VFRMAP is a new utility that displays your current position over OpenStreetMap. Download and follow the development here.
It’s incredibly easy to use! Just unzip to wherever you want and run the .exe file after MSFS is already running. Then just open a browser window and go to http://localhost:9000, and behold, your aircraft location updated in real time in the map, with additional info above: airspeed, altitude, heading and so on. You can also use the map to teleport to another location anywhere in the world!
What’s particularly great is that this even works if you have a tablet or smartphone connected to the same network. Simply go to the same address and enjoy a second screen where you can always see your exact location in the world.
