AFH Chapter 4-14 Fundamentals of Stall Recovery - 2

 

4. Add thrust/power. Power should be added as needed, as stalls can occur at high power or low power settings, or at high airspeeds or low airspeeds. 

 

Advance the throttle promptly, but smoothly, as needed while using rudder and elevator controls to stop any yawing motion and prevent any undesirable pitching motion. 

 

Adding power typically reduces the loss of altitude during a stall recovery, but it does not eliminate a stall. 

 

The reduction in AOA is imperative. 

 

For propeller-driven airplanes, power application increases the airflow around the wing, assisting in stall recovery.

 

5. Retract speedbrakes/spoilers (if equipped). 

 

This will improve lift and the stall margin.

 

6. Return to the desired flightpath. 

 

Apply smooth and coordinated flight control movements to return the airplane to the desired flightpath being careful to avoid a secondary stall. 

 

The pilot should, however, be situationally aware of the proximity to terrain during the recovery and take the necessary flight control action to avoid contact with it.

 

The above procedure can be adapted for the type of aircraft flown. 

 

For example, a single-engine training airplane without an autopilot would likely only use four of the six steps.

 

 The first step is not needed therefore reduction of the AOA until the stall warning is eliminated is first. 

 

Use of pitch trim is less of a concern because most pilots can overpower the trim in these airplanes and any mistrim can be corrected when returning to the desired flightpath. 

 

The next step is rolling the wings level followed by the addition of power as needed all while maintaining coordinated flight. 

 

The airplane is not equipped with speedbrakes or spoilers therefore this step can be skipped and the recovery will conclude with returning to the desired flightpath.

 

Similarly, a glider pilot does not have an autopilot therefore the first step is the reduction of AOA until the stall warning is eliminated. 

 

The pilot would then roll wings level while maintaining coordinated flight. 

 

There is no power to add therefore this step would not apply. 

 

Retracting speedbrakes or spoilers would be the next step for a glider pilot followed by returning to the desired flightpath.
