The Instrument Rating Practical Test Standards (PTS) book is
published by the Federal Aviation Administration (FAA) to establish
the standards for instrument rating certification practical tests for the
airplane, helicopter, and powered lift, category and classes. These
practical test standards shall also be used for the instrument portion
of the Commercial Pilot-Airship practical test. FAA inspectors and
designated pilot examiners shall conduct practical tests in
compliance with these standards. Flight instructors and applicants
should find these standards helpful during training and when
preparing for practical tests.
