Replace your old gyro with something more reliable

Garmin made big news with the announcement of G5, and it's easy to see why. The compact and cost-effective G5 electronic flight instrument delivers exceptional performance and reliability as a standalone primary source for aircraft attitude information - it's more than a backup. It also displays secondary information, such as airspeed and altitude, to offer enhanced situational awareness. G5 features an economical upgrade path in type certificated fixed-wing general aviation aircraft, accomplished via supplemental type certificate (STC) with a comprehensive approved model list (AML). The safety-enhancing capabilities of G5 revolutionize general aviation by bringing modern attitude reference to thousands of aircraft that would otherwise depend on older, vacuum-driven equipment.


  • Replaces traditional electromechanical attitude indicator or turn coordinator
  • Integrates with your aircraft's existing pitot/static system
  • Bright, sunlight-readable color screen (3.5" LCD)
  • Fits standard 3 1/8" instrument hole for easy installation
  • Includes 4-hour backup battery with status indicator
  • Includes installation kit
  • Approved for VFR and IFR flight

In place of a primary attitude indicator or turn coordinator, the G5 electronic flight instrument is approved for installation — via a Garmin-held STC — for hundreds of certificated fixed-wing aircraft models. Valid for flight under VFR and IFR conditions, G5 is an economical upgrade path for thousands of owners seeking an electrically driven attitude indicator with greater dependability and internal redundancy over vacuum-driven attitude flight instruments. 

Boasting a bright, 3.5-inch sunlight-readable LCD display, G5 is approved as a primary source for aircraft attitude information. Plus, it serves as a secondary source for altitude, airspeed and vertical speed — all in a single instrument. Installation is simple and easy; G5 integrates with the aircraft’s existing pitot/static system and displays attitude, airspeed, altitude, vertical speed, slip/skid, turn rate, ground track, configurable V-speed references, barometric setting and selected altitude as well as visual alerts upon arriving at the pre-selected altitude. Built-in GPS provides GPS-based track and groundspeed information, and a dedicated rotary knob allows for easy adjustments to altitude bugs and barometric pressure settings

Easy installation

Installed in a standard 3 1/8" (79.4 mm) instrument hole, G5 measures 3" in depth and includes a backup battery so it easily integrates into a wide range of aircraft. Installation is further simplified as G5 only needs power, ground, pitot/static and GPS inputs so it also integrates with the aircraft’s existing systems. For aircraft without a compatible GPS position input, an optional GPS antenna is available. As part of the STC, G5 includes a 4-hour backup battery, and pilots can easily reference battery status in the upper left-hand corner of the display. Install kit included with certified G5.

2nd G5 works well
The first G5 that was installed by a well respected avionics shop failed. It would not hold the bank angle (i.e. you could be flying straight & level; but it would show that you were banking). The 2nd one has worked and it's made flying in IMC easier with essentially only needing to scan the G5 for attitude, altitude, coordination, & airspeed info. With the cost of the unit and the installation, I paid $3,900. When linked to my GTN650, I also see my ground track & speed. Very helpful.

Awsome product for the price.
Had a G5 installed, should have bought it at Sporty's, would have saved some money. Instrument works as advertised and was very pleased with its operation. However, review the installation instructions and setup features with due diligence. The shop that installed one did not read the instructions, they did not level the plane as instructed then calibrate the unit.They didn't even know there was a Pilot operated pitch correction (parallax control, like on a vacuum AI) that was forgotten to be turned on. The shop that installed this is a very well known avionics shop but as with anything new they did not read the instruction very carefully and assumed it installed like any other unit. To insure a good installation make sure you are well versed in the product you install.

Does it work with S-Tec autopilots?
A shopper on Sep 21, 2016
BEST ANSWER: Actually, the certified G5 does not drive any autopilots.
Can this be tied into an existing WAAS GPS antenna or does it require a separate antenna installed?
A shopper on Sep 24, 2016
BEST ANSWER: From what I have read only Garmin GNS/GTN WAAS navigators can be used by the G5 negating a separate GPS WAAS antenna.
Is there a Cessna 150M STC available?
Ewalsh on Jan 9, 2017
BEST ANSWER: Looking at the Garmin G5 list of manuals, look at the AML document. The 150M is not listed under the Cessna "Aircraft Make" list. But it is listed on page 8 under the Textron "Aircraft Make".
HI There, is this Item IFR certified for aircraft registered in Europe?
Jerome M on Nov 8, 2016
Do I need a harness?
Philip on Oct 18, 2016
BEST ANSWER: Your shop will create a harness when they install it.
Can a Garmin GTX345 Transponder w WAAS GPS and digital altitude encoder be used with G5?
Timothy on Dec 31, 2016
Do course and glideslope indications (from ILS, VOR or GPS & WAAS outputs from a 430) appear on the G5?
Kevin G on Nov 22, 2016
BEST ANSWER: John is incorrect. Course information is sent to the G5 from a compatable GPS. Hade one recently installed and the 430 w's corse is sent. However it does scale down as with the 430 during a GPS approach.
Does the G5 provide outputs for autopilots like the King KAP150?
Tim on Nov 22, 2016
Can the G5 be used as a backup Attitude Indicator in a Certified Aircraft (IFR)? For example, as a backup to an Aspen Pro PFD.
A shopper on Sep 26, 2016
BEST ANSWER: We've discovered that no, in fact this is only for use as a primary instrument. It cannot be used for backup - sounds strange, but that's the STC.
Are their plans for the certified G5 in the future to have an HSI option?
A shopper on Nov 25, 2016
BEST ANSWER: The install on my certified G5 (delivered by Sportys on the 10th of november) was just finished and I've got the HSI page option in there.
16 - 24 hours to install? Quick and easy installation? Which is it? That would likely far exceed the cost of the device, no?
AdamY on Jan 26, 2017
BEST ANSWER: Quote I got for installation in my C180 is 6-8 hrs. And that includes an antenna. There is no headliner in the plane so that saves some time. Work is to be done this week and I will advise if it exceeds the quote.
Does this unit provide synthetic terrain visualization?
Carl N on Jul 2, 2017
What is the average installation hours?
Thoru Y on Jan 23, 2017
BEST ANSWER: Yingling Aviation at ICT quoted me $2900 for the G5 install. The IA doing my annual estimates 16 hours and my local Garmin approved avionics shop estimates $1500-$2000. Not exactly an "Easy Installation". Still getting quotes as I'm committed to this upgrade.
Liberty XL2 is not included AML list. Does not Garmin G5 install to my airplane?
A shopper on Sep 11, 2019

A shopper on Aug 24, 2019
BEST ANSWER: No, not that I am aware of.

BEST ANSWER: When the unit is registered with Garmin you will be able to print The STC for you specific aircraft.
If the unit it's installed by an A&P, does he or she have to send a FAA 337 form?
Gustavo M on May 17, 2017
BEST ANSWER: Yes in accordance with STC a form 337 must be completed and sent.
Can the G5 replace the vacuum driven attitude indicator on a G1000 Cessna 172S?
J S on May 4, 2017
BEST ANSWER: The G5 is certified as a "Primary" replacement. I do not believe that it can be used to replace the back up indicator. I would contact Garmin to see if the STC covers this installation. They may be contacted at or via phone at 1.866.739.5687.
Why are Lake aircraft ( LA -4) not on the approved model list ?
Al on Jan 23, 2017
BEST ANSWER: I would contact garmin support at 1-866-739-5687. They should be able to answer if there is a reason why these aircraft were not included.

Gilles O on Jan 16, 2017
BEST ANSWER: Acording to the STC it can only be used as a primary instrument, not a standby.

It says it has a battery life of 4 hrs. Does the aircrafts alternator keep the battery recharged or do you have to recharge from an external source?
Jonathan N on Sep 28, 2016
BEST ANSWER: The battery is just for emergency purposes while flying. To answer your question, Yes, the alternator recharges the battery when the plane is running. No external source is needed/available.
