## Official Task objective

To determine the applicant understands attitude instrument flying during constant airspeed climbs, can apply that knowledge, manage associated risks, demonstrate appropriate skills, and provide effective instruction, solely by reference to instruments.

## Knowledge elements

- **AI.XI.B.K1** — Flight instruments as they relate to:
- **AI.XI.B.K1a** — a. Instrument limitations and potential errors
- **AI.XI.B.K1b** — b. Indication of the aircraft attitude
- **AI.XI.B.K1c** — c. Function and operation
- **AI.XI.B.K1d** — d. Proper instrument cross-check techniques
- **AI.XI.B.K2** — Common errors related to this Task.

## Risk management elements

- **AI.XI.B.R1** — Instrument flying hazards, including failure to maintain visual flight rules (VFR), spatial disorientation, loss of control, fatigue, stress, and emergency off airport landings.
- **AI.XI.B.R2** — When to seek assistance or declare an emergency in a deteriorating situation.
- **AI.XI.B.R3** — Collision hazards.
- **AI.XI.B.R4** — Distractions, task prioritization, loss of situational awareness, or disorientation.
- **AI.XI.B.R5** — Fixation and omission.
- **AI.XI.B.R6** — Instrument Interpretation.
- **AI.XI.B.R7** — Control application solely by reference to instruments.
- **AI.XI.B.R8** — Trimming the aircraft.

## Skills elements

- **AI.XI.B.S1** — Transition to the climb pitch attitude and power setting on an assigned heading using proper instrument cross-check and interpretation, and coordinated flight control application.
- **AI.XI.B.S2** — Climb at a constant airspeed to specific altitudes in straight flight and turns.
- **AI.XI.B.S3** — Level off at the assigned altitude and maintain altitude ±100 feet, heading ±10°, and airspeed ±10 knots.
- **AI.XI.B.S4** — 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.

## 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.
