Garmin has received FAA STC approval for its helicopter terrain awareness and warning system for the GNS 430W/530W GPS/navcoms. The HTaws is available immediately as an option on newly purchased systems or as a field upgrade for current owners. Garmin’s HTaws has forward-looking terrain avoidance capability with visual and aural advisories to keep pilots informed of hazardous terrain and obstacles. It incorporates a five-color terrain scale (red, orange, yellow, green
and black), and gives voice callouts when the aircraft is descending below 500 feet. Voice callouts operate in all HTaws modes, and Garmin’s technology allows the pilot to select multiple callouts, in 100-foot intervals, descending from 500 to 100 feet agl. Meanwhile, in partnership with Rotorcraft Services Group, Garmin also obtained STC approval for installation of the Garmin G500H glass cockpit in the Eurocopter AS350B2, AS350B3 and EC130B4 helicopters.
