mm43 I read the ATHR disconect 2 sec later 2:10:07

in the acceleration we can seperate two different parts IMO, the average value and the short peaks

the average value will corespond to the main movements of the heavy airbus, the shorter peaks shows the turbulent influence

between 2:10:07 and 2:10:17 the average acceleration get up from 1.0 g to 1.3 g (and fall back to 1.0 g in the following 10 sec) I think this is caused to the elevator move to -1.0 deg (the pull by the PF) also the g-protection can play a rule here

but the acceleration peaks in this time ( 0.8 ...1.6.....0.85 .......1.5 g) indices strong up and down drafts

this are followed by changes in AoA ( 4....2.....5....2....6) and the stall-approach-warning worked perfekt ("stall" if AoA>5.8 deg)

but I think that the air flow over a wing even with this higher AoA will not break down so fast, (flow-seperation needs his time)

so the wing with AoA=6 is still not in a stall, but with this speed he create a very strong lift and can create strong momentes

my read is that the turbulences can caused a lot of this first pitch up......
