In our busy Chicago airspace, the new 1202 code works beautifully.
Twice now I came back from a x-country skirting the Aurora D-airspace
and listened to the tower frequency. They must have a radar feed from
Chicago approach because tower pointed out my location and altitude to
ac flying in and out of Aurora. They identified me as a glider
because of the special code. Of course I talked to them to let them
know I'm on frequency and that I had traffic in sight. Chicago Glider
Club itself is right under the Western approach into Midway via the
Joliet VOR and we often have traffic right at 4-6,000' over the
field. Transponders and the new code are really effective in helping
ATC keeping us separated. All club gliders and 80% of private gliders
are Mode-C equipped.
