The GTN series combines touchscreen data entry and integrated radio tuning with vivid display features. These features include detailed mapping, the option to display and control TAS/TCAS traffic, datalink weather, weather radar, and more. The GTN also supports remote transponder and audio processor control, saving valuable panel space. Garmin’s GTX 32/33/33D remote transponders (sold separately) interface with the GTN so that pilots can control transponder functions from the GTN display. Optional Extended Squitter (ES) versions of the GTX 33/33D Mode S transponders are also available, which support ADS-B Out. Garmin’s GMA 35 remote mount audio processor (sold separately) interfaces with the GTN 750 series and makes it possible for the GTN to control the helicopter’s audio and intercom functions. The GMA 35 also offers an optional control panel configuration to accommodate the right-seated pilot and allows for workload-reducing technologies in the cockpit like Telligence™, a speech recognition feature that lets the pilot activate certain audio panel functions using voice commands.
The GTN series for helicopters incorporates three helicopter-specific databases, including an obstacle database that adds nearly 30,000 additional low-altitude obstacles. A new terrain database has been enhanced to display up to 2.5 arc second terrain resolution, among the highest resolution terrain available in the industry. This high-resolution data improves terrain alerting by reducing nuisance alerts when operating at low levels. Finally, the helicopter navigation database lets operators navigate to over 7,000 additional heliports without having to create user waypoints at these locations.
Built-in HTAWS is optionally available to provide operators with visual and audible alerts of potential terrain and obstacle conflicts along the flight path. Garmin HTAWS incorporates a high-resolution, five-color terrain scale (red, orange, yellow, green and black) and also gives voice callouts in 100 foot intervals when descending below 500 feet. Voice callouts operate in all HTAWS modes, and Garmin’s technology allows the pilot to select multiple callouts descending from 500 to 100 feet Above Ground Level (AGL). An optional radar altimeter input brings even greater accuracy to those alerts. In addition, Garmin’s HTAWS offers a Reduced Protection (RP) mode that allows low-level operations with minimal alerting while continuing to provide terrain and obstacle protection.
Because many helicopter missions require the use of night vision goggles, the GTN series is optionally available with NVG compatibility straight from the factory, reducing the need for aftermarket NVG modifications.
To further help reduce pilot workload, the GTN supports the installation of remote switches on the cyclic or the collective allowing the pilot to create fly-over Mark on Target waypoints or remotely tune frequencies, all without letting go of the controls. The GTNs can also integrate with Garmin’s G500H™ flight display system for optimal situational awareness.
An additional update adds enhanced lighting control that provides even more flexibility for the display’s brightness. An optionally installed pilot selectable switch can be added for easy toggling between brightness configurations for day and night operations. Other updates include support for metric fuel units and map display enhancements.
