Official task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with executing a published instrument approach solely by reference to instruments with one engine inoperative.

What the ACS code means

  • IH identifies the ACS standard family used for this Instrument Rating Rotorcraft document.
  • VII identifies Emergency Operations, the Area of Operation.
  • B identifies Instrument Approach and Landing with an Inoperative Engine (Simulated) (Multiengine Helicopter Only), 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
IH.VII.B.K1Instrument approach procedures with one engine inoperative.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
IH.VII.B.R1Potential engine failure during approach and landing.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
IH.VII.B.R2Aircraft/powerplant limitations.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
IH.VII.B.R3Distractions, 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.
IH.VII.B.R4Collision hazards.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
IH.VII.B.R5Configuring the helicopter.Work through a scenario by identifying the hazard, evaluating the risk, and explaining a practical mitigation or decision.
IH.VII.B.R6Performing a go-around/rejected landing with an engine failure.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

IH.VII.B.S2Use flight controls and configure the helicopter as required to maintain best performance or as recommended by the manufacturer.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
IH.VII.B.S3Follow the manufacturer’s recommended emergency procedures and complete the appropriate checklist.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
IH.VII.B.S4Maintain control and fly the helicopter within the one engine inoperative (OEI) operating limitations.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
IH.VII.B.S5Monitor the operating engine and helicopter systems and make adjustments as necessary.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
IH.VII.B.S6Request and follow an actual or a simulated air traffic control (ATC) clearance for an instrument approach.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
IH.VII.B.S7Maintain altitude ±100 feet, airspeed ±10 knots, and selected heading ±10°.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
IH.VII.B.S8Establish a rate of descent that ensures arrival at the minimum descent altitude (MDA) or decision altitude (DA)/decision height (DH) with the helicopter in a position from which a descent to the intended runway or other landing point can be made.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
IH.VII.B.S9On final approach segment, maintain vertical (as applicable) and lateral guidance within ¾-scale deflection.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
IH.VII.B.S10Execute a landing.Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
IH.VII.B.S11Complete the appropriate checklist(s).Describe the procedure, interpretation, or decision process that can be discussed during an oral. Physical aircraft performance remains part of the practical test.
IH.VII.B.S12Use 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

  • Note: 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.
