Isn't it rather a DOWNWARD wind that would explain pitch = aoa at horizontal flight they had at FL380? Should be about 10 kts for 185 kts airspeed and 3 deg chord angle. Could the down draft also explain the compensating NU sidestick pilot's input, which in turn sent them (without alpha protections and reliable airspeed info) to FL380 with loss of airspeed and finally to a stall?

t54 its pitch attitude and angle of attack being 16 degrees
its geometrie: in still air if the flightpath = chord angle (mayby + 3 deg....) than pitch attitude= AoA
Yeah, I got that; but the flight path is horizontal at the top of the path.
You could only get pitch = AoA in horizontal flight if there is an upward wind.
Maybe there was and that's what helped to get the plane up there in the first place.
