Which document contains regulations for operational procedures and practices in air traffic control?

The Aeronautical Information Manual (AIM) serves as a comprehensive resource that encompasses regulations, practices, and procedures vital for operation within the air traffic control system. It provides essential information about air navigation, flight safety, and the responsibilities of various parties in the aviation environment, including pilots, air traffic controllers, and other personnel involved in aviation operations. The AIM is published by the Federal Aviation Administration (FAA) and is regularly updated to reflect the latest regulations, guidance, and changes in operational procedures.

In contrast, while the Federal Aviation Regulations (FAR) do cover a wide range of aviation rules, they primarily focus on the regulatory framework rather than the specific operational guidelines. The Air Traffic Control Handbook typically refers to internal documents used by the FAA and may not be accessible or applicable to the public or all stakeholders in aviation. The Flight Procedures Manual often addresses specific flight procedures but may not cover the broader operational practices and regulatory information that the AIM provides. Thus, the AIM is the most appropriate choice for regulations regarding operational procedures and practices in air traffic control.
