For no good reason? Two apparently very brief occurences of stall warning were observed at 02:10:10 and 02:10:13 (page 29 of BEA#3). The reason for those is clearly shown in the traces for normal acceleration on page 42 (Note that normal acceleration is proportional to AoA at a given airspeed). The purple line is the DFDR recording, the blue line is what Airbus has calculated for the pilot's control input without turbulence. At 02:10:10 the pilot pulled slightly over 1.3 g, and a gust increased that to slightly over 1.6 g. Similarly at 02:10:13 the pilot was pulling 1.4 g (increasing towards 1.5 g at 02:10:15), and again a gust increased the pilot commanded 'gee', this time to less than 1.6 g. I would expect the pilot to recognize the 'gusty' origin of the brief warnings, and he should have done nothing except maintain pitch attitude. Whether that is 2.5 or 5 degrees is really of secondary importance.
