works to see the airliners descending into the local class B.
It's a carry over from his powered aircraft. And if he's close enough
for
the airliner to be an issue, he's within the hockey puck airspace to
piggyback on the TIS-B data being broadcast to the airliner. So the
airliner sees the glider 1202 code.

Bill, unfortunately, no airliner can see any code of a transponder.
Airliner TCAS only shows two different symbols. A solid white diamond
or a hollow white diamond identification on its TCAS when there is no
threat. The solid white diamond display identifies that it has an altitude

encoder with its transponder, the hollow white diamond just says there
is a transponder out there with no altitude encoder or the encoder
function is not operating. The solid white diamond will give altitude
above or below the airliner. The Airliner TCAS will react to a solid white

diamond(ie a transponder with altitude encoder) The white diamond
will change to blue if it is being interrogated on a transponder code
other then VFR. The diamond will change to yellow or red if the TCAS
believes it will be in the projected path of the airliner. It will not show

that it is a 1202 glider! Doug
