I spent a day at Oshkosh last Monday and had a chance to talk to Trig about their ADS-B plans.

The Trig TT22 Mode S Transponder is currently shipping and supports 1090ES ADS-B Out, if it is connected to an approved WAAS GPS position source. Up to now, approved GPS sources have been quite expensive.

The good news is that around Christmas, Trig is going to start shipping their new, as yet unannounced, TN72 GPS position source. I had a chance to see a prototype. It easily fits in the palm of your hand, weighs about 100 grams, and uses minimal power. While Trig wouldn't commit to a price, the people I talked to said that the unit would sell for less than $600.

Couple this with an ADS-B receiver ($500 - $850), an iPhone, iPad, or Android device, and a low cost app like Foreflight, etc., and you will have a full blown collision avoidance system that will accurately display and warn you about all other ADS-B and/or Transponder equipped aircraft in your vicinity. In addition you will be visible to all TCAS equipped commercial aircraft.

Trig indicated that their distributors have significant discounts available of groups and clubs that organize a volume purchase.

This is a great solution for glider pilots who fly near metropolitan airports and are mainly concerned about collision threats with other GA or commercial aircraft.

Get your checkbooks ready.

You may me correct on this, the TN72 looks like it will require an antenna and a brief search of TSO-C190 antenna much like the one used on the TN70 are upwards of $300.00 and more. Ironically I don't think the TN72 is TSOed but the antenna may well need to be.

The TN72 at it exists today cannot be installed in any certified aircraft including certified gliders. Since it's an experimental market focused product I'm not sure why you are talking about TSO antennas. Having an actual TSO GPS antenna is not a requirement there.

A TN72 can be installed as an ADS-B Out GPS source in an experimental glider, and since it's a "meets performance of TSO-C145c" device it absolutely will trigger TIS-B and ADS-R ground services. But few glider will likely be equipped to receive that data (a PowerFLARM receives 1090ES direct only, it does not receive ADS-R, TIS-B or FIS-B). Trig are good guys they damn well would not sell a product in the experimental market that did not do that correctly (Uh unlike some other folks).

That the TN72 is TSO-C199 certified is irrelevant to any use today since there are no TSO-C199 related use or installation regulations.

What will happen moving forward is intersting. And may change here as TSO-C199 related regulations appear and if (unrelated) ADS-B installation STCs are developed by folks.

For people with a Trig TT-22 in an experimental glider who want to play with ADS-B out the TN72 is good news. It would be great to hear about them being installed and used.

As Andez says all this has been well discussed before, including in posts earlier n this very thread.
