Hi... I am more or less in agreement with BEA, in fact, I am unwinding their conclusions to include the errant climb, vis a vis the skill/perception quotient.
At one point I was willing to say that the flight path was recoverable perhaps immediately, from the beginning of the descent from apogee. I have seen it done, never in an airliner, which means I am choppless in the discussion.
HazelNuts39.... For purposes of discussion, words like "apogee" and momentum, suggest ballistic influences. Totally Ballistic? It depends, everything is subject to gravity in our environment, BEA suggest the wing has passed its ceiling, just after Power passed its, and. Omentum caused the a/c to continue climbing. Where is the "drastic increase in Drag" Clandestino points up? Certainly not drag from lift exchanges, or do I read BEA incorrectly? The pilot keeps the NOSE UP after limits pass, and starts descending, at virtually identical AoA, so where is the conversion of loss of lift to lowering of the airframe's nose? I suggest that "0" gravity is not possible in any portion of the trajectory, only exceedance and shortfall, so less than "1" suggests ballistic is at work. "Descent" is the result of gravity, always, yes? In any case, My take on the regime around apogee is that the a/c was already Stalled, if your definition is the wings have stopped lifting?
And my conclusion from that is that the pilots were unaware that a Stall had taken place?
One cannot escape the impression forced upon us by the relevant and released data, this crew were not up to UAS recovery in these conditions. That means the discussion should practically revolve around crew, CRM, and flight data issues.
The mechanical/electrical/avionical (?) is there as well, and since there is incomplete data involved for any conclusions, BEA have removed these areas from discussion, IMO. More's the pity, also IMO.
