Official task objective
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with accelerated stalls (power-on or power-off).
What the ACS code means
- CA identifies the ACS standard family used for this Commercial Pilot Airplane document.
- VII identifies Slow Flight and Stalls, the Area of Operation.
- D identifies Accelerated Stalls, 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
| ACS code | Official description | How a mock oral can probe it |
|---|---|---|
| CA.VII.D.K1 | Aerodynamics associated with accelerated stalls in various airplane configurations, including the relationship between angle of attack, airspeed, load factor, power setting, airplane weight and center of gravity, airplane attitude, and yaw effects. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| CA.VII.D.K2 | Stall 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. |
| CA.VII.D.K3 | Factors leading to an accelerated stall and preventive actions. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| CA.VII.D.K4 | Fundamentals 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
| ACS code | Official description | How a mock oral can probe it |
|---|---|---|
| CA.VII.D.R1 | Factors and situations that could lead to an inadvertent accelerated stall, spin, and loss of control. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| CA.VII.D.R2 | Range and limitations of stall warning indicators (e.g., aircraft buffet, stall horn, etc.). | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| CA.VII.D.R3 | Stall warning(s) during normal operations. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| CA.VII.D.R4 | Stall recovery procedure. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| CA.VII.D.R5 | Secondary stalls, cross-control stalls, and spins. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| CA.VII.D.R6 | Effect of environmental elements on airplane performance related to accelerated stalls (e.g., turbulence, microbursts, and high-density altitude). | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| CA.VII.D.R7 | Collision hazards. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| CA.VII.D.R8 | Distractions, task prioritization, loss of situational awareness, or disorientation. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
Skills elements
| ACS code | Official description | How a mock oral can probe it |
|---|---|---|
| CA.VII.D.S1 | Clear the area. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.VII.D.S2 | Select an entry altitude that allows the Task to be completed no lower than 3,000 feet above ground level (AGL). | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.VII.D.S3 | Establish the configuration 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. |
| CA.VII.D.S4 | Set power appropriate for the configuration, such that the airspeed does not exceed the maneuvering speed (VA) or any other applicable Pilot's Operating Handbook (POH)/Airplane Flight Manual (AFM) limitation. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.VII.D.S5 | Establish and maintain a coordinated turn in a 45° bank, increasing elevator back pressure smoothly and firmly until an impending stall is reached. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.VII.D.S6 | Acknowledge the cues at the first indication of a stall (e.g., aircraft buffet, stall horn, etc.). | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.VII.D.S7 | Execute 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. |
| CA.VII.D.S8 | Configure the airplane as recommended by the manufacturer, and accelerate to best angle of climb speed (VX) or best rate of climb speed (VY). | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| CA.VII.D.S9 | Return to the altitude, heading, and airspeed 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.
