Official task objective
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with traffic patterns.
What the ACS code means
- CA identifies the ACS standard family used for this Commercial Pilot Airplane document.
- III identifies Airport and Seaplane Base Operations, the Area of Operation.
- B identifies Traffic Patterns, 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.III.B.K1 | Towered and nontowered airport operations. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| CA.III.B.K2 | Traffic pattern selection for the current conditions. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| CA.III.B.K3 | Right-of-way rules. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| CA.III.B.K4 | Use of automated weather and airport information. | 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.III.B.R1 | Collision hazards. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| CA.III.B.R2 | 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. |
| CA.III.B.R3 | Windshear and wake turbulence. | 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.III.B.S1 | Identify and interpret airport/seaplane base runways, taxiways, markings, signs, and lighting. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.III.B.S2 | Comply with recommended traffic pattern procedures. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.III.B.S3 | Correct for wind drift to maintain the proper ground track. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.III.B.S4 | Maintain orientation with the runway/landing area in use. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.III.B.S5 | Maintain traffic pattern altitude, ±100 feet, and the appropriate airspeed, ±10 knots. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.III.B.S6 | Maintain situational awareness and proper spacing from other aircraft in the traffic pattern. | 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.
