Official task objective
To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with recovering from unusual flight attitudes solely by reference to instruments.
What the ACS code means
- IP identifies the ACS standard family used for this Instrument Rating Powered Lift document.
- IV identifies Flight by Reference to Instruments, the Area of Operation.
- B identifies Recovery from Unusual Flight Attitudes, 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 |
|---|---|---|
| IP.IV.B.K1 | Prevention of unusual attitudes, including flight causal, physiological, and environmental factors, and system and equipment failures. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| IP.IV.B.K2 | Procedures for recovery from unusual attitudes in flight. | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| IP.IV.B.K3 | Procedures available to safely regain visual meteorological conditions (VMC) after flight into inadvertent instrument meteorological conditions or unintended instrument meteorological conditions (IIMC)/(UIMC). | Explain the element, apply it to a scenario, and connect the answer to current references or aircraft information when relevant. |
| IP.IV.B.K4 | Appropriate use of automation, if applicable. | 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 |
|---|---|---|
| IP.IV.B.R1 | Situations that could lead to loss of control in-flight (LOC-I) or unusual attitudes in-flight (e.g., stress, task saturation, inadequate instrument scan distractions, and spatial disorientation). | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IP.IV.B.R2 | Assessment of the unusual attitude. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IP.IV.B.R3 | Control input errors, inducing undesired aircraft attitudes. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IP.IV.B.R4 | Collision hazards. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IP.IV.B.R5 | 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. |
| IP.IV.B.R6 | Interpreting flight instruments. | Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision. |
| IP.IV.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. |
| IP.IV.B.R8 | Operating envelope considerations. | 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 |
|---|---|---|
| IP.IV.B.S1 | Use proper instrument cross-check and interpretation to identify an unusual attitude (including both nose-high and nose-low) in flight, and apply the appropriate flight control, power input, and aircraft configuration in the correct sequence, to return to a stabilized level flight attitude. | Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test. |
| IP.IV.B.S2 | 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
- See 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.
