Official task objective
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with Commercial Pilot for Powered-Lift Category ACS (FAA-S-ACS-2) 33 Area of Operation VI. Performance Maneuvers converting from thrust-borne configuration to wing-borne configuration, and returning to thrust-borne configuration.
What the ACS code means
- CP identifies the ACS standard family used for this Commercial Pilot Powered Lift document.
- VI identifies Performance Maneuvers, the Area of Operation.
- B identifies Inflight Conversion During Straight-and-Level Flight, 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.

| CP.VI.B.S4 | Maintain awareness of aircraft performance, limitations, and relative position throughout the maneuver. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CP.VI.B.S5 | Maintain altitude ±100 feet and specified heading ±10° throughout the operation. Achieve and maintain targeted 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. |
| CP.VI.B.S6 | 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. |
| CP.VI.B.S7 | Use the appropriate checklist, 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.
