Operating rules for General Aviation flights are found in which FAR part?

Operating rules for General Aviation flights are outlined in FAR Part 91. This part of the Federal Aviation Regulations (FAR) covers a broad range of operational guidelines that apply specifically to pilots and aircraft operators in the general aviation sector. It includes regulations regarding the operation of aircraft, pilot certification, aircraft maintenance, and other essential requirements for safe flying.

General aviation encompasses a wide array of flying activities outside of scheduled airline services, which means that Part 91 provides the fundamental operational framework for non-commercial and private flights. This ensures that pilots and operators adhere to safety standards and regulations critical for maintaining safe flight operations.

Other parts mentioned in the options pertain to different aspects of aviation. FAR Part 63 deals with the certification of flight crew members other than pilots, Part 65 pertains to certification of personnel other than pilot, such as air traffic controllers, and Part 121 is focused on the operating requirements for domestic, flag, and supplemental operations of US air carriers. Thus, these parts do not govern general aviation operations in the same way that Part 91 does.
