Federal Aviation Regulations Practice Test 2025 – Complete Exam Prep

Part 91 of the Federal Aviation Regulations (FAR) indeed covers general operating and flight rules. This part is crucial because it establishes the baseline regulations under which all pilots operate. It provides extensive guidance on how aircraft should be operated safely in U.S. airspace, including requirements for pre-flight actions, flight operations during day and night, and rules for various types of special operations.

For instance, Part 91 contains regulations regarding the use of airspace, equipment requirements, and the responsibilities of the pilot in command. It also includes rules on maintenance responsibilities, handling of in-flight emergencies, and the operation of aircraft within visual flight rules (VFR) and instrument flight rules (IFR).

The other parts mentioned pertain to different areas of aviation: Part 61 deals with certification of pilots and flight instructors, Part 139 covers certification of airports and the management of airport operations related to commercial air transport, while Part 23 focuses on airworthiness standards for normal, utility, acrobatic, and commuter category airplanes. Each part serves a specific function in aviation regulation, but it is Part 91 that governs the general operating rules applicable to all flights.
