I am in the process of doing an ADS-b out install on my experimental 27b. So far I have a Trig T22 and a T72 GPS installed and operational. I now have a ground/air pressure switch which I will put in next. Two questions for the list;

1) How do I take advantage of the $500 rebate being offered by the FAA?
2) I have heard of some flight test that needs to be performed to confirm functionality of a SIL=3 install. How do I do that?

Anything else I should know?

Thanks in advance for your help.
