Following successful tests at Dallas/Fort Worth and San Diego International Airports, acting FAA Administrator Robert Sturgell announced that runway status lights will be installed at 20 more major airports over the next three years. The in-pavement stoplights are automated, surveillance-driven lights that alert pilots of aircraft departing or crossing a runway that it is already occupied and active. The lights are installed at runway/ taxiway intersections and at departure points along the runways.
