The FAA’s newest runway safety enhancement tool, runway status lights (RWSLs), became operational on July 25 at Washington Dulles International Airport (KIAD). The new system uses a series of colored lights embedded in the runway and taxiway pavement to help prevent runway incursions by offering pilots and vehicle operators a simple visual system to determine whether it is safe to cross or enter a runway.
