This image is an example of AS&T's ability to control the airspace


Data Sources

A comprehensive list of data sources is used assess all factors influencing NAS operations including, New NAS Entrants, Weather Data, VFR and IFR Air Traffic Data, Surface Data and ADS-B.

Airspace Analysis

Software suite that models and simulates airspace constraint scenarios and analyzes the impacts on the NAS. The analysis can include both primary and secondary effects of the airspace constraint.

Visualization Capabilities

Airspace Visual Display (AVID™) is a "fast-time/real-time" situation display process that shows flight progress, user-controlled geographic information, airspace structures, and other user-controlled geographic information.

Intelligent Conflict Resolution

The software uses algorithms to develop mitigation strategies that minimize the impact to the NAS resulting from airspace constraints. Mitigation options can consist of aircraft reroutes, time-based flow management, or other user defined airspace specifications. 

AwTrak™

AwTrak Trajectory Generator is used primarily to create 4d trajectories for all aircraft operating in US domestic and Oceanic airspace. It also will produce several flavors of trajectories.

AwSim™

The main output produced by AwSim is a stream of trajectories (i.e. objects encapsulating a 4-dimensional profile of a moving vehicle in an Earth center coordinate system). The segments from which trajectories are built can be made to snap to an airspace structure (i.e. aerodomes, fixes and airways) or alternatively, they can be generated in a free-flight unrestricted fashion. The user can set the parameters that control the statistical distribution functions from which the population of segments is drawn. The variables under control (all of which have their separate distribution function) are: segment speed, segment length, Gaussian transverse deviation, segment altitude, start and end location of the trajectory, number of segments in a trajectory and start time.

Avid™

Airspace Visual Display (Avid™) uses adaptation data and trajectory objects (from any source - simulator, recorded live data, etc.) to allow for visualization of air traffic at any time instant. Avid™ shows selected layers of adaptation data (airspaces, airports, waypoints, etc.), the two-dimensional trajectory representation and position of the aircraft (the Target objects) at a selected time instant. The "sim time" is selectable from the user interface, and settable to any sim-to-real time ratio, so that the display will emulate a real-time one.
