I've looked up the TACAN channels for a number of east coast military airfields on AirNav and have been able to get good signals for several (KNTU, KLFI) but not others (KDOV). it appears that not all TACAN channels are supported in Flight Gear. Is there any way finding out (other than by trial and error) which channels are supported?
Also, in the A-10, I can set the TACAN channel number but have-not found anything that I can click on to change from X to Y. Any suggestions?
