Official task objective

To determine the applicant understands the elements associated with a maneuver Task selected from Area of Operation VII (Hovering Maneuvers) through Area of Operation XII (Special Operations) and applies that knowledge when delivering ground instruction.

What the ACS code means

  • HI identifies the ACS standard family used for this Flight Instructor Rotorcraft document.
  • IV identifies Preflight Lesson on a Maneuver to be Performed in Flight, the Area of Operation.
  • A identifies Maneuver Lesson, 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

ACS codeOfficial descriptionHow a mock oral can probe it
HI.IV.A.K1Purpose of the maneuver.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
HI.IV.A.K2Elements of the maneuver and the associated common errors.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
HI.IV.A.K3Desired outcome(s), including completion standards.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.

Risk management elements

HI.IV.A.R1The selected maneuver Task.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
HI.IV.A.S1Deliver instruction on the selected maneuver using a lesson plan, teaching methods, and teaching aids, as appropriate, that incorporate K1 through K3.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.
