What does "sectorization" refer to in air traffic control?

In air traffic control, sectorization refers to the distribution of air traffic management responsibilities across different sectors or areas of airspace. This organizational strategy allows air traffic controllers to manage specific portions of airspace efficiently, ensuring that air traffic is balanced and that controllers can maintain a high level of situational awareness and safety. Each sector is assigned to a specific controller or team, which streamlines communication and facilitates more effective handling of aircraft movements within that designated airspace.

The importance of sectorization lies in its ability to enhance operational efficiency and safety. By dividing the airspace into manageable sectors, air traffic controllers can focus on a limited number of aircraft, reducing workload and allowing for more precise coordination and communication. Additionally, this approach can help in optimizing the flow of air traffic, minimizing delays, and improving overall air traffic management performance.
