US Airways selected Saab Sensis Corp.'s Aerobahn airport surface management system for use at its three hubs located at the Charlotte-Douglas, Philadelphia, and Phoenix Sky Harbor International Airports. Aerobahn combines airside operational information, such as flight schedules, planned arrival and departure gates, and passenger/bag connection information, with precise aircraft and vehicle surveillance and identification for a real-time, comprehensive view of surface operations. In addition to situational awareness, Aerobahn offers users a number of customizable tools to assist in the proactive management of surface operations, including departure/arrival queues, runway use status, and traffic flow monitoring to minimize emissions while maximizing on-time operational performance. Saab Sensis will integrate US Airways' workflow processes into Aerobahn for a centralized, automatically updated system that tracks the steps needed to manage arrivals and departures. In addition, by using proprietary US Airways data feeds, Aerobahn will display the aircraft position and state in the gate areas without deploying a gate surveillance system.
