Statically it is. Midairs, once the number 1 accident cause, are now

almost

nonexistent in Switzerland, since the introduction of Flarm.



You can also assume that no pilot wants a midair collision and maintains

good look out. But there are limitations to the human senses, as stated

by

Gerhard.



We have to stop threating the glider pilot as a luminous all seeing

perfect

elite being. (paron the pun.) We make mistakes. Hundreds each flight. In

fact its a human quality to err.



Yes it helps, it does not provide the answer as the statement to which I

objected intimated it might. The only solution is better lookout and

bettter situational awareness however THAT can be achieved, not replacing

them with technology.



In answer to the assertion that mid-air collisions in Switzerland have been

eradicated, mid air collisions are very very rare and relying on statistics

with such a small sample is futile. As I recall the only mid air I can

recall in Switzerland over recent year was between two FLARM equipped

gliders, go figure.



Here is where technology helps. It maintains its constant SA and fills in

our human attention gaps.

I hope no one takes Don comments seriously. It is evident he doesn't know what he is talking about with gems like: midairs are very very rare, see and avoid is the only solution to midairs, flarm was designed for wave etc. Please spare us.
