About stall and AoA
Some reflections to invite comment:
- An airplane stalls when it exceeds a critical angle of attack, regardless of airspeed.
- Stall warning is an important protection against stalling, especially when airspeed is unreliable.
- Pilots should be able to rely on stall warning and should respect it when it occurs.
- Stall warning should be based on angle of attack and should not be corrupted by false airspeed information.
- If there is a need for an additional warning based on airspeed to cater for unreliable AoA, that warning should say something like "SPEED SPEED SPEED" rather than "STALL STALL STALL".
That being said, a stall is normally not catastrophic as long as there is sufficient height available to recover from it. 35000 ft should normally be sufficient.
