Hi Eddie.....maybe a breakthrough here.
After several reintroductions of files, I have determined that Navigraph files are the problem.
First, AIRAC 2510r2 was updated and displaying correctly in the OIS, although the Default/Navigraph/AIRAC bar was flickering when that page opened.
Note with Navigraph files installed in CF, no VOR CDI, FREQ or DME on ND, or ILS freq/DME on PFD were showing - see 1st pic below
With Files (see pic 2 below) removed from CF - all normal - see 3rd pic below
Is Navigraph an issue with the A350? How is that fixed?
I'm also thinking that my issue MAY have been caused by updating Navigraph more than once. Could this create a problem?
SUGGESTION: In the 3rd Party tab in the OIS, could there be a comparison tab for AIRAC, comparing loaded version with latest available so we'd know whether to update Navigraph for instance
