A BendixKing GPS software update is an important maintenance task that helps ensure your avionics system operates smoothly, reliably, and as designed by the manufacturer. Unlike navigation or map updates, which refresh flight data, a software update improves the internal operating logic of the GPS unit itself. These updates can enhance system stability, fix known issues, and sometimes add new features or compatibility improvements. This article explains what a BendixKing GPS software update is, why it matters, and how to carry it out correctly.
What Is a BendixKing GPS Software Update?
A BendixKing GPS software update modifies the internal operating software—often referred to as firmware—of the GPS unit. This software controls how the system boots, processes inputs, communicates with other avionics, and displays information to the pilot. While navigation databases tell the GPS what to display, the software determines how the system functions.
Software updates are typically released by BendixKing or Honeywell to address performance issues, correct bugs, improve system reliability, or ensure compatibility with updated navigation databases and other avionics. These updates are not issued on a fixed cycle like AIRAC navigation updates and are usually installed only when recommended or required.
Why a BendixKing GPS Software Update Is Important
Keeping your GPS software current provides several key benefits:
Improved system reliability
Software updates often resolve known issues such as system freezes, slow startup times, or unexpected reboots. Installing the latest version helps ensure stable operation.
Enhanced compatibility
As navigation databases, displays, and connected avionics evolve, software updates help maintain proper communication between systems.
Performance improvements
Some updates optimize processing speed, improve screen responsiveness, or enhance overall system efficiency.
Safety and compliance
In certain cases, a software update may be required to correct behavior that could affect navigation accuracy or system alerts, making it an important safety consideration.
Manufacturer support
Running outdated software may limit manufacturer or service center support, especially if issues arise that have already been addressed in newer versions.
BendixKing GPS Units That May Require Software Updates
BendixKing has produced a wide range of GPS and avionics systems, including units in the KLN and KMD series, as well as integrated navigation and display systems. Not all units require frequent software updates, and some older systems may have limited or final software versions.
Because software update procedures vary by model, it is essential to identify the exact GPS unit installed in your aircraft and verify whether a newer software version is available or recommended.
What You Need Before Updating GPS Software
Before performing a BendixKing GPS software update, make sure you have the following:
- The exact model and part number of the BendixKing GPS unit
- The correct and approved software version for that model
- An authorized update tool, data loader, or transfer device
- Access to the manufacturer’s update instructions or service bulletin
- Reliable aircraft power or an external power supply
Unlike navigation updates, software updates may require assistance from an avionics technician or authorized service center, depending on the system and certification requirements.
How to Perform a BendixKing GPS Software Update
The software update process varies by unit, but the general steps typically include:
- Check the current software version
Power on the GPS unit and access the system information or maintenance page. Record the currently installed software version. - Confirm update availability and applicability
Review manufacturer documentation or service bulletins to determine whether a newer software version applies to your unit and configuration. - Prepare the update equipment
Load the approved software onto the authorized data loader or update device following BendixKing instructions precisely. - Ensure stable power
Confirm that aircraft power is stable or connect an external power source. Power interruptions during a software update can damage the unit. - Initiate the software update
Follow the step-by-step update procedure for your specific GPS model. Some updates begin automatically, while others require menu selections or maintenance-mode access. - Allow the update to complete without interruption
Do not cycle power, remove devices, or operate other avionics during the update process. - Verify successful installation
After completion, confirm that the new software version is displayed correctly and that the system boots and operates normally.
Common Mistakes to Avoid
Software updates are more sensitive than database updates, and errors can have serious consequences. Avoid the following:
- Installing software intended for a different GPS model
- Interrupting power during the update process
- Skipping manufacturer instructions or service bulletins
- Attempting updates without proper authorization or tools
- Failing to test the system after the update
When in doubt, consult an authorized BendixKing service center or avionics technician.
Best Practices for Managing GPS Software Updates
To manage BendixKing GPS software updates effectively:
- Update software only when recommended or required
- Keep records of installed software versions
- Combine software updates with scheduled maintenance when possible
- Perform a full system check after updating
- Coordinate with avionics professionals for complex or certified systems
These practices help ensure updates are completed safely and correctly.
Conclusion
A BendixKing GPS software update plays a crucial role in maintaining system stability, performance, and long-term reliability. While not required as frequently as navigation updates, software updates address underlying system functionality and help ensure compatibility with evolving avionics and databases. By following proper procedures and manufacturer guidance, pilots and operators can confidently keep their BendixKing GPS systems operating at peak performance.
