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.
Elements:
- Aerodynamics related to power-off stalls and what occurs as a result of uncoordinated flight. Emphasis shall be placed upon recognition of the stall and recovery.
- Relationship of various factors such as landing gear and flap configuration, weight, center of gravity, load factor, and bank angle to stall speed.
- Flight situations where unintentional power-off stalls may occur.
- Selects an entry altitude that will allow the task to be completed no lower than 1,500 feet AGL or the recommended altitude, whichever is higher.
- Performance of power-off stalls in descending flight (straight or turning).
- Transition smoothly from a stable approach to a landing attitude and hold attitude until stall occurs.
- Maintain coordinated flight to prevent the possibility of a spin.
- Recognize and announce the first aerodynamic indications of the oncoming stall, i.e., buffeting or decay of control effectiveness.
- Recover promptly after a stall occurs by simultaneously decreasing pitch attitude, applying power, and leveling the wings to return to a straight-and-level flight attitude with a minimum loss of altitude appropriate for the airplane.
- Maintain a specified heading, ±10°, if in straight flight; maintains a specified angle of bank not to exceed 20°, +0/-10°, if in turning flight, while inducing the stall.
- Retract the flaps to the recommended setting; retract the landing gear, if retractable, after a positive rate of climb is established; accelerate to Vy before the final flap retraction; return to the altitude, heading, and airspeed specified by the instructor.
Common Errors:
- Failure to establish the specified landing gear and flap configuration prior to entry.
- Improper pitch, heading, and bank control during straight ahead stalls.
- Improper pitch and bank control during turning stalls.
- Rough or uncoordinated control technique.
- Failure to recognize the first indications of a stall.
- Failure to achieve a stall.
- Improper torque correction.
- Poor stall recognition and delayed recovery.
- Excessive altitude loss or excessive airspeed during recovery.
- Secondary stall during recovery.

How this relates to a full-stall landing
This maneuver is also known as a approach to landing stall.
