## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with diversion.

## Knowledge elements

- **CA.VI.C.K1** — Selecting an alternate destination.
- **CA.VI.C.K2** — Situations that require deviations from flight plan or air traffic control (ATC) instructions.

## Risk management elements

- **CA.VI.C.R1** — Collision hazards.
- **CA.VI.C.R2** — Distractions, task prioritization, loss of situational awareness, or disorientation.
- **CA.VI.C.R3** — Circumstances that would make diversion prudent.
- **CA.VI.C.R4** — Selecting an appropriate airport or seaplane base.
- **CA.VI.C.R5** — Using available resources (e.g., automation, ATC, and flight deck planning aids).

## Skills elements

- **CA.VI.C.S1** — Select a suitable destination and route for diversion.
- **CA.VI.C.S2** — Make a reasonable estimate of heading, groundspeed, arrival time, and fuel required to the “divert to” destination.
- **CA.VI.C.S3** — Maintain the appropriate altitude, ±100 feet and heading, ±10°.
- **CA.VI.C.S4** — Update/interpret weather in flight.
- **CA.VI.C.S5** — Use displays of digital weather and aeronautical information, as applicable to maintain situational awareness.
- **CA.VI.C.S6** — Promptly divert toward the destination.

## 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.

## 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.
