Stall and horizontal stabiliser
Back to basics here if you don't mind... a conventional a/c pitches ND at stall because the horizontal stabiliser is still flying.
Some have referred to PF's glider training. In a glider stall even if you hold full back stick, the nose drops and a/c recovers (before stalling again if you continue) because the HS is flying and there is not enough elevator authority (at ~30 kt) to keep the nose up.
Of course the situation under discussion here is vastly different, but can elevator and power together really maintain a NU attitude in the A330 with a stalled wing and a flying HS?
At the extreme AoA eventually reached, wouldn't the HS have also then been stalled?
