## Official Task objective

To determine the applicant understands the elements associated with a maneuver Task selected from Area of Operation VI through Area of Operation IX and applies that knowledge when delivering ground instruction.

## Knowledge elements

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

## Risk management elements

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

## Skills elements

- **PI.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.
