Official task objective
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with power-on stalls.
What the ACS code means
- PA identifies the ACS standard family used for this Private Pilot Airplane document.
- VII identifies Slow Flight and Stalls, the Area of Operation.
- C identifies Power-On 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

|---|---|---|
| PA.VII.C.K1 | Aerodynamics associated with 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. |
| PA.VII.C.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. |
| PA.VII.C.K3 | Factors and situations that can lead to a power-on stall 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. |
| PA.VII.C.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 |
|---|---|---|

| PA.VII.C.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. |
| PA.VII.C.R4 | Stall recovery procedure. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| PA.VII.C.R5 | Secondary 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. |
| PA.VII.C.R6 | Effect of environmental elements on airplane performance related to power-on 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. |
| PA.VII.C.R7 | Collision hazards. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| PA.VII.C.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 |
|---|---|---|
| PA.VII.C.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. |
| PA.VII.C.S2 | Select an entry altitude that allows the Task to be completed no lower than 1,500 feet above ground level (AGL) (ASEL, ASES) or 3,000 feet AGL (AMEL, AMES). | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.VII.C.S3 | Establish the takeoff, departure, or cruise configuration, as specified by the evaluator, and maintain coordinated flight 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. |
| PA.VII.C.S4 | Set power (as assigned by the evaluator) to no less than 65 percent power. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.VII.C.S5 | Transition smoothly from the takeoff or departure attitude to the pitch attitude that induces a stall. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.VII.C.S6 | Maintain a specified heading, ±10° if in straight flight; maintain a specified angle of bank not to exceed 20°, ±10° if in turning flight, while inducing the stall. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.VII.C.S7 | Acknowledge cues of the impending stall and then recover promptly after a full stall occurs. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PA.VII.C.S8 | 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. |
| PA.VII.C.S9 | 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. |
| PA.VII.C.S10 | 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. |
| PA.VII.C.S11 | Use 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

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.
