## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with National Airspace System (NAS) operations under VFR as a private pilot.

## Knowledge elements

- **PL.I.E.K1** — Airspace classes and associated requirements and limitations.
- **PL.I.E.K2** — Chart symbols.
- **PL.I.E.K3** — Special use airspace (SUA), special flight rules areas (SFRA), temporary flight restrictions (TFR), and other airspace areas.
- **PL.I.E.K4** — Special visual flight rules (VFR) requirements.

## Risk management elements

- **PL.I.E.R1** — Various classes and types of airspace.

## Skills elements

- **PL.I.E.S1** — Identify and comply with the requirements for basic VFR weather minimums and flying in particular classes of airspace.
- **PL.I.E.S2** — Correctly identify airspace and operate in accordance with associated communication and equipment requirements.
- **PL.I.E.S3** — Identify the requirements for operating in SUA or within a TFR. Identify and comply with special air traffic rules (SATR) and SFRA operations, if applicable.

## 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.
