While ADS-B traffic is comprehensive, there are limitations to the service including line of sight to station, nonequipped areas, GPS signal integrity and non-participating aircraft. The Lynx NGT-9000 has the option to be equipped with the L-3 NextGen Active Traffic® system. This enablement blends ADS-B with active traffic data, providing an uninterrupted display of aircraft equipped with Mode A, C and S transponders. Adding NextGen Active Traffic also enables extended aural alerting of intruder aircraft position such as “Traffic, 1 O’clock High, 2 Miles.” Existing SkyWatch® owners can opt to re-use the system’s antenna and cables. The L-3 NextGen Active Traffic enablement is built into the NGT-9000+, eliminating the need for an external box, saving weight and installation costs.
