Hello! Sorry for the delay.
We have investigated this issue and concluded that something goes wrong in a module that Navigraph has provided in order to PMDG to support downloading navigation data from inside the aircraft.
While we have not been able to find out what exactly goes wrong, we are no longer able to reproduce the issue with the latest version of our module. We went from consistently seeing the issue to not seeing it at all!
We have sent an update to PMDG, so this should be included in a future update of the aircraft. In the meantime, you can actually install this yourself!
First - download this file:
msfs_navigation_data_interface.wasm (4.0 MB)
Then follow these steps:
- Find your Community folder
- Navigate to the following path (or equivalent for other variants):
Community\pmdg-aircraft-77f\SimObjects\Airplanes\PMDG 777F\attachments\pmdg\Function_Interior_77F\panel
- Replace the file in this directory with the one you downloaded
- Start the simulator
Please confirm if this fixes the issue for you as well!
Kind Regards,
Malte
