Which regulation outlines the least restrictive policies in aviation?

The Code of Federal Regulations, specifically Title 14, outlines the Federal Aviation Regulations (FAR), which are designed to govern all aspects of civil aviation in the United States. This regulation includes standards for safety protocols, operational requirements, and certification processes, ensuring a baseline for safety practices across various aviation activities. FAR represents the least restrictive policies in aviation because it serves as the foundational legal framework within which other policies and operational guidelines can be developed and established.

Unlike the other options, which often pertain to specific agencies or projects with potentially more prescriptive or specialized requirements, the FAR allows for flexibility in compliance as long as the minimum safety standards are met. This adaptability enables aviation organizations to tailor their operations while still adhering to essential federal safety standards, reflecting the fundamental principle of promoting safety without imposing overly burdensome regulations. Thus, the FAR is recognized as the regulatory backbone that balances necessary safety measures with operational flexibility in the aviation sector.
