SERVICE TIPS FOR DYNON SKYVIEW GLASS DISPLAY FAILURES
Dynon SkyView glass display failures in light piston aircraft require a systematic approach to troubleshooting and repair. The system is a highly integrated suite, and a display failure is often a symptom of a problem in a connected component, such as the power supply, wiring harness, or a remote sensor. The key to an efficient repair is a methodical diagnostic process that isolates the root cause before any hardware is replaced. This article outlines key service tips for addressing these issues.
TROUBLESHOOTING THE SKYVIEW SYSTEM
The first and most critical step is an accurate diagnosis. The Dynon SkyView system has built-in diagnostic tools that are essential for this process.
- Check System Logs: The SkyView display has an internal log that records fault codes, voltage fluctuations, and other events. Accessing this log is the most efficient way to begin troubleshooting, as it can often point directly to the failing component, such as a display unit (GDU), an Attitude and Heading Reference System (AHRS) module, or a magnetometer.
- Inspect Power and Wiring: Many display failures, including a blank or flickering screen, are power-related. Use a multimeter to check the voltage at the display unit’s power connections and at the main avionics bus. A consistent, stable voltage is crucial. A thorough physical inspection of the wiring harness for chafing, corrosion, or loose connections is also a critical step.
- Check Sensors: If a specific instrument, such as the airspeed indicator, shows a red “X,” it’s a sign of a sensor failure. The problem is likely in the pitot-static system or the remote sensor that feeds data to the display.
REPAIR AND MAINTENANCE BEST PRACTICES
Once the faulty component is identified, the repair process must be conducted with precision and in accordance with manufacturer guidelines. The principle of authority is paramount here; all work must be performed by a certified avionics technician who is trained and authorized to work on Dynon systems.
- Software Updates: The Dynon system relies on software, and a glitch can often be fixed with a simple software update. A new unit may require a specific software version to be compatible with other system components. Updating the software must be done using an approved laptop and software, following Dynon’s procedures precisely.
- Component Replacement: If a component needs to be replaced, it’s crucial to use a certified, factory-authorized part. The installation process is meticulous, requiring proper mounting, torqueing of screws, and connecting all wiring harnesses correctly as per the Dynon Installation Manual.
- Final Testing: After a repair, a thorough system check is non-negotiable. This includes ground checks to verify all flight instruments and engine monitors are working, and a functional flight test to confirm the system’s performance in the air.
