Garmin Obtains HTAWS Certification
FAA has issued a supplemental type certificate (STC) for the helicopter terrain awareness and warning system (HTAWS) on Garmin’s GNS 430W and 530W. Available as a new or retrofit option, the rotorcraft-specific application features a forward-looking terrain avoidance (FLTA) function and five-color scale to display terrain—red, orange, yellow, green and black. HTAWS incorporates voice callouts when descending below 500 feet AGL, with the ability for multiple callouts at 100-foot intervals below 500 feet. FAA has also approved installation of a vertical helicopter rack for products from Garmin’s GTS8xx traffic series.
