What does the acronym CFR stand for in aviation regulations?

The acronym CFR stands for Code of Federal Regulations. This is a crucial term in aviation and other fields, as it represents the codification of the general and permanent rules published in the Federal Register by the executive departments and agencies of the United States federal government. In the context of aviation, the CFR includes regulations established by the Federal Aviation Administration (FAA) that govern various aspects of aviation safety, security, operation of unmanned aircraft systems (UAS), and many other regulations affecting aviation operations. Understanding CFR is essential for anyone involved in aviation, including pilots, operators, and regulatory personnel, because it contains the legal guidelines and rules they must follow to operate safely and legally within the aviation framework.
