After you click on the "ADS-B" button as Cobra mentioned, it will show the location of the active "Radio Stations", or ground transmitters. But there are three more buttons in the upper right quadrant: "En Route" will actually show you the coverage service volume you can expect when flying at altitude; "Terminal" will show you the airports which have ADS-B coverage in the terminal area; and "Surface" is, well, "Fahgettaboutit!" The note at the bottom in the Gulf of Mexico will tell you the information is current as of date. ===Ralph
