## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with flight and performance characteristics unique to a specific aircraft type.

## Knowledge elements

- **AA.IV.C.K1** — All specific flight and performance characteristics associated with the aircraft.

## Risk management elements

- **AA.IV.C.R1** — Specific flight and performance characteristics, their effects, and applicable procedures.
- **AA.IV.C.R2** — Distractions, task prioritization, loss of situational awareness, or disorientation.

## Skills elements

- **AA.IV.C.S1** — Use proper techniques, checklists, and procedures to enter into, operate within, and recover from specific flight situations, as applicable.

## 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 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.
