The Instrument ACS is the FAA’s official standard for the Instrument Rating checkride and written test. It defines the exact knowledge, risk management, and skill elements you’ll be tested on, ensuring that instrument pilots are evaluated not only on precision flying but also on sound decision-making under IFR.
The document covers all phases of instrument flying, including preflight preparation, instrument departures, enroute procedures, holding, instrument approaches, partial-panel scenarios, and emergency operations. Each task clearly outlines tolerances and examiner expectations so you know exactly what to practice.
