Federal Aviation Regulations Practice Test 2026 – Complete Exam Prep

The part of the Federal Aviation Regulations (FAR) that outlines requirements for air carrier operations is indeed Part 121. This section specifically addresses the regulations governing scheduled air carriers and charter services, which include operational, maintenance, and management standards necessary for safety and efficiency in commercial aviation.

Part 121 encompasses detailed requirements concerning crew qualifications, aircraft maintenance, and operational procedures that air carriers must adhere to in order to ensure compliance with safety standards. This ensures that air carriers can operate safely and efficiently, protecting both passengers and cargo during flight operations.

In contrast, other parts such as Part 61 focus on pilot certifications and training, Part 135 deals with commuter and on-demand operations (which can include smaller commercial services), and Part 91 governs general aviation operations, which are not classified under commercial air carrier regulations. Therefore, the focus and stipulations outlined in Part 121 specifically cater to the needs and requirements of scheduled air carriers.
