We are happy to announce a never seen before on Flight sim feature, to be included in the upcoming KDFW update:RWSL Lights
Dallas-Fort Worth is one of the first airports in the world that experimented a new kind of runway alert lights, called RWSL. It's made by 3 different lights systems:
REL (Runway Entrance Lights)
THL (Takeoff Hold Lights)
FAROS (Final Approach Runway Occupancy Signal)
REL and THL and strings of red lights that turn on automatically when it's unsafe to enter the runway (REL) or when it's unsafe to takeoff or land (THL). FAROS it's also an alert to indicate there's an airplane on the runway, and it's represented by flashing the PAPI.
The feature is implemented thanks to our exclusive Couatl Python engine, and it's fully interactive with AI traffic and the user airplane. The actual behaviour and location of the light system has been implemented according to the official specifications. You can read more on the RWSL web site: http://www.rwsl.net/
The RWSL system is going to be implemented in the future in 22 other major US airports so, we expect to make this a standard feature for our upcoming sceneries, which is convenient because, the other airport were RWLS was tested, it's KLAX...
This will be available in the next days as KDFW version 2.0, as soon we finish some additional testing, and will be of course a free update for all KDFW customers, in FSX only. There's no FS9 version planned, since it's programmed in Python using our FSX-only scripting engine and it relies heavily on Simconnect.
See below some screenshot of the RELs in action, which are particularly useful in low visibility, so you'll know it's unsafe to cross or enter a runway, even if you don't see the AI which might just be departing.
