Does anyone know of a source of any statistics that

in reducing the rate collisions between FLARM fitted

in widespread use?

Thanks in advance.

Not really statistical proof but all I have. Number of collisions in
Switzerland:

2002 and befo average about 2-3 gld/gld collisions per year, worst
year was about 5!
This is from memory.

The following is from here
http://www.segelflug.ch/d/6safety/pd...elle_97-06.pdf
2003: 2 (1 gld/gld and 1 cable)
2004: 3 (2 gld/gld and 1 cable)
2005: 1 gld/gld
2006: 0 AFAIK

Switzerland has a FLARM equipment rate of about 90%
