Thanks for posting. I had missed the part about the test being in ADSB required airspace. In practical terms, for most of us, that means over 10,000'.
 
ADS-B

This is exactly what happened to me. I was sure I had to fly in the coverage
area because the email I got from the FAA says to refer to the adsb coverage area and they give you a link to their map. So that's what I did and got a fail report.

I get it now, fly in the airspace that will require ADS-B out in 2020. How easy it would have been if that sentence was used.

It's funny because the report said my equipment was working fine but I still did not pass because I didn't fly in the right airspace for 30 mins.

At least I know my stuff is working right now i just have to go fly again.
