## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with accelerated stalls (power-on or power-off).

## Knowledge elements

- **CA.VII.D.K1** — Aerodynamics associated with accelerated stalls in various airplane configurations, including the relationship between angle of attack, airspeed, load factor, power setting, airplane weight and center of gravity, airplane attitude, and yaw effects.
- **CA.VII.D.K2** — Stall characteristics as they relate to airplane design, and recognition impending stall and full stall indications using sight, sound, or feel.
- **CA.VII.D.K3** — Factors leading to an accelerated stall and preventive actions.
- **CA.VII.D.K4** — Fundamentals of stall recovery.

## Risk management elements

- **CA.VII.D.R1** — Factors and situations that could lead to an inadvertent accelerated stall, spin, and loss of control.
- **CA.VII.D.R2** — Range and limitations of stall warning indicators (e.g., aircraft buffet, stall horn, etc.).
- **CA.VII.D.R3** — Stall warning(s) during normal operations.
- **CA.VII.D.R4** — Stall recovery procedure.
- **CA.VII.D.R5** — Secondary stalls, cross-control stalls, and spins.
- **CA.VII.D.R6** — Effect of environmental elements on airplane performance related to accelerated stalls (e.g., turbulence, microbursts, and high-density altitude).
- **CA.VII.D.R7** — Collision hazards.
- **CA.VII.D.R8** — Distractions, task prioritization, loss of situational awareness, or disorientation.

## Skills elements

- **CA.VII.D.S1** — Clear the area.
- **CA.VII.D.S2** — Select an entry altitude that allows the Task to be completed no lower than 3,000 feet above ground level (AGL).
- **CA.VII.D.S3** — Establish the configuration as specified by the evaluator.
- **CA.VII.D.S4** — Set power appropriate for the configuration, such that the airspeed does not exceed the maneuvering speed (VA) or any other applicable Pilot's Operating Handbook (POH)/Airplane Flight Manual (AFM) limitation.
- **CA.VII.D.S5** — Establish and maintain a coordinated turn in a 45° bank, increasing elevator back pressure smoothly and firmly until an impending stall is reached.
- **CA.VII.D.S6** — Acknowledge the cues at the first indication of a stall (e.g., aircraft buffet, stall horn, etc.).
- **CA.VII.D.S7** — Execute a stall recovery in accordance with procedures set forth in the Pilot's Operating Handbook (POH)/Flight Manual (FM).
- **CA.VII.D.S8** — Configure the airplane as recommended by the manufacturer, and accelerate to best angle of climb speed (VX) or best rate of climb speed (VY).
- **CA.VII.D.S9** — Return to the altitude, heading, and airspeed 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.
