[New] Bombardier Dash 8 Q400 Aircraft Guide

INTRO:
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.

The following is 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 :)

BOMBARDIER DASH 8 Q400 AIRCRAFT GUIDE


GENERAL INFO & LIMITATIONS

GENERAL INFO

~ 2 Pratt & Whitney PW150A engines that together produce over 10,000HP
~ Service ceiling of FL250 although FL270 may be used
~ Speed of 350Ktas
~ 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 Q400 does not have autothrottle, so I do recommend flying it without speed mode on the autopilot. (Although I suggest you engage it while away from your device during cruise)

LIMITATIONS

Flap 5: Max 200kts
Flap 10: Max 181kts
Flap 15: Max 172kts
Flap 35: Max 158kts
Maximum Landing Gear Operating: Max 200kts


STARTUP AND TAXI

STARTUP AND TAXI

~ 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
~ Spoilers will be armed before takeoff and will remain armed until after landing


TAKEOFF DATA

TAKEOFF DATA

Note: Initial climb speed = V2 + 15 and covers flap retraction speed

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

100% 133 / 151 124 / 141 120 / 136

T/O POWER SETTINGS

  1. 90% Power for normal operations (Normal Takeoff Power [NTOP])
  2. 100% Power for maximum performance (Maximum Takeoff Power [MTOP])

TAKEOFF PROFILE

TAKEOFF PROFILE

~ Arm Spoilers
~ Advance power smoothly to takeoff power
~ At Vr, slowly pitch to 5 degrees till airborne
~ Increase pitch to maintain initial climb speed (or greater!)
Note: Do not exceed 15 degrees of pitch
~ At 1000AAE, slowly pitch for 5 to 10 degrees to accelerate
~ Patiently select Flaps 0
~ Patiently set climb power (75%)
Note: Max 200kts below 3000’ AGL
~ At 3000’ AGL, transition to roughly 5 degrees pitch to continue acceleration
~ Maintain 245kts
~ At 10,000’, Adjust V/S to maintain desired climb pitch/profile (High speed climb or low speed climb as desired) (3-5 degrees pitch recommended)


CRUISE

CRUISE

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

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

DESCENT

DESCENT

~ Use the standard 2 degree VNAV profile
~ Power such that IAS = Vmo minus 5


LANDING DATA

LANDING DATA

Format: Approach speed

Load Flap 15 Flap 35
12% 115 101
30% 117 103
47% 123 108
64% 129 113
82% 134 118
100% 139 123

LANDING PROFILE

LANDING PROFILE

~ 20nm from touchdown or on downwind - Slow to 210kts
~ 15nm from touchdown or on base - Slow to 190kts
~ Within 10nm from touchdown - 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 150kts
~ At 150kts - Select Flap 35 (if required) - Slow to Vapp
Vapp Flap 15 = Vref+10
Vapp Flap 35 = Vref

LANDING TECHNIQUE:
~ 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 your questions and suggestions below! :)

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.

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

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

True

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?
