garmin announces availability of txi, gtn and gfc software upgrades

August 31, 2018

Garmin has announced the availability of multiple software upgrades and approvals across several products including the GTN 650/750 touchscreen navigators, the G500 TXi/G600 TXi and G500/G600 flight displays, as well as the GFC 600 & GFC 500 autopilots. These Additionally, the G5 electronic flight instrument for certificated aircraft is approved for use as a standby instrument when paired with the G500 TXi or G500 flight displays. The GFC 500 autopilot is also approved for installation with the G500 TXi or G500 flight displays, while the addition of descent vertical navigation (VNAV) within the GTN aids in descent planning. With Garmin, pilots receive a seamlessly integrated cockpit that offers a more harmonious transition among avionics, which reduces pilot workload and provides a superior in-flight experience.

GTN 650/750 descent vertical navigation
To assist in descent planning and energy management, pilots can take advantage of VNAV profiles throughout the enroute and terminal phases of flight within the GTN 650/750 touchscreen navigators when they’re paired with the G500 TXi/G600 TXi, G500/G600 or G5. Within the GTN, pilots can easily enter altitude constraints on the flight plan page to set-up a vertical descent profile. Pilots also experience a near-seamless transition from VNAV to an arrival and instrument approach. Once an arrival or approach is loaded and activated, the GTN automatically populates step-down altitudes or any applicable altitude restrictions. If ATC issues an unpublished altitude restriction, pilots can enter those altitudes manually into the active flight plan under the VNAV field.

Approved as a standby: G5 electronic flight instrument
The ever-popular G5 electronic flight instrument is now approved as a standby flight instrument when paired with the G500 TXi or G500 flight displays. In doing so, any adjustments made to heading bugs, altitude select, airspeed bugs, as well as the barometric pressure setting are automatically synced from the G500 TXi or G500 displays to the G51. Flight director and autopilot mode annunciations from the GFC 500 can also be viewed across all displays, including G5. Over 600 aircraft are approved for the installation of G5 as a standby flight instrument alongside the G500 TXi or G500 flight displays.

Other software updates include:

• GFC 500: Now approved for G500 TXi and G500-equipped aircraft

• Course deviation indication (CDI) and VDI preview

• Garmin Pilot and Engine Information System (EIS) analytics

• New TXi display orientations, configurations and capabilities

• GTN 650/750 series enhancements

These software updates are available immediately from Garmin Authorized Dealers for hundreds of aircraft makes and models. These updates are available from Garmin at no charge. A dealer installation charge may apply. Garmin avionics are supported by Garmin’s award-winning aviation support team, which provides 24/7 worldwide technical and warranty support.
