When loading into the simulator the aircraft may not hook in correctly. There are two methods of resolving this issue.
1) Run Fenix.exe as administrator before you launch MSFS and leave it running in the background. It will then sort itself out.
2) If you are already in the aircraft and the Fenix application is not open, do number 1 now.
3) If you are already in the aircraft and the Fenix application is open, close the Fenix application using task manager and restart the Fenix App as administrator.
