G5 Electronic Flight Instrument Backup or Primary Flight Instrument with Optional Autopilot Capability

At first glance, the G5 electronic flight instrument may look like just a backup indicator, but upon further investigation, you’ll quickly realize it’s much more than that. The G5, designed by Garmin “Team X” engineers, offers homebuilders a simple, cost-effective solution as either a standalone flight display or a backup flight instrument in experimental/light sport aircraft.

Boasting a bright, easy-to-read 3.5-inch LCD color display, it was designed to fit a standard 3-1/8 inch instrument cutout, making it an easy replacement option for traditional steam gauge indicators. It consolidates aircraft attitude, vertical speed, altitude, airspeed, slip/skid, and baro setting into a convenient package. A built-in GPS receiver will also provide a highly accurate ground speed and ground track. In addition to the redundant capabilities it provides as a backup, the G5 can also be utilized as a fully integrated, dissimilar backup flight instrument for G3X, G3X Touch or other EFIS glass cockpits. It can provide standalone backup autopilot control that will allow coupled GPS approaches to be flown or continued in the event of a primary display loss. And power won’t be an issue for the G5, with an optional battery backup that can sustain the instrument for up to four hours of emergency power.

G5 Highlights:
  • Bright, 3.5 inch sunlight readable display.
  • Approved as a primary source for aircraft attitude and turn coordination.
  • Secondary source for altitude, airspeed and vertical speed.
  • Simple installation-integrates with aircraft's existing pitot/static system.
  • Configurable V-speed references, baro setting, and selected altitude.
  • Altitude Alerter.
  • Fit's standard 3 1/8" instrument hole. 

Seamless Cockpit Integration

The G5 offers EAB/LSA aircraft owners a cost-effective path to add a primary or backup flight instrument to their cockpits, which combines essential flight information on an easy-to-read display. Suitable for installation in place of a standard 3-1/8-inch (79.4 mm) flight instrument, the G5 can easily be integrated into an EAB/LSA cockpit. An optional 3-hour backup battery can be included with a G5 installation to provide pilots with added assurance in the event of an aircraft electrical failure. The easy-to-install G5 flight instrument measures 3 inches in depth when paired with the backup battery and 2.1 inches without the battery. Installation is further simplified as the G5 incorporates pitot and static inputs that easily integrate with the aircraft’s existing pitot/static system. The G5 includes a built-in GPS antenna; however, an external GPS antenna is optionally available if needed.

Even More Capabilities when Paired with G3XTM Systems

The fully integrated G5 electronic flight instrument serves as a dissimilar flight instrument when paired with G3X and G3X TouchTM glass flight displays. In the unlikely event of a G3X ADAHRS failure, the G5 doubles as a redundant ADAHRS source, which can supply the appropriate air data, attitude and heading information to G3X displays. Further expanding its redundant capabilities, autopilot mode annunciation can also display on the G5 flight instrument in the event of a G3X display failure. G3X customers can also leverage the existing G3X magnetometer for heading information, alleviating the need to calibrate and install a separate magnetometer. Pilots who have configured airspeed bugs within their G3X system will notice the same airspeed configurations are displayed on the G5. Depending on ambient cockpit lighting, the G5 display automatically dims and brightens independently from G3X to ensure the display can be easily viewed in all lighting environments. A dedicated rotary knob allows for easy adjustments to altitude and heading bugs as well as barometric altitude settings, which automatically syncs with the G3X or G3X Touch flight displays. 

Simple, Standalone Primary Flight Instrument with Autopilot 

Further expanding the utility of a standard backup display, the G5 electronic flight instrument can be paired with the GMC 307 or GMC 305 autopilot mode controllers and GSA 28 autopilot servos to serve as a standalone autopilot solution, delivering a simple and cost-effective avionics suite. When paired with these systems, G5 displays autopilot mode annunciation alongside primary flight instrumentation. Additionally, if paired with a Garmin portable such as the aera® 660 or aera 796/795, the portable can easily be connected via the serial port on the G5 to allow the autopilot to couple laterally to a flight plan and vertically to a VNAV descent profile. With or without a G3X display, the G5 retains the capability to provide backup or standalone autopilot functionality, including the ability to fly coupled GPS approaches when paired with a compatible IFR navigator. Additional autopilot modes are selectable from the GMC 307 and GMC 305, including heading, pitch, roll, altitude hold, vertical speed hold and airspeed hold. Additionally, Level Mode is supported, which engages the autopilot to bring the aircraft to level flight.
