That depends on how you define "deep stall". From BEA's Update Findings:
- the descent lasted 3 min 30, during which the airplane remained stalled. The angle of attack increased and remained above 35 degrees, (...).
The last recorded values were a pitch attitude of 16.2 degrees nose-up, a roll angle of 5.3 degrees left and a vertical speed of -10,912 ft/min.
For a groundspeed of 107 kt, the last recorded values (assuming no wind) correspond to a flight path angle of 45 degrees down, i.e. an AoA of 61.2 degrees. Deep?
