The US Federal Aviation Administration (FAA) has begun trials of an experimental system at Dallas/Fort Worth airport that will help reduce runway incursions.
Trials of the Massachusetts Institute of Technology's (MIT) Final Approach Runway Occupancy Signal (FAROS) system will run for about three months initially. The FAA will be supported by the MIT's Lincoln Laboratory in the trials and could extend the system operation if the trials are successful, said a safety bulletin from the International Federation of Air Line Pilots' Association.
FAROS is designed to help cut down the frequency and severity of runway incursions, the bulletin added. It is operated using aircraft location data from radars.
The system will flash the existing Precision Approach Path Indicator (PAPI) lights to indicate to pilots on final approach if the runway is occupied and unsafe for landing. Trials will be conducted on runways 18R/36L and 18L/36R on the west airfield, 17R/35L and 17C/35C on the east airfield.
