Been following this thread, as my glider has a TT21, and not sure what else is connected to it (TN72 GPS?). If I understand correctly, with the TT21 I cannot fly in A, B, and C airspace, but okay to fly in the rest, correct?

Thanks,

Not only can't you fly IN those airspaces, you can't fly OVER them either, which may be the bigger limitation. Going back to Minden from the north the shortest distance may be over the Reno class C airspace, which only goes up to 8,400 ft. But you will need to be in compliance with class C airspace to even over-fly this airspace. The non-compliant aircraft will either have to get a waiver from ATC or fly 20 nm either east or west to avoid it altogether. Never mind that this might put you into conflict with air traffic flying in and out of Reno.
