I still haven't found out what ATC sees. (But I suspect that at least some of them still have those dim screens that you can only see with the lights out in the room.) But what I do know is that I see very little traffic unless I let iFly display airline traffic up in the flight levels. Yesterday I flew for an hour within 15 nm of KRIC, listening to 6 or 8 other aircraft announcing takeoffs and landings on the KFCI frequency but never saw a one of them on my display. And FlightAware didn't track me, either, even though I went up to 2200 feet for a while, hoping to get its attention. That was mid-afternoon, when there aren't many airline ops at RIC, but there's always traffic between 30,000 and 40,000 in this area.

Re: FlightAware "not tracking" you, by default FlightAware filters out position data that it isn't super-confident in, which might apply in the case Don describes above.  To see "everything" FA thinks it knows about a flight, you need a free account on the site.  Once you're logged in, click on your user name in the upper-left corner of the home page and select "My Account".  Next, scroll down to section 6 and select "Show position-only flights".

Subsequent searches on your tail number will likely show more data than searches done with that setting disabled.  While FlightAware has a disclaimer that "data for position-only flights is incomplete and potentially inaccurate", it's been my experience over the last several years that the data is becoming more complete and inaccuracies are rare.  When I do local flights these days without contacting ATC, FlightAware's "position-only data" usually captures my flight from around 800' on up. (I fly in a flat, sea-level, heavily populated area near FlightAware headquarters, though, so maybe I'm in the optimal place for them to watch me.  Your mileage may vary elsewhere.)

Arrrgh. Thanks, Cobra. I've been a registered Basic User for several years--but my iPhone evidently forgot I was logged in. Anyway, I thought I was--and was still logged in with my Mac, which I didn't think to use when looking for my recent flights. The Mac FlightAware showed me; and now that I've logged in on the phone, it does, too.

And it (now) shows part of my track from the most recent flight.

But not much of it. On the 29th I departed KFCI, landed on the river southeast of the bridge (lower right), flew around in that area for a while, and eventually landed back at KFCI. Here's FlightAware's take on it:

Thre green line begins near where I had climbed to 2200 feet. The white lines are guesses.

FlightRadar24 and PlaneFinder never see my Searey, no matter how high I go. That's especially unfortunately because the iPhone version of PlaneFinder has that terrific $5 Augmented Reality upgrade that identifies an aircraft when you point the phone in its direction. (You see an indication of the aircraft apparently flying on your screen, as if you were making a video of it with the phone's camera. If you haven't tried Augmented Reality yet, five bucks is a cheap ticket.)

Today I tried "seeing myself" on FlightRadar24, an ADSB viewing app you can get for free. (Similar to Flight Aware)

Typically, I "see" all the traffic in my area and it is actually quite accurate.  So, I try to "see myself" flyign at 2500 and I get....NOTHING.

I call ATC, and they can see me. I call other traffic - yep, they can see me. However, FlightRadar25 cannot?  I held up the app to my iFly and most other traffic was exaclty like it, but not ME?  I don't understand that, but who knows - so many proclivities with this new system....

I am STILL trying to figure out a way to TELL if my ADSB OUT is working while I am flying....it undermines my confidence when I cannot, as I have to go into DC from time to time and do not want to get stuck there! Or worse, "escorted" out and to some other airport where I get to taste the pavement...

Any ideas on WHY I am not showing on commercial apps showing all other planes?  I am registered and passed the FAA Cert, and everyone else "sees me" on ADSB.

Try FlightAware, Mike. It's the only app I've found that ever sees me. Plane Finder and FlightRadar24 never have. Apparently it's because PF and FR24 only get results from aircraft with 1070 mHz transmitters. Even FlightAware doesn't always work. It has never shown my track for an entire flight, not once.

It's disheartening to find that ADS-B seems to be worse than useless to pilots as a traffic indicator.

But you should know whether the FAA's ADS-B test site tracks you. (I can't think of the proper name right now.) But you have to get high enough to wake it up. It has never reported seeing me unless I got above about 2,000 feet AGL.
