Official task objective

To determine the applicant understands the National Airspace System, can apply that knowledge, manage associated risks, demonstrate appropriate skills, and provide effective instruction.

What the ACS code means

  • AI identifies the ACS standard family used for this Flight Instructor Airplane document.
  • II identifies Technical Subject Areas, the Area of Operation.
  • G identifies National Airspace System, 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
AI.II.G.K1Airspace classes and associated requirements and limitations.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
AI.II.G.K2Chart symbols.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
AI.II.G.K3Special use airspace (SUA), special flight rules areas (SFRA), temporary flight restrictions (TFR), and other airspace areas.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
AI.II.G.K4Currency of publications.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
AI.II.G.K5Special visual flight rules (VFR) requirements.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
AI.II.G.R1Various classes and types of airspace.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
AI.II.G.S1Identify and comply with the requirements for basic VFR weather minimums and flying in particular classes of airspace.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AI.II.G.S2Correctly identify airspace and operate in accordance with associated communication and equipment requirements.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AI.II.G.S3Identify the requirements for operating in SUA or within a TFR. Identify and comply with special air traffic rules (SATR) and SFRA operations, 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.

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.
