While completing checklist and checking the aircraft type and airac info on the mcdu, it is displaying NAV ACCUR DOWNGRADED constantly on all pages in the mcdu. Airac is updated through Navigraph Hub to the latest release. Not sure how i would have clicked something myself to make this happen, as this is the first time I have ever been in this aircraft....and I am only half done with the preliminary cockpit prep checklist.
