Which document defines the jurisdictional boundaries of each sector in air traffic control?

The document that defines the jurisdictional boundaries of each sector in air traffic control is the Letter of Agreement (LOA). LOAs are agreements between different air traffic control facilities or services that specify the responsibilities and procedures for coordinating air traffic between them, including the boundaries of each sector. This documentation ensures smooth and efficient traffic management across different areas, preventing overlaps and potential conflicts.

Standard Operating Procedures (SOP) provide guidance on the procedures to be followed by air traffic controllers but do not specifically delineate sector boundaries. The ATC Manual contains general policies and procedures for air traffic control operations but lacks the detail on jurisdictional boundaries specific to each sector. The Flight Operations Handbook primarily serves as a guide for aircraft operations and does not focus on air traffic control jurisdiction.
