What does LOA stand for in air traffic coordination?

In the context of air traffic coordination, LOA stands for Letter of Authorization. This document serves as an official agreement that outlines the procedures, responsibilities, and limitations associated with the operation of specific air traffic services or airspace segments. The Letter of Authorization ensures that all parties involved are aware of the rules and protocols that govern the coordination of flights, especially in complex airspace environments or when multiple agencies are involved.

The terminology of a Letter of Authorization is widely recognized within the aviation industry, particularly in collaborations between different air traffic control entities, such as regional air traffic control facilities and military operations. This ensures clarity and safety in the management of air traffic and is critical for maintaining orderly and efficient airspace usage.
