The transponder problem is completeley different. In Europe, at least
in France (and probably also in Germany), most gliders are owned by clubs,
as well as loggers and future transponders. In my club, for 20 gliders
we have 5 loggers and this is sufficient, as they are stricltly needed
only for badges and not every pilot fly a badge every day. However
if the regulation about transponders become effective we are going to
be forced to buy 20 transponders.
