Power-off (Approach) Stalls
OBJECTIVE: To develop the pilot’s ability to recognize an approaching stall by sound, sight, and feel; familiarize the pilot with the conditions that produce power-off stalls; and to develop the habit of taking prompt preventative or corrective action to recover from a stall.
THINGS TO REMEMBER
Power-off Stall Procedure
- Clearing Turns.
- Execute pre-landing checklist, hold the flaps for now.
- Choose a visual reference on the horizon; point it out and align the aircraft with it.
- Reduce power (or, in complex aircraft, extend landing gear).
- Pitch and trim for 0 VSI, hands off.
- First notch of flaps (relieves back pressure).
- As speed decreases, flaps 2 to relieve back pressure.
- As speed decreases, flaps 3 to relieve back pressure.
- Continue backpressure at zero rate of climb until ASI reaches 1.2 Vso.
- Power to idle (rudder for 0 rate of turn).
- Pitch and trim for hands off at 500 fpm descent.
- Slowly pitch up towards the stall; usually just to or very slightly above the horizon will do.
- Hold the pitch attitude with steadily increasing backpressure.
- Announce the stall buffet.
- Continue increasing backpressure until either wing drop or nose drop.
- Recover with simultaneous release of backpressure, advance throttle to full, and step on the right rudder to maintain 0 rate of turn.
- Pitch down until the stall horn silences, then pitch up to climb, at edge of stall horn activation.
- At positive rate of climb, retract flaps to manufacturer’s recommended
- Pitch to a known go-around attitude; adjust to maintain recommended speed. Climb over obstacles at the recommended speed.
- Clear of obstacles, increase airspeed by pitching down slightly, but not so much as to cause negative rate of climb. Retract flaps in stages. Attain Vy prior to final flap retraction!!!
- Resume normal climb
