The January/February 2019 issue of FAA Safety Briefing focuses on Automatic Dependent Surveillance-Broadcast (ADS-B) technology, a foundational component of the FAA’s NextGen system for improving the safety and efficiency of the NAS. Building off our previous ADS-B focused issue in March/April 2017, articles here continue and expand the discussion about the safety and technology benefits of ADS-B, as well as provide important details and updates on the purchase, installation, and operation of ADS-B equipment. For an overview of this issue, check out the article, “Time to Move! — Why ADS-B Matters” atbit.ly/adsb2020. You can download the entire issue at 1.usa.gov/FAA_ASB.
