Well what will happen when the new transponders are ordered you have to give your plane’s “N” number and that’s encoded along with the usual altitude and squawk code ... I don’t remember if there’s a certain date you have to have those but the planes I flew in the States some of them had the old ones ....
So the transponders are shipped with that specific craft’s ‘N’ number, after it’s ordered I guess?
Far cry from flight simulators 12 years ago...
How does one sell such used equipment then? Or buy it?
Who encodes the N number & how?
