What primary function do the rules outlined in CFR 14 serve?

The primary function of the rules outlined in CFR 14, which is part of the Code of Federal Regulations, is to set regulations for aeronautics and space. This part of the regulations includes comprehensive guidelines that cover various aspects of aviation, including the operation of aircraft, safety standards, and certification processes. CFR 14 specifically addresses the Federal Aviation Administration's (FAA) regulations that govern how the aviation industry operates within the United States, ensuring that both commercial and private aviation adhere to established safety and operational standards. This regulatory framework is essential for maintaining safe airspace and the overall integrity of the aviation system.

While the other options may involve aspects of aviation, such as maintenance procedures, flight guidelines, and insurance requirements, they do not encapsulate the broad regulatory focus of CFR 14, which encompasses a wide range of regulations impacting all forms of aeronautics and their operational standards.
