Official task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with preparation for safe flight.

What the ACS code means

  • AA identifies the ACS standard family used for this Airline Transport Pilot Airplane document.
  • II identifies Preflight Procedures, the Area of Operation.
  • A identifies Preflight Assessment, 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.

Skills elements

Official ACS skills items and mock-oral treatment
ACS codeOfficial descriptionHow a mock oral can probe it
AA.II.A.S1Inspect the aircraft in accordance with an appropriate checklist demonstrating proper operation of applicable airplane systems. Coordinate checklist with crew, if appropriate.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.II.A.S2Coordinate with ground crew and ensure adequate clearance prior to moving doors, hatches, flight control surfaces, etc.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.II.A.S3Document any discrepancies found; take corrective action and acknowledge limitations imposed by MEL/CDL items, if applicable.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.II.A.S4Determine if the aircraft is airworthy and in condition for safe flight.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.II.A.S5Identify and comply with operations specifications as required.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.II.A.S6Assess factors related to the environment (weather, airports, terrain, airspace).Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.II.A.S7Ensure the airplane and surfaces are free of ice, snow, and frost. If icing conditions are present, demonstrate satisfactory knowledge of deicing procedures.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.

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.
