## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with rapid deceleration/quick stop and conditions that may require a rapid deceleration/quick stop.

## Knowledge elements

- **PL.VI.A.K1** — Purpose of the maneuver.
- **PL.VI.A.K2** — Aircraft transmission and powerplant limitations.
- **PL.VI.A.K3** — Airspeed limitations.
- **PL.VI.A.K4** — Aircraft maximum rate deceleration rate and technique.
- **PL.VI.A.K5** — Height velocity (H/V) awareness.

## Risk management elements

- **PL.VI.A.R1** — Gaining or losing altitude.
- **PL.VI.A.R2** — Excessive pitch attitudes.
- **PL.VI.A.R3** — Effects of wind.
- **PL.VI.A.R4** — Airframe and airspeed limitations.
- **PL.VI.A.R5** — Collision hazards.
- **PL.VI.A.R6** — Dividing attention between aircraft control and orientation.
- **PL.VI.A.R7** — Distractions, task prioritization, loss of situational awareness, or disorientation.
- **PL.VI.A.R8** — Uncoordinated flight.
- **PL.VI.A.R9** — Vortex ring state (VRS).

## Skills elements

- **PL.VI.A.S1** — Complete the appropriate checklist(s).
- **PL.VI.A.S2** — Clear the area.
- **PL.VI.A.S3** — Maintain heading throughout the maneuver, ±10°.
- **PL.VI.A.S4** — Perform a maximum performance deceleration as directed by the evaluator.
- **PL.VI.A.S5** — Select an appropriate power setting and thrust vector to allow deceleration at maximum rate.
- **PL.VI.A.S6** — Maintain coordinated flight throughout the maneuver.

## 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.
