Philadelphia International Airport (PHL) has introduced Sensis airport surface detection equipment as part of the FAA's ASDE-X programme.
Model X (ASDE-X) is a runway incursion detection and alerting system that combines surface movement radar, multilateration and automatic dependent surveillance – broadcast (ADS-B).
The system provides air traffic controllers with real-time position and identification information of aircraft and vehicles on the airport surface.
It is designed to use multiple surveillance technologies to provide a comprehensive picture of ground operations, increasing controller situational awareness and improving airport safety in all weather conditions.
ASDE-X also features Safety Logic, a runway conflict detection and alerting technology.
Safety Logic is designed to use complex algorithms to alert controllers of potential aircraft or vehicle incursions.
ASDE-X also serves as the surveillance source for the FAA's Runway Status Lights programme.
The Runway Status Lights programme addresses the National Transportation Safety Board's (NTSB) recommendation for potential incursion warnings to be delivered directly to the cockpit.
