Term
Power-on stall recovery techniques
Definition
Reduce AOA

Smoothly advance PCL to Max

Apply coordinated rudder and aileron to level wings

Recover with minimum altitude loss without encountering a secondary stall (15.5-18 AOA)
Term
A power on stall maneuver is complete when
Definition
positive climb is establsihed
Term
The two key objectives of traffic pattern stalls
Definition
Develop recognition of potential stall situations that occur in the traffic pattern

Develop skills and confidence in recovering from developing low altitude stalls with minimum altitude loss
Term
Procedures for entering a break stall
Definition
Set up simulated initial and adjust power to maintain 200 knots

Retard the PCL to approx. 10% torque and roll into a 60 degree bank turn

Midway through the turn, increase bank and back stick pressure until a stall indication is recognized.
Term
Recovery from a break stall
Definition
Reduce back pressure and rapidly roll the wings level with coordinated rudder and aileron. Do not loose altitude during the recovery.
Term
Overshooting (nose low) final turn stall entry procedures
Definition
Configure aircraft for simulated final turn (120 KIAS, Gear down, flaps landing, TO or UP)

Initiate normal final turn

After turn is established, steadily increase bank, backpressure and retard the PCL to IDLE.

Continue the turn until you recognize an approach to stall indication.
Term
Recovery from a over-shoot (nose low) final turn stall
Definition
1.) Reduce backpressure to recover AOA (15.5-18 AOA)

2.) Advance PCL to MAX

3.) Use coordinated rudder and ailerons to level wings

4.) Minimize altitude loss
Term
Entry procedures for an undershooting (nose-high) final turn stall
Definition
1.) Establish aircraft in a landing config at level flight and 120 KIAS

2.) Begin normal final turn

3.) After the turn is established, raise the nose slightly, shallow out the bank and retard the PCL to idle

4.) Continue to turn until you recognize an approach to stall indication.
Term
Recovery from an undershooting (nose-high) final turn stall
Definition
1.) reduce back pressure to recover AOA (15.5-18 AOA)

2.) Advance PCL to MAX

3.) Use coordinated rudder and ailerons to level the wings

4.) Minimize the altitude loss
Term
Recovery from an undershooting (nose-high) final turn stall
Definition
