The aircraft density in the airspace is growing, and this may increase the risk of accidents. In this sense, it is very important for air traffic controllers to work under safe traffic conditions, which include a good airspace division. The goal of this paper is to study the use of a well known airspace complexity measure, applied to evaluate air traffic controller workload in different organizations of the airspace around Sao Paulo. The results obtained by simulating two different scenarios show the relations between sector geometry, complexity and controller workload conditions. The case study here presented allows deducing that the division of sectors with high complexity function helps to lower the systemic complexity. This division was attempted, together with task reassignment, by eliminating the planning controllers, and the number of controllers was reduced from 18 to 12. However, some safety indicators, as the controller task load and the occurrence of conflicts, have shown that the planning controllers have an important role in conflict detection and resolution and, consequently, in the safety of the system.
