Official task objective
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with National Airspace System (NAS) operations under VFR as a commercial pilot.
What the ACS code means
- CA identifies the ACS standard family used for this Commercial Pilot Airplane document.
- I identifies Preflight Preparation, the Area of Operation.
- E 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
| ACS code | Official description | How a mock oral can probe it |
|---|---|---|
| CA.I.E.K1 | Airspace 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. |
| CA.I.E.K2 | Chart symbols. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| CA.I.E.K3 | Special 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. |
| CA.I.E.K4 | Special 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
| ACS code | Official description | How a mock oral can probe it |
|---|---|---|
| CA.I.E.R1 | Various 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
| ACS code | Official description | How a mock oral can probe it |
|---|---|---|
| CA.I.E.S1 | Identify 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. |
| CA.I.E.S2 | Correctly 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. |
| CA.I.E.S3 | Identify 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.
