I had contact with the manufacturer about using it at flight schools.
I guess in theory all mode S transponders should be trackable in some way, even without some additional info although the Dutch system does not display them.
The manufacturer is happy to provide a license for (almost) free to the first flying club who wishes to implement the system. In all he expects the total installation cost including receiver, old pc, the license to cost no more than about 700 euros.
If a club could make it to work they could track their own planes, parachute clubs could keep an eye on their drop zone etc.
To me it sounds like the future of flying clubs (RAC, interested?)
Interested clubs can PM me and I ll put them in touch with the guy i ve been emailing with
