Thread drift.
One of the issues with AF447 is that the systems logic deselects the stall aural alert off as it is configured such that if the speed is less than (eg) 60* kts then the aircraft must be on the ground. Thus, as it was stalled and with a very low airspeed, the aural alarm did not activate.
However, when he briefly relaxed the back pressure, the speed increased, alert became active and thus the pilot did what was previously keeping that alert quiet...
*I don't know the actual speed, but it's quite low.

I've never been asked for first time pass exams results for any flying job.
