Below steps are life Saver at the first indication of a stall ( stick shaker, stick pusher, buffet or aural or visual warning) during any flight phases except at lift off.
🛩Autopilot & autothrottle–Disconnect
Reasoning: While maintaining the attitude of the aircraft, disconnect the autopilot & autothrottle.Manual control is essential to recovery in all situations.
🛩Pitch Control
👉Nose down pitch control–Apply until out of stall (no longer have stall indications).
Reasoning: The priority is reducing the angle of attack.
👉Nose down pitch trim–As needed
Reasoning: If the control column does not provide the needed response, stabilizer trim may be necessary.
🛩Banking–Wings Level
Reasoning: Gentle action sought for recovery to avoid secondary stalls then return to desired flight path.
🛩Thrust–As Needed
Reasoning: During a stall recovery, many times maximum power is not sought.
When stalling, the thrust can be at idle or at high thrust, typically at high altitude.
For Turboprop aircraft, thrust application energizes the air flow around the wing, assisting in stall recovery.
🛩Speed Brakes–Retract
Reasoning: This will improve lift & stall margin.
