A BendixKing GPS navigation update is a critical part of maintaining accurate avionics and ensuring safe flight operations. BendixKing GPS systems are widely used in general aviation and business aircraft, and their reliability depends on current navigation data. Updating the navigation database ensures that waypoints, airways, procedures, and airports reflect the latest published information. This article explains what a BendixKing GPS navigation update is, why it matters, and how to complete the process correctly.
What Is a BendixKing GPS Navigation Update?
A BendixKing GPS navigation update refreshes the core navigation database used by the GPS unit to calculate position, routes, and procedures. This database includes fixes, VORs, NDBs, airways, airports, instrument approaches, departures (SIDs), and arrivals (STARs). It is different from a software update, which changes how the unit operates, and different from a map-only update, which affects graphical display elements.
Navigation databases follow the AIRAC cycle, which updates every 28 days. Each cycle reflects changes issued by aviation authorities, such as new approaches, revised minimums, removed fixes, or updated airport data. Flying with an expired navigation database can limit GPS functionality and, in some cases, make certain IFR procedures unusable.
Why a BendixKing GPS Navigation Update Is Important
Keeping your BendixKing GPS navigation data current is essential for several reasons:
Regulatory compliance
For IFR flight, the FAA requires that navigation data used for GPS-based approaches and enroute navigation be current. An expired database may prevent legal use of RNAV procedures.
Navigation accuracy
Changes to airways, waypoints, and procedures occur frequently. Using outdated navigation data increases the risk of incorrect routing or missed procedure changes.
Flight safety
Accurate navigation data reduces pilot workload and helps prevent airspace violations, altitude errors, or approach mistakes—especially in complex or busy environments.
System functionality
Some BendixKing GPS units display warnings or restrict certain features when the navigation database is expired, which can be distracting or limiting during flight.
BendixKing GPS Systems That Require Navigation Updates
BendixKing offers several GPS and integrated avionics systems that rely on navigation databases, including models in the KLN and KMD series, as well as systems integrated into flight displays. Each unit may use a different database format and update method, making it essential to identify the exact model installed in your aircraft.
Some systems use removable data cards, while others rely on computer-based loaders or approved update tools. Installing the wrong database or using an incompatible update method can result in failed updates or system errors.
What You Need Before Updating Navigation Data
Before starting a BendixKing GPS navigation update, ensure you have the following:
- The exact BendixKing GPS model number
- An active navigation database subscription from an approved provider
- A compatible data card, USB device, or update loader
- A computer with internet access for downloading the update
- Stable aircraft power or an external power source
Reviewing the aircraft flight manual supplement or avionics manual is also recommended, as it may include model-specific update instructions.
How to Perform a BendixKing GPS Navigation Update
While the exact steps vary slightly by model, most BendixKing GPS navigation updates follow this general process:
- Check the current navigation database
Power on the GPS unit and access the database or system information page. Note the current AIRAC cycle and expiration date. - Download the correct navigation database
Log in to your database provider’s website and select the navigation update that matches your specific BendixKing GPS model. - Transfer the database to the data card or device
Use the provider’s software to load the navigation data onto the approved data card or transfer tool. Follow instructions carefully to avoid corruption. - Power off avionics before installation
Turn off the avionics master switch before inserting or removing data cards to protect the GPS unit. - Install the updated data card
Insert the card into the GPS unit securely, ensuring proper alignment. - Power on and initiate the update
Turn the avionics back on. Many BendixKing units automatically recognize the new navigation database, while others may prompt you to confirm installation. - Verify the update
After completion, return to the database information page to confirm the new AIRAC cycle and validity dates are displayed correctly.
Common Mistakes to Avoid
Several issues can occur during a BendixKing GPS navigation update if proper procedures are not followed:
- Loading a navigation database intended for a different GPS model
- Interrupting aircraft power during the update process
- Using damaged or outdated data cards
- Failing to verify the update after installation
Performing updates well before a scheduled flight helps ensure there is time to resolve any issues.
Best Practices for Navigation Database Management
Experienced pilots and operators often use a structured approach to manage navigation updates:
- Schedule updates at the beginning of each AIRAC cycle
- Keep spare or backup data cards if supported by the system
- Log navigation database updates in maintenance records
- Cross-check procedures with current charts after updating
- Conduct a brief ground check before flight
These practices help ensure consistent accuracy and reliability from your GPS system.
Conclusion
A BendixKing GPS navigation update is a small but essential task that plays a major role in flight safety, regulatory compliance, and operational confidence. By keeping your navigation database current, you ensure accurate routing, valid procedures, and dependable GPS performance. With proper preparation and a regular update routine, managing BendixKing GPS navigation updates becomes a straightforward and reliable part of responsible aircraft operation.
