A computer system that receives radar track data from all 20 Continental U.S. air route traffic control centers, organizes this data into a mosaic display, and presents it on a computer screen.

The ASD provides the traffic management coordinator with multiple methods of selection and highlighting of individual aircraft or groups of aircraft. The user has the option of superimposing these aircraft positions over any number of background displays, which include ARTCC boundaries, any stratum of en route sector boundaries, fixes, airways, military and other special-use airspace, airports, and geopolitical boundaries.

By using the ASD, a coordinator can monitor any number of traffic situations or the entire systemwide traffic flow.
