One way to fly safe - er, is to avoid being in the vicinity of other
aircraft. Easy for me to say! That might mean no contests?

Given the current turmoil with ADS-B vs. Powerflarm, etc....the smartest
investment might not be any avionics at all, but a ballistic recovery chute.

Mike,
with respect, it seems that you are quite fixated on ADS-B and the way
FLARM was (not) introduced to the US, and that you respond to every
post with that filter. I don't see the turmoil; I have a transponder,
so if you have powerflarm you will see me. If you have ADS-B, flarm,
or powerflarm I will see you, because I am going to have a powerflarm
ASAP. So you have flarm or powerflarm you will see me again. If power
traffic is a threat I will see it (their transponder). If they have
ATC following, or TCAS they will see my transponder.

The turmoil, is it that the exact form of what we will be using in 10
years is not clear? That seems a separate subject. And the ballistic
chute, like that Cirrus had that went through the tow plane, I recall
they burned on the way down, not a fun ride. It's speculation, but if
you project that into next year, and that glider on tow had powerflarm
it (in theory) would have alerted the glider to the incoming cirrus
when it alerted to the transponder and that could have made the
difference.

Any way you slice it the $1,600 seems like cheap insurance to me.

Brian

There are a lot of people drinking the PowerFlarm koolaid. PowerFlarm
will not see everyone. In remote areas, where there are no ADS-B ground
stations and transponders are not interrogated by radar systems,
PowerFlarm will not see other aircraft that are equipped with
conventional transponders or ADS-B UAT transponders.

I'm not pushing any particular technology. My only point is that the
cornerstone of an effective collision avoidance strategy is to have
everyone utilize a single common technology.

Ten years ago that could have been FLARM, ADS-B UAT, or ....... What we
have now is a huge mess, where the FAA is pushing two flavors of ADS-B,
which can't see each other in remote low altitude environments, and now
the glider community is going off on their own with FLARM.

Maybe this will all shake out over the next ten years and everyone will
end up gravitating to one of these technologies. On the other hand, we
could also end up with ten more years of the current mayhem and fatal
accidents.

I am one of the TRIG dealers so take this as you will......but I've
delivered so far about 40 of these...had only one that had an issue that I
know of and it was a user error that cause the failure..and best of all, it
was simply replaced by our distributor, no questions asked for a brand new
one.....so from what I can see these have been absolutely excellent so
far.....and support have been 1st class...I'm still selling and delivering
them now and have not seen any reason not to continue!

There was quite a thread storm 11 months ago here about the TT21
transponder. I assume some of the 'early adopters' here purchased and
installed one. Any complaints??

Are any of them interfaced with a GPS navigation source and being used
for ADS-B out?

Mike Schumann

I really can't say how they are all being used but to be honest, I doubt
it.ADSB isn't high on anyone's list yet
it may be in the future, but I doubt you'll see any real movement to this
direction until and if the FAA demands it....we are all interested in
safety.to an extent...until it starts reaching into our wallets..then we
typically look for toys first...fun to play with stuff.....then ...

I believe I started the thread storm about the TT21. After having a United
737 pass directly below me by about 300'-500' while thermaling, I decided it
was time to install a transponder. Since my plane is certified
Experimental-Amatuer built, I didn't believe I was constrained by the lack
of a TSO for the TT-21, so I ordered one, installed it, and had it certified
for operation.

I have been very happy. I've seen airliners routing around me on several
occasions since install it. With an CA302 & Tasman varios, Microair Radio
recieving, Oudie, and the TT21 replying to queries while sitting on the
ground, my current draw is about 600ma.

John Scott

I have not enabled the ADS-B out, for all of the reasons listed in the
replies, however, having the ability to do it in the future, when it makes a
little more sense, was a significant factor in my selecting the TT21.

Also, I'm using the TT21 with a L2 dipole antenna mounted vertically on the
forward bulkhead of my glider (ahead of my feet. Seems to work really well.
The transmisson pattern has me flying in the center (very small hole) of a
really big donut.

I also have a MRX PCAS in my glider.

I know John knows this, but to be ultra clear to others the Trig TT-21
has since received TSO approval for a Mode S transponder.

BTW like most ADS-B data-out devices currently in use its currently at
the old "-A" standards level and I expect a firmware update to make
them "-B" (i.e. DO-260B) complaint to meet the FAA carriage mandate.
Trig also tells me that firmware updates will an indication that the
GPS source is feeding the ADS-B and the ability to set the transmitter
capability code bits to describe if your aircraft has a UAT or 1090ES
receiver. Currently you can only set the "1090ES" bit. Trig gets
credit for making that setting so easy to do, its not clear other
transponder vendors are/will be.

In addition to the FAA flying Trig transponder for ADS-B survey work I
though that there was at least one Trig transponders flying in a
glider with 1090ES data out today but since the pilot is being quiet
maybe its not. I do know several owners interested in playing. The
hold up on the west coast is lack of ADS-B ground infrastructure and
anybody having an ADS-B receiver to play with. I think once some geeks
get PowerFLARMs in their hands there will be more reason to play
around with the TT-21 and ADS-B data-out.
