## Official Task objective

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

## Knowledge elements

- **AI.XII.G.K1** — Factors affecting minimum controllable speed (VMC).
- **AI.XII.G.K2** — VMC (red line) and best single-engine rate of climb airspeed (VYSE) (blue line).
- **AI.XII.G.K3** — How to identify, verify, feather, and secure an inoperative engine.
- **AI.XII.G.K4** — Importance of drag reduction, including propeller feathering, gear and flap retraction, the manufacturer’s recommended control input and its relation to zero sideslip.
- **AI.XII.G.K5** — Applicant responsibilities during simulated feathering.
- **AI.XII.G.K6** — Common errors related to this Task.

## Risk management elements

- **AI.XII.G.R1** — Potential engine failure after in flight or during an approach.
- **AI.XII.G.R2** — Collision hazards.
- **AI.XII.G.R3** — Configuring the airplane.
- **AI.XII.G.R4** — Low altitude maneuvering, including stall, spin, or controlled flight into terrain (CFIT).
- **AI.XII.G.R5** — Distractions, task prioritization, loss of situational awareness, or disorientation.
- **AI.XII.G.R6** — Possible single-engine go-around.

## Skills elements

- **AI.XII.G.S1** — Promptly recognize an engine failure and maintain positive aircraft control.
- **AI.XII.G.S2** — Set the engine controls, reduce drag, identify and verify the inoperative engine, and simulate feathering of the propeller on the inoperative engine (evaluator should then establish zero thrust on the inoperative engine).
- **AI.XII.G.S3** — Follow the manufacturer’s recommended emergency procedures and complete the appropriate checklist.
- **AI.XII.G.S4** — Monitor the operating engine and aircraft systems and make adjustments as necessary.
- **AI.XII.G.S5** — Maintain the manufacturer's recommended approach airspeed ±5 knots in the landing configuration with a stabilized approach, until landing is assured.
- **AI.XII.G.S6** — Make smooth, timely, and correct control application before, during, and after touchdown.
- **AI.XII.G.S7** — Touch down on the first one-third of available runway/landing surface, with no drift, and the airplane’s longitudinal axis aligned with and over the runway center or landing path.
- **AI.XII.G.S8** — Maintain directional control and appropriate crosswind correction throughout the approach and landing.
- **AI.XII.G.S9** — Complete the appropriate checklist(s).
- **AI.XII.G.S10** — 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

- 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.
