## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with personal health, flight physiology, and aeromedical and human factors related to safety of flight.

## Knowledge elements

- **AA.I.F.K1** — Causes, effects, recognition, and corrective actions associated with aeromedical and physiological issues, including:
- **AA.I.F.K1a** — a. Hypoxia
- **AA.I.F.K1b** — b. Hyperventilation
- **AA.I.F.K1c** — c. Middle ear and sinus problems
- **AA.I.F.K1d** — d. Spatial disorientation
- **AA.I.F.K1e** — e. Motion sickness
- **AA.I.F.K1f** — f. Carbon monoxide poisoning
- **AA.I.F.K1g** — g. Stress
- **AA.I.F.K1h** — h. Fatigue
- **AA.I.F.K1i** — i. Dehydration and nutrition
- **AA.I.F.K1j** — j. Hypothermia
- **AA.I.F.K1k** — k. Optical illusions
- **AA.I.F.K1l** — l. Dissolved nitrogen in the bloodstream after scuba dives
- **AA.I.F.K2** — Effects of alcohol, drugs, and over-the-counter medications.
- **AA.I.F.K3** — Aeronautical Decision-Making (ADM) to include using Crew Resource Management (CRM) or SinglePilot Resource Management (SRM), as appropriate.
- **AA.I.F.K4** — Components of self-assessment for determining fitness for flight.

## Risk management elements

- **AA.I.F.R1** — Aeromedical and physiological issues.
- **AA.I.F.R2** — Hazardous attitudes.
- **AA.I.F.R3** — Distractions, task prioritization, loss of situational awareness, or disorientation.
- **AA.I.F.R4** — Confirmation and expectation bias.

## Skills elements

- **AA.I.F.S1** — Perform a self-assessment and determine fitness for flight.

## 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.

## Official Task notes

- If K1 is selected, the evaluator must assess the applicant's knowledge of at least three sub-elements.
- See Appendix 1: Practical Test Roles, Responsibilities, and Outcomes and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.

## 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.
