I recently took possession of a plane that had not been used for 5 years. Had a uAvionox tailBeacon installed to comply with the ADS-B mandate. Performed a flight this afternoon according to the requirements on the uAvionix web site regarding the operational flight evaluation. Submitted a performance request on the FAA web site, but the request failed to generate a result. I got flight following for both directions of the flight, flying over the KSMF class C air space. Would ATC have let me fly over the charlie if the ADS-B was not working?
