1) Yes, and practically I don't know of any manned aircraft ADS-B out transponders that are using 978mhz. If there are any (perhaps for helicopter only?) they are rare. You can output on either frequency below 18,000, and must use 1090 above. 2) There are two testing grounds that I know of...

I think there's less of a barrier to this with cars than aircraft, to be honest. An acquaintance who did some contract IT work for the FAA aptly described the organization as "a computing museum," lol.

When on an approach in instrument conditions, the entire area occupied by the approach procedure is cleared of traffic. ATC only lets them in one at a time... If there are multiple airplanes arriving at the same time that must use the same approach and they can't stagger them in by speed, one...

Outside of a few rare approaches, an airplane is only going to be below 500 feet within 2 miles of the end of a runway.

Bumping this a bit since I'm doing drone research, but am a fixed wing airplane pilot and have installed and owned multiple ADS-B transponders in manned aircraft. CAVEATS ADS-B uses two frequencies, 978mhz below 18,000 and 1090 mhz above. The only way to get a 'complete' traffic picture is...
