The Airbus A330 stall recovery in place...
The fundamental misunderstanding is, that this is
not the stall recovery procedure, but the procedure to be applied when the stall warning starts to sound. It actually is a stall prevention procedure in case you get close to stall. And as such, it works perfect.
Large aeroplanes are not intended to be stalled, hence there is no procedure required to recover from a fully developed stall.
