- The Bombardier Dash 8 Q400's design is what allows it to do such an amazing job in the skies. In this video we go over why the aircraft uses turboprop engines, why the horizontal tail is situated where it is, and the geometry of the landing gear + wings in X-Plane 11.

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?
Unless you are flying in the russian bear!
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
A whole series on the dash 8 would be incredible!
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
yes;
Holy crap. I'm in your video! At 1:36 the pilot in the right seat is me! I flew the Dash 7 for six and a half years. Great plane! Built like a tank.
Congrats bro!
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!
Thank you! Glad you're enjoying Q4XP :)
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.
My first Q400 flight was on a WestJet, a beautiful and powerful turboprop plane. 👍
@@Tjetz777 So Beautiful
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 🎉
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.
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.
Keep doing such vids am really happy how u explained
The fact this does a barrelroll is amazing. The skyking brought me here!
I'm profoundly happy I found this channel. Honestly not even sure you could improve on this -- bravo!
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.
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!
No idea how this vid popped up on my recommended but I'm glad it did! Subscribed, keep up the good work!
This means a lot, thanks for your kind words :)
Loved the vid! Great stuff, keep up the good work! I love seeing new aviation content creators pop up
Thanks a lot!
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
This deserves 50k subscribers at a bare minimum.
Thank you!
@@FlyByMax Yes sir, please keep the content coming. We'll spread the word!
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!
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!!!!!!
Thank you!!
Correction - The horizontal stabilizer provides downforce for stability not lift - Additional airflow from the propellers causes the nose to pitch up - Not down.
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. 👍
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!
Thanks a lot! I've got something coming out soon that you may like :) Cheers!
Thank you Max, such awesome content mate. I would live to learn more, please keep up the great work 👍
Thanks so much!
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.
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
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.
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).
I would definitely watch and surely enjoy a series on the Dash 8
Great breakdown on the design of the Dash 8. You should definitely explore different aircraft in the same way.
great movie. concise but clear descriptions and detailed animation.
Thank you!
This particular model seems to have a history of landing gear troubles. I’m interested in seeing an extended series on this plane. Well Done Sir.
Tank you very much for all informations :)
Great video, deserves more views
Thank you so much!
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
Awesome video Max!!
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.
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 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! ❤
youre never scared the propellers will stop turning?
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!
Kindly continue with the Q400 series, awaiting more of your content
I love the view of the landing gear
"Flight simulation is about learning". Finally someone said it! Thank you 🙂
Thanks!
Well done video!!! Thank you
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!
Please do make a series out of this!
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.
Terrific job!
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.
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.
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.
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!
i would love to see more
I'm watching this Aviation Video Topic on The Dash 8-400's The Dash 8 Family of Turboprops which I fly on back in the Day I hoped to fly on There Q400's Turboprops in the near future Awesome Video Man 100%
Amazing channel
comon do it, we want longer more detailed vids. love this channel.
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 😀
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!
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.
This is first airliner and my favorite airliner. I fly Majestic's sim as I don't use X-Plane right now.
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.
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.
Come back loved the video want more!
series would be very cool!
pls cover the phenom 300, the gulfstream 550, and the falcon 8x. all of which are in xp11/12
I love this plane.
I'm watching this dreaming that soon enough Majestic will bring their excellent Dash 8 to MSFS. They've announced the Q400 but also the smaller variants!
Question. Why does the Q400 pitch down when flaps are extending? Flap design / centre of pressure? Or increased downforce on the tail? Or something else?
Late to the game here but great video. I have always thought this was a cool plane. Even more so after this. One question…what are the three little balls on the centre windshield pillar? They are on other aircraft to and I have always been curious.
Thanks! The little balls are to make sure the pilot's seating position is correct (not too high or low, or forward or backward). If I remember correctly, if you are sitting in the right position then two balls align with each other. Cheers!
Hello, is there a way or add-on to tire smoke on landing? Also some aircraft have smoke on start. Any help would be appreciated. Ty.

About to take off in a q400 in a few minutes :)
I love flying on the q 400
I don’t know the gross weight the dash 8 is but an engineering question I have.
Could two turbo charged Allison V 12’s work with this plane?
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)?
Horizontal stabilizers/elevators conventionally push *downwards* to balance and positively stabilize the plane. More airflow means it pushes the tail downwards, which is exceptionally bad in an aircraft that only has a maximum of maybe 8 degrees rotation. Then you risk tail strike.
Edit: You've somewhat confused thickness (thickness-to-chord ratio) and "aspect ratio," too. The designers chose such a thin section to enhance the Dash 8's maximum speed at the cost of low-speed performance. Still, no airliner is really going less than 12% for the ratio. If you look at the root of a 737, it's definitely going to be thicker, because the structural requirements are much higher for that swept wing, but. If you measure it as a ratio of the chord, it's still in the ballpark of 12%. Below that, there's no great drag reduction, but the structural requirements are more challenging as you have less beam strength to work with.
Thank you for your comment.
At 7:36 I specifically define aspect ratio as the wingspan divided by the cord length (as visualised on screen), so I do not see how I have confused it with thickness-to-cord at all.
It is a fact that the Q400 has a higher aspect ratio wing than most jet aircraft. The Dash 8 has an aspect ratio of 12.32, compared to the Boeing 737 which has an aspect ratio of 9.45, Airbus A350 with 9.25, Boeing 777: 9.96... and so on.
Although I deliberately did not go into detail in the video, the reason for this high aspect ratio is due to the speeds that the Dash 8 flies at. High aspect ratio wings create less induced drag relative to low aspect ratio wings with the same wing area. This means they achieve a higher lift/drag ratio at low speeds and are therefore more efficient.
This NASA page explains it very clearly :)
www.grc.nasa.gov/www/k-12/VirtualAero/BottleRocket/airplane/geom.html#:~:text=Aspect%20ratio%20is%20a%20measure,is%20given%20the%20symbol%20AR.
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.
Sheesh series on the dash 8? 😳😳
I would like to learn more about the Dash-8 Landing gears
Why airberlin? Good video.
You should try the majestic dash 8 q400
the Q is my favourite!!! (q for quiet except NVS never works heheh)
I’m a copilot of a q400 and I can say it’s a beast! You have the risk of overspending with 1 engine inop up to 8000 feet😂
I know atr 72 is not the same but it still got some similarities right?
Turbo-prop engine is more fuel efficient than turbo-fan engine on same distance per passenger. I guess, if we ever return to travel like we used to, propfan engines will see their rise and they will solve their noise levels fast (more efficient than turboprops).
Horizontal stabilizer is on top of vertical due to prop wash and it is common for aircrafts with high wins/ engines or engines mounted on vertical stabilizer... Be-200, B727, An225, Tu154, Tu134, Atr42/72...
hey t here, someone can help ? I installed Q4XP on Xplane 11 and I can not turn on/off switches... there is a hand (like the mouse) but when I cli nothing happens... :( thanks a lot
Should’ve redeveloped the q300 series, would’ve had the regional/domestic turboprop market on lock
What about atr?
Is it true that these planes can stop upon landing so quickly that the seatbelts can bruise the passengers?
Are they safe? I'm flying in one for the first time this weekene lol super nervous.
Extremely safe :) enjoy your trip!
@@FlyByMax thank you!
lol ''in one''
Flew to Croatia with one of those, you feel every smallest turbulence and good forbid if there is some stronger wind, acceleration prior to take off is so all of a sudden that is far from pleasant, landing is also very stressful as it decelerates so quickly after the touchdown and is not very stable..maybe it was due to the pilot I don't know, will not complain about the noise as it is a propeller airplane so it is what it is, however I would rather skip it next time if possible
Please do a seres
I love this airplane but the airlines seem to be getting rid of it and switching to pure jets. That may mean the beginning of the end of this aircraft and aircraft like it. I hope not but the writing seems to be on the wall. But it is a very fast turbo prop, so many kudos to the engineers!
Is this thresholds second channel?
No not at all, this is my (Max's) own channel. I also produce videos for Threshold though.
The Skyking brought me here
What makes it amazing is sky king
I feel like the ATR 75 landing gear is the problem
this is making me want to fly the Q400 in msfs hurry Up Majestic ffs arghh
Unfortunately, it just didn’t sell in North America to the same level as the other models.
Actually I didnt liked this airplane, also today on my trip was one landing in Zagreb, and I looked a little bit what for airplane model is, and Your explanation is superb, now i like the plane becuase of its specification,sorry for bad English.. but very goood video and Thanks mister :)
It is neither “amazing” nor “insane,” in my opinion. I’ve flown on them many times, and they are entirely satisfactory.
Comfortable enough flight I found
Why doesn't... SouthWest use this plane?
i never liked then”q400“ marketing name. it was used to hide the fact this was a dash-8 at time turboprops had bad image. the Q is for “Quiet” simce itvjad new prop design and active noise reduction in fuselage to negate vibration from the props. i much prefer “Dash-8-400“ its real name.
