Official task objective
To determine the applicant understands before takeoff checks, 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.
- V identifies Preflight Procedures, the Area of Operation.
- E identifies Before Takeoff Check, 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.V.E.K1 | Purpose of before takeoff checklist items, including: | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| IL.V.E.K1a | a. Reasons for checking each item | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| IL.V.E.K1b | b. Detecting malfunctions | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| IL.V.E.K1c | c. Configuring the aircraft as recommended by the manufacturer | 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.V.E.R1 | Division of attention while conducting before takeoff checks. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IL.V.E.R2 | Unexpected runway changes. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IL.V.E.R3 | Unexpected or unclear clearances from ATC. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IL.V.E.R4 | Wake turbulence. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IL.V.E.R5 | Downwash. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IL.V.E.R6 | Potential powerplant failure during takeoff or other malfunction considering operational factors such as aircraft characteristics, runway/takeoff path length, surface conditions, environmental conditions, and obstructions. | 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.V.E.S1 | Review takeoff performance. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| IL.V.E.S2 | Select the appropriate takeoff profile for aircraft and environmental conditions. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| IL.V.E.S3 | Complete the appropriate checklist(s). | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| IL.V.E.S4 | Properly position the aircraft considering other aircraft, vessels, and wind. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| IL.V.E.S5 | Divide attention inside and outside the aircraft. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| IL.V.E.S6 | Verify that powerplant parameters and aircraft configuration are suitable for the takeoff profile. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| IL.V.E.S7 | Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate. | 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.
