November 7, 20241 yr 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.

Hello, Please ensure you have aligned your ADIRU switches on the overhead panel to the NAV position. Please also ensure you have cleared any potential discontinuities. Thank you EddieCommunity Manager iniBuilds Ltd. | inibuilds.com
March 2, 20251 yr You will get this message if the ADIRU is not on or is still aligning. Once you have put the switches in the NAV position you should see a message INS Align in X Minutes in the lefthand column on the upper central display. You can clear the message using the CLR button whilst the INS is aligning, and you will get messages stating that the accuracy has been upgraded once the timing message disappears
