Official task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with operating an aircraft within the parameters of its performance capabilities and limitations.

What the ACS code means

  • CP identifies the ACS standard family used for this Commercial Pilot Powered Lift document.
  • I identifies Preflight Preparation, the Area of Operation.
  • F identifies Performance and Limitations, 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.

Risk management elements

Official ACS risk management items and mock-oral treatment
ACS codeOfficial descriptionHow a mock oral can probe it
CP.I.F.R1Use of performance charts, tables, and data.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
CP.I.F.R2Aircraft limitations.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
CP.I.F.R3Possible differences between calculated performance and actual performance.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
CP.I.F.R4Operations within “avoid areas” of the H/V diagram.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
CP.I.F.R5Other hazards specific to the powered-lift make and model.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.

Skills elements

Official ACS skills items and mock-oral treatment
ACS codeOfficial descriptionHow a mock oral can probe it
CP.I.F.S1Compute the weight and balance, correct out-of-center of gravity loading errors and determine if the weight and balance remains within limits during all phases of flight and aircraft configurations.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
CP.I.F.S2Use of the appropriate manufacturer’s approved performance charts, tables, and data.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.
