What is the main function of the Code of Federal Regulations (CFR) in aviation?

The main function of the Code of Federal Regulations (CFR) in aviation is to provide safety rules for operations. The CFR encompasses a comprehensive set of federal regulations that govern various aspects of aviation safety, including aircraft maintenance, pilot qualifications, and operational procedures. By establishing these regulations, the CFR plays a crucial role in ensuring the safety and security of passengers and crew aboard commercial flights. It mandates compliance with safety standards that aviation professionals must adhere to in order to minimize risks and enhance overall operational safety.

Other options focus on different aspects of aviation but do not capture the primary purpose of the CFR. Company travel policies and flight crew training guidelines are typically governed by specific organizational standards, while airport traffic management falls under different regulatory frameworks. Thus, option B stands out as the primary objective of the CFR in the context of aviation safety.
