What does the term "CFR" stand for in aviation regulations?

The term "CFR" refers to the Code of Federal Regulations. In the context of aviation, the CFR is essential as it encompasses the rules and regulations created by federal agencies, including the Federal Aviation Administration (FAA). These regulations govern all aspects of civil aviation in the United States, providing guidelines for pilots, maintenance standards, air traffic procedures, and much more, ensuring safety and compliance across the industry.

Understanding the CFR is critical for pilots, as it outlines the legal framework within which they operate. For example, Part 14 of the CFR deals specifically with the Federal Aviation Regulations (FAR), which governs aspects of flight rules, pilot certification, and other operational standards necessary for safe flight operations.

While other choices may contain elements that suggest regulatory frameworks, they do not accurately represent the full and correct terminology used in U.S. federal law. The Code of Federal Regulations is a comprehensive and established source of legal standards, making it the correct answer in this context.
