Garmin announced at the Aircraft Electronics Association's International Convention and Tradeshow, which is ongoing this week at the Palm Springs Convention Center in Palm Springs, California, that it has achieved FAA certification for installations of its highly acclaimed G3X Touch system, originally designed for the experimental market, in Part 23 aircraft. The company also achieved TSO authorization for two new ADS-B transponders: the GTX 335D and GTX 345D.

The G3X Touch certification covers more than 500 different types of single-engine airplanes. Two versions are offered: a 10.6-inch and a 7-inch display, both of which can be configured as a PFD or MFD depending on the customer’s needs. For smaller panels, the system can be used as a standalone PFD/MFD or, if more space is available, several combinations can be configured with multiple screens.

G3X can be manipulated through the touch screen or dual concentric knobs. In addition to providing synthetic vision, which shows terrain and obstacle imagery, and depicts the runway environment, the G3X functions as a VFR navigator. It can also display VFR sectionals and IFR enroute charts as well as geo-referenced instrument approach charts, and it can be connected with Garmin’s IFR navigators for IFR navigation. Wireless connectivity is included, enabling wireless flight plan transfer, and sharing of traffic, weather and back-up attitude data with a portable tablet.

G3X can also integrate engine information and comm radios, and it can communicate with Garmin’s G5 electronic flight instrument for backup data and GFC 500 autopilot, which can be used to fly coupled instrument and visual approaches.

The GTX 335D transponder offers ADS-B Out coverage while the GTX 345D provides both ADS-B In and Out. Features include Garmin's TargetTrend and TerminalTraffic, and verbal traffic alerts can be provided by connecting the transponders to the airplane's audiopanel.

The new transponders can connect to a variety of panel mounted and portable platforms, including the G1000 and G3000 integrated avionics systems. Remote versions of the transponders are available. By the end of the second quarter of this year, Garmin expects to have an updated Aircraft Model List for the STC installation for hundreds of aircraft models. Pricing for the GTX 335D is $6,495 while the GTX 345D costs $7,995.
