## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with engine failure during takeoff before minimum controllable airspeed (VMC).

## Knowledge elements

- **PA.IX.E.K1** — Factors affecting minimum control airspeed with an inoperative engine (VMC).
- **PA.IX.E.K2** — VMC (red line) and best single-engine rate of climb airspeed (VYSE) (blue line).
- **PA.IX.E.K3** — Accelerate/stop distance.

## Risk management elements

- **PA.IX.E.R1** — Potential engine failure during takeoff.
- **PA.IX.E.R2** — Configuring the airplane.
- **PA.IX.E.R3** — Distractions, task prioritization, loss of situational awareness, or disorientation.

## Skills elements

- **PA.IX.E.S1** — Close the throttles smoothly and promptly when a simulated engine failure occurs.
- **PA.IX.E.S2** — Maintain directional control and apply brakes (AMEL), or flight controls (AMES), as necessary.

## 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.
