Sorting Out ADS-B
If you don’t know much more about ADS-B than that you gotta have it by the end of this year, you’re not alone. Here’s an ADS-B overview to help you get going.

Well, it’s not entirely “dumb” in that you can enter a four-digit base-eight (no 8s or 9s) code on the instrument and when the transponder responds to an interrogation, it puts that code and even your present altitude (to the nearest 100 feet) onto its outgoing signal. ADS-B Out keeps that but takes it a bit further.
