If you fly with other gliders, especially cross-country FLARM is the way to go.

I have had several alerts at high altitude and high speeds that I would have never seen the other gliders in time without FLARM.

I flew US Nats in 2009, 2010, and 2011. Three mid-airs, one fatal. Since 2012 all nats have had mostly FLARM equipped gliders, no mid-airs. I would not race without FLARM now and all our local group uses FLARM.
