Trig TT21 Transponder ... reports?

Artificial horizons are banned because cloud flying is not permitted
in contests. It's not permitted in controlled airspace the USA at all
unless the glider is IFR equipped and the pilot has a glider
instrument rating; which is possible by the regulations, but I've not
figured out how to do the practical test! The missed approach would
be interesting.

Cloud flying in Class G airspace is technically permitted, but
probably an unwise activity.

BTW ADS-B products used in contests are going to be "interesting" for
the poor CD to deal with, ... not just worry about somebody getting
weather reports. I'd expect Flarm to have that though out given their
existing "stealth mode" and logging of that mode setting.

Couldn't a pilot just have 2 Flarms, 1 to turn stealth mode logs in
with and a separate one to leach with?

You can always try to sneak prohibited equipment into your glider in a
contest - like an artificial horizon, XM radio weather, etc. Be
prepared to get penalized if you get caught.

I do wonder whether contest rules eventually will require pilots to
disable ADS-B receivers that don't have a contest mode - or will just
accept the leeching, "heads-down" and stealth (turning off your ADS-B
transmitter) behavior that would result from broad adoption of
technology that lacks a contest mode.

Another argument in favor of PowerFlarm for competition flying.

You'd have to smuggle it aboard and risk being disqualified and then
if you turned it on both Flarms are going to alert on the other
devices presence. If anybody knows if there is a way to suppress those
warnings and have the smuggled aboard device usable for leaching (e.g.
I wonder on PowerFLARM you might be able to turn the volume down and
even if the built-in display is useless because it has popped up a
traffic alert you might be able to bring up the moving map on an
attached PDA - but you might need to suppress the traffic alert pop-up
on that display (if the software supports that)).

Flarm also logs random position data of other aircraft in the IGC log
file and that can be uploaded to Flarm to do things like help Flarm
analyze effective range etc. and improve their products. I wonder if
turning on another Flarm or PowerFLARM unit in the same glider, even
if you were stupid enough to somehow turn off all the annoying alerts
between each unit and try to use it to leach off somebody that your
"official" FLARM unit would capture the presence of the "illegal" unit
in its IGC log file. Of course to catch you somebody really have to
suspect you are cheating and would then have to analyze your Flarm IGC
log file.

I kind of see it as the workable way in glider contests is you allow/
require Flarm based products and ban other ADS-B receivers (not
transmitters), Mode S TIS, even maybe in-cockpit reception of SPOT
trackers, etc. or you have to open the gates fully and allow any
tracking technology receivers and the full on leaching that probably
implies.

Banning ADS-B in contests???? We are all trying to increase the safety
of aviation by increasing situational awareness for all pilots and you
guys are talking about banning one of the most promising technologies
out there because someone might use it to cheat in a contest?????

Does anyone have any concept on how absurd this makes us look outside
(even inside) of our small insular world???
