Hi Captains,PMDG744: I just want to ask you if I did something wrong: On 28th of Jan 2006 I set up the CDU/ARAC with obviously old AIRAC-data(24.11. till 21.Dec. 2005)...http://forums.avsim.net/user_files/140327.jpgI'd expect the FMS to tell me that the NAV DATA is OUT OF DATE. What did I make wrong in the CAPTAIN'S FMCs Init&Verif.process?greets,Foizman

or more generally speaking: Is the function (NAV DATA OUT OF DATE)even available in the PMDG-744 FMS?

No, this is not featured. Most users do not update their nav database so it would be somewhat of a nuisance to them.
