Hi guys, just thought I’d put something out there. :) I got my hands on a performance calculator for the Dash-8 Q400, to get accurate readouts of V1, VR, V2, VFRI, VCLIMB and takeoff torque %. If you want those I can calulate them for you, just comment these specs:
– Airport ICAO code
– Departure runway
– Flap settings (should be flap 5 or 15)
– Surface wind
– OAT (Outside Air Temperature)
– Takeoff weight
For example, comment something like this: “ENGM, 01L, flaps 5, 350/12, 6 degrees, 1016, 2924kgs”
To elaborate on the speeds:
The speed beyond which the takeoff should no longer be aborted.
Takeoff safety speed. The speed at which the aircraft may safely be climbed with one engine inoperative.
Flap Retraction Initiation. The speed you have to be above before retracting flaps (Q400’s often just go straight from flap 15 to flap 0, no need to go via the other ones)
Max performance / recommended climb speed
