Federal Aviation Regulations Practice Test 2026 – Complete Exam Prep

Part 139 of the Federal Aviation Regulations (FAR) specifically governs airport operations, particularly those related to the certification of airports that serve scheduled air carriers. This part outlines the requirements for facilities, equipment, and services that airports must maintain to ensure safe and efficient operations. It includes standards for runway conditions, safety management systems, and airport personnel training, among other operational requirements.

In contrast, other parts of the FAR cover different aspects of aviation regulation. For instance, Part 91 deals primarily with general operating and flight rules applicable to all aircraft, while Part 61 is focused on the certification of pilots, flight instructors, and ground instructors. Part 23 pertains to airworthiness standards for small aircraft, which is also outside the scope of airport operations.

The specific focus of Part 139 on the safety and operational standards necessary for airports that handle passenger and cargo flights makes it the correct answer for governing airport operations.
