## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with stalls in the landing configuration

## Knowledge elements

- **AA.V.C.K1** — Aerodynamics associated with stalls in the landing configuration, including the relationship between angle of attack, airspeed, load factor, power setting, aircraft weight and balance, aircraft attitude, and sideslip effects.
- **AA.V.C.K2** — Stall characteristics as they relate to airplane design, and recognition impending stall and full stall indications using sight, sound, or feel.
- **AA.V.C.K3** — Factors and situations that can lead to a stall when configured for landing and actions that can be taken to prevent it.
- **AA.V.C.K4** — Effects of autoflight, flight envelope protection in normal and degraded modes, and unexpected disconnects of the autopilot or autothrottle/autothrust, if applicable to the aircraft used for the evaluation.
- **AA.V.C.K5** — Fundamentals of stall recovery.

## Risk management elements

- **AA.V.C.R1** — Factors and situations that could lead to an inadvertent stall, spin, and loss of control during landing.
- **AA.V.C.R2** — Range and limitations of stall warning indicators (e.g., aircraft buffet, stall horn, stick shaker, etc.).
- **AA.V.C.R3** — Stall warning awareness.
- **AA.V.C.R4** — Stall recovery procedure.
- **AA.V.C.R5** — Secondary stalls, accelerated stalls, elevator trim stalls, and cross-control stalls.
- **AA.V.C.R6** — Effect of environmental elements on aircraft performance while landing as it relates to stalls (e.g., turbulence, icing, microbursts, and high-density altitude).
- **AA.V.C.R7** — Stalls at a low altitude.
- **AA.V.C.R8** — Collision hazards, including aircraft and terrain.
- **AA.V.C.R9** — Distractions, task prioritization, loss of situational awareness, or disorientation.

## Skills elements

- **AA.V.C.S1** — Clear the area and select an entry altitude that allows the recovery to be completed no lower than 3,000 feet above ground level (AGL) (non-transport category airplanes) or 5,000 feet AGL (transport category airplanes).
- **AA.V.C.S2** — [Archived]
- **AA.V.C.S3** — Establish the landing configuration (i.e., lift/drag devices set and landing gear extended) and maintain coordinated flight in simulated or actual instrument conditions throughout the maneuver.
- **AA.V.C.S4** — Either manually or with the autopilot engaged, smoothly adjust pitch attitude, bank angle (15°-30°), and power setting in accordance with evaluator’s instructions to an impending stall.
- **AA.V.C.S5** — Acknowledge the cue(s) and promptly recover at the first indication of an impending stall (e.g., buffet, stall horn, stick shaker, etc.).
- **AA.V.C.S6** — Execute a stall recovery in accordance with procedures set forth in the Pilot's Operating Handbook (POH)/Flight Manual (FM).
- **AA.V.C.S7** — Retract the flaps or other lift/drag devices to the recommended setting, if applicable; retract the landing gear after a positive rate of climb is established, if applicable; and return to the desired flight path as specified by the evaluator.

## Difficulty methodology

Difficulty calibration is ongoing for this Task. Observed difficulty is a privacy-thresholded check-ride.ai mock-oral practice proxy, not an FAA practical-test pass or fail rate. Underlying sample sizes and the private reporting threshold are not published.

## Official Task notes

- See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.

## Use in practice

A mock examiner can ask a pilot to explain the published elements, apply them to the configured aircraft and airport context, identify risks, and defend a decision. Practice prompts are not represented as actual FAA examiner scripts or predictions of the questions a candidate will receive.
