Power-on (Departure) 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-on stalls; and to develop the habit of taking prompt preventative or corrective action to recover from a stall.
THINGS TO REMEMBER
Power-on Stall Procedures
- Clear area.
- Execute pre-landing checklist, hold the flaps and gear for now.
- Choose a visual reference on the horizon; point it out and align the aircraft with it.
- Reduce power to 1800-2000 rpm to reduce airspeed (to 70 KIAS, typical), while maintaining 0 VSI with increasing backpressure.
- Pitch to an attitude that will result in a stall and set power as desired (min 65%).
- Use ailerons to maintain wings level, rudder to maintain 0 rate of turn.
- As airspeed decays, increased backpressure will be required to maintain pitch attitude. Airspeed decay should be not greater than 1 knot/second.
- Announce onset of aerodynamic warning (buffet) (initiate recovery hear for an incipient stall; if not, continue to full stall).
- Continue increasing backpressure until stall occurs.
- Pitch down to or just slightly below the horizon (may require only relaxing some of the back-pressure) while simultaneously adding full power.
- Keep the turn coordinator on zero with rudder pressure (step on the high wing).
- Once the stall horn ceases, begin slowly pitching up towards a Vx climb attitude. Listen for the stall horn; if it comes on, back off a little on the backpressure. If it stops, increase the backpressure. Continue pitching up at edge of stall horn until reaching the known Vx attitude.
- Climb away at Vx, holding 0 rate of turn with rudder pressure.
- Execute climb checklist.
