- **PL.II.D.K2** — Taxi instructions/clearances.
- **PL.II.D.K3** — Airport/heliport/helipad/landing area, signs, markings, and lighting.
- **PL.II.D.K4** — Visual indicators for wind.
- **PL.II.D.K5** — Aircraft lighting, as appropriate.
- **PL.II.D.K6** — Procedures for:
- **PL.II.D.K6a** — a. Appropriate flight deck activities prior to taxi, including route planning and identifying the location of Hot Spots
- **PL.II.D.K6b** — b. Aircraft configuration
- **PL.II.D.K6c** — c. Radio communications at towered and non-towered airports/heliports/helipads/landing areas
- **PL.II.D.K6d** — d. Entering or crossing runways
- **PL.II.D.K6e** — e. Night taxi operations
- **PL.II.D.K6f** — f. Taxi limitations

## Risk management elements

- **PL.II.D.R1** — Activities and distractions.
- **PL.II.D.R2** — Confirmation or expectation bias as related to taxi instructions.
- **PL.II.D.R3** — A taxi route or departure runway change.
- **PL.II.D.R4** — Speed during taxi and turns.
- **PL.II.D.R5** — Appropriate thrust vector and brake use.
- **PL.II.D.R6** — Airframe and rotor clearances during taxi.
- **PL.II.D.R7** — Runway incursion.
- **PL.II.D.R8** — Other hazards specific to the powered-lift make and model.

## Skills elements

- **PL.II.D.S1** — Receive and correctly read back clearances/instructions, if applicable.
- **PL.II.D.S2** — Use an appropriate airport/heliport diagram or taxi chart, if published.
- **PL.II.D.S3** — Position the flight controls and configure the aircraft for the existing wind conditions.
- **PL.II.D.S4** — Complete the appropriate checklist(s).
- **PL.II.D.S5** — Maintain positive control of the aircraft during ground operations by controlling direction and speed without excessive use of brakes.
- **PL.II.D.S6** — Comply with airport/heliport/helipad/landing area taxiway markings, signals, and air traffic control (ATC) clearances and instructions.
- **PL.II.D.S7** — Position the aircraft relative to hold lines or a specified point.
- **PL.II.D.S8** — 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.

## 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.
