## Official Task objective

To determine the applicant exhibits satisfactory knowledge, risk management, and skills associated with
IFR departure, en route, and arrival operations solely by reference to instruments.

## Knowledge elements

- **IR.V.B.K1** — Elements related to ATC routes, including departure procedures (DPs) and associated climb gradients;
standard terminal arrival (STAR) procedures and associated constraints.
- **IR.V.B.K2** — Pilot/controller responsibilities, communication procedures, and ATC services available to pilots.

## Risk management elements

- **IR.V.B.R1** — ATC communications and compliance with published procedures.
- **IR.V.B.R2** — Limitations of traffic avoidance equipment.
- **IR.V.B.R3** — Responsibility to use "see and avoid" techniques when possible.

## Skills elements

- **IR.V.B.S1** — Select, identify (as necessary) and use the appropriate communication and navigation facilities
associated with the proposed flight.
- **IR.V.B.S2** — Perform the appropriate checklist items relative to the phase of flight.
- **IR.V.B.S3** — Use the current and appropriate paper or electronic navigation publications.
- **IR.V.B.S4** — Establish two-way communications with the proper controlling agency, use proper phraseology, and
comply in a timely manner with all ATC instructions and airspace restrictions.
- **IR.V.B.S5** — Intercept all courses, radials, and bearings appropriate to the procedure, route, or clearance in a timely
manner.
- **IR.V.B.S6** — Comply with all applicable charted procedures.
- **IR.V.B.S7** — Maintain airspeed ±10 knots, altitude ±100 feet, and selected headings ±10°, and apply proper
correction to maintain a course allowing no more than ¾-scale deflection of the course deviation
indicator (CDI).
- **IR.V.B.S8** — Update/interpret weather in flight.
- **IR.V.B.S9** — Use displays of digital weather and aeronautical information, as applicable to maintain situational
awareness.
- **IR.V.B.S10** — 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.

## 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.
