Dave,
ADS-B... That's it. Thanks.
Well if all planes have "mode C" transponders in them, couldn't I put the Airnav Radarbox on the spare seat of my plane and take it with me?
I would get a real time 3D picture of what is going on around me.
But saying that, what I have seen, the program is pretty harsh on the machine, and most lappys won't handle it too good.
:)
