## Official Task objective

To determine the applicant understands indications and pilot actions after powerplant(s) failure during takeoff while the aircraft is predominantly in thrust-borne flight in a multi-powerplant aircraft, can apply that knowledge, manage associated risks, demonstrate appropriate skills, and provide effective instruction.

## Knowledge elements

- **IL.XIV.A.K1** — Aircraft performance and limitations, (e.g., height velocity (H/V) diagram information).
- **IL.XIV.A.K2** — Factors involved in determining a valid go/no-go decision.
- **IL.XIV.A.K3** — Recognition of powerplant(s) failure.
- **IL.XIV.A.K4** — Pilot actions required on recognition of powerplant(s) failure, including checklist memory items.
- **IL.XIV.A.K5** — Aircraft configuration for landing with powerplant(s) failure.
- **IL.XIV.A.K6** — Causes of asymmetric thrust conditions and appropriate responses.
- **IL.XIV.A.K7** — Common errors related to this Task.

## Risk management elements

- **IL.XIV.A.R1** — Powerplant(s) failure.
- **IL.XIV.A.R2** — Identification of powerplant(s) failure conditions.
- **IL.XIV.A.R3** — Pilot reaction to powerplant(s) failure conditions.
- **IL.XIV.A.R4** — Aircraft configuration.

## Skills elements

- **IL.XIV.A.S1** — Recognize that a powerplant(s) failure has occurred.
- **IL.XIV.A.S2** — Use flight controls in the proper combination and aircraft configuration as recommended by the manufacturer, or as required to maintain best performance, and trim as required.
- **IL.XIV.A.S3** — Maintain the operating powerplant(s) within acceptable operating limits.
- **IL.XIV.A.S4** — Land the aircraft, as appropriate to the scenario presented by the evaluator.
- **IL.XIV.A.S5** — Complete the appropriate checklist(s).
- **IL.XIV.A.S6** — Make radio calls as appropriate.
- **IL.XIV.A.S7** — Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.
- **IL.XIV.A.S8** — Analyze and correct common errors related to this Task.

## 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.
- The task outcome can be vertical or rolling depending on aircraft capabilities, configuration, and flight manual procedures.

## 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.
