A Garmin GTN Xi Unit Installed in a Piston Airplane's Flight Panel

Garmin has introduced a direct slide-in upgrade for its GTN 650 and GTN 750 all-in-one GPS/NAV/COMM multifunction display units. Learn more about the fourth-generation GTN 650 and 750Xi…

Designated GTN 650Xi and GTN 750Xi, the units have received both EASA and FAA approval and are already available to order for fixed-wing single-engine and multi-engine piston, turbine and experimental aircraft. “Helicopter and business aircraft approvals soon to follow,” a company spokesperson promised.

Reflecting on Garmin’s innovation and pioneering in this arena, Carl Wolf, vice president of aviation sales and marketing says “Garmin was the first to introduce the all-in-one navigator with the iconic GNS 430/530.

“Over time the GNS WAAS and the industry-first GTN 650/750 touchscreen navigators were added to the line-up along with state-of-the-art features such as voice control, wireless connectivity and more.”

Faster Rendering, Smoother Panning

Modern processing power and state-of-the-art hardware within the GTN 650Xi/750Xi supports faster map rendering and smoother panning throughout the touchscreen navigator.

The units have large, ultra-high-resolution displays and wide viewing angles, and the displays initialize within seconds of start-up, “providing immediate access to frequencies and flight plan information, saving valuable time in the aircraft,” Wolf adds.

Preserving the same form factor as the previous generation GTN 650/750, the 6-inch-tall GTN 750Xi and the 2.65-inch-tall GTN 650Xi have touchscreen displays with a dedicated direct-to button and dual concentric knob.

Advanced Navigation Functions

When installed alongside a G500 TXi or G600 TXi flight display, the GTN Xi series brings a new level of modernization to the cockpit, Garmin says. The GTN 650Xi/750Xi offer advanced navigation functions, including ILS and LPV instrument approach procedures, as well as visual approach guidance.

Based on a published glide path angle or a three-degree glideslope from the threshold of the runway, visual approaches also take into account terrain and obstacle clearance to assist pilots in flying a stabilized approach to the runway in visual flight conditions.

Approach types that incorporate radius-to-fix (RF) leg types are also supported by the GTN Xi series.

Additional capabilities include the option to add a published or custom holding procedure, vertical navigation (VNAV), graphical flight plan editing on the moving map and more. Geo-referenced instrument approach procedures can be overlaid on the map page, for enhanced situational awareness when transitioning from en route to the approach phase of flight.

Terrain alerting is included within the GTN Xi series and further enhances situational awareness by using its internal terrain and obstacle database to provide audible and visual terrain proximity alerts, including, “terrain ahead, pull up” and “obstacle ahead, pull up.” Helicopter Terrain Awareness and Warning System (HTAWS), TAWS-A and TAWS-B are available as options.

Pilot Workload Reduced

When paired with a GFC 500 or 600 autopilot, pilots can fly fully coupled VNAV profiles and instrument approach procedures. And pilot workload-reducing features such as Telligence voice control is also available within the GTN Xi when paired with the optional GMA 35c.

When paired with a GSR 56 Iridium datalink, global text and voice calling can be completed through the touchscreen display on the navigator. Wireless connectivity is available with the optional Flight Stream 510, allowing pilots to connect their mobile devices running the Garmin Pilot and FltPlan Go applications.

The GTN 650Xi and GTN 750Xi have received both EASA and FAA Supplemental Type Certification (STC) and are available immediately through Garmin authorised dealers with “suggested retail price” of $12,495 and $17,995, respectively. And a free GTN Xi trainer app is available for download on Apple mobile devices, and a new GTN Essentials 2.0 eLearning Course provides instruction for the use of the new GTN Xi series.
