The Garmin G5 electronic flight instrument brings new levels of reliability, affordability, system integration and situational awareness to the Garmin G3X™, other EFIS systems or as a standalone primary flight instrument. Replacing traditional mechanical instruments, the G5 can serve as a standalone backup or primary flight instrument for space-saving, all-in-one flight data reference — or as a fully integrated, dissimilar glass primary flight instrument backup for your Garmin G3X or G3X Touch flight displays.

All-glass Backup or Primary Flight Instrument with Optional Autopilot Capability

  • Bright, sunlight readable 3.5" (88.9 mm) LCD color display, sized to fit standard 3 1/8" (79.4 mm) instrument hole
  • Can be used as a standalone flight display or fully integrated, dissimilar backup flight instrument for G3X and G3X Touch or other EFIS glass cockpits
  • Replaces traditional electromechanical backup instruments, combines essential flight information in one easy-to-read display
  • Provides standalone or backup autopilot control, allowing coupled GPS approaches to be flown or continued in the event of a primary display loss
  • In case of aircraft power loss, optional battery backup sustains G5 flight instrument with up to 4 hours of emergency power

All-in-one, One for All
By combining visual cues and data readouts once scattered across a myriad of instruments, the Garmin G5 electronic display makes flight information easier to scan – so pilots can respond more quickly and intuitively to any inflight situation. The Garmin G5 efficiently consolidates all essential situational reference for aircraft attitude, vertical speed, altitude, airspeed, slip/skid, and baro setting. A built-in GPS receiver and antenna (with an option for external GPS antenna connection) provide a highly accurate ground speed and ground track readout. Better still, the complete G5 unit fits into a single 3 1/8" standard instrument cutout, taking up just a fraction of the space and weight previously required by conventional gyro-based instrument displays.

It’s Even Better with G3X
The G5 integrates uniquely with the Garmin G3X and G3X Touch systems to provide even more backup display capability. With G3X system integration, the G5 can provide heading, course deviation, flight director cues, autopilot mode annunciation, turn coordination, glideslope/glidepath, altitude and airspeed bug settings, and more. The G5’s bright, high-resolution QVGA screen lets pilots view all this critical data at a glance. And when teamed with Garmin autopilot servos and the GMC 307 or GMC 305 mode controller interface, the G5 provides a backup or standalone autopilot function. In the event the primary display becomes unavailable, the G5 seamlessly soldiers on, maintaining the majority of autopilot control functions – including the ability to fly coupled GPS approaches. Plus, in the unlikely event that your G3X system’s ADAHRS reference becomes unavailable, the G5 will provide backup attitude information to the G3X displays as well. So, by adding the G5 to your G3X system, you get the benefit of a second attitude source, as well as supplemental flight display and autopilot support.

Standalone Flight Instrument with Autopilot
The G5 may also be installed with a GMC 305 or GMC 307 autopilot control panel and up to 3 GSA 28 smart servos to perform as a standalone flight instrument with integrated autopilot functions. In addition, the Garmin GTN 750/650 series (and legacy navigators) or a Garmin portable GPS such as the aera 660 or aera 795/796 may be connected to the serial port on the 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 the 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.

More Power in Reserve
For the ultimate “get home” option, the Garmin G5 is available with a potent lithium-ion battery (sold separately), which can provide up to 4 hours of emergency operation, should your aircraft ever lose power to the avionics. And if you use one of Garmin’s aera® series aviation portables (sold separately) as a backup, you can fly with battery-powered moving map navigation guidance – as well as the G5’s flight display information – to make that aircraft electronics outage virtually a non-event.

Like The G5 a Lot
After one use, I'm very impressed. My biggest concern was that the display would be too "busy" with so much information, but it's very easy to use and read. I love the way the ground track is displayed in magenta right at the pointer at the top, making it easy to fly a precise instrument approach. All the information is laid out remarkably well, and I felt like I was used to it almost right away. The display is bright and easy to read, even in bright sunlight. I can't rate the durability or reliability, but from what I've seen so far, I highly recommend this instrument.

Do you know for sure if you will have these units by Dec 16 for shipping?
AARECON on Dec 1, 2016
BEST ANSWER: That's the best information we have, but it's not certain. These have been very popular and Garmin is making them as fast as they can.
I have a backup, electric AI that has failed. Can this be installed as a replacement in a certified aircraft as a backup, not primary?
Bruce W on Jan 18, 2017
BEST ANSWER: The STC for this unit is as a primary flight display only.
What does "no harness" mean?
A shopper on Jan 16, 2017
BEST ANSWER: It does not include a wiring harness for installation. We can make one up for an additional charge.
what sensors does it need ?
A shopper on Oct 10, 2018
BEST ANSWER: The absolute minimum is none. Of course, it expects a pitot and static line to measure airspeed and altitude.. It will act as a attitude indicator all by itself. It has a basic GPS receiver built in so it can show ground speed also. I have it connected to a Garmin 650 through an adapter box. This allows it so show full GPS based navigation. Note that for reasons Garmin has not been able to answer, it does not show the VOR/localizer/glide slope.
Is the STC paperwork available for this unit to install it in a certified aircraft?
A shopper on Mar 2, 2020
BEST ANSWER: Yes, when it is registered after it is installed. The installer will print the STC information.
What is the difference between the G5 for certified aircraft and the G5 for experimental aircraft?
A shopper on Oct 20, 2017
BEST ANSWER: The required paper work for the certified aircraft. The units are the same.
Can the altitude be calibrated?
Michael S on Jan 25, 2017
BEST ANSWER: The altitude is calibrated when the unit is installed in the aircraft.
Configuration in metric system: kilometers per hour instead if knots, and meters vs. feet possible ?? Thx
nonee on Jan 24, 2017
BEST ANSWER: The unit is not capable of configured in the metric measurements.
Can the Baro setting be configured in hectopascals ?
A shopper on Jan 23, 2017
BEST ANSWER: The Baro Setting is inches of mercury and can not be configured in hectopascals.
