Accelerated stalls are accomplished at an altitude that allows completion no lower than
3,000' AGL. Transition smoothly from cruise attitude to a bank angle of 45°, maintaining
coordinated turning flight, while increasing elevator back pressure steadily to induce an
impending stall.
1. Perform two 90° clearing turns
2. Clean configuration flow
3. Slow to 80 KIAS
4. Slowly reduce power to idle
5. Establish a coordinated 45° bank turn
6. Maintain altitude to induce an impending stall
7. Recover at the first indication of an impending stall (e.g., aircraft buffet,
stall horn, etc.)
8. Reduce AOA, level wings, and set max power
