For many small-aircraft owners, the attitude indicator and directional gyro are the first instruments to show their age. The Garmin G5 is a compact electronic flight instrument that drops into that same 3-1/8″ hole and replaces moving parts with a solid-state display. It gives you modern tapes and trend information, reduces reliance on vacuum pumps, and can serve as a stepping stone toward more advanced Garmin upgrades.

Why Pilots Choose the G5
Legacy gyros and vacuum systems were never meant to last forever. Over time, bearings wear, pumps fail and you’re left wondering if the instruments will behave when you need them most — especially in IMC.
The Garmin G5 was designed to be a straightforward answer to that problem. It’s a small, sunlight-readable electronic display that fits where an old round gauge used to live, but provides much more information on one screen. In many aircraft, it’s the most cost-effective way to retire a problem gyro without redesigning the whole panel.
At Top Flight Avionics, we look at the age, condition and repair history of your current instruments, then help you decide if a G5 upgrade makes more sense than sending them out again.
What the G5 Can Do in Your Panel
Primary Attitude Indicator Replacement
Configured as a primary attitude indicator, the G5 provides pitch and bank, plus airspeed, altitude, vertical speed and a slip/skid indicator. You get familiar six-pack information presented on a bright, solid-state display with modern tapes and trend vectors to help you see where the aircraft is going, not just where it is right now.
DG/HSI with Clear Course Guidance
In a directional gyro or HSI configuration, the G5 can display heading, course and navigation information from compatible GPS and nav radios. Instead of dealing with precession and regular resets, you get stable electronic heading data and clear course guidance, including glideslope when paired with the right navigator.
Backup Power and Standby Roles
With an optional backup battery installed, the G5 can continue to provide attitude information for a limited time after an electrical failure. In more advanced Garmin panels, it can also serve as a standby instrument, ready to take over if a primary display ever goes dark. That gives you multiple layers of resilience in a small footprint.
Autopilot Integration Foundation
The G5 can also serve as the attitude source for a Garmin GFC 500 autopilot in many aircraft. This means a G5 install today can be the first step toward a full digital autopilot later, rather than a one-off upgrade that you’ll replace again in a few years.
How the G5 Helps Pilots of Small Aircraft
Safety & Reliability
- Replaces aging mechanical gyros and reduces dependence on vacuum pumps
- Solid-state sensors for more consistent performance over time
- Optional backup battery adds another layer of protection in electrical failures
Workload & Readability
- Modern tape presentation makes altitude, airspeed and vertical speed trends easier to see
- Clear attitude presentation helps in partial-panel or high-workload situations
- Small footprint but big readability thanks to a bright, sunlight-readable display
Upgrade Path & Resale
- Simple way to modernize a legacy six-pack without a complete panel rebuild
- Sets up your aircraft for a possible GFC 500 autopilot or other Garmin upgrades
- Recognizable Garmin equipment can be a plus when it’s time to sell the aircraft
The G5 Works Great with These Garmin Solutions
A G5 is powerful on its own, but it really shines when it’s part of a bigger plan for your panel.
GFC 500 Digital Autopilot A G5 can serve as the attitude source for a Garmin GFC 500 digital autopilot in many aircraft. Together, they create a modern flight control system that reduces workload in both VFR and IFR operations, especially on long trips and during approaches.
Garmin IFR GPS Options (GPS 175, GNX 375, GNC 355) Pairing the G5 with a compact Garmin IFR GPS gives you a clear place to display course and glideslope information for RNAV approaches without the cost or panel space of a larger navigator.
GTN Xi Series Navigators In more complete Garmin panels, a GTN 650Xi or 750Xi can provide advanced navigation while the G5 displays flight director cues and heading/course information. This is a common configuration for owners who want a modern IFR stack without jumping straight to the most complex systems.
Second G5 or GI 275 for Redundancy Some owners choose to add a second G5 or a GI 275 alongside the first G5 to create redundant attitude and heading sources. We’ll help you decide what level of backup makes sense for your aircraft and budget.
Installed and Certified by
Top Flight Avionics and the CERTMAN
G5 installations may look simple, but proper wiring, configuration and integration with your existing instruments are critical. Top Flight Avionics brings decades of experience to each job, making sure your new electronic flight instrument plays nicely with the rest of your panel.
For G5 projects, we:
- Review your current instrument and vacuum system condition
- Confirm the best role for the G5 (attitude, DG/HSI or standby) given your aircraft and goals
- Design and complete the installation, including backup battery if desired
- Configure and test the instrument, and verify it’s properly integrated with your navigators and autopilot (if present)
Through The CERTMAN, we can also handle necessary IFR, VFR and transponder/pitot-static checks so everything is documented after the upgrade.
