Official task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with indications and pilot actions after powerplant(s) failure during takeoff while the aircraft is predominantly in thrust-borne flight in a multi-powerplant aircraft.

What the ACS code means

  • PL identifies the ACS standard family used for this Private Pilot Powered Lift document.
  • XI identifies Emergency Operations, the Area of Operation.
  • A identifies Powerplant(s) Failure (Simulated) during Takeoff in Thrust-Borne 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.

Skills elements

Official ACS skills items and mock-oral treatment
ACS codeOfficial descriptionHow a mock oral can probe it
PL.XI.A.S1Recognize that a powerplant(s) failure has occurred.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PL.XI.A.S2Use flight controls in the proper combination and aircraft configuration as recommended by the manufacturer, or as required to maintain best performance, and trim as required.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PL.XI.A.S3Maintain the operating powerplant(s) within acceptable operating limits.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PL.XI.A.S4Land the aircraft, as appropriate to the scenario presented by the evaluator.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PL.XI.A.S5Complete the appropriate checklist(s).Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PL.XI.A.S6Make radio calls 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.
PL.XI.A.S7Use 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.

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.

Official task notes

  • See Appendix 2: Safety of Flight and Appendix 3: Aircraft, Equipment, and Operational Requirements & Limitations for information related to this Task.
  • The task outcome can be vertical or rolling depending on aircraft capabilities, configuration, and flight manual procedures.

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.
