Actually the FLARM should light up stable (no blinking, and no sound) for
such a case.
This is a tipical situation with FLARM. It's not a software problem, it's a
radio problem.
The range is drastically reduced by badly positioned antennas, so if you are
not heading towards another unit
there are good chances that sometimes it won't light up, just like in the
video.

If FLARM could transmit at more than those few (20?) mW things would be very
different.
In any case, it works fine when you have frontal traffic because the
antennas are perfectly visible each other.

All users (and in the alps in europe we all use flarms since 2006) know that
their flarm is only an auxiliary help for safety,
and that many times it won't light up for nearby traffic. You must always
assume that another glider is not using a Flarm.
That's imperative.

Is it just me? I am surprised the Flarm doesnt light up more.
Its like the pilot looks right and sees the other glider before the
Flarm lights up.
And that other guy is close!

Actually, that's the whole point of FLARM: It doesn't dumbly warn based on
proximity, but intelligently based on the predicted flight paths. And it
knows about gliders. ;-)
