In-Flight Maneuvers • 45
GROUND USE ONLY
CFI Secondary Stall (Power-On)
Secondary Stalls are to be accomplished above 3,000' AGL. The purpose is to
demonstrate the eect of attempting to hasten the completion of a stall recovery before
the airplane has regained sucient ying speed. Demonstrate and simultaneously
explain secondary stalls from an instructional standpoint.
1. Perform two 90° clearing turns
2. 1500 RPM (maintain altitude)
3. Clean conguration ow
4. At 60 KIAS, simultaneously increase pitch (slowly) and apply full power
5. Increase pitch attitude to induce stall
6. At stall, recover – simultaneously reduce AOA, max power, and level
wings
7. When stall horn silences, increase pitch to induce a secondary stall
8. At stall, recover – simultaneously reduce AOA, max power, and level
wings
