What is the document that lists location identifiers authorized by the FAA?

The document that lists location identifiers authorized by the FAA is indeed 7350.9. This order is specifically dedicated to providing a comprehensive list of location identifiers, which are crucial for communication and navigation in the National Airspace System. It serves as an official reference for pilots, air traffic controllers, and other aviation professionals who need to use these identifiers for flight operations, planning, and management.

The other options, while they pertain to aviation and air traffic control, serve different purposes. For instance, 7210.3 outlines air traffic control procedures and responsibilities but does not focus exclusively on location identifiers. The Aeronautical Information Manual provides broad guidelines and information about flight operations and procedures in the United States, without being a specific list of identifiers. Order 8900.1 is a comprehensive document that contains guidance on various regulatory and procedural standards but does not specifically serve as the official list of location identifiers either. Hence, the selection of 7350.9 is accurate as it fulfills the specific need for location identifier references.
