V2 and obstacle clearance
To all the performance gurus,
Can anyone explain in simple terms the effect of changing V2 on the performance especially with regard to after takeoff obstacle clearance?
If V2 cannot be less than 1.2Vs (or 1.1vmca) then surely it is a function of configuration and weight.
So, if we increase the weight (all other factors constant) we increase the V2 speed but what happens to our 1st, 2nd, 3rd obstacle clearance performance?
If we use more flap our stall speed reduces so our V2 would be less? What does this do to the climb gradients?
