Garmin has released expanded features and new enhancements for the GTN touchscreen avionics.
New capabilities include customer-requested features, such as creating and executing customized holding patterns, search and rescue patterns, as well as animated NEXRAD weather imagery from a variety of weather sources.
The GTN 650/750 incorporate enhanced navigation functions that are commonly found within Garmin Integrated Flight Decks, including the display of fuel range rings, the ability to fly Instrument Approach Procedures (IAPs) with radius-to-fix (RF) leg types, and the option to load a secondary approach while flying a missed approach segment. Many of these new features are enabled by a free software update, according to company officials.
Pilots who fly with the GTN touchscreen series now have the flexibility to build customized holding patterns. These holds may be created over an existing fix in the navigation database or over a user-defined waypoint and inserted into a flight plan or via direct-to navigation. When creating a hold, pilots can input inbound or outbound course guidance, select left or right turns and specify leg length in time or distance.
Additionally, pilots may input an Expect Further Clearance (EFC) time, which populates a message on the display of the GTN as a reminder to depart the hold or contact ATC. Unpublished holds or those assigned by air traffic control are easily created and displayed on the GTN 650/750 to simplify the process of flying a holding pattern. With a compatible autopilot, this process is further simplified to support flying the entry of the hold and the holding pattern, Garmin officials noted.
Radius-to-fix (RF) leg support within a retrofit navigator provides customers with additional instrument approach options. With the GTN touchscreen series and a digital Horizontal Situation Indicator (HSI), including the G500 or G600 flight displays, pilots can now fly RF leg types, which are sometimes found in complex Instrument Approach Procedures. This new capability provides pilots with greater access to airports in areas of the world where instrument approaches are nestled among terrain-challenged environments, company officials said.
Additional instrument approach enhancements include the option to load a secondary approach during the missed approach segment, so pilots can have time to prepare for the next approach sequence. For added situational awareness, waypoints prior to the final approach fix (FAF) are also displayed when selecting a vectors-to-final (VTF) transition.
Based on a number of customer requests, additional features provide pilots with a variety of enhancements to their existing GTN 650/750 series products, including:
- GTN COMM/NAV control from G3X Touch display
- Additional Metric and Imperial unit display options
- Updated ownship fixed-wing aircraft icons
- LP+V approach support
These new features are expected to be available in the third quarter of 2015 from Garmin Authorized Dealers for hundreds of aircraft makes and models.
