What document outlines the procedures and rules for airspace use in the U.S.?

The Aeronautical Information Manual (AIM) serves as the primary resource that outlines the procedures and rules for airspace use in the United States. It is designed to provide essential information for pilots and other aviation personnel to help them understand the operational, procedural, and regulatory frameworks governing air navigation.

The AIM is comprehensive and covers topics such as air traffic control procedures, navigation methods, and communication protocols relevant to maintaining safety in U.S. airspace. This manual is updated regularly to reflect changes in regulations and best practices, ensuring that users have the most current and relevant information.

While other documents may include relevant information about airspace, such as the FAA Regulations Handbook or the National Airspace System (NAS) Guide, they do not specifically serve the same purpose as the AIM in providing a clear and comprehensive overview of airspace procedures and rules. The Flight Operations Manual typically relates to specific operators and their internal procedures, rather than government-wide regulations and guidelines applicable to all aviators.
