## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with air carrier operations.

## Knowledge elements

- **AA.I.E.K1** — Turbine engines, thrust reversing systems, and system malfunctions.
- **AA.I.E.K2** — Airplane automation components (e.g., flight director, autopilot), their relationship to each other, and how to manage the automation for flight.
- **AA.I.E.K3** — Advanced navigation equipment (e.g., FMS, Required Navigation Performance (RNP), ADS-B, EFB, etc.) and how it is used inflight.
- **AA.I.E.K4** — Flightpath warning systems (e.g., Traffic Alert and Collision Avoidance Systems (TCAS), Terrain Awareness and Warning System (TAWS) and how to respond to a warning.
- **AA.I.E.K5** — Altitudes and conditions that require the use of oxygen masks.
- **AA.I.E.K6** — Causes and recognition of cabin pressure loss.
- **AA.I.E.K7** — Appropriate rudder use in transport aircraft to avoid rudder reversal.
- **AA.I.E.K8** — Crew communications (e.g., sterile flight deck rules, briefings).
- **AA.I.E.K9** — Operational control.
- **AA.I.E.K10** — Elements associated with operating at complex and high traffic airports with emphasis on runway incursion prevention techniques.
- **AA.I.E.K11** — Professional responsibilities associated with being an ATP certificate holder and how to apply leadership skills as pilot-in-command.
- **AA.I.E.K12** — Crew resource management (CRM) principles and application in a multi-crew environment.
- **AA.I.E.K13** — Use of safety programs to manage risk across an organization (e.g., Threat and error management (TEM), or Aviation Safety Action Program (ASAP)).
- **AA.I.E.K14** — Operations specifications.

## Risk management elements

- **AA.I.E.R1** — Turbine engine and thrust reversing system malfunctions.
- **AA.I.E.R2** — Managing automation and navigation equipment.
- **AA.I.E.R3** — Responding to a flightpath warning system alert.
- **AA.I.E.R4** — Loss of cabin pressure.
- **AA.I.E.R5** — Crew coordination.

## Skills elements

- **AA.I.E.S1** — Apply CRM principles and use in a crew environment, as appropriate.

## 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

- Note: 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.
