Garmin Introduces New GTN Series Software Update

Garmin is pleased to announce the addition of new capabilities and enhancements for the popular GTN 650/750 touchscreen navigators. New GTN features include visual approach guidance, control and display¹ of the GTX 3000 transponder and GTS™ 8000 Traffic Alert and Collision Avoidance System (TCAS II)/Airborne Collision Avoidance System (ACAS II) as well as LNAV+V approaches without Space-based Augmentation System (SBAS) service. These new features bring advanced capabilities and even more functionality to new and existing GTN 650/750 touchscreen avionics.

Visual Approach Guidance

Visual approach guidance is now available within the GTN 650/750, which provides advisory vertical guidance in visual flight conditions based on a published glide-path angle or a 3-degree glideslope from the threshold of the runway, while considering terrain and obstacle clearance. When selecting a visual approach, pilots can choose the runway of intended landing and select vectors for the final approach intercept to assist them in flying a stabilized approach. When a flight plan is loaded, the GTN will also provide a short cut to optionally load and activate a visual approach when the aircraft is within 5 miles of the destination airport if an approach is not already selected. By utilizing visual approach guidance within the GTN, pilots are provided a more stable descent and precise flight path throughout the approach and landing phases of flight while operating in visual conditions.

LNAV+V Approaches Without WAAS/SBAS

Pilots operating into airports throughout the world that are not served by WAAS/SBAS can now receive advisory vertical guidance (LNAV+V) while flying LNAV approaches with the GTN 650/750. By taking advantage of the advisory glideslope offered by the GTN, pilots can more easily fly a stabilized descent while flying LNAV approaches.

ADS-B Capability for TCAS II-equipped Aircraft

GTN navigators can now display1 and control the GTX™ 3000 Mode-S ES Transponder and the GTS™ 8000 TCAS II/ACAS II system from the touchscreen display. Traffic information is overlaid on the moving map as well as the dedicated traffic page. Additionally, aircraft equipped with select third-party TCAS II/ACAS II systems can pair a GTX 3000 with a GTN navigator, which enables control and display capability as well as a simplified and economical path to ADS-B compliance and WAAS/LPV approaches. When paired with the GTS 8000, Garmin-patented TargetTrend™ technology provides pilots with a more intuitive method of judging traffic trajectories and closure rates. The integration of Garmin-patented CLEAR CAS™ (Correlated Location Enhanced ADS-B Receiver Collision Avoidance System) technology uses a blended surveillance method of active interrogation and passive reception of 1090 Extended Squitter (ES) ADS-B data, reducing active interrogations by using intruder position data received via ADS-B-equipped aircraft.

Improved Connext® Interface

Aircraft that are equipped with a GTN 650/750, GTX 345 all-in-one ADS-B transponder and Flight Stream 510 can now receive attitude information through a single Bluetooth® connection via Flight Stream 510.

¹ Display of vertical speed constraints for Resolution Advisory (RA) information requires an approved IVSI indicator compatible with TCAS II to be installed in the Pilot’s primary field of view.
