This article explains how to update BendixKing GPS navigation, why updates matter, and what you should consider before and after performing updates. The guide is written in simple, clear language to help pilots, aircraft owners, and aviation technicians handle GPS updates confidently.
Importance of Updating BendixKing GPS Navigation
Aviation navigation relies on precise and current data. Airspace boundaries, approach procedures, airport layouts, and navigation aids continuously change. If your BendixKing GPS is running outdated software or navigation database, the accuracy of your flight planning and in-flight guidance can be compromised.
Updated GPS data helps ensure the following:
Improved Flight Safety
Up-to-date navigation charts allow pilots to fly confidently through current airways, restricted zones, and updated procedures. This reduces the risk of entering incorrect airspace or following obsolete routes.
Reliable Situational Awareness
GPS updates include terrain data, obstacles, waypoints, and airport changes. With current information, pilots maintain better situational awareness during all phases of flight.
Enhanced System Performance
Software updates often come with improvements in system performance, bug fixes, and new features. Keeping your device updated ensures it operates smoothly and efficiently.
Compliance with Aviation Requirements
Many aviation regulatory bodies require aircraft to maintain current navigation data to ensure safe operations. Updating your BendixKing GPS helps keep the aircraft compliant with regulations and industry standards.
Types of Updates Available for BendixKing GPS Systems
BendixKing GPS systems typically support two categories of updates:
Navigation Database Updates
These include airport charts, airspace boundaries, terrain data, flight routes, SIDs, STARs, approaches, and navaids. Navigation databases update periodically to reflect the latest aviation changes.
Software and Firmware Updates
These updates enhance the system’s usability, stability, and functionality. They may include improvements to the user interface, bug fixes, or new features specific to the device model.
Understanding which type of update you need is the first step to ensuring your GPS system stays reliable and accurate.
Preparing for a BendixKing GPS Navigation Update
Before beginning the update process, proper preparation helps avoid complications. Here are key things to keep in mind:
Check Your Device Model
BendixKing offers various GPS models, each with its own update process. Identify your device model, such as the KSN 770, KLN 89B, or KLN 94, to follow the correct procedure.
Verify Subscription Status
Navigation data updates usually require an active subscription. Make sure your subscription for navigation data or databases is current. Without a valid subscription, downloads may be restricted.
Ensure Compatible Hardware
Some BendixKing units require specific update cards, memory modules, or dedicated update tools. Confirm that you have the necessary hardware before starting.
Back Up Existing Data
Although rare, update interruptions can affect stored flight plans or user-defined waypoints. Backing up data helps ensure you can restore important information if needed.
Power Source Stability
Make sure your aircraft or the device is connected to a stable power source while updating. Interruptions during installation could cause system errors.
How to Update BendixKing GPS Navigation
The exact steps depend on your model, but the update process generally follows a similar pattern. Below is a detailed guide that covers the essential steps for most BendixKing GPS units.
Downloading the Navigation Update
Visit the Navigation Data Provider
BendixKing GPS systems typically use aviation database providers to supply updated charts and data. Access your account through the provider associated with your system.
Select Your GPS Model
Choose the correct BendixKing model to ensure the update you download is compatible with your system. Selecting an incorrect model can result in installation failure or database errors.
Download the Latest Navigation Database
Once you have selected your device, download the latest navigation data package. These files are usually downloaded onto a computer before being transferred to the GPS device or memory module.
Preparing the Update Card or Module
Many BendixKing systems require a data card or memory module to perform updates.
Format the Update Card
If required, format the card according to the device’s specifications. Follow the recommended formatting guidelines to ensure compatibility.
Transfer the Update Files
Copy the downloaded navigation data files onto the update card. Make sure all files are transferred correctly and the card is safely ejected from your computer.
Installing the Update on the GPS Unit
With the update card prepared, it is time to install the update onto the BendixKing GPS system.
Insert the Update Card
Insert the card into the correct slot on the GPS unit. Some systems require powering off the device first, while others can accept the card during operation.
Power On the GPS System
Turn on the GPS system. The unit should automatically detect the update card and prompt you with an installation message.
Start the Installation Process
Follow the on-screen instructions to begin the installation. This process may take several minutes, depending on the size of the update.
Wait for Completion
Avoid disturbing the device during the update. Interruptions can lead to installation errors or data corruption. Once complete, the system will either reboot automatically or display a confirmation message.
Verifying the Update
After installation, it is crucial to verify that the update was successful. This ensures your GPS system is running the latest data and functioning correctly.
Check the Database Version
Navigate to the GPS system’s settings or information page to verify the current database version. Compare it with the version you downloaded to ensure accuracy.
Test Basic Functions
Browse through the menus, waypoints, maps, and routes to ensure everything is loading correctly. Check for missing data or display issues.
Load a Test Route
Create a simple flight plan to test functionality. Confirm that navigation aids, procedures, and routes load as expected.
Common Issues and How to Avoid Them
While updating BendixKing GPS navigation is usually a smooth process, issues can still arise. Here are common problems and how to prevent or resolve them.
Update Card Not Recognized
If the GPS does not detect the update card, the card may not be formatted properly or the files may not be placed correctly.
Corrupted Files
If the installation fails, re-download the update files to ensure they were not corrupted during download.
Power Interruption
If the update is interrupted due to loss of power, restart the device and attempt the installation again. In rare cases, professional servicing may be required.
Wrong Model Selected
Downloading the database for an incorrect model is a common mistake. Always double-check the device model before downloading updates.
Tips for Maintaining Updated Navigation Data
Keeping your BendixKing GPS updated should be part of your regular flight preparation routine. Here are tips for staying current:
