Official task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with flight and performance characteristics unique to a specific aircraft type.

What the ACS code means

  • AA identifies the ACS standard family used for this Airline Transport Pilot Airplane document.
  • IV identifies In-flight Maneuvers, the Area of Operation.
  • C identifies Specific Flight Characteristics, 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.

Knowledge elements

Official ACS knowledge items and mock-oral treatment
ACS codeOfficial descriptionHow a mock oral can probe it
AA.IV.C.K1All specific flight and performance characteristics associated with the aircraft.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.

Risk management elements

Official ACS risk management items and mock-oral treatment
ACS codeOfficial descriptionHow a mock oral can probe it
AA.IV.C.R1Specific flight and performance characteristics, their effects, and applicable procedures.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
AA.IV.C.R2Distractions, 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.

Skills elements

Official ACS skills items and mock-oral treatment
ACS codeOfficial descriptionHow a mock oral can probe it
AA.IV.C.S1Use proper techniques, checklists, and procedures to enter into, operate within, and recover from specific flight situations, as applicable.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

  • See 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.
