Workload evaluation of sectorized air traffic control and stream management

Stream management is a novel air traffic control operational concept in which controllers control streams of aircraft that are functionally equivalent, rather than being responsible for “aircraft in airspace.” One of the potential benefits of stream management is workload reduction for the same amount of aircraft handled. An adaptation of the dynamic density workload measure was used to evaluate stream management operations against current sector based control. This evaluation is completed using FACET software and ASDI data. Stream visualizations and data analysis demonstrate the advantages of stream operations.
