A maneuver the Airbus flight system performs is Escape from CFIT. I do not recall the part, if any, Stall Warn played...
If CFiT is imminent, in Normal Law, The stick can be pulled .back to to the stop, throttles to TOGA, and if a turn is needed, the stick moved to the stop either right or left.
The aircraft will fly on the edge of STALL, at maximum bank, and climb, turn at max allowable as determined by the a/c, not the pilot. It nibbles at STALL, and the a/c Escapes, or not, depending on the proximity of the obstacle.
It is an emergency maneuver, and since PJ2 was involved in the discussion, I take it to be accurate, as I can remember it...
I am assuming Approach to STALL can be taught in similar manner, (or confused with it), but I am unclear what effect the Warning has on the performance, or the LAW. I think this was one of the drills Asseline was going to perform. The a/C cannot suss obstacles, and at the time had issues with sequencing inputs when RA and wow became operant....my assumption is that the a/c, if healthy, can be flown at any AoA short of Stall, and will simply sink if thrust is not increased. Seems like a pretty impressive system...theoretically, I think, had there been no trees, the 320 would have sunk onto the runway, had there been one, or if throttle had been advanced sooner, the aC would have performed as advertised.
Please take this at face value, it is from memory, and may contain errors.
