What is the primary purpose of a Letter of Agreement (LOA) in air traffic control?

The primary purpose of a Letter of Agreement (LOA) in air traffic control is to facilitate operational coordination between facilities. An LOA serves as a formal document that outlines the expectations and responsibilities of different air traffic control facilities, such as between adjacent centers or between a center and an airport terminal. It ensures that both parties are on the same page regarding procedures, communication, and the handling of aircraft within their respective airspaces.

This coordination is crucial for maintaining the safety and efficiency of air traffic operations. By clearly defining the operational parameters and protocols within the LOA, it enables controllers to work together more effectively, reducing the risk of misunderstandings and improving the overall flow of air traffic.

The other options, while important aspects of aviation safety and operations, do not reflect the primary intent of an LOA. Safety protocols for inbound flights and emergency procedures are typically covered by other regulatory guidelines or documents. Managing flight cancellations is a separate operational concern that does not fall under the scope of an LOA.
