What is the document that prescribes air traffic phraseology and procedures?

The document that prescribes air traffic phraseology and procedures is indeed 7110.65. This manual, also known as the "Air Traffic Control" order, outlines the standard phraseology used by air traffic controllers when communicating with pilots and other controllers. This standardization is crucial for ensuring clarity and efficiency in communication, which directly contributes to the safety and effectiveness of air traffic management.

This document is essential for air traffic controllers as it provides guidelines for everything from the communication methods used in routine operations to emergency procedures. The emphasis on consistent phraseology helps minimize misunderstandings, thereby enhancing the overall safety of the aviation system.

The other documents listed, such as 7210.3, 7020.1, and 7070.1, serve different purposes within FAA regulations but do not specifically focus on the phraseology and procedures for air traffic control. For instance, 7210.3 deals more with the management and organization of air traffic services rather than the specific communications used by controllers.
