Runway status lights

Some major airport in the United States and abroad use a system called runway status lights. It is a fully automatic, advisory system used to inform pilots and ground crews if the runway is unsafe, i.e. runway crossings or an aircraft is about to takeoff or land. It is designed to prevent the possibility of runway incision incidents.

Link to FAA description of (RWSL):

Another system that some airports are starting to implement is eFAROS, or enhanced final approach runway occupancy signal. eFAROS is a modification to PAPI approach signals that notifies approaching pilots if the runway is occupied. It works fully autonomously, scanning the runway for obstacles i.e. aircraft or vehicles. If an obstacle is detected the PAPI lights will begin flashing to notify an approaching pilot if the runway is occupied.

Runway lighting is one of the major realism wise among such things in a simulator. I hope sooner or later our devolopers will dig much more into details and upgrade the lighting on not only runways but also whole airport environment.

Kind regards.

Just saw a video where there was an issue with the system at SFO. Would be cool to see in FS2020

whatever happened to the fix to turn off runway edge lights during the day?
