Official task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with radio communications, navigation systems/facilities, and radar services available for use during flight solely by reference to instruments.

What the ACS code means

  • PL identifies the ACS standard family used for this Private Pilot Powered Lift document.
  • X identifies Basic Instrument Maneuvers, the Area of Operation.
  • F identifies Radio Communications, Navigation Systems/Facilities, and Radar Services, 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

Official ACS knowledge items and mock-oral treatment
ACS codeOfficial descriptionHow a mock oral can probe it
PL.X.F.K1Operating communications equipment, including identifying and selecting radio frequencies, requesting and following air traffic control (ATC) instructions.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
PL.X.F.K2Operating navigation equipment, including functions and displays, and following bearings, radials, or courses.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
PL.X.F.K3Air traffic control facilities and services.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.

Risk management elements

Official ACS risk management items and mock-oral treatment
ACS codeOfficial descriptionHow a mock oral can probe it
PL.X.F.R1When to seek assistance or declare an emergency in a deteriorating situation.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
PL.X.F.R2Using available resources (e.g., automation, ATC, and flight deck planning aids).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
PL.X.F.S1Maintain aircraft control while selecting proper communications frequencies, identifying the appropriate facility, and managing navigation equipment.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PL.X.F.S2Comply with ATC instructions.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.
