Keeping Your Dynon SkyView Cockpit Calibrated and Maintained
Dynon SkyView systems have become a gold standard for modernizing single-engine piston aircraft, providing a rich, integrated flight experience. These glass cockpits combine primary flight displays (PFD), engine monitoring systems (EMS), navigation, and more into a seamless interface. While incredibly reliable, the precision of a SkyView system depends on proper maintenance and periodic calibration. For aircraft owners and pilots, understanding these processes is key to ensuring flight safety and getting the most out of their investment. This article will provide a comprehensive guide to the maintenance and calibration procedures for Dynon SkyView systems.
ROUTINE MAINTENANCE: A PROACTIVE APPROACH
The first rule of any aircraft system is that an ounce of prevention is worth a pound of cure. Routine maintenance for your Dynon SkyView begins with a simple, yet thorough, inspection. You or your certified mechanic should regularly check the physical components of the system for any signs of wear, damage, or loose connections. This includes the display units, the remote modules (such as the ADAHRS and EMS), the wiring harnesses, and the external sensors (like the pitot and static probes).
Visual inspection is critical. Look for any chafing on the wiring, especially where it passes through bulkheads or near sharp edges. Check for corrosion on the connectors and for any signs of moisture ingress. Ensure that all mounting hardware for the displays and remote modules is secure and that no components are vibrating excessively. Remember, these are sensitive electronic systems that can be affected by the harsh environment of an aircraft cockpit.
An important maintenance task is to regularly update the system’s software and aviation databases. Dynon provides these updates on its website. A mechanic can download the latest software to a USB drive and load it into the SkyView system. These updates often include performance enhancements, bug fixes, and new features. By keeping your system current, you ensure that you are operating with the most accurate and reliable software available.
THE IMPORTANCE OF CALIBRATION
Calibration is the process of fine-tuning the system to your specific aircraft. While the initial installation and calibration are performed by a mechanic, certain calibrations may need to be checked or adjusted over time. These procedures are essential for the accuracy of your flight and engine instruments.
One of the most important calibrations is for the air data sensors. The Dynon SkyView uses an Air Data, Attitude, and Heading Reference System (ADAHRS) module, which relies on pressure sensors for airspeed and altitude. The system requires a “zero pressure” calibration in a windless environment, such as a hangar. This procedure, performed with the pitot and static ports covered, ensures the system accurately measures pressure at zero airspeed.
Engine monitoring is another area where calibration is essential. The Engine Monitoring System (EMS) in a SkyView needs to be calibrated to the specific sensors and gauges in your aircraft. This is particularly true for fuel senders. A fuel tank calibration procedure, which involves incrementally adding fuel to an empty tank while recording the sensor values, is necessary to get accurate fuel quantity readings. A pilot who has seen the benefits of a properly calibrated fuel system will tell you it’s a huge confidence booster, especially on longer flights. It’s an example of the consistency principle at work; once you trust the data from your system, you are more likely to rely on it.
AUTOPILOT AND ADAHRS CALIBRATION
If your SkyView system includes an autopilot, the servos must be calibrated to ensure they operate correctly and safely. This involves a servo calibration wizard in the SkyView menu that identifies the orientation and range of motion for each servo. This process is followed by a servo test procedure. These are critical steps that must be performed by a qualified mechanic to ensure the autopilot’s performance and safety.
The ADAHRS module, which provides attitude and heading information, also has a calibration routine. The most common is the “in-flight” or “magnetic” calibration. This is performed by flying a series of coordinated turns in a specific pattern. It allows the system’s internal magnetometers to compensate for any magnetic interference from other aircraft systems, ensuring accurate heading information.
WHY PROFESSIONAL SUPPORT MATTERS
While some of these tasks might seem straightforward, a Dynon SkyView is a complex, integrated system. The FAA requires that all maintenance, including calibration procedures, be performed or supervised by a certified mechanic with an understanding of avionics systems.
As a certified aviation maintenance facility, we have seen numerous instances where a pilot’s attempt to “fix” or “calibrate” a system without proper training led to more significant problems. We’ve built our reputation on our expertise with these systems, and our customers’ continued trust in our services is a testament to our authority. Many pilots throughout California, Arizona, and Nevada rely on us for their maintenance needs, demonstrating the social proof of our quality work.
At The Aero Center, we have the specialized tools and training to properly diagnose and service Dynon SkyView systems. We understand that aircraft downtime is a major concern, and we pride ourselves on our efficiency.
