Excellent post, Ian. Due to the Ecam alerts and warnings, I doubt the PNF was watching what the PF was doing. There was no possible peripheral perception of a yoke moving, unlike non-AB aircraft.
Maybe the A330 shuts off the Stall Warning below 60 kt to reduce the cacophony?
Since the A330 AOA vanes can move to +80 degrees, and the output must indicate actual AOA, why wasn't any AOA greater than +30 degrees (IIRC) enumerated by the BEA?
