Competition mode might be considered to slightly reduce safety but
stealth mode (which is the mode mandated at UK contests this year)
should not diminish the collision warning functionality. I think that
the naming of the two modes could be improved. There is a good
explanation of them he

http://www.flarm.com/support/Flarm_Competitions.pdf

BTW - the early LX Red Box Flarm remote displays had only red LEDs but
all 2006 onwards Swiss Flarm and later LX displays have the two
colours. I presume that the glider in the video had an early Red Box
and I think that all the Flarm display lights in the video are
proximity alerts rather than collision warnings - which is why the
direction sometimes switches as a different glider in the group
becomes he closest one.

It is good to see a positive attitude to Flarm use emerging in the
US. For those who feel that there is no point in having one unless
every glider does "it ain't necessarily so". The gliders that we are
most likely to collide with are the ones that we would least like to
take out our: friends who we fly XC with, other competitors in a
contest and training gliders doing multiple circuits at the home
field. Concentrating on organizing clusters of Flarms in the gliders
that are relevant to one's own circumstances can improve personal
risks (of death or regret) quite considerably more than is apparent
from the overall proportion of gliders with the device. Peer pressure
works quite well to encourage such clusters and helps them to spread
out.

Hi,

To me the stealth and competition modes are a bad idea. *They reduce the
effectiveness of the alerts.

As a sometimes contest manager, I would never mandate anything that would
reduce safety.

Green is proximity red alarm.Stealth is compulsory in rated comps to
reduce
leeching.There has been a lot of discusion in the uk about degrading the
signal for comps,but there seems little choice because you can see
everyone elses speed and rate of climb on the pda if they are not in
stealth mode.

Green??
I dont think so, the only green leds on flarms are those blinking for gps

transmission, power etc.
All informations are red, either fixed or blinking.
I dont think they were in "stealth" mode, it is tricky to use it and -

then - your PDA won't receive traffic informations.
Moreover, stealth mode is bypassable using an alternative "compatible"

device, on the market, so it is not a choice.

It looks like the pilot has put his FLARM in stealth mode. In this mode

only situations in which an impact is expected within the next 18
seconds
are annunciated as proximity warnings (alerts). The stealth mode is
used

by some pilots to make their position data and lift and sink
information

unavailable to other pilots, if this information is not necessary for
proximity warning.

The display used in this gilder annunciates proximity warnings
(alerts)
in
red, mere proximity information would be displayed in green.

the guy shooting the video has a Flarm on top of his panel, in some
of
the scenes you can see the display lighting up and see the target
sailplanes. I thought this was pretty cool to see Flarm in action.

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!
