Accelerated Stalls
To determine the applicant understands accelerated stalls (power-on and power-off), can apply that knowledge, manage associated risks, demonstrate appropriate skills, and provide effective instruction. Note: See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.
Bottom line
An accelerated approach to stall should be performed with a bank of approximately 45 degrees. The pilot should select an entry altitude that allows completion of the maneuver no lower than 3,000 feet AGL.
