ADS-B Non-Compliance in Rule Airspace

[EricJ]

I keep Scottsdale tower (KSDL) on a radio in my office and usually have a browser tab with flightrader24 on it.   There's a lot of traffic that reports and gets handled that doesn't show up on flightradar24, which is ads-b driven for the most part.

One of our local tower controllers at Deer Valley (DVT) told me they have several modes that they can select on their traffic display, only one of them uses the ads-b info, most of the controllers don't use that mode, and even then it doesn't show tail number, etc.   I don't know what it's like on an approach or center or other radar controller's display.   It seems like the practicality is that one might be able to get around unnoticed without ADS-B with a decent likelihood.

That said, every FSDO person I've heard talk on related topics at wings or other events has stressed the difference between inadvertent and willful disregard for regs.   Consequences for inadvertent violations are kept small, while they take willful disregard very seriously.

Be aware, that FlightRadar24 doesn't display UAT ADS-B traffic, only 1090ES traffic.  So those of us flying around with skybeacons and GDL-82s won't show up on FlightRadar24.

Weird.   Myself and my brother have been feeding them data for many years and it never occurred to me that it was 1090-only.   Derp.
