Official task objective
To determine the applicant understands airport/runway/ taxiway/heliport/helipad signs, markings, and lighting, can apply that knowledge, manage associated risks, demonstrate appropriate skills, and provide effective instruction.
What the ACS code means
- IL identifies the ACS standard family used for this Flight Instructor Powered Lift document.
- VI identifies Airport and Heliport Operations, the Area of Operation.
- A identifies Runway/Taxiway/Heliport/Helipad Signs, Markings, and Lighting, 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 |
|---|---|---|
| IL.VI.A.K1 | Airport runway, heliport, helipad, taxiway signs, markings, and lighting. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| IL.VI.A.K2 | Airport movement area. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| IL.VI.A.K3 | Common errors related to this Task. | 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 |
|---|---|---|
| IL.VI.A.R1 | Interpretation of signs, markings, or lighting. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IL.VI.A.R2 | Landing site dimensions and limitations. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IL.VI.A.R3 | Conflict with aircraft, vehicles, and persons. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IL.VI.A.R4 | Distractions, 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. |
| IL.VI.A.R5 | Powered-lift configuration, including the effect of thrust on other aircraft. | 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 |
|---|---|---|
| IL.VI.A.S1 | Comply with airport/heliport/helipad signs, markings, and lighting encountered, as applicable to the aircraft provided for the practical test. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| IL.VI.A.S2 | Analyze and correct common errors related to this Task. | 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.
