Los Angeles International Airport (LAX) has a new safety system that alerts pilots to potential runway collisions. Connected to LAX’s ground radar system, the runway status lights alert pilots approaching a runway with red lights imbedded in the pavement if ground surveillance radar detects traffic on or approaching the runway. When pilots see the lights they must stop until air traffic control gives clearance to cross or enter the runway. Ground traffic will also use the system.
The system is currently in use at Dallas/Fort Worth International Airport and San Diego International Airport where it has proven highly effective in preventing runway incidents. The Federal Aviation Administration (FAA) plans to deploy runway status lights at almost 20 other U.S. airports by 2011. More information can be found on the FAA Web site.
