[But in that case how did they get 30 deg NU elevator on AF447?]
OG:
A good question.
Maybe under those ambient conditions full SS NU/full NU elevator at 330K comes up 'short' of +2.5G, just as it would come up 'long' of the -1G with full ND elevator.
I don't have the Va numbers handy.
But I agree at first glance it appears that something 'short' of full NU elevator would achieve +2.5 at 330K.
