Collision Avoidance Systems for gliders

Huh???
If you don't think we should be in the airspace with a transponder, then
why would it matter if it was closed to us? I don't get your logic.

What do you think will happen to us when an airliner hits a glider and it
brings the airliner down?

I just visited ATC last week and looked at what they see of non-transponder
equipped aircraft. It is a little + mark. They ignore them. They can't tell
if it is ground clutter, birds, a mylar balloon etc., so it just plain does
not exist to them.

A transponder equipped glider squawking 1200 will have approaching aircraft
advised of it's presence, even with the glider pilot on 123.3. TCAS in any
fast mover will also alert them of the gliders presence. So with a
transponder, you get 2 chances to be seen. You still have the 182's to
worry about, and that is where the Zaon is a handy device, but it's foolish
to think that you'll be able to maneuver out of the way of a fast mover
with a 20 second alert from the Zaon. It will take you that long to make
the turn and locate them. You'll have just enough time to see your immanent
demise.

having said that, the FAA is acutely aware that there is a growing number
or transponder equipped gliders, many of which can routinely be found
running down the airways and flying near
military and commercial airliners. I continually hear that "we have to fly
though this heavy traffic area, this is just where we need to go to get to
the best soaring" or similar comments....the truth of the matter is, as
long as we have this attitude eventually this will not be an option and this
airspace will be closed to all gliders or all gliders will be required to
have an maintain transponders, communicate with appropriate ATC and get
permission to enter into the shrinking airspace we have come to know and open.
