DescriptionSecondary Stalls are caused by attempting to rush the completion of a stall recovery before the airplane has regained adequate flying speed or before sufficiently reducing the angle of attack.
ObjectiveDemonstrate the effects of improper control usage on stall recovery.
Procedure• Complete pre-maneuver checklist. Clear the area. Make radio calls as appropriate. Maintain 2300 RPM and approximately 90 KIAS.• Perform a stall. Perform a power-off or power-on stall to a full break.• Improper recovery. Initiate normal stall recovery by simultaneously relaxing back pressure, adding full power, turning carb heat off and holding wings level while maintaining coordination.•Induce secondary stall. Immediately increase back pressure to increase pitch attitude and angle of attack to induce a secondary stall to a full break.• Recovery. Simultaneously relax back pressure, add full power, turn carb heat off and hold wings level while maintaining coordination. Accelerate and climb out at or as specified.
ACS Standards• The applicant demonstrates the ability to identify, assess and mitigate risks, encompassing: secondary stalls, accelerated stalls, cross-control stalls.
