Official task objective
To determine the applicant understands logbook entries and endorsements, 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.
- K identifies Endorsements and Logbook Entries, 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 code | Official description | How a mock oral can probe it |
|---|---|---|
| AI.II.K.K1 | Required logbook entries for instruction given. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| AI.II.K.K2 | Required student pilot pre-solo knowledge test, solo endorsements, and logbook entries. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| AI.II.K.K3 | Other required pilot logbook endorsements (e.g., Class B Airspace, Special Federal Aviation Regulation (SFAR)). | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| AI.II.K.K4 | Preparation of a recommendation for a pilot practical test, including appropriate logbook entry and relevant certificate/rating application for: | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| AI.II.K.K4a | Initial pilot certification | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| AI.II.K.K4b | Additional pilot certification | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| AI.II.K.K4c | Additional aircraft qualification | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| AI.II.K.K5 | Endorsement of a pilot logbook for the satisfactory completion of an FAA flight review. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| AI.II.K.K6 | Required flight instructor records. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| AI.II.K.K7 | Flight instructor renewal and reinstatement requirements. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
Risk management elements
| ACS code | Official description | How a mock oral can probe it |
|---|---|---|
| AI.II.K.R1 | Endorsements without appropriate limitations or expiration dates. | 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 |
|---|---|---|
| AI.II.K.S1 | Describe and prepare logbook entries/endorsements required for at least two of the events specified in the elements or sub-elements of K1 through K5. | 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.
