25 octobre 2017 - The Federal Aviation Administration (FAA) issued a Safety Alert for Operators (SAFO) 17011 on September 28, 2017, to ensure that aircraft operators, pilots and airport personnel are aware of the installation, meaning and use of Runway Status Lights (RWSLs). RWSLs are fully automated systems of red lights that are designed to aid in preventing runway incursions and ground collisions. The RWSL system integrates airport lighting equipment with approach and surface surveillance radar systems to provide aircraft and vehicle crews a visual cue indicating when it is unsafe to enter/cross or begin/continue takeoff on the runway.
