## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with powerplant failure during takeoff.

## Knowledge elements

- **AA.VII.B.K1** — The procedures used during a powerplant(s) failure on takeoff, the appropriate reference airspeeds, and the specific pilot actions required.
- **AA.VII.B.K2** — Operational considerations, including: airplane performance (e.g., sideslip, bank angle, rudder input), takeoff warning systems, runway length, surface conditions, density altitude, wake turbulence, environmental conditions, obstructions, and other related factors that could adversely affect safety.

## Risk management elements

- **AA.VII.B.R1** — Planning for a potential powerplant failure during takeoff considering operational factors (e.g., takeoff warning inhibit systems, other airplane characteristics, runway/takeoff path length, surface conditions, environmental conditions, obstructions, and land and hold short operations.
- **AA.VII.B.R2** — Briefing the plan for a powerplant failure during takeoff, in a crew environment.
- **AA.VII.B.R3** — Selection of the procedures or checklists to follow in an emergency.
- **AA.VII.B.R4** — Identifying the inoperative engine (AMEL, AMES).
- **AA.VII.B.R5** — Inability to climb or maintain altitude with an inoperative powerplant (AMEL, AMES).
- **AA.VII.B.R6** — Altitude, wind, terrain, and obstruction considerations in an emergency.
- **AA.VII.B.R7** — Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).
- **AA.VII.B.R8** — Distractions, task prioritization, loss of situational awareness, or disorientation.

## Skills elements

- **AA.VII.B.S1** — Following the powerplant failure, maintain positive airplane control and adjust the powerplant controls as recommended by the manufacturer for the existing conditions.
- **AA.VII.B.S2** — Establish a power-off descent approximately straight-ahead if the powerplant failure occurs after becoming airborne and before reaching an altitude where a safe turn can be made (ASEL, ASES) or the performance capabilities and operating limitations of the airplane do not allow the climb to continue (AMEL, AMES).
- **AA.VII.B.S3** — Continue the takeoff if the (simulated) powerplant failure occurs at a point where the airplane can continue to a specified airspeed and altitude at the end of the runway commensurate with the airplane’s performance capabilities and operating limitations (AMEL, AMES).
- **AA.VII.B.S4** — After establishing a climb, maintain the desired airspeed, ±5 knots. Use flight controls in the proper combination as recommended by the manufacturer, or as required, to maintain best performance and trim as required (AMEL, AMES).
- **AA.VII.B.S5** — Maintain the appropriate heading, ±5°, when powerplant failure occurs (AMEL, AMES).
- **AA.VII.B.S6** — Coordinate with crew, if applicable, and complete the appropriate checklist(s) following the powerplant failure.
- **AA.VII.B.S7** — 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.
