Honeywell and Sensis demonstrated in August a concept of providing automated, individual voice warnings to pilots about to fall prey to a runway incursion accident. Unlike the current procedure, the concept technology issues the warning to the pilots at the same time as the air traffic controllers. At present, the controller becomes aware of a potential accident, identifies the aircraft involved and then warns the pilots, a process that consumes precious time.
The concept combines Sensis airport surface detection equipment, type X (ASDE-X) and its associated Safety Logic system with Honeywell’s aircraft mode-S transponder and TCAS units. Essentially, while the radar tracks all surface traffic, the Safety Logic component uses the fused data of the ASDE-X system (surface movement radar, multilateration, ADS-B) to precisely position all aircraft and vehicles and then continuously assess the multiple possibilities of incursion threats.
