Stall characteristics as they relate to airplane design, and recognition impending stall and full stall indications using sight, sound, or feel.
Bottom line
An impending stall occurs when the angle of attack causes a stall warning but has not yet reached the critical angle of attack. A full stall occurs when the critical angle of attack is exceeded. It is possible to exceed the critical angle of attack at any airspeed, at any attitude, and at any power setting.
