Living With ADS-B

摘要

Automatic Dependent Systems-Broadcast, or ADS-B, sounds like some new alphabet-soup group but it's not. The program was originally conceived to provide aircraft operating in areas of poor radar coverage the ability to self-separate in IFR conditions. Known as Capstone, it equipped aircraft operating around Anchorage, Alaska, in the 1990s with ADS-B tranceivers (the Garmin GDL 90) and either Chelton or MX200 PFD/MFDs.
