Live the Suite Life

All the capabilities you want in a true “glass cockpit” are brought together in the G3X flight display system. Designed specifically for experimental/kitplane and light sport panels, this scalable system lets you grow as your needs and budget allow.

This easy-to-install suite can contain up to 3 redundant PFD/MFD configurable displays, all of which contain built-in GPS and big, bright, sunlight-readable 7″ high-resolution WVGA screens. G3X provides full PFD attitude/directional guidance along with electronic engine gauges, terrain/obstacles alerting, georeferenced FliteCharts and SafeTaxi airport diagrams. ADS-B “In” with traffic and weather, ADS-B “Out” transponder and angle of attack sensor can all be added easily. An affordable Garmin autopilot system is also available with advanced features such as coupled approaches and auto-trim as well as flight director, indicated air speed hold and straight-and-level button when installed with an optional control panel.

You can choose a single- or multi-display configuration with separate PFD and MFD displays — or you can even add a third co-pilot’s display, if desired.

One System — Many Solutions

The integration and versatility provided by the G3X electronic flight displays make it easy to customize the ideal panel layout for your aircraft. You can start with a single display — or use as many as 3 displays — to fit the space, avionics stack and budget available. Here are just a few examples of what’s possible and practical in a G3X installation.

Single Display

The versatile G3X panel-mount glass displays work like building blocks, allowing you to grow your system to fit your needs and budget. You can start with a single display that combines full PFD attitude/directional guidance with electronic engine monitoring and moving map MFD capabilities.

Dual Display

Want a 2-screen flight deck layout with separate PFD and MFD displays? That’s an easy upgrade with G3X. You get a large-format attitude and heading display, paired with your moving map and engine gauge data. A built-in Garmin network interface allows for full reversionary capability on either screen.

Triple Display

The Garmin network interface allows for a maximum of 3 displays to be interlinked in your panel. You can use the third unit as an optional second MFD to display even more data at once — such as dedicated engine information and moving map.

Combine Simplicity with Sophistication

The multitasking Garmin displays that comprise your G3X suite are scaled to fit the panels (and price ranges) of most experimental/kitbuilt and LSA.

Each display features a large 7″ high-resolution WVGA screen, built-in high-sensitivity WAAS GPS receiver, rotary joystick cursor control for data entry, redundant power inputs and soft keys for mode selection. There’s a front-loading SD™ card slot for easy updating of software and databases. Plus, a built-in aviation basemap helps provide realistic visual reference — identifying cities, roads, rivers, lakes and other guidepoints. You can choose topographic VFR or airway-style IFR map modes. And there’s also a built-in terrain elevation database that uses color coding to alert you as you approach potentially hazardous terrain. Both overhead and vertical profile views of this data are graphically depicted on the terrain page.

Each G3X system comes with the following items:

  • 1 or more displays
  • Magnetometer, which determines the aircraft’s magnetic heading
  • Outside air temperature probe

Add an Affordable Automatic Flight Control System (AFCS)

All it takes is the addition of our affordable GSA 28 “smart” servo units to give your G3X a range of autopilot capabilities similar to those provided by our top-end flight control technology. You have the option of purchasing 1 servo (roll only) or 2 servos (pitch and roll) to add the level of capability you want. Even better, the Garmin servo provides a built-in interface to drive a customer-supplied trim servo at no extra cost.

When the autopilot is off, the servo provides speed scheduling for the manual trim commands. When the autopilot is on, the servo adjusts to constantly keep the aircraft trimmed. It also features a gear train with engagement clutch and the ability to back drive the brushless DC motor, providing multiple levels of safety without the use of a shear pin. Plus, servo software updates are completed over the CAN bus using the G3X SD card, eliminating the need to send the servo back to the manufacturer for updates.

The optional GMC 305 or GMC 307 control panel is a dedicated interface unit that provides advanced autopilot modes such as indicated airspeed hold, independent flight director and third axis yaw damper (when installed with appropriate servos). A control wheel integrated into GMC 305 and GMC 307 makes for easier pitch, vertical speed and airspeed adjustments. Plus, for added safety, the panel’s advanced LVL mode button commands the autopilot to help restore your aircraft to straight-and-level flight.

The control panels also provide redundant control of the G3X autopilot for LVL mode, pitch/roll hold modes, altitude hold mode and control wheel steering (CWS). Installation of the servos is simple and straightforward, with industry-standard servo mounting kits available — as well as airframe-specific versions for the popular Van’s RV series (RV-4/6/7/8/9/10 models).

With installation of the G3X autopilot servos, you’ll also obtain our ESP-X to provide assistance in maintaining the aircraft in stable flight. When you exceed user-selected pitch, roll or airspeed limitations while hand-flying the aircraft, ESP-X provides gentle nudges on the flight controls to lessen the aircraft’s pitch attitude or bank angle — and that correcting force grows stronger as those exceedances increase. In addition, you’ll see visual cues on the G3X display indicating that ESP-X is engaged; yellow chevrons provide visual pitch guidance, and configurable roll-limit indicators indicate where ESP-X engages to provide bank guidance. As you take corrective action, ESP-X fades, and it turns off when you return to a normal flight envelope.

Conversely, if the system activates for more than 15 seconds — for example, if you become incapacitated — the autopilot engages with the flight director in level mode, bringing the aircraft to level flight until you command otherwise. While ESP-X will not recover an aircraft in all in-flight situations, the system does provide your experimental and LSA with an extra safeguard.

But ESP-X goes beyond providing pitch and bank envelope protection to also offer high- and low-airspeed protection. In a high-airspeed situation, ESP-X engages the G3X autopilot servos to increase your pitch attitude, while built-in parameters further prevent the aircraft from exceeding G limit load factors. In low-airspeed situations, ESP-X engages to provide a gentle pitch-down force to reduce the likelihood of a stall — and ESP-X automatically disables when the aircraft is operating within 200’ of the ground.

In addition, pitch, roll and airspeed envelope protection parameters are all customizable, and for flight training or aerobatics, you can easily inhibit ESP-X within the AFCS menu of G3X or with an optional switch in the panel.

Attitude Awareness

In place of sensitive mechanical gyro instruments, the G3X system uses the latest in GPS-aided ADAHRS. Based on solid-state technology derived from our popular certified G1000® system, ADAHRS provides accurate and reliable referencing of aircraft attitude, heading, rate, vector and acceleration data. Because ADAHRS is independent of the magnetometer, it can be mounted in any of 16 positions without special magnetometer considerations. For additional redundancy, the G3X system optionally supports multiple ADHARS, sharing the input of a single magnetometer and outside air temperature probe or with a redundant magnetometer and probe if preferred.

Rich, Interactive Map and More

G3X contains a powerful, rich and detailed moving map display. If you’ve ever wondered at any given moment how far away upcoming airspace, inclement weather, traffic or anything on the moving map was, G3X makes it a cinch! Simply press the knob, and scroll anywhere on the map, and — using your current position — G3X displays the distance, bearing and time to that location on the map as well as the elevation and GPS coordinates of that location.

Other powerful features include an “Always On” bearing pointer to the nearest airport, extended runway centrelines, easy creation of user waypoints, altitude alerting tones when leaving the indicated bugged altitude, display of pilot-defined checklists and flight and engine data logging of up to 1,000 hours on a single 2 GB SD card.

Engine Instruments

Configurable EIS displays of engine, fuel and systems data can be accessed and monitored on G3X via the system’s ADAHRS remote sensor unit. Engine sensor kits priced as low as $299 are available for popular models of Lycoming, Continental, Rotax and Jabiru engines.

Synthetic Vision

With our SVX™ synthetic vision technology for the G3X flight display system, you’ll always know what lies ahead — even in solid IFR or night time VFR conditions. Using sophisticated graphics modelling, SVX provides a 3-D “virtual reality” perspective for enhanced situational awareness. Synthetic vision displays terrain using different shades of colour and even includes streams, lakes and large bodies of water. Even more, it displays obstacles, traffic (optional), the airport environment that includes airport signposts and the runway. For additional awareness, your route is outlined with “windows” on the PFD screen. This virtual “highway in the sky” varies in size to depict the flight path in perspective, making it easy to visualize en route legs, course intercepts, final approach courses, runway thresholds and more.

SafeTaxi Diagrams

When your aircraft touches down, our built-in SafeTaxi airport diagrams are there to help you confidently navigate many U.S., Canadian and European airports. You’ll see a depiction of your aircraft’s exact location overlaid onto taxiways, runways, hot spots, hangars and other airport facilities.

Terrain and Obstacles

In addition to the worldwide Garmin land basemap that helps identify cities, roads and bodies of water along your flight path, the G3X also provides a built-in database of both terrain elevation and obstacles that overlay on the main moving map page. And, based on the aircraft’s current altitude, the dedicated terrain page helps to depict terrain and obstacles of concern. The terrain page can be displayed using a 2-D map, profile view or both. While not directly focusing on the display, both visual and audible alerts help provide an automated warning to the pilot. Even more, G3X provides a 500’ callout for additional confirmation while on approach for landing at the destination airport.

FliteCharts Terminal Procedures

The G3X system comes preloaded with our georeferenced FliteCharts, which displays your position on AeroNav–format terminal procedures, including IFR approach plates for thousands of U.S. airports. Optional georeferenced ChartView is also available for those who prefer Jeppesen-style charts (subscription required).

Reversionary Mode

If your installation includes a separate PFD and MFD, you’ll have additional reversionary backup should a failure of either display occur. In reversionary mode, the remaining GDU combines critical flight instrumentation with engine readouts and navigation information in a single-screen consolidated presentation.

Advanced Avionics Integration

G3X is natively integrated with our navigators, including the popular new GTN™ series and GNS™ series avionics as well as GTR/GNC® series radios. This brings advanced integration — including display of the flight plan — from the GTN/GNS navigators as well as more detailed leg instructions such as holds and procedure turns.

In addition to advanced integration with Garmin navigators, G3X will also command our G3X autopilot so you can fly like the pros. G3X provides pitch and roll steering commands to the autopilot. And all this information is displayed and easily controlled using the soft keys and knobs on the PFD. It even flies a preset vertical navigation (VNAV) profile, which makes getting down to the desired altitude and distance from the airport — like the traffic pattern — a cinch. Even better, when combined with a GTN or GNS navigator, this tight integration provides capability similar to the GFC™ 700 system, allowing pilots to couple the autopilot to fly the entire approach down to minimums and even fly coupled go-around procedures.

ADS-B Weather

Gain access to subscription-free aviation weather information on your G3X with the addition of a compatible ADS-B receiver. The remote-mounted device features ADS-B “In” technology that allows it to receive Flight Information Service-Broadcast (FIS-B) weather information over the FAA’s 978 MHz Universal Access Transceiver (UAT) uplink. Easily access and display animated NEXRAD radar, METARs, TAFs, winds and temperatures aloft, PIREPs, NOTAMs and more right on your G3X display.

ADS-B Traffic

When equipped with our compatible ADS-B receiver’s, G3X can receive and display ADS-B position reports directly from other aircraft in your vicinity. Because the FAA permits ADS-B broadcasts on 2 frequencies (978 UAT and 1090 ES), GDL® 39 contains both receivers so you can see a comprehensive view of all ADS-B “Out”-equipped targets. In addition, GDL 39 can receive Traffic Information Service-Broadcast (TIS-B) information that allows you to view the same dynamic traffic picture as ATC ground controllers. TIS-B information is available if your aircraft is either participating with an ADS-B “Out” solution or within a certain range of another ADS-B “Out” participating aircraft in a service area. TargetTrend™ technology provides an easy-to-interpret picture of aircraft trajectories so you can better predict which may converge on your own, while TerminalTrafficTM technology supports the display of ADS-B “Out”-equipped surface targets.

Angle of Attack

Our angle of attack (AOA) system provides accurate, real-time measurement of wing performance to provide both audible and visual stall margin indication to the pilot. The GAP 26 pitot and AOA probe is available with unheated pitot, with pilot-controllable heated pitot or with automatic temperature regulating pitot that helps protect against in-flight icing, helps save power and maintains a lower surface temperature when operating in stagnant air. Requires the GSU 25 ADAHRS for interface capability.
