I encountered this issue in my Microsoft Flight Simulator 2020. I’m using the PMDG 777, and the navigation data has been updated, but on all the ramps, there is no data displayed on the PFD or NAV, and I can’t use the ADIRU calibration. However, everything works fine if I start on the runway. Can anyone explain what might be the cause of this?

What do you mean "no data displayed"? Are the screens off? And what do you mean "I can't use the ADIRU calibration"? What happens if you push the button?

If you start on the ramp, is the aircraft in the cold and dark state? There is a time delay for the ADIRU to power up after selected 'ON', this will be several minutes if you have the realistic option selected in the settings.
