Garmin Dual G5 Stack

Garmin Dual G5 Stack. Modernize your cockpit with this Garmin Dual G5 certified EFIS stack, a complete installation-ready system that delivers digital precision, dependable solid-state performance, and dramatically improved situational awareness. Designed as a certified upgrade for legacy instrument panels, this package includes both the Garmin G5 Primary Flight Display (PFD) and the Garmin G5 Horizontal Situation Indicator (HSI)—a powerful combination that replaces aging mechanical instruments with modern, high-resolution displays built for real-world flying.

This dual-stack configuration is an excellent choice for both IFR and VFR aircraft, providing a clean panel layout, strong redundancy, and enhanced safety. With bright, crisp screens and highly responsive performance, the Dual G5 setup makes scanning easier, improves workload management, and supports better decision-making in demanding weather and busy airspace.

Even more importantly, this offering includes the supporting components required to unlock full system capability—including the GMU-11 magnetometer, GAD-29B avionics adapter, complete installation kit, and certified components with Loadable Part Media (LPM)—making it a premium solution for avionics shops and owners planning a serious panel upgrade.

Garmin G5 PFD benefits:

• Smooth digital attitude performance
• Clear presentation of airspeed and altitude
• Excellent readability in all lighting conditions
• Solid-state reliability vs. mechanical gyros

Garmin Dual G5 Stack

Garmin G5 HSI benefits:

• Modern navigation display and heading guidance
• Clean CDI/HSI presentation for IFR procedures
• Ideal pairing with Garmin navigators for precise tracking
• Includes backup battery for added redundancy

This setup creates a clean, professional digital panel feel while improving reliability and reducing dependence on older mechanical systems.

No Vacuum System Required – Solid-State Reliability

One of the greatest advantages of the Garmin G5 platform is the ability to remove (or reduce reliance on) vacuum-driven instruments. Solid-state EFIS technology is preferred for modern panels because it provides:

• Increased reliability compared to vacuum systems
• Reduced maintenance requirements
• Better long-term performance stability
• Modern redundancy for IFR operations

For aircraft owners modernizing older panels, eliminating vacuum system dependency is one of the most valuable upgrades available.

Full Integration Support With Autopilots and Garmin Navigators

The Garmin Dual G5 system is designed to integrate smoothly with popular avionics configurations. When paired with Garmin navigation equipment and compatible autopilot systems, the Dual G5 stack becomes a powerful cockpit enhancement for approach flying, enroute navigation, and workload reduction.

Integration benefits include compatibility with:

• Garmin GTN navigators
• Garmin GNS navigators
• Many autopilot systems (when properly configured)
• ARINC-enabled systems through included adapter support

This makes the package particularly valuable for IFR aircraft requiring modern guidance and digital redundancy.
