The FAA has completed the deployment of Model X (ASDE-X), airport surface detection equipment used to enhance runway safety, at 35 US airports.
Model X (ASDE-X) will provide a picture of aircraft surface movements to controllers through a variety of sources including radar, sensors from the satellite-based surveillance system Automatic Dependent Surveillance - Broadcast, multilateration sensors and aircraft transponders.
ASDE-X projects this data onto colour displays that allow controllers to see the identity and precise location of aircraft and transponder-equipped vehicles on runways, taxiways and approach corridors, as well as aircraft flying within five miles of the airport, and provides conflict alerts.
