Official task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with engine failure after liftoff.

What the ACS code means

  • PA identifies the ACS standard family used for this Private Pilot Airplane document.
  • IX identifies Emergency Operations, the Area of Operation.
  • F identifies Engine Failure After Liftoff (Simulated) (AMEL, AMES), 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
PA.IX.F.S1Promptly recognize an engine failure, maintain control, and use appropriate emergency procedures.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PA.IX.F.S2Establish VYSE; if obstructions are present, establish best single-engine angle of climb speed (VXSE) or VMC +5 knots, whichever is greater, until obstructions are cleared. Then transition to VYSE.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PA.IX.F.S3Reduce drag by retracting landing gear and flaps in accordance with the manufacturer’s guidance.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PA.IX.F.S4Simulate feathering the propeller on the inoperative engine (evaluator should then establish zero thrust on the inoperative engine).Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PA.IX.F.S5Use flight controls in the proper combination 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.
PA.IX.F.S6Monitor the operating engine and aircraft systems and make adjustments as necessary.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PA.IX.F.S7Recognize the airplane’s performance capabilities. If a climb is not possible at VYSE, maintain VYSE and return to the departure airport for landing, or initiate an approach to the most suitable landing area available.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PA.IX.F.S8Simulate securing the inoperative engine.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PA.IX.F.S9Maintain heading ±10° and airspeed ±5 knots.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
PA.IX.F.S10Complete 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.

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.

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.
