PJ2, your last post was interesting ... but it disappeared (?)

Without the F/O sidestick readout, the actual load factor demanded and achieved, it is impossible to be certain why the elevator is in that position. Hope that's clearer.

I read you 5/5
TP, and that's why I do ask the BEA :
Where is the load factor graph ???
From time 15 45 57 the elevators were in the amazing full down position when the Capt (We don't know for the FO ...) was actually pulling on its side stick.
As the speed was building up, I suspect the elevators were just trying to counteract the increasing effect of the inappropriate THS position, and so in order to respect the load factor limitation ...
