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 after the January 2020 equipage mandate.
- A key emphasis of the AC is that ADS-B is not a replacement for visually scanning for traffic and can be a distraction.
- The advisory circular details specific ADS-B equipment requirements, such as 1090ES for Class A airspace, with 1090ES or UAT (978 MHz) being acceptable outside of Class A.
- It also covers procedures for utilizing ADS-B In, special missions, exceptions for aircraft without electrical systems, and the necessary flight plan codes.
