## Official Task objective

To determine the applicant understands the elements associated with a maneuver Task selected from Area of Operation VII through Area of Operation XII (ASEL, ASES) or Area of Operation VII through Area of Operation XIII (AMEL, AMES) and applies that knowledge when delivering ground instruction.

## Knowledge elements

- **AI.IV.A.K1** — Purpose of the maneuver.
- **AI.IV.A.K2** — Elements of the maneuver and the associated common errors.
- **AI.IV.A.K3** — Desired outcome(s), including completion standards.

## Risk management elements

- **AI.IV.A.R1** — The selected maneuver Task.

## Skills elements

- **AI.IV.A.S1** — Deliver instruction on the selected maneuver using a lesson plan, teaching methods, and teaching aids, as appropriate, that incorporate K1 through K3.

## 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.

## 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.
