Hi Swen, look here http://forum.avsim.net/topic/346431-navdata-out-of-date-fmc-fix/

Yes that is a solution for old data that i dont get this message. But i have installed the new one, the latest and get this error. This is first time, other navdata dont make trouble. FMC show up that its alright so what is the reason now that i get this message?

Other navdata don't make this trouble because they did not have a validity that includes crossing a year boundary.

I think the problem is that the FMC reads the end of the cicle in January but it know that it is december. It seems it doesn't take the change of the year in it's calculation and so it think the navdata is outdated.

Discussed at length in this topic:http://forum.avsim.net/topic/356547-navdata-out-of-date-with-latest-airac-1113/Obviously a trivial bug in the NGX, did anyone actually submit a ticket yet?
