## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with dynamic rollover.

## Knowledge elements

- **PL.XI.I.K1** — Elements related to dynamic rollover.
- **PL.XI.I.K2** — Interactions between thrust, crosswind, slope, lateral CG, aircraft weight, and flight controls that contribute to dynamic rollover.
- **PL.XI.I.K3** — Preventive flight technique and recovery during flight operations, including slope operations.
- **PL.XI.I.K4** — Aircraft slope limitations.

## Risk management elements

- **PL.XI.I.R1** — Surface conditions conducive to dynamic rollover.
- **PL.XI.I.R2** — Landing gear proximity to the surface.
- **PL.XI.I.R3** — Flight control inputs during takeoff or landing.
- **PL.XI.I.R4** — Sideward hover.
- **PL.XI.I.R5** — Critical rollover angle and rolling moment.
- **PL.XI.I.R6** — Translating tendency.

## Skills elements

- **PL.XI.I.S1** — [Intentionally left blank].

## 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

- Evaluator assesses this Task orally only.

## 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.
