More about Critical angle of attack
The critical angle depends on wing design and configuration; it is not one universal angle for every aircraft.
Stall speed can change with mass, load factor and high-lift-device settings. Stall recovery follows aircraft procedures and begins with reducing angle of attack rather than simply seeking a particular airspeed.
