Safetypee in particular, that's brilliant - you I definitely owe a (real!) beer to
So in a nutshell, the LDR is reduced by the difference between 50ft/3° and 35ft/5.5°, which is always going to be 180m, near as dammit - since so far as I can tell there's going to be no change to braking effectiveness.
For the 33° flaps T/O, presumably the increased flap setting reduces Vs slightly and thus Vr and V2, giving a slightly shorter TORR and slightly steeper initial climbout segment? Does anybody have any numbers for the effects of this that I might be able to play with?
