Finishing a build of an RV-7 that has a new Sandia STX-165R Mode C transponder. I would like to meet the 2020 mandate for ADS-B. Sandia website states it will be compliant with a “UAT 978”. I have tried figuring that out, but am running in circles between 1090, Mode S and 978, Mode C. What would I need to purchase in order to meet the 2020 mandate? Thanks in advance.
EFIS is an AFS 5600. Currently the GPS is not the 2020 version.
