How do Airplanes Use Radio Stations to Find Their Way?

The ability to navigate using radio signals revolutionized aviation.  It allowed pilots to automatically and continuously find their location in conditions of little or no visibility, such as a cloudy night or a foggy day.  Airplanes were now an effective form of transportation in a much larger set of conditions, not to mention the military advantage of being able to fly in low-visibility situations.Join us on this episode of The Wing Wag as we go discuss how radio navigation works for a variety of different systems: RDF, Reverse RDF, ADF, VOR, DME, ILS, transponders, and LORAN.
