Garmin G5 and Aera 660 Integration Enhances Avionics

I. The Benefits of Connecting G5 with Aera 660: Unlocking Advanced Flight Capabilities

Many pilots wonder about the potential benefits of connecting their Garmin G5 flight display with the Aera 660 portable navigator. By establishing an RS-232 connection between these devices, pilots gain access to several significant advantages:

  • Enhanced Navigation Guidance: The Aera 660 can provide both lateral and vertical (VNAV) navigation data to the G5, enabling the HSI display to show course deviation indicators (CDI) for precise flight path tracking.
  • Intelligent Flight Assistance: With Aera 660 serving as a navigation source, pilots can use the G5's heading selection knob to follow GPS-defined flight paths automatically.
  • Comprehensive VNAV Guidance: The system provides vertical navigation assistance, helping pilots execute smooth descents from cruise altitude to airport elevation with preset descent rates and distances.
II. Connection Methodology: Establishing the Link Between Devices

The connection process between G5 and Aera 660 is straightforward when following these steps:

  1. Prepare an RS-232 connection cable (typically included with the G5 installation kit)
  2. Connect the cable between the G5's RS-232 port and the Aera 660's data interface
  3. Configure both devices to use matching communication settings (typically 9600 baud rate)
  4. Enable the "Navigation Data" option in the G5's settings menu
III. Advanced Applications: Expanding Flight Capabilities

Beyond basic navigation functions, the G5-Aera 660 combination offers several advanced features:

  • Simulated ILS Approaches: The system can simulate instrument landing approaches using GPS-derived guidance
  • ADS-B Integration: When paired with GDL 39/52 series receivers, the system can display traffic and weather information
  • Future Upgrade Compatibility: The configuration supports future integration with GFC 500 autopilot systems
IV. Troubleshooting Common Connection Issues

Pilots may encounter these common setup challenges:

  • Missing Course Deviation Indicators: Verify matching baud rates and enabled navigation data settings
  • VNAV Functionality Issues: Ensure proper VNAV profile configuration in the Aera 660
  • Data Source Conflicts: Avoid connecting multiple GPS data sources to prevent signal interference
V. System Configuration Considerations

For optimal performance, pilots should note these technical details:

  • Dual G5 installations require specific connection strategies to maintain data redundancy
  • The Aera 660 can load approach procedures from the final approach fix (FAF) to the runway
  • Regular software updates for both devices ensure access to the latest features and improvements
VI. Alternative Options: Considering the Aera 760

For pilots considering upgrades, the Aera 760 offers enhanced capabilities including:

  • Complete arrival and departure procedures
  • Advanced RNAV approach capabilities
  • Improved display resolution and size
  • Enhanced autopilot integration
VII. Conclusion

Proper integration of Garmin's G5 flight display with the Aera 660 navigator creates a powerful avionics combination that enhances both situational awareness and flight precision. The system's modular design allows for future expansion while providing immediate benefits to pilots of all experience levels.
