on take off how do you get the word take off to be said so you know when to take off?
not on flight sim unless someone has got a link for a program to download!
in real life the non flying pilot at the time ( ie 1st officer or the one not holding the cow horns ) will call out the speeds V2=takeoff safety speed. Also called takeoff screen speed, the minimum speed in the second segment of a climb following an engine failure.
critical engine failure recognition speed. V1 is the minimum speed in the takeoff, following a failure of the critical engine at VEF, at which the pilot can continue the takeoff with only the remaining engines. Any problems after V1 are treated as inflight emergencies. In the case of a balanced field takeoff, V1 is the maximum speed in the takeoff at which the pilot must take the first action (e.g., apply brakes, reduce thrust, deploy speed brakes) to stop the airplane within the accelerate-stop distance and the minimum speed at which the takeoff can be continued and achieve the required height above the takeoff surface within the takeoff distance. In this context, V1 is the takeoff decision speed.
here check this:-
And for clarity's sake, the the correct order is of course V1 - Vr - V2
correct, very late night post!
