Official task objective
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with attitude instrument flying during constant airspeed climbs solely by reference to instruments.
What the ACS code means
- PL identifies the ACS standard family used for this Private Pilot Powered Lift document.
- X identifies Basic Instrument Maneuvers, the Area of Operation.
- B identifies Constant Airspeed Climbs, 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 |
|---|---|---|
| PL.X.B.K1 | Flight instruments as they relate to: | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| PL.X.B.K2a | a. Instrument limitations and potential errors | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| PL.X.B.K2b | b. Indication of the aircraft attitude | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| PL.X.B.K2c | c. Function and operation | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| PL.X.B.K2d | d. Proper instrument cross-check techniques | 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 |
|---|---|---|
| PL.X.B.R1 | Instrument flying hazards, including failure to maintain visual flight rules (VFR), spatial disorientation, loss of control, fatigue, stress, and emergency off airport landings. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| PL.X.B.R2 | When to seek assistance or declare an emergency in a deteriorating situation. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| PL.X.B.R3 | Collision hazards. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| PL.X.B.R4 | 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. |
| PL.X.B.R5 | Fixation and omission. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| PL.X.B.R6 | Instrument Interpretation. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| PL.X.B.R7 | Control application solely by reference to instruments. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| PL.X.B.R8 | Trimming the aircraft. | 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 |
|---|---|---|
| PL.X.B.S1 | Transition to the climb pitch attitude and power setting on an assigned heading using proper instrument cross-check and interpretation, and coordinated flight control application. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PL.X.B.S2 | Climb at a constant airspeed to specific altitudes in straight flight and turns. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| PL.X.B.S3 | Level off at the assigned altitude and maintain altitude ±200 feet, heading ±20°, and airspeed ±10 knots. | 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.
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.
