SSR Mode S Reasons RNAV

SSRSSR —Secondary Surveillance Radar Mode S uses datalinking to provide a whole wealth of information to ATCATC —Air Traffic Control beyond position and altitude of aircraft. The consequence is that ATCATC —Air Traffic Control have vastly higher situational awareness. While communications can be reduced as a consequence, they are not eliminated entirely, and it is still incumbent upon controllers and pilots to maintain separation.
