Operational use of uAvionix’s situational awareness system commenced at Indianapolis (KIND) and Austin-Bergstrom (KAUS) airports. The system recently passed a service acceptance test in collaboration with Capital Sciences.
The uAvionix FlightLine ADS-B service provides air traffic controllers with "real-time, precise depictions of aircraft and vehicles on the airport surface, thereby improving situational awareness and reducing the risk of runway incursions," according to uAvionix. To ensure visibility of ground vehicles, the airports have installed FAA-approved uAvionix ADS-B VTU-20 Vehicle Movement Area Transmitters on their vehicles.
FlightLine captures ADS-B signals from both aircraft and ground vehicles on the 978- and 1090-MHz ADS-B bands. This information is displayed on an airport surface map showing runways, taxiways, hold ramps, and other movement areas.
