What document provides directives to FAA personnel on specific subjects and programs?

The FAA Order serves as a primary directive for FAA personnel, offering specific guidance on a wide range of subjects and programs within the Federal Aviation Administration. These orders are designed to ensure consistency and standardization in procedures, policies, and responsibilities across various divisions and operations of the FAA. They are essential for communicating established practices and are often updated to reflect new regulations, safety protocols, or organizational changes.

Other documents mentioned, such as the Federal Register, provide a public record of proposed and final regulations but do not directly serve as directives for FAA personnel. The Aviation Safety Manual focuses specifically on safety protocols but is not as comprehensive in covering all policies, and the Grant Assurance Document pertains specifically to obligations concerning federal funding for airport projects rather than general directives for FAA operations. Thus, the FAA Order stands out as the primary source for directives impacting operational procedures and personnel guidelines within the agency.
