[New] Bombardier Dash 8 Q400 Aircraft Guide

Hey everyone, Cody here and I’m a real world Q400 pilot looking to shed some light on the Q400 we have here in Infinite Flight. I tried as best I could to keep it as simple and digestable as possible but any criticism is welcome as I plan to update this information as necessary.

Although our model may be outdated, it really does behave mostly like the real thing just with a little bit of modification based on the physics and systems we have available to us. The following is just how I’ve applied real world experience to the model we have here in IF and it is simply here as a tool to enhance your experience. That being said, this information is obviously completely unofficial, and it certainly does not cover the full complexities of the actual aircraft so do only take this for what it’s worth :)

General info


~ 2 Pratt & Whitney PW150A engines that together produce over 10,000HP
~ Service ceiling of FL250 although FL270 may be used
~ Speed of 360Ktas
~ Max seating capacity of 78
~ Range of 1100nm

A few notes:
~ I left trim out of the equation as it doesn’t have much complexity in the real thing and I find it to be a subjective value here in IF because it depends on how you have your device calibrated (as well as personal preference)
~ The spoilers should be armed before takeoff, and remain armed throughout the flight, until taxi in
~ The Q400 does not have autothrottle, so I do recommend flying it without speed mode on the autopilot. (Although I might suggest you engage it during cruise so your speed doesn’t creep into the red while you’re mowing the lawn)
~ Landing basically requires no input… land with power on and let ground effect do all the work
~ Start the #2 engine at the gate before push. And start #1 before taxi or before departure
~ Single engine taxi procedures are conducted with the #2 engine
~ Power setting in % means throttle position

Takeoff & Climb


Flap 5: Use for any normal takeoff
Flap 10: Use for additional performance
Flap 15: Bush plane mode


Note: Initial climb speed: V2 + 15 and is above Vfri
Format: Rotate / Initial Climb Speed

Load Flap 5 Flap 10 Flap 15
12% 108 / 124 104 / 120 100 / 115
30% 108 / 128 104 / 120 100 / 116
47% 113 / 134 104 / 125 101 / 121
64% 121 / 140 111 / 131 108 / 126
82% 126 / 145 117 / 132 114 / 131
100% 133 / 151 124 / 141 120 / 136


90% PWR for normal ops (Normal Takeoff Power [NTOP])
100% PWR for max performance (Max Takeoff Power [MTOP])
83-89% Low density alt/long runways (Reduced Takeoff Power [RTOP])
Use caution when operating with reduced power and high load


Note: Avoid climb rates of less than 1000’/min
Note: Pitch as required to continue acceleration
~ Advance PWR smoothly to takeoff power
~ At Vr, pitch for 5 degrees till airborne
~ Continue to pitch nose up to maintain initial climb speed to 1000AAE (max 15 degrees)
~ At 1000AAE, pitch for 5 to 10 degrees as required to accelerate
~ Ensure accelerating and select Flaps 0
~ At 175kt, set clb pwr of 75% and continue to accelerate
Note: Max 200 below 3000’ AGL
~ At 3000’ AGL pitch for 4 degrees and continue to accelerate
Note Max 245 below 8000’
~ At 10,000’, Maintain 4 degrees pitch at 75% PWR to cruise altitude

The key here is to get the airspeed up because the performance significantly improves as you get closer to 240kts

Cruise & Descent


~ Reduce PWR from 75% to a power setting that maintains:

  1. Vmo minus 5 or…
  2. Flight planned cruise speed


~ Normally a 2 - 3 degree slop is used so the VNAV profile is reccomended
~ PWR such that IAS = Vmo minus 5

Approach & Landing


Flap 15: Vapp=Vref+10 (Flap 15 recommended)
Flap 35: Vapp=Vref. (Flap 35 for shorter landing dist and slower approach speeds)


Note: Obtain Vapp by 500’ AGL
~ Flap 35: Vapp=Vref.
~ Flap 15: Vapp=Vref+10
Format: Vref

Load Flap 15 Flap 35
12% 105 101
30% 107 103
47% 113 108
64% 119 113
82% 124 118
100% 129 123


~ 20nm from touchdown - Slow to 190Kts
~ At 190kts - Select Flap 5 - Target 180kts
~ At 180kts - Select gear down - Target 170kts
~ At 170kts - Select Flap 10 - Target 160kts
~ At 160kts - Select Flap 15* - Target 140kts
~ At 140kts - Select Flap 35 (if required) - Slow to Vapp
(Flp 15: Vref+10 // Flp 35: Vref)
~ Land with power on, little to no flare required
~ Max 5 degrees nose up at touchdown
~ Reverse not required, only as desired

Being our only turboprop airliner, the Q400 is unique and its capabilities are worth enjoying. It’s super easy to fly in Infinite Flight and can get you in and out of some incredibly special places so I hope it can find a place in your logbook :)

Please leave you questions and suggestions below! :)


nice one, hope this will help me complete my aircraft butter landing list

Thank you for this! Bookmarked!


You are very welcome!

Thanks! I should fly the Q400 more…

Yes, yes!

Just had my first-ever realistic DH8D flight. Never have I learned something about the procedures of this aircraft before! Thanks for this informative tutorial.


Spectacular job on this guide. Definitely gonna make use of it whenever I use the Dash 8

Glad it worked out! 👍👍

Thanks for this great tutorial! I used to fly it a lot in IF until Alaska Horizon retired it 😭 I am happy I did get to go on Alaska q 400 before it retired. Also what airline do you fly the q400 for

Awesome! Yeah absolutely a bit of a shame but what can you do :/ Won’t share but I appreciate the comment :) Cheers!

There are only like 3 Q 400 operators in Canada, so take a guess :)

i tried this and nearly crashed, did i do something wrong?

Just make sure you are always accelerating so pitch the nose down if need be


Also all power settings mentioned are not N1. It’s just throttle position

Hi Cody. Thanks for this. Very helpful. Mark Denton did Dash-8 takeoff and landing tutorials for Infinite Flight’s YouTube channel 7 years ago. There are some differences between his tutorials and your info here. For example, you recommend landing at 140kts with the power on, set to roughly 40% or greater. Mark recommends final approach of 110-115kts, landing at 100-105kts. That’s quite a difference in speed and technique. There are several other differences. Not sure what to do.

Hey! I think these are the landing speeds given by Cody, relative to the load on board. 140 kts just the speed you should be at when deploying the last set of flaps.


Yes, I think you are right. Those numbers in the Flap 15 and Flap 35 columns must be kts, and the greater the load, the greater the speed, from 105kts up to 129kts fully loaded. Makes sense. My dumb.


Question: Does this need to be adjusted for wind direction and speed, like on, for example the 787-9, where 1/2 of the headwind component + full gust (max 10kts) is added to the Vref to obtain the Vapp speed?
