Comment by VBprogrammer

I'm not sure presicely what you are ranting against. I mean it doesn't seem unlikely that an aircraft has a strict maintenance schedule right? You haven't even suggested that you don't think this is the case. You certainly haven't provided any sources suggesting that it isn't the case.

This isn't Wikipedia. We don't demand citations for every comment. From memory this isn't the first time an aircraft has suffered from similar issues where it needs to be restarted. It generally doesn't matter because they have to have their internal databases updated with changes to navaids, radio frequencies, airport closures etc.

Here is an example from a completely different aircraft from a different manufacturer:
