Secondary Stall
(Power-On)
Secondary Stalls are to be accomplished above 3,000' AGL. The purpose is to
demonstrate the effect of attempting to hasten the completion of a stall recovery before
the airplane has regained sufficient flying speed. Demonstrate and simultaneously
explain secondary stalls from an instructional standpoint.
1. Perform two 90° clearing turns
2. 1500 RPM (maintain altitude)
3. Clean configuration flow
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
9. “Cruise Checklist”

1. Perform two 90° clearing turns

3. Landing configuration flow
4. Stabilized descent at 66 KIAS
5. Throttle idle (slowly)
6. Maintain altitude to induce stall
7. At stall, recover – simultaneously reduce AOA and level wings (do not
add power)
8. When stall horn silences, increase pitch to induce a secondary stall
9. At stall, recover – simultaneously reduce AOA, max power, and level
wings
10. Slowly retract flaps to 10˚
11. Accelerate to 64 KIAS (V
X
), positive rate
12. Retract flaps to 0˚
