## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with powerplant failure and associated emergency approach and landing procedures.

## Knowledge elements

- **AA.VII.C.K1** — Immediate action items and emergency procedures for a forced landing.
- **AA.VII.C.K2** — Airspeed, including:
- **AA.VII.C.K2a** — a. Importance of best glide speed and its relationship to distance
- **AA.VII.C.K2b** — b. Difference between best glide speed and minimum sink speed
- **AA.VII.C.K2c** — c. Effects of wind on glide distance
- **AA.VII.C.K3** — Effects of atmospheric conditions on emergency approach and landing.
- **AA.VII.C.K4** — A stabilized approach, including energy management concepts.
- **AA.VII.C.K5** — Emergency Locator Transmitters (ELTs) and other emergency locating devices.
- **AA.VII.C.K6** — Air traffic control (ATC) services to aircraft in distress.

## Risk management elements

- **AA.VII.C.R1** — Altitude, wind, terrain, obstructions, gliding distance, and available landing distance considerations.
- **AA.VII.C.R2** — Following or changing the planned flightpath to the selected landing area.
- **AA.VII.C.R3** — Collision hazards.
- **AA.VII.C.R4** — Configuring the airplane.
- **AA.VII.C.R5** — Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).
- **AA.VII.C.R6** — Distractions, task prioritization, loss of situational awareness, or disorientation.
- **AA.VII.C.R7** — A powerplant failure in Instrument Meteorological Conditions (IMC).

## Skills elements

- **AA.VII.C.S1** — Recognize the powerplant failure.
- **AA.VII.C.S2** — Determine the cause for the simulated powerplant failure (if altitude permits) and if a restart is a viable option.
- **AA.VII.C.S3** — Maintain positive control throughout the maneuver.
- **AA.VII.C.S4** — Establish and maintain the recommended best glide airspeed, ±5 knots.
- **AA.VII.C.S5** — Configure the airplane in accordance with the Pilot's Operating Handbook (POH)\Airplane Flight Manual (AFM) and existing conditions.
- **AA.VII.C.S6** — Select a suitable landing area considering altitude, wind, terrain, obstructions, and available glide distance.
- **AA.VII.C.S7** — Establish a proper flight path to the selected landing area.
- **AA.VII.C.S8** — Complete emergency checklist items appropriate to the airplane in a timely manner and as recommended by the manufacturer or operator.
- **AA.VII.C.S9** — Communicate with air traffic control (ATC) and the evaluator, as appropriate for the situation.

## 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.
