## Official Task objective

To determine the applicant understands approach and landing with one engine inoperative (OEI) (simulated), can apply that knowledge, manage associated risks, demonstrate appropriate skills, and provide effective instruction.

## Knowledge elements

- **HI.XI.C.K1** — Elements of approach and landing with one engine inoperative.
- **HI.XI.C.K2** — Effects of atmospheric conditions on emergency approach and landing.
- **HI.XI.C.K3** — Stabilized approach.
- **HI.XI.C.K4** — Approach and landing profiles and aircraft configuration.
- **HI.XI.C.K5** — Common errors related to this Task.

## Risk management elements

- **HI.XI.C.R1** — Consideration of altitude, wind, terrain, obstructions, and available landing area.
- **HI.XI.C.R2** — Planning and following a flightpath to the selected landing area.
- **HI.XI.C.R3** — Collision hazards.
- **HI.XI.C.R4** — Distractions, task prioritization, loss of situational awareness, or disorientation.

## Skills elements

- **HI.XI.C.S1** — Maintain the operating powerplant within OEI limits.
- **HI.XI.C.S2** — Maintain, prior to beginning the final approach segment, the recommended flight profile with altitude ±100 feet, airspeed, ±10 knots, heading ±5°, and maintains track.
- **HI.XI.C.S3** — Make radio calls as appropriate.
- **HI.XI.C.S4** — Plan and follow a flightpath to the selected landing area considering altitude, wind, terrain, and obstructions.
- **HI.XI.C.S5** — Complete the appropriate checklist(s).
- **HI.XI.C.S6** — Maintain directional control and appropriate crosswind correction throughout the approach and landing.
- **HI.XI.C.S7** — Use single-pilot resource management (SRM) or crew resource management (CRM), as appropriate.
- **HI.XI.C.S8** — Analyze and correct common errors related to this Task.

## 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.
