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.
What the ACS code means
- AA identifies the ACS standard family used for this Airline Transport Pilot Airplane document.
- I identifies Preflight Preparation, the Area of Operation.
- F identifies Human Factors (ATP), the Task within that Area.
- K, R, and S identify knowledge, risk-management, and skill elements. The number selects the item; a trailing lowercase letter identifies a listed sub-element.

Risk management elements
| ACS code | Official description | How a mock oral can probe it |
|---|---|---|
| AA.I.F.R1 | Aeromedical and physiological issues. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| AA.I.F.R2 | Hazardous attitudes. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| AA.I.F.R3 | Distractions, task prioritization, loss of situational awareness, or disorientation. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| AA.I.F.R4 | Confirmation and expectation bias. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
Skills elements
| ACS code | Official description | How a mock oral can probe it |
|---|---|---|
| AA.I.F.S1 | Perform a self-assessment and determine fitness for flight. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
Difficulty data
Difficulty calibration is ongoing for this Task. A difficulty estimate is published only with a sufficiently large, privacy-preserving first directly recorded assessment sample. Any observed difficulty comes from Checkride AI mock-oral practice assessments and is a practice-data proxy, not an FAA practical-test pass or fail rate.
Difficulty calibration remains ongoing until an item clears the private reporting threshold. Percentages, when available, describe the share who needed review on their first directly recorded assessment. Underlying sample sizes are never published, and historical final states are not backfilled into this measure.
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.
How to use this in a mock oral
A mock examiner can ask you to explain the published elements, apply them to the configured aircraft and airport scenario, identify risks, and defend a decision. The prompts are practice scenarios; they are not claimed to be actual FAA examiner scripts or a prediction of the questions you will receive.
