FAA Procedures for Power on Stalls

Power-on stalls, also known as departure stalls, are not typical of the kinds of accidents that regularly occur in and around commercial airports. However, given certain negative impacts, they can and do happen. From a dynamic perspective, the result of a straight-ahead departure stall is simple: The airplane stops flying near the ground, even though it's supposed to be operating at a maximum power setting. Given this flight regime, recovery typically nets a negative outcome. However, recoveries have been successfully executed, which is why certified flight instructors make pilots practice the procedure.
  1. Entry Technique

    • Power-on stalls result when an airplane's angle overcomes its available power. To execute the entry procedure, climb to a safe training altitude and establish a standard take-off power setting, then pull back on the controls to create a take off angle. Once this initial angle is established, pull up on the controls again until a stall buffet occurs, followed by a positive stall break.

    Coordination Of Flight Controls

    • To effectively coordinate the flight controls just before, and at the entry of, a power-on stall, you will have to overcome the airplane's tendency to twist left or right due to its high-power setting (called the P-factor). To manage this dynamic effect, you will have to apply contrary left or right pedal input as necessary to maintain straight-ahead flight. While managing this condition, you will also have to control the airplane's tendency to fall off to the left or right due to the wing's stalled condition. To counter this evolution, you will have to apply left or right stick as necessary to maintain even flight.

    Recovery Technique

    • To recover from a fully stalled, power-on condition, you hold the airplane's position straight ahead but without touching the throttle, then monitor the airplane's nose position as it falls below the horizon. Because of the high-power setting, the stall break should not increase beyond a negative 10 to 15 degrees. Then with the nose below the horizon, neutralize the controls, reduce the airplane's power setting, and allow the airplane to pick up speed in the glide until control is regained. Once this occurs, gently pull up on the controls until level flight is again established, then add power as appropriate.
