You're wrong there, Marc. I'm not an ex-fighter pilot, and I had this
warning from my Flarm on the ridge. I took an evasive action and we didn't
collide. 10 sec is a lot when something is yelling at you.

I also suspect that FLARM won't do much to help where I'm most concerned
about a collision with another glider, the ridge running down the White
and Inyo mountains near the CA/NV border. FLARM advertises an effective
range of 2-3 km, or 1 to 1.5 nm. Given a head-on approach between two
gliders, each running at a TAS of 150 knots, you'll be lucky to get 10
seconds of warning. Might work for an ex-fighter pilot, but that's not
much time for someone like me...
