## Official Task objective

To determine the applicant understands attitude instrument flying during straight-and-level flight, can apply that knowledge, manage associated risks, demonstrate appropriate skills, and provide effective instruction

## Knowledge elements

- **PI.VI.A.K1** — Elements related to attitude instrument flying during straight-and-level flight.
- **PI.VI.A.K2** — The relationship of pitch, bank, power, and configuration in straight-and-level flight.
- **PI.VI.A.K3** — Interpretation, operation, and limitations of pitch, bank, and power instruments, using full panel and partial panel.
- **PI.VI.A.K4** — Normal and abnormal instrument indications, interpretations, and operations.
- **PI.VI.A.K5** — Instrument cross-check techniques.
- **PI.VI.A.K6** — Common errors related to this Task.

## Risk management elements

- **PI.VI.A.R1** — Fixation and omission.
- **PI.VI.A.R2** — Instrument Interpretation.
- **PI.VI.A.R3** — Control application solely by reference to instruments.
- **PI.VI.A.R4** — Aircraft coordination.
- **PI.VI.A.R5** — Situations that can affect physiology and degrade instrument cross-check.
- **PI.VI.A.R6** — Flying unfamiliar aircraft or operating with unfamiliar flight display systems and avionics.
- **PI.VI.A.R7** — Distractions, task prioritization, loss of situational awareness, or disorientation.

## Skills elements

- **PI.VI.A.S1** — Use proper instrument cross-check and interpretation, and apply the appropriate pitch, bank, power, configuration, and trim corrections when applicable.
- **PI.VI.A.S2** — Maintain straight-and-level flight using instrument cross-check and interpretation and coordinated control application.
- **PI.VI.A.S3** — Maintain altitude ±100 feet, heading ±10°, and airspeed ±10 knots.
- **PI.VI.A.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.
