I can't do the PAPR report yet......I don't have a red light on the beacon. ....I know the ADSB is working since I can see it on Flight Aware....
1) curious why you "can't do the PAPR report yet"? You don't need to fly in rule airspace, or for any specific length of time.
A quick 15 minute flight should work, if you're in an area of good adsb coverage.
And I wouldn't worry about raising any FAA red flags by doing a PAPR--
if your ADSB output is not up to snuff, that's already raising it's own red flag.
2) The Tailbeacon has a red "pilot light" on the RH side, it should blink when you first turn it on, read the Tailbeacon paperwork.
FWIW there are about 4 different paperwork items you should read:
there's a flight manual supplement, an installation manual, a user's manual, & a user and installation guide.
I wish they'd just put all that BS into one file, but it is what it is.
FWIW there's also a service bulletin to update the software to version 1.5.1, I believe it has to do with improving the GPS performance.
3) I don't know about Flight Aware, but Flight Radar 24 doesn't track 978 UAT ADS-B devices-- only 1090's.
