Instrument Rating Airman Certification Standards
The Instrument Rating ACS replaces the Instrument Rating Practical Test Standards. The ACS framework provides a singleýsource explanation of standards for both the knowledge test and the practical test. It also enables the FAA to keep standards aligned with guidance (handbooks) and knowledge test questions. Built on the Practical Test Standards (PTS), the ACS adds the aeronautical knowledge and risk management elements needed to support each PTS Task. The ACS provides a clear, easy-to-use flight plan for the material the FAA expects an applicant to know (knowledge), consider (risk management), and do (skill) to qualify for an airman certificate or rating.
