash 7 using 4 engines to reduce noise? It uses 4 engines to be powerful. It's an STOL aircraft
Good comparison, but you keep saying "much slower" than jets. This is true generally for many turboprops, but for the Saab 2000 and Q400, they fly at "near jet" speeds hence can be slotted into shorter routes with similar sector times to jets.

The Dash 8 can do loop-the-loops, barrel rolls, stall climbs, steep bank turns, and high speed dives.
great. as if I wasn't already nervous to fly and always get put on a dash 8
It those maneuvers weren't a part of a tragedy, I would have definitely put those facts in my marketing scheme

Beautifully condensed, Mac...More strength to you, in your future videos, to enhance the learning and comprehension of ppl who wish to learn👍
Thank you!
You made a mistake at 5:27. You showed the horizontal stabiliser to create lift and raise the tail section, but in fact, the center of gravity is usually located in front of the center of pressure. The C of G pulls down, while the centre of pressure acts upwards as in lift (wings). This means that the horizontal stabilizer on the empennage section is mounted in such a manner as to put a downward pressure on the tail section, not up.
The point being made was that if the horizontal stabilizer was flush with the engines, the high speed air pushed backwards from the engines would pass over the horizontal stabilizers and the stabilizers themselves would create extra lift. The extra lift at the far rear of the aircraft would force the tail up and the nose down. Think of it as the center of pressure being moved further rearward causing the tail to lift.
@@jond3929 that’s the point, the horizontal stabilizer is an airfoil that is mounted upside down on most airplanes so that airflow creates a downward force on the tail, not upwards. So increase airflow would increase downwards pressure.
@@jond3929 Horizontal stabilizers make lift DOWNWARD. It would push the nose up, not down. That's simple aerodynamics.
I've flown on these all over Canada and often wondered about the details you are talking about. Thanks for teaching me about this and I'd love to watch subsiquent episodes
The kind of video I didn't knew I needed until it started... Thank you!
Love flying in this aircraft, always a pleasure.
I would definitely watch and surely enjoy a series on the Dash 8
Nice to see EBAW in your video, this is where i do my flight training
Wat zijn de kansen :) when I was recording I thought I had some scenery for it!
@@FlyByMax Are you Belgian by any chance? I see a lot of Brussels airlines and EBBR in your video's
@@beau4690 I am!
@@FlyByMax very nice, i definetly couldn't tell by your accent, you sound so english.
Anyways keep up the good work!
@@beau4690 I'm half-half, but my English is a little bit better than my Dutch (Vlaams), thanks!
I absolutely loved the Dash-8 series. I flew in the old 100 series in Alaska and in the Q-400 in the Mountain West. Its sad to see them go into retirement.
Love the dash 8. Such a unique aircraft. Would love to see a whole series on the flying pencil!
Love Dash8 . A series would be incredible.
Thank you Max, such awesome content mate. I would live to learn more, please keep up the great work 👍
Thanks so much!
One thing that has always amazed me is how such seemingly small, thin wings manage to keep such a long fuselage aloft. I live in southwestern Ontario, Canada, and there is an airport in my city which handles a lot of commuter/short-haul flights. As a result, Q400 aircraft are quite a common sight.
Great work Max and thank you for your efforts at educating us
The fact this does a barrelroll is amazing. The skyking brought me here!
Great video, deserves more views
Thank you so much!
"Flight simulation is about learning". Finally someone said it! Thank you 🙂
Thanks!
Excellent explanation of an amazing airplane. Yes, please, if possible, do a series on it, These aircraft deserve to be better understood.
Kindly continue with the Q400 series, awaiting more of your content
Great video ! We can feel a certain admiration of this aircraft in your voice that made your video again more interesting ! You deal with original topics it’s nice, I learnt a lot on the design choices of this Dash 8
I would be interested to see your playlist on aerodynamics :)
Just a remark,
3:28 maybe you should not have compared IAS for cruise speed because of the 10K feet differences, GS (and even TAS) would have been much more relevant to see how really big is the cruise speed difference between a turboprop and a turboreactor
Thank you :)) your remark is absolutely correct, and you're completely right, that would have made an even stronger point about the differences between the two. Thanks for teaching me something as well!
Asian Spirit a small airline in the Philippines has Dash 8 and used in short runways of the old airport such as Caticlan as its a STOL. Now Q400 NextGen was used by Philippine Airlines.
I love flying on the Dash 8 and always try to get a window seat near the wing just to watch the undercarriage in action!
Love to learn more about the Dash 8.
Great breakdown on the design of the Dash 8. You should definitely explore different aircraft in the same way.
This made me miss flying the Q4XP in XP11. Truly one of the best (if not the best) turboprop sim out there. A close tie with the Hotstart TBM tbh. Great vid!
I absolutely love the dash 8, and was super excited to see this video! I would love to learn more about this beautiful aircraft if you were willing to put in the time to make that series! Thank you so much for sharing this insight! 🙂 Best of luck with the channel! Subbed!
What a wonderful comment, thank you for taking the time out to write such kind words. I'm currently working on the next one, and people like you make more of a difference than you could ever imagine. Wish you all the best. -Max
Love the video. Very concise and understandable.
Great video and since its 2 years old i kinda was looking forward to watching some more of your dash 8 content. Unfortunately i saw your last video was a year ago.
I hope you are doing well.
Hi! Thanks for your comment. As it happens, I'm working on something big right now that should be published by the end of next month. Cheers :)
@@FlyByMax good to hear and can't wait!
Hi, new video is out :) ruclips.net/video/pfTdJD2OakA/видео.html
Informative, excellent detail and superb graphics. Yes, would love more - such as flaps and slat operations, landing gear and that bit about cabin pressure levels prior to opening hatches after landing. 👍
I would really enjoy being a passenger in the Q400 if the seats weren't so cramped (in the Air Canada layout). They are very narrow and there is not enough legroom. If the seating were better, then it would be a lot of fun. Those props give it a really quick take-off, the low altitude and high wings make for great views on a clear day, even the wing seats get a good view once the bird is in the air. But the cramped seating makes it a miserable experience for a tall-ish guy like me, especially with some of the long routes that it gets used for in Canada.
I worked with both the -7 and 8. I always found the 7 the more fascinating. Seeing it's STOL capabilities was really pretty spectacular! Alas it was slow and more expensive to run.
Great video, Max - and this is my favorite airliner to fly in Xplane - I spend pretty much my whole time on VATSIM in this plane (and the rest in the Twin Comanche for GA).
25 years ago, almost half the flights at Seatac Airport were turboprops, typically Dash series. Their landing appearance was like bugs with dangling legs. Those days are long gone. 😊
I would define like to learn more about the various aircraft components such as the ailerons, flaps & why the horizontal stab is mounted high on the tail as opposed to the standard fuselage mounts
Thank you for sharing.
I believe the main reason for the elevated horizontal stabilizer is the aggressive, stylish statement it makes. I liken it to ending a sentence with an exclamation mark, rather than a period. Why do I believe this? Because I choose to! Great Video, Thanks!
Tank you very much for all informations :)
Thanks max, I enjoyed your way of presenting and explaining 👍
Nice detail! Would like to see more!
Neatest thing about the Q400 is the implementation of NVH mitigation in the body of the aircraft to minimize prop noise.
great movie. concise but clear descriptions and detailed animation.
Thank you!
Very interesting details... I've been thining of getting this regional airliner, since I have no turboprop aircrafts. This coould be truly a game changer for me... Thanks for the info. 🙂
Yes me too. I couldn’t decide between a dash 8 and an E-bike…still can’t decide
Great video max put would love more about dash 8
I love the view of the landing gear
The Skyking brought me here
RIP Skyking!
Me too. Rip. He sounded like a nice guy 🥹
Hi, Can you please explain why Dash Q 400 features a significantly large horizontal tail (16.7 sq. m with much bigger volume coefficient of ~1.7 ) compared to ATR 72 (11.7 sq. m with volume coefficient of ~1.1)?
Flown on one twice, very powerful on take off, around 1500 ships horse power each engine, ,think in the late eighties jersey European used to fly them from Birmingham to Majorca, great plane.
If I had a time machine I would love to sit on one of those flights. Loads of Ozzy Osbourne types that have filled their luggage with the food they eat at home normally 😂
@@psions555 😀
5000 hp each
I took the Dash 8-400 for the first time with Air-Canada from Bathurst N-B to Montreal Qc. It was a 90 minutes flight, the flight it self went pretty good. The only complaint I have it the seat are thight.
Not sure if you have done additional videos on the DHC-8 but I would be very interested to see more!
Yep as some pointed out horizontal stabilizer's lift is angled downards not upwards. This allows a greater margin in where the center of gravity of the aircraft can be (forward of the wings). Why then, not angle both wing's and stabs' lift upwards, and have the center of gravity aft of the wings? Think of the landing gear config...
Excellent video / explanation... thank you!
I love this video, really informative and interesting. The Q4XP is definitely my favourite aircraft just so much more refreshing than the 737 or A320
Thanks!
Does anyone know what type of plane is shown @0:10 ... left hand side photo? ... thanks in advance
Saab 2000
About to take off in a q400 in a few minutes :)
It's an absolutely brilliant plane. A bit of a handful to fly in turbulence or to land smoothly, but that makes it more interesting & satisfying, too. And let's not forget, it is massively over-powered! In other than tropical air, it will hit VMO with an engine out!
Dash 7 & 8 would be awesome…air Tindi is the largest single operator of the rare type now. I was fortunate to ride in one back in the mid 80s on a flight to Penticton from YVR. Certainly the aircraft wasn’t breaking a sweat on that flight, but I am glad to say I have been on it. The Quad Otter.
How about a video as an introduction to DeHavilland Canada ( DHC)? You could introduce each of their models, i.e.,DHC-1, DHC-2, etc. Most of DHC’s line-up are focused on short field/utility/“bush” operations. They are a real Canadian success story! By the way, great video on the Q 400. Apparently the Q-400 is being used in air-tanker roles (water bombers) here in Northern Alberta, Canada. I haven’t looked into it’s capabilities in this role (another idea for a video!)
Please make another part this was amazing
I like your analysis but i just want to correct one thing. The horizontal stab provides lift but in the opposite direction. The lift vector is downward rather than upward.
Nice explanation, what a great aircraft capable of many things !
This is interesting, I'd like to see more!
Because of a couple of crashes on landing in Copenhagen, the plane is sometimes called the Crash-8 here in Denmark 🇩🇰
Max i thank you too for this lesson about q400
I was on a turboprop once already, but I'm still looking for a chance to flying a Dash 8. Way back I got a hop in an RCAF Buffalo. But I'm thinking it was different somehow. My Grandfather flew a De Havilland Mosquito in the war. He was killed on ops in 1943. My dad liked to tell a tory about the time he saw a De Havilland Beaver take off in the _width_ of the runway and then coming around over the airfield, throttling back and actually move backwards relative to onlookers. It was obviously a very windy day.
Excellent video although I think you meant "horizontal stabiliser" at 5:28" rather than vertical stabiliser aka the tail fin. Do please do that video on the Dash 7 - a fascinating aircraft.
4:53 You definitely need stairs or a belt loader to load the Q400. Unlike the earlier Dash-8s, the Q400 sits nose down tail up, and thus the baggage compartment sits quite far off the ground.
Awesome video Max!!
Great video. I fly in the Q400 regularly and I'm interested in the Q designation. I assume they play the engine noise 180 degrees out of phase to cancel the noise, but my, it is a noisy aircraft. Especially when taxiing when there is a mid range whirring/growling sound on some of them.
You’re correct - Q designation means it’s equipped with the Active Noise/Vibration Suppression System (ANVS). However the vibration of a turboprop takes their toll on the sensors of the system and often the system is unserviceable or operating in a degraded mode.
Well done Max!
