The uk aaib accident report is here
http://www.aaib.gov.uk/publications/formal_reports/5_2010_g_byxr_and_g_ckht.cfm

Safety recommendation 10 asks the CAA to revisit looking into
electronic alerted see and avoid. The previous attempt had ruled out
Flarm without looking in to it at all. They recommended Mode S
transponders for all including paragliders etc, which after full
review was shown not to be feasible. So they did nothing.

If you read the report, you will understand busy airspace. We don't
have anything remotely close to this here.

I have seen elsewhere a view that as Flarm is the only technology that
would work today in uk uncontrolled air space that this is what the
aaib are recommending. Hence my comments to macca.

As to Flarm in general, there is nothing to prevent any ony building a
receiver and getting position and vector data without having a Flarm
chip. So you can have a fully TSO unit without needing to purchase a
proprietary chip from Flarm. You just won't have the glider specific
alarm.

A hybrid system would make most sense. But I'm just not convinced we
need anything. We have no busy airspace at all except at a gliding
comp
