U
Ultralight ADS-B?
Guest
Posting here so I can do so anonymously, since I'm probably also going to file an ASRS report on this, although nobody did anything wrong.
I fly an ultralight (in addition to being a professional pilot). Yesterday I was flying at a local uncontrolled field, at about 3000 MSL/1500 AGL (GPS altitude). I have a radio and was making appropriate transmissions on CTAF. I have a form of traffic alerts on a popular ultralight phone app, which uses internet traffic. It showed a jet passing me on the left at fairly close range. When I turned to look and saw, it was extremely close.
I'm not exaggerating that it was close. Overlaying the jet's ground track with mine shows (depending on timing) it could have been as close as 400 feet laterally. Vertically is a little harder to tell, but I was looking mostly level at the airplane, maybe a little bit up.
I checked the various ADS-B tracking sites and listened to liveATC. The aircraft was on approach control frequency, was being vectored for a visual at a local towered field, and was at an appropriate altitude and position for that. Even worse, the controller had given the aircraft two instructions of "turn 10 deg right for vectors", which pointed the aircraft almost right at me. At no point did the pilots report me in sight, nor of course were they warned about me - because I was certainly invisible to ATC.
And that's the issue for me. Nobody did anything wrong. But if I had been in an airplane, I would have had ADS-B, or at least a transponder, and ATC would certainly have not only called out traffic, but would likely have given different headings. The airport I was at, while nobody was flying there at the time, certainly is busy enough that ATC usually would see traffic there and avoid it. But they couldn't see me, because I don't have ADS-B, and as far as I know, can't even get ADS-B on my ultralight in the U.S.
Does anybody know if that's not true? Are there any ADS-B options for ultralights? UAvionix sells one in Europe for drones, but it's something like $3000 (which is about the cost of my ultralight) and isn't available in the U.S. anyway.
I would like the option (but not the mandate) to be able to have a lightweight ADS-B Out transmitter on my ultralight. And I can't be the only one.
This incident was really a pretty close call. I'd like to avoid anything like it again.
