I can only go on what the Europeans have said .... but it looks
like they get a warning on the Flarm and actually find another
Glider where the Flarm indicates it would be. That's a pretty good
test I reckon.
What happens when they don't get a warning on the FLARM even though
there
is another FLARM-equipped glider very close by which they haven't seen?
(which is what Don Ingram was getting at wrt the reliability of the
communications channel)
You can beacon your position and height as often as you want and it
won't make a lick of difference to your survival rate if the
communications
channel you're transmitting on is compromised, and nobody else can hear
you.
You said the Europeans say they get a reliable indication. I put it
to you that it's absolutely impossible to determine whether the
indication is reliable without being able to quantify the false
negatives.
And false negatives are precisely the class of FLARM failure which will
totally fail to be revealed in anecdotal evidence.
