A power-off stall is used to develop recognition and recovery skills for stall scenarios associated with approach and landing. The current private-pilot ACS requires an approach or landing configuration, a stabilized descent, recognition of impending-stall cues, a full stall, and prompt recovery using the airplane's POH/AFM procedure.

‍

Safety boundary: Intentional stall practice should be conducted only in an approved airplane, at an appropriate altitude, within limitations, and with qualified instruction. The POH/AFM recovery procedure takes precedence over generic summaries.

‍

The aerodynamic fact that controls every stall recovery

The FAA Airplane Flying Handbook defines a stall by critical angle of attack, not by one airspeed. A wing can exceed critical angle of attack at any airspeed, attitude, or power setting. The handbook therefore identifies reducing angle of attack as the most important recovery action. Power can help reduce altitude loss, but power alone does not remove the stall.

‍

The real situations behind the maneuver

Power-off stall training prepares a pilot to recognize excessive angle of attack in approach-to-landing situations. The FAA specifically connects this training to approach and landing, an improperly flown base-to-final turn, and an attempt to stretch a glide. The common risk is allowing angle of attack or load factor to rise while close to the ground and with limited time to recover.

Operational example: A pilot overshoots the final approach course and tries to tighten the base-to-final turn while also pulling to hold altitude. Bank and load factor increase, airspeed may decay, and the airplane can approach a stall at low altitude. The training objective is to recognize the developing condition, avoid the stall, and use a safer option such as a go-around rather than forcing the turn.

Current FAA Private-Pilot Power-Off Stall Standards

Area
Clear the area before beginning the maneuver.

Minimum Completion Altitude
Complete the maneuver no lower than 1,500 feet AGL in a single-engine airplane or 3,000 feet AGL in a multiengine airplane.

Configuration
Use the approach or landing configuration specified by the evaluator and remain coordinated.

Entry
Establish a stabilized descent, then transition smoothly to a pitch attitude that induces a stall.

Direction
In straight flight, maintain heading within ±10 degrees. In a turn, use no more than 20 degrees of bank and maintain the specified bank within ±10 degrees while inducing the stall.

Recognition
Acknowledge the impending-stall cues, then recover promptly after a full stall occurs.

Recovery
Use the current POH/AFM recovery procedure.

Climb
Configure the airplane as recommended and accelerate to VX or VY, as appropriate.

Completion
Return to the altitude, heading, and airspeed specified by the evaluator.

There is no fixed altitude-loss score

The ACS appendix says stall-recovery evaluation should not require a predetermined altitude-loss value or require the pilot to maintain altitude during recovery. External and internal variables affect the result. The debrief should instead ask whether the pilot recognized the stall, reduced angle of attack promptly, maintained control, used the aircraft procedure, and avoided a secondary stall.

That does not make altitude unimportant. Excessive loss can reveal delayed recognition, an improper sequence, overcontrol, poor energy management, or aircraft/environmental effects. It simply means one universal number is not the FAA standard.

‍

Key deviations to check

The FAA handbook's intentional-stall error list includes failures to clear the area, overreliance on instruments, accelerated entry, delayed recognition, poor coordination, early recovery before the full stall when a full stall is required, failure to reduce angle of attack first, premature wing leveling, power-first recovery, secondary stall, excessive speed, and loss of situational awareness.

1. Entry became accelerated or uncoordinated

Abrupt back pressure or poor rudder use can change the nature of the maneuver and increase spin risk.

2. The pilot waited for the airspeed indicator instead of using all cues

Stall cues can include sight, sound, buffet, control feel, warning devices, and aircraft response. Airspeed is contextual, not the definition of a stall.

3. Recovery began without first reducing angle of attack

The handbook is explicit: reduce angle of attack first. Adding power or trying to level the wings without unloading the wing can prolong or worsen the stalled condition.

4. The pilot tried to preserve altitude at the expense of recovery

Attempting to hold the nose up can delay recovery. The FAA does not prescribe a zero-loss or fixed-loss standard.

5. The recovery produced a secondary stall

An abrupt pull-up before adequate speed and control effectiveness return can exceed critical angle of attack again.

6. The pilot lost heading or allowed yaw to develop

Coordination and yaw control are important to prevent a stall from progressing toward a spin.

What data can help show

Available data may reveal:

• entry altitude and minimum altitude;

• pitch, bank, heading, and vertical-speed changes;

• timing from stall cue/full stall to the beginning of recovery, if event markers are entered accurately;

• whether a wing drop or heading change occurred;

• the shape of the recovery and return to the assigned flight path;

• FlytWERX eIAS trend during entry and recovery, with the active wind correction verified;

• groundspeed and any direct aircraft airspeed source, correctly labeled and distinguished from eIAS.

‍

What data cannot prove without the right sensors

Portable telemetry may not capture:

• critical angle of attack;

• the exact full-stall moment;

• stall horn, buffet, or control feel;

• yaw rate, slip/skid, or rudder coordination;

• power, flap, gear, trim, or autopilot position;

• compliance with the POH/AFM sequence.

Do not score a stall solely from altitude loss or a generic pitch profile.

A safe debrief sequence

1. Setup: Was the area clear, altitude adequate, configuration correct, and flight coordinated?

2. Entry: Was the descent stable and the pitch change smooth?

3. Recognition: Which cues appeared, and when did the pilot identify the full stall?

4. First recovery action: Was angle of attack reduced immediately in accordance with the POH/AFM?

5. Control: Were yaw and bank managed without trying to force the wings level too early?

6. Power and configuration: Were they handled according to the airplane procedure?

7. Flight-path return: Was the recovery smooth, without a secondary stall or excessive speed?

8. Next lesson: Identify one correction that can be observed in the next repetition.

How FlytWERX can support the review

FlytWERX combines stall-maneuver tracking with available altitude, heading, groundspeed, vertical speed, pitch, bank, course, position, and flight-path data. For supported live-flight sessions, it also calculates eIAS using GPS-derived speed, current winds aloft, temperature, and the active wind correction. That can help reconstruct the entry and recovery. The CFI must still identify stall cues, coordination, the full-stall point, and compliance with the aircraft-specific recovery procedure.

Frequently asked questions

What does a power-off stall simulate?

It is generally used to develop awareness of stalls associated with approach and landing conditions, including straight and turning scenarios.

Can an airplane stall above its published stall speed?

Yes. A stall occurs when critical angle of attack is exceeded. Load factor, bank, weight, configuration, and other conditions affect the airspeed at which that happens.

What is the first priority in stall recovery?

Reduce angle of attack according to the current POH/AFM procedure.

How much altitude may be lost on the private-pilot task?

The ACS does not prescribe one predetermined altitude-loss value and does not require maintaining altitude during recovery.

Can telemetry identify a full stall automatically?

Only if the system has suitable, validated stall/AOA-related inputs. Pitch, groundspeed, and vertical speed alone do not prove the exact full-stall point.

Can eIAS identify the exact stall point?

No. eIAS can provide useful speed context, but a stall is defined by critical angle of attack. The exact stall event also depends on cues and information that may not be recorded, including buffet, stall warning, control feel, coordination, configuration, and load factor.
