## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with ATC clearances and procedures while operating solely by reference to instruments, and provide effective instruction.

## Knowledge elements

- **PI.V.A.K1** — Elements and procedures related to ATC clearances and pilot/controller responsibilities for departure, en route, and arrival phases of flight, including clearance void times.
- **PI.V.A.K2** — Pilot-in-Command (PIC) emergency authority.
- **PI.V.A.K3** — Lost communication procedures and procedures for flights outside of radar environments.
- **PI.V.A.K4** — Common errors related to this Task.

## Risk management elements

- **PI.V.A.R1** — Less than full understanding of an ATC clearance.
- **PI.V.A.R2** — Inappropriate, incomplete, or incorrect ATC clearances.
- **PI.V.A.R3** — ATC clearance inconsistent with aircraft performance or navigation capability.
- **PI.V.A.R4** — ATC clearance intended for other aircraft with similar call signs.

## Skills elements

- **PI.V.A.S1** — Correctly copy, read back, interpret, and comply with simulated or actual ATC clearances in a timely manner using standard phraseology as provided in the Aeronautical Information Manual (AIM).
- **PI.V.A.S2** — Correctly set communication frequencies, navigation systems (identifying when appropriate), and transponder codes in compliance with the ATC clearance.
- **PI.V.A.S3** — Use the current and appropriate paper or electronic navigation publications.
- **PI.V.A.S4** — Intercept all courses, radials, and bearings appropriate to the procedure, route, or clearance in a timely manner.
- **PI.V.A.S5** — Maintain the applicable airspeed ±10 knots, headings ±10°, altitude ±100 feet; track a course, radial, or bearing within ¾-scale deflection of the course deviation indicator (CDI).
- **PI.V.A.S6** — Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.
- **PI.V.A.S7** — Perform the appropriate checklist items relative to the phase of flight.
- **PI.V.A.S8** — Analyze and correct common errors related to this Task.

## 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.
