Would someone provide the link? If it's so, it needs to be publicized better, IMO. |

How it's supposed to work
ADS-B in should bring you weather info and traffic info, called TIS-B or traffic information service. Anybody nearby transmitting ADS-B out info on the UAT frequency will show up directly. Any targets the ATC is seeing on their radar or ADS-B stations are picking up should be re-broadcast to you. But, and this is the rub, if you are not broadcasting ADS-B out, you will not trigger the re-broadcast. You have to count on somebody in the same vicinity as you with out capability to trigger the re-broadcast.
Anonymous mode only works with UAT ABS-B out. If you have a Mode S xpdr, you are never, ever anonymous. Ed Holyoke Quote:

Here's how it is suppose to work:
1. If you have adsb-out, and -in, and are in contact with an adsb ground station, and 2. There is a nearby aircraft that is known to the system-either it has adsb-out and is talking to an adsb ground station, or it is within atc radar coverage, and if it has ASB-out it is on a different frequency than your adsb-in, then 3. The adsb ground station is suppose to send you that aircraft as traffic. Radar coverage is not the same as ADSB ground station coverage. BTW, if you are in VMC collision avoidance with vfr traffic is the pilot's - not ATC's - responsibility. You must keep looking, even if on an ifr flight plan. |
I have 2 planes at Milton...you really have to keep your head on a swivel. You have Navy/Marine Helos and T6's, Air Force T6's and T1's, Hurlburt and Eglin Traffic, plus all the commercial and flight training just within a 20 NM radius. ADSB is always welcome in this area though you won't necc get the whole picture without ADSB out, or someone nearby with ADSB out. They do train heavily at eglin so I'm sure it was as you described, a trainee and a supervisor. However, there are a **** load of aircraft in the local area without transponders as well who don't talk and won't show up on radar or ADSB. It's very surprising that being IFR they were behind giving you advisories. Stay safe out there

If ATC is "painting" his non ADS-B transponer response, then you should see him on your ADS-B display. Don't confuse Primary (raw) radar with Secondary (transponder) radar. The caviat is that you must be within ADS-B ground station coverage to see non ADS-B transponer responses. Quote:
