Lateral stability in a stall
My experience at and beyond stall AOA in swept wing jets (trying to hold the nose up in a low speed scissors) was that centering the stick laterally and using gentle rudder inputs had the best effect in keeping the wings level. But even then the wings rocked a lot and it needed bigger and bigger rudder inputs to pick the low wing up.
I'm wondering if all those spoilers on the A330 wing more than counterbalance the adverse effect of the ailerons and make it practical to reverse the roll using the stick, particularly once well past the stall AOA? Or is it just the rudder effects from the BYDU and pedal inputs that rolled AF447 back the other way.
