Safe Flight 21 and Two Advanced Automatic Dependent Surveillance-Broadcast (ADS-B) Applications

摘要

The joint government and industry Safe Flight 21 (SF-21) Program is incrementally specifying, developing, and evaluating nine operational enhancements in two operational test beds, Bethel, Alaska and the Ohio River Valley. In this paper, two applications under development, Radar-Like Services (RLS) and Cockpit Display of Traffic Information (CDTI) Enhanced Flight Rules (CEFR) are presented. RLS provides radar surveillance services in non-radar airspace while CEFR allows for the use of the CDTI for visual separation. These applications are thought to be two of the more advanced Automatic Dependent Surveillance - Broadcast (ADS-B) development activities, with tangible benefits for their respective user communities.
