With all this discussion going on now, maybe someone with some
knowledge or experience could enlighten us on the consequences of 10 or
more sailplanes in a tight gaglge all squawking the same info. Will
ATC see them all? Or will interference and/or filtering software at
ATC make some or all of them invisible?

Will TCAS be able to make sense of all these close together
transponders?

Remember, the typical application of the transponder is to separate
traffic, so it is very unusual to have two (in our case 5, 10 or even
40) or more within 1,000' of each other. Can furrent technology deal
with that, or will equipping all sailplanes create more problems than
it solves?

Thanks
