That still won't make any aircraft equipped with this visible to a PowerFLARM.


No, but since you still have to have a Mode A/C/S transponder when you install the ADS600_EXP, that aircraft is ALREADY visible to a PowerFLARM.

You CANNOT have JUST an UAT-based ADS-B in/out system. It's either UAT-out/in WITH a Mode A/C/S transponder, OR 1090 ES ADS-B out, and UAT-in for the freebie weather and traffic, etc.

RTFM, guys!

You are totally mistaken that everyone who installs ADS-B OUT needs to have a Mode C or Mode S transponder. For starters, gliders are totally exempt from both the ADS-B OUT and transponder mandates. That also applies to all other aircraft that either do not have electrical systems, or operate outside of the Mode C veil and below 10,000 ft.

With the cost of ADS-B OUT UAT transceivers dropping below $1,000 it is totally conceivable that a significant number of glider pilots will buy these systems and not invest an extra $2K in a transponder. Some pilots may elect to invest in portable UAT transceivers that they can share in a club environment.

This will not make the glider visible to today's airliner TCAS systems, but it will make the glider visible on ATC radar. Hopefully ATC will have the common sense to vector any traffic around you. In addition, the UAT transceiver equipped glider will clearly see the big iron traffic and be able to stay out of the way.
