Garmin’s new GTS 825 TAS (traffic advisory system) and GTS 855 Tcas I (traffic alert and collision avoidance system) had already received FAA technical standard order approval when they were introduced in March. Garmin is now working on approved model list supplemental type certificates for the GTS 825 and 855.
Both systems offer improved performance and range, according to Garmin, and include Garmin Clear CAS technology, which stands for correlated location enhanced ADS-B receiver collision avoidance system. Clear CAS correlates active (from the GTS systems) and passive (from ADS-B) surveillance data to give pilots a clearer picture of actual traffic hazards. Garmin expects to add the capability for GTS systems with Clear CAS “to provide enhanced information about a target aircraft, including flight ID, altitude, velocity and direction on select displays.”
