I am interested in what people’s understanding is regarding IFR certification with respect to ADS-B? If your aircraft is equipped with two transponders, a 345R and a 330ES, the first being primary, and you are IFR certified by an Avionics’s shop, would you believe they are required to certify that both units are at least putting out the required ADS-B signal? And, if it were not, then you would not be certified or if primary was but secondary not, that this status would be placarded by the shop and noted in the log entry about the IFR certification?
