What exactly is radio navigation? In short, radio navigation is the art of locating your position on the earth by use of radio waves. Radio waves can be used to find direction (bearing), distance (ranging) and also velocity to or from a station.
I was recently ask why Coolsky doesn't develop for and support Lockheed Martin's Prepar3D flight simulator. The discussion quickly turned into one about the future of flight simming since P3D is often held up as the future of flight simming. I will try to explain here why I don't develop for or support P3D, and why I don't think it is the future of flight simming.
