## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with maximum performance takeoff and climb.

## Knowledge elements

- **PH.V.C.K1** — Situations where this maneuver is appropriate.
- **PH.V.C.K2** — Effects of atmospheric conditions, including wind and temperature, on takeoff and climb performance.
- **PH.V.C.K3** — Factors affecting the profile of the height/velocity (H/V) diagram.

## Risk management elements

- **PH.V.C.R1** — Selection of takeoff path based on helicopter performance and limitations, available distance, and wind.
- **PH.V.C.R2** — Effects of:
- **PH.V.C.R2a** — a. Crosswind
- **PH.V.C.R2b** — b. Windshear
- **PH.V.C.R2c** — c. Tailwind
- **PH.V.C.R2d** — d. Turbulence, including wake turbulence
- **PH.V.C.R2e** — e. Surface conditions
- **PH.V.C.R3** — Abnormal operations including:
- **PH.V.C.R3a** — a. Rejected takeoff
- **PH.V.C.R3b** — b. Powerplant failure in takeoff/climb phase of flight
- **PH.V.C.R4** — Collision hazards.
- **PH.V.C.R5** — Low rotor rpm.
- **PH.V.C.R6** — Distractions, task prioritization, loss of situational awareness, or disorientation.

## Skills elements

- **PH.V.C.S1** — Complete the appropriate checklist(s).
- **PH.V.C.S2** — Make radio calls as appropriate.
- **PH.V.C.S3** — Use control inputs to initiate lift-off from the takeoff position using a forward climb attitude to fly the departure profile.
- **PH.V.C.S4** — Maintain powerplant and rotor rpm within normal limits.
- **PH.V.C.S5** — Use required takeoff power, or power as specified by the evaluator.
- **PH.V.C.S6** — After clearing all obstacles, transition to normal climb attitude, airspeed, ±5 knots, and power setting.
- **PH.V.C.S7** — Maintain directional control, ground track, and proper wind-drift correction 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.
