Fundamentals of stall recovery.
Fundamentals of stall recovery.
Bottom line
The essential aerodynamic stall-recovery action in any airplane is to reduce the angle of attack (AOA). When the airplane reaches the stall warning, recovery is accomplished by first reducing the AOA until the stall warning is eliminated. Losing altitude during recovery from a stall is to be expected. Follow the published aircraft-specific procedure; disconnect installed autopilot or wing leveler promptly and maintain directional control throughout recovery.
Key numbers
| Number | What it means |
|---|---|
| Commercial ACS completion: at least 1,500 feet AGL (ASEL/ASES) or 3,000 feet AGL (AMEL/AMES); use higher AFM/POH recommendations | ACS completion altitude |
| PHAK conditional cruise/design-maneuvering-speed recovery example: 2 or 2.5 Gs; use the aircraft’s approved limits | Illustrative load factor |
