## 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.

## Knowledge elements

- **IH.VII.B.K1** — Instrument approach procedures with one engine inoperative.

## Risk management elements

- **IH.VII.B.R1** — Potential engine failure during approach and landing.
- **IH.VII.B.R2** — Aircraft/powerplant limitations.
- **IH.VII.B.R3** — Distractions, task prioritization, loss of situational awareness, or disorientation.
- **IH.VII.B.R4** — Collision hazards.
- **IH.VII.B.R5** — Configuring the helicopter.
- **IH.VII.B.R6** — Performing a go-around/rejected landing with an engine failure.

## Skills elements

- **IH.VII.B.S1** — Promptly recognize an engine failure and maintain positive helicopter control.
- **IH.VII.B.S2** — Use flight controls and configure the helicopter as required to maintain best performance or as recommended by the manufacturer.
- **IH.VII.B.S3** — Follow the manufacturer’s recommended emergency procedures and complete the appropriate checklist.
- **IH.VII.B.S4** — Maintain control and fly the helicopter within the one engine inoperative (OEI) operating limitations.
- **IH.VII.B.S5** — Monitor the operating engine and helicopter systems and make adjustments as necessary.
- **IH.VII.B.S6** — Request and follow an actual or a simulated air traffic control (ATC) clearance for an instrument approach.
- **IH.VII.B.S7** — Maintain altitude ±100 feet, airspeed ±10 knots, and selected heading ±10°.
- **IH.VII.B.S8** — Establish 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.
- **IH.VII.B.S9** — On final approach segment, maintain vertical (as applicable) and lateral guidance within ¾-scale deflection.
- **IH.VII.B.S10** — Execute a landing.
- **IH.VII.B.S11** — Complete the appropriate checklist(s).
- **IH.VII.B.S12** — Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.

## Difficulty methodology

Difficulty calibration is ongoing for this Task. Observed difficulty is a privacy-thresholded check-ride.ai mock-oral practice proxy, not an FAA practical-test pass or fail rate. Underlying sample sizes and the private reporting threshold are not published.

## 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.

## Use in practice

A mock examiner can ask a pilot to explain the published elements, apply them to the configured aircraft and airport context, identify risks, and defend a decision. Practice prompts are not represented as actual FAA examiner scripts or predictions of the questions a candidate will receive.
