As we turned over the calendar on 2020, the era of required ADS-B equipage in the United States began—with certain exceptions. To this end, the FAA released its advisory circular, AC 90-114B, “Automatic Dependent Surveillance-Broadcast Operations,” on December 30, to provide guidance for those pilots flying under Part 91.
FAA Releases Advisory Circular Covering ADS-B Ops
Key Takeaways:
- The FAA's AC 90-114B provides guidance for Part 91 pilots on Automatic Dependent Surveillance-Broadcast (ADS-B) operations, clarifying FARs 91.225 and 91.227 as the equipage mandate began in 2020.
- The advisory circular details specific ADS-B equipment requirements, mandating 1090ES for Class A airspace and allowing either 1090ES or UAT for operations outside Class A.
- A key caution in the AC's "Limitations" section stresses that ADS-B is not a replacement for visually scanning for other traffic and could potentially be a distraction.
