What is the codification of the general and permanent rules established by the U.S. Government?

The codification of the general and permanent rules established by the U.S. Government is best represented by the Code of Federal Regulations (CFR). The CFR is a comprehensive collection of all federal regulations, organized by subject and published annually. It serves as a systematic resource for individuals and organizations looking to understand and comply with federal rules, policies, and guidelines across various domains, including health, safety, and environmental protections.

In contrast, Federal Aviation Regulations are specific to the aviation sector, detailing rules that govern civil aviation. While they are indeed part of the broader regulatory framework, they do not encompass all federal regulations. Similarly, ATA Chapters and ICAO annexes relate to aviation standards and international guidelines, respectively, but they are not codifications of U.S. federal regulations. Therefore, the Code of Federal Regulations stands out as the correct and comprehensive source for U.S. government's general and permanent rules.
