I'm looking for information on glider-glider collisions in Switzerland o=
ver the last ten years. I have looked at the website of the BFU:If FLARM s=
tarted its roll out in 2004, then I think that key statistics to compare mi=
ght be:
=20
a) the total number of mid-air collisions in Switzerland in the years 2001-=
2003 inclusive
b) the number of mid-air collisions in Switzerland in the years 2001-2003 i=
nvolving gliders
c )the total number of mid-air collisions in Switzerland in the years 2005-=
2007 inclusive
d) the number of mid-air collisions in Switzerland in the years 2005-2007 i=
nvolving gliders
=20
I appreciate that there may be other confounding factors.
But comparing the above figures would be a good start.
=20
If (d) =3D 2, then (b) will need to be at least 8 to be significantly diffe=
rent.
=20
