## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with slope operations.

## Knowledge elements

- **CP.XI.B.K1** — Elements related to slope operations.
- **CP.XI.B.K2** — Factors used for selecting an appropriate slope.
- **CP.XI.B.K3** — Effect of wind on slope operations.
- **CP.XI.B.K4** — Dynamic rollover considerations during slope operations and preventive/recovery techniques.
- **CP.XI.B.K5** — Aircraft configuration and slope limitations.

## Risk management elements

- **CP.XI.B.R1** — Aircraft configuration.
- **CP.XI.B.R2** — Operations on a slope.
- **CP.XI.B.R3** — Conditions leading to dynamic rollover.
- **CP.XI.B.R4** — Flight control limits.
- **CP.XI.B.R5** — Surface conditions.
- **CP.XI.B.R6** — Embarking or disembarking passengers.
- **CP.XI.B.R7** — Exceeding the manufacturer's slope limitations.

## Skills elements

- **CP.XI.B.S1** — Select a suitable slope.
- **CP.XI.B.S2** — Complete the appropriate checklist(s).
- **CP.XI.B.S3** — Position the primary flight controls, including the thrust vector, for the prevailing environmental conditions.
- **CP.XI.B.S4** — Maintain heading and ground position and prevent movement of aircraft on slope.
- **CP.XI.B.S5** — Recognize if slope is too steep and abandon the operation prior to reaching flight control limits.
- **CP.XI.B.S6** — Make a smooth positive descent to touch the upslope landing gear on the sloping surface.
- **CP.XI.B.S7** — Neutralize controls after landing.
- **CP.XI.B.S8** — Make a smooth transition from the slope to a stabilized hover parallel to the slope.
- **CP.XI.B.S9** — Properly move away from the slope.
- **CP.XI.B.S10** — Maintain positive control of aircraft throughout the maneuver.
- **CP.XI.B.S11** — Use controls while lowering the downslope landing gear to touchdown.
- **CP.XI.B.S12** — Maintain specified headings throughout the operation, ±5°.
- **CP.XI.B.S13** — Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.

## 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.
