Fundamentals of stall recovery.

ACS element text (the applicant demonstrates understanding of)

Fundamentals of stall recovery.

Bottom line

Stall training should include proper recognition of when the flight condition has transitioned from the prevention phase into the recovery phase, and proper application of the stall recovery procedure. If recovery from a stall is effected by snapping the elevator control forward, negative load factors may be produced. A recovery from a stall made by diving only to cruising or design maneuvering airspeed, with a gradual pull up as soon as the airspeed is safely above stalling, can be effected with a load factor not to exceed 2 or 2.5 Gs.
