What guide dictates the procedures for managing air traffic control operations?

The correct answer focuses on Order 7210.3, which is the FAA order that outlines the procedures for managing air traffic control operations. This document provides essential guidelines that air traffic controllers must follow to ensure the safe and efficient flow of air traffic within controlled airspace. It includes instructions on various aspects of operations, including controller roles, traffic management practices, coordination with other agencies, and emergency procedures.

While the other options mentioned are important documents within the Federal Aviation Administration's system, they serve different purposes. For instance, FAA Handbook 8900.1 provides comprehensive guidance for the inspection and certification of aviation programs but does not specifically focus on air traffic control procedures. Order 7350.9 relates to airport and spacing procedures but is not a primary guide for air traffic control operations. The Air Traffic Service Manual outlines broader air traffic service policies but lacks the detailed procedural focus found in Order 7210.3. Therefore, Order 7210.3 is the central document that specifically dictates air traffic control operational procedures, making it the correct answer.
