Power-On Stalls
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with power-on stalls. Note: See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.
Bottom line
A power-on approach to stall is trained and checked to simulate problematic takeoff scenarios. A power-on approach to stall may be performed from straight-and-level flight or from shallow and medium banked turns (up to 20 degrees of bank). When the airplane reaches the stall warning, the recovery is made first by reducing the AOA until the stall warning is eliminated.
