The US 15M/Standard Class Nationals required FLARM to be in stealth mode for the duration of the contest. I have to say, I absolutely enjoyed the experience. FLARM became what it was always supposed to be - a collision avoidance tool - rather than a tactical leaching tool. I found that I would get alerts for gliders in the same thermal or approaching/exiting the thermal up to about 1 mile away, but no more. Not a single surprise conflict from a FLARM-equipped glider.

I wonder if others had the same positive experience. I would hope other contests would consider requiring Stealth Mode.
