Moshe, there are lots of gliders overflying your airfield with flarm. Perhaps if you had flarm you would be aware of that traffic.

It's a regional thing. I am a US based pilot and I am not aware of any gliders flown at my airfield that have Flarm. (Out of about a dozen.) In our soaring area there is relatively little civilian non-glider air traffic. And within the glider flying community it's a chicken-and-egg thing, it's useless since nobody else has it, so why buy it.

Correction: I think there is ONE pilot here with FLARM. Probably because he goes to contests elsewhere.

You're right, RR. They're coming from elsewhere though - such as your club which is located a lot closer to the Big City. And there aren't enough of them over our heads so far to change the mindset in my club about FLARM. Yes the perception might differ from reality, as we don't know what we would have seen had we had FLARM. The one pilot with (IIRC) FLARM says he sees more GA (non-glider) traffic (via ADS-B) than he would otherwise be aware of. Still it's not a high-traffic area, and nobody here even thinks about transponders.
