Official task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with stalls in the landing configuration

What the ACS code means

  • AA identifies the ACS standard family used for this Airline Transport Pilot Airplane document.
  • V identifies Stall Prevention, the Area of Operation.
  • C identifies Landing Configuration Stall Prevention, 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
AA.V.C.K1Aerodynamics associated with stalls in the landing configuration, including the relationship between angle of attack, airspeed, load factor, power setting, aircraft weight and balance, aircraft attitude, and sideslip effects.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
AA.V.C.K2Stall characteristics as they relate to airplane design, and recognition impending stall and full stall indications using sight, sound, or feel.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
AA.V.C.K3Factors and situations that can lead to a stall when configured for landing and actions that can be taken to prevent it.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
AA.V.C.K4Effects of autoflight, flight envelope protection in normal and degraded modes, and unexpected disconnects of the autopilot or autothrottle/autothrust, if applicable to the aircraft used for the evaluation.Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant.
AA.V.C.K5Fundamentals of stall recovery.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
AA.V.C.R1Factors and situations that could lead to an inadvertent stall, spin, and loss of control during landing.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
AA.V.C.R2Range and limitations of stall warning indicators (e.g., aircraft buffet, stall horn, stick shaker, etc.).Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
AA.V.C.R3Stall warning awareness.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.

AA.V.C.R5Secondary stalls, accelerated stalls, elevator trim stalls, and cross-control stalls.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
AA.V.C.R6Effect of environmental elements on aircraft performance while landing as it relates to stalls (e.g., turbulence, icing, microbursts, and high-density altitude).Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
AA.V.C.R7Stalls at a low altitude.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
AA.V.C.R8Collision hazards, including aircraft and terrain.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
AA.V.C.S1Clear the area and select an entry altitude that allows the recovery to be completed no lower than 3,000 feet above ground level (AGL) (non-transport category airplanes) or 5,000 feet AGL (transport category airplanes).Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.V.C.S2[Archived]Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.V.C.S3Establish the landing configuration (i.e., lift/drag devices set and landing gear extended) and maintain coordinated flight in simulated or actual instrument conditions 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.
AA.V.C.S4Either manually or with the autopilot engaged, smoothly adjust pitch attitude, bank angle (15°-30°), and power setting in accordance with evaluator’s instructions to an impending stall.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.V.C.S5Acknowledge the cue(s) and promptly recover at the first indication of an impending stall (e.g., buffet, stall horn, stick shaker, etc.).Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.V.C.S6Execute a stall recovery in accordance with procedures set forth in the Pilot's Operating Handbook (POH)/Flight Manual (FM).Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
AA.V.C.S7Retract the flaps or other lift/drag devices to the recommended setting, if applicable; retract the landing gear after a positive rate of climb is established, if applicable; and return to the desired flight path as specified 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.

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.
