I think PF's initial ss back is starting to gel into the 'climb command', once again. Nothing about BEA suggests that is so.
As to Harry Mann's 'wing drop', as far as it may be the result of airmass flow, it may well indicate a very robust 'up elevator'.
Between the first NU and the second STALL WRN. , only Nose Down inputs are mentioned.
Roll excursions are mentioned. The a/c is climbing rapidly, rolling, and losing energy.
At the 'top' of climb, the AoA decreases, (6?), and there are STALL wrns.
Harry. Climbing, unstable in Roll (with corrections), and losing energy, would not the a/c STALL with increasing loss of altitude due loss of energy, regardless of pitch commands? as the a/c loses energy in climb, the AoA is affected as much by arrival at apogee as Pitch, perhaps more?
In a serious updraft, the correct input, (perhaps other than none!) might be Nose Down? Hold Altitude? Lose as little as possible?
BEA report seems to suggest that PF was not reacting to the climb. Too many here seem to assume the PF was "along for the ride".
Again, I think the source of the STALL was timed to the loss of the autopilot and autothrust. If in an uncommanded climb, of course the PF would not advance the Throttles. He would input ND, and BEA have not said he did not.
With the loss of 'g' at the top, TOGA and "back pressure" relief would be correct? Especially if associated with STALL WARN?
