G'day O_S
wasn’t the worry about Vs that if derived from the performance stalling manoeuvre then the load factor i.e. ratio of lift to weight could be significantly less than unity. In which case the multiplying factor would give illusory rather than desired margins. So the Vsr technique could be said to give “proper” V2 speeds rather than “lower”. [1-g stall speed as the basis for compliance… refers]
Otherwise very nice reply I have no trouble with. How’s it going?
