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 AOA causes a stall warning but has not yet reached the critical AOA; a full stall occurs when the critical AOA is exceeded. It is possible to exceed the critical AOA at any airspeed, at any attitude, and at any power setting. A pilot should learn to recognize an impending stall by sight, sound, and feel.
