Troubleshooting Non-functional Glass Cockpits in Aircraft

Your issue seems to be specifically related to aircraft with glass cockpits, which I've come across a few times during my journey with flight simulators. Before diving into possible solutions, a bit of clarity on your simulator version and any third-party add-ons would be helpful. However, I'll try to provide some generic troubleshooting steps based on the details you've given.

1. Graphics Drivers:
   First and foremost, always ensure your graphics drivers are up-to-date. Graphics drivers play a crucial role in rendering complex displays like those in glass cockpits. From my knowledge, both Microsoft Flight Simulator (2020) and X-Plane 12 rely heavily on modern graphics technologies. A quick visit to your GPU manufacturer's website should give you the latest drivers.

2. Simulator Settings:
   Dive into your simulator's settings. Some sims have specific options that influence the display quality and complexity of cockpit instruments. Reducing these might cause some elements, especially complex ones like glass displays, not to show correctly.

3. Check for Mod Conflicts:
   If you're using third-party aircraft or scenery, they might conflict with native or other third-party elements. It's worth disabling them temporarily to check if the problem persists.

4. Reinstall the Aircraft:
   Sometimes, the simplest solution can be the most effective. If the issue is restricted to a particular aircraft, consider reinstalling it.

5. Simulator Updates:
   Always ensure you're running the latest version of your flight simulator. Developers regularly release updates to address bugs and improve performance.

6. General Troubleshooting:
   Clear the simulator’s cache. Temporary files might sometimes get corrupted, causing unexpected behaviors.

7. External Resources:
   There are numerous online communities and knowledge bases dedicated to flight simulators. While I'd refrain from naming competing forums, a quick search with your problem specifics might yield fruitful results. Remember to be wary of downloading files from untrusted sources.

In case these solutions don't address your issue, please provide more specifics, such as the simulator version, any third-party add-ons, and your system specifications. With more details, I'll be in a better position to guide you further.

Happy flying!
