Thank you both. It may be obvious, I am trying to look at all the inputs, to find something, a clue, as to why: Stall. One needn't remind of the way it looks as a whole. His spike ND looks almost desperate, even angry. So what I seek is an opinion as to why these emphatic ND's? It is in this region of the accident that CRM seems conspicuously absent. If Someone could explain, for instance, why rather than the jerky motions, PF didn't settle on a nudge/ wait format. The aircraft in Pitch cannot move as his stick would, and since the trace of actual Pitch is far smoother than the inputs that command it, why the constant oscillation in stick/hand?
At the least, is it fair to think that the controls and procedures are more reflective of down low, than up high? From the stick trace, the ND inputs seem solitary, again, as if he is angry perhaps at his own over-control? An unfamiliar response from the a.c?
