Part# 11-14312
MFR Model# 010-01485-01


Designed by our dedicated “Team X” engineering group specifically for the experimental amateur-built (EAB) and light sport aircraft (LSA) markets, the affordable G5 electronic flight instrument delivers exceptional performance, reliability and ease of installation as an all-in-one backup or primary “glass cockpit” display. The crisp, sunlight-readable 3.5” LCD fits into a standard 3-1/8” round cutout, taking up just a fraction of the space and weight previously required by conventional gyro-based instruments.

G5 has 2 pilot-selectable main page formats: a PFD page and a DG (directional gyro) or HSI (horizontal situation indicator) page. VHF or GPS navigation inputs are required to drive the HSI display; for GPS interface, an optional GAD™ 29 navigation data adapter is required. By combining visual cues and data readouts once scattered across a myriad of instruments, G5 makes flight information easier to scan — so pilots can respond more quickly and intuitively to any inflight situation.

Rock-solid Attitude Reference
When configured as a primary attitude indicator, G5 uses solid-state AHRS reference to provide smooth, steady and reliable horizon-based pitch and roll indications. In addition to aircraft attitude, G5 will also support display of airspeed, altitude, vertical speed, slip/skid, turn rate, configurable V-speed references, barometric setting and selected altitude — as well as visual alerts upon arriving at a preselected altitude. A built-in GPS receiver and antenna (with an option for external GPS antenna connection) provides highly accurate groundspeed and ground track readouts. Plus, a dedicated rotary knob on the unit allows for easy adjustments to altitude bugs and barometric pressure settings.

Gain a Clearer Sense of Direction
To provide even more situational awareness, the G5 instrument can also function as a DG or HSI in your panel. When paired with an affordable GMU 11 magnetometer and select VHF Nav/Comms or GPS navigators (interfaced with optional GAD 29 navigation data adapter), G5 can serve as your primary reference source for magnetic heading, VOR/LOC guidance and/or GPS course guidance — as well as providing distance and groundspeed indications. The unit displays both vertical and lateral GPS/VOR/LOC course deviation when available (additional equipment may be required). And you can use the G5 instrument’s rotary knob to easily make and adjust course selections — or to control heading bug settings in DG installations. Because the GMU 11 is connected to the CAN bus network, a single magnetometer can supply heading information to 2 G5 units simultaneously.

Dual Displays Double Your Options
By installing dual G5 displays in your panel, you not only gain dedicated instruments for attitude reference and directional gyro/HSI guidance — you also gain the advantages of backup redundancy with dual ADAHRS and reversionary display capability. In such installations, a secondary G5 can revert to display attitude information (consolidated with heading indication) in the unlikely event of a failure in the primary attitude indicator position. For added “get home” protection, each G5 display is available with an optional backup lithium-ion battery, which can provide up to 4 hours of emergency operation in case of an aircraft electrical outage or shutdown. And if you use one of our aera® series aviation portables¹ as a backup, you can fly with battery-powered moving map navigation guidance — as well as the G5 instrument’s flight display information — to make that aircraft electronics outage virtually a non-event.

It’s Even Better with G3X
When used as a backup instrument for your G3X, G3X Touch or other compatible glass display system, G5 provides a full range of supplemental EFIS capabilities. So, if needed, it can be used to maintain the majority of your flight display and autopilot control functions — including the ability to fly coupled GPS approaches. G5 will also provide backup ADAHRS reference to the primary displays. So whatever happens, with a G5 electronic flight instrument in your system, you can count on a wider range of options in virtually any shutdown scenario.

Stand-alone Flight Instrument with Autopilot
G5 may be installed with a GMC 305 or GMC 307 autopilot control panel and up to 3 GSA 28 smart servos to perform as a stand-alone flight instrument with integrated autopilot functions. In addition, the GTN™ 750/650 series2 (and legacy navigators2) or a Garmin portable GPS such as aera 660, aera 795 or aera 796 may be connected to the serial port on G5, enabling the autopilot to couple laterally to the flight plan and vertically to support VNAV descents to pattern altitude. Other lateral and vertical autopilot modes selectable from GMC 305 or GMC 307 include heading, pitch, roll, altitude hold, vertical speed hold and airspeed hold. Even the control panel’s level (LVL) mode button is supported to engage the autopilot and restore the aircraft to level flight at the press of a button.

BE ADVSED !!! The Garmin G5 unit is exactly what I wanted and needed to to replace a failed standby HSI. It wasn’t clear that the standard mounting hardware was not included wit the G5 unit. It was not listed in the accessories section of the ad, which displays alternate mounting hardware. This resulted in project delay and additional freight charge. Be advised that you need to order the mounting hardware when ordering the G5.

As others have noted, the G5 needs an installation kit since it uses a nonstandard bracket to connect the device to the existing holes of a 3-1/4 cutout. Once installed and plumbed to the pitot static lines, it works great. I dont have a G3X system but do have a GTN650xi, and running a serial line from the 650 to the G5 gives it a full featured HSI display with nav data that can be toggled with the PFD display. So, a nice two-fer surprise when I was mostly interested in having a backup attitude display with its own solid state AHRS.

My uAvionix AV-30-E failed after one year and a half. The LCD panel fade out, pressure altitude skipping values, OAT stop working... Got the G5, quick and easy to install, better features and better price as well. Solid unit. Barometric Altitude adjustment is right there at your finger tips. You have to press nothing before adjusting BAlt, just turn the solid, smooth clicks knob. Awesome feature! Awesome unit. From now on just Garmin on my panel.
