I practiced many controlled stalls, and the recovery was just to let the stick go.

There is no stick on Airbus A330, only joysticks:

I have no idea what happens if you disengage the autopilot (already happened in that thunderstorm) and don't touch the joystick. Probably nothing good, considering weather.

I read that at high altitude and speed the A330 is very sensitive to everything, and it is trivial to stall it. Basically you have to have a computer to fly the thing safely because the margin for error is so small.

The stall alert system is also part of the software that flies the aircraft. Nobody can tell what it did; I'm sure the investigation will feed intentionally wrong data into A330's avionics to see what it does. If there is a bug it better be found.

Hey Graysard,

Since the French designed the software that controls the airplane, one could postulate that the software performed just like the French. When things got tough it surrendered leaving the pilots to deal with the situation.... maybe the PFD displayed a white flag instead of a red flag....

Stall warnings were captured on the Cockpit Voice Recorder.
