This occurs when the AIRAC cycle is outdated. There are 2 ways to fix this for the NGX. 1: Buy the latest AIRAC cycle for PMDG found HERE 2: If you don't wish to buy it but want to hide that message follow these instructions:

1. Navigate to FSX Root Folder\PMDG\NavData\
2. Backup the fmc_ident.txt (change name to fmc_ident.txt.bak)
3. Create a text file called fmc_ident.txt
4. Open the file fmc_ident.txt
5. Copy the following and paste into the fmc_ident.txt:

      	    [ident]	NavData=AIRAC-1108	OpProgram=AUG25DEC31/11	CoData=EAG-1108  

6. Save the file.

This second option will last till December 31st 2011. On January 1st 2012, the FMC message will reappear. When this time comes, PM me and I will create a new fmc_ident.txt for you to use.

Hi and thanks a lot for your help, have a good day in london, I'm in front of you on the other side of the channel, near St Valéry sur somme, best regards, benoît ( so sorry for my special bad english ! )

Wow, thanks a lot guy!I will consider that, because it is quite annoying...

Thank you, ma'am. I wish I had studied more in school, so I could know this kind of stuff.

Wait a minute.... when I was in school, there were no computers. So the problem isn't my intelligence, just my age.

+1 bumb as this one is quite useful for the annoying fmc message

Can somebody from PMDG tell us why they havent fixed this themselves? The options are either;1) buy it2) deal with it3) fix it UNOFFICALLY by a user. doesnt seem right.

There's nothing to "fix."

If the navdata is out of date on the real airplane you get a warning. That is what PMDG has simulated.

sure it is simulated as the real thing and I appreciate this but I do not want to buy new navdata cycles every month, an update 2 or 4 times a year is fine with me as long as the navdata base in fsx does not change anyway. so I will 'fix' this for me. would have been nice though to have a 'ignore navdata out of date' option in the FMC.

Did anyone choose option1 - to buy new navdata? What advantages does it have? Will it also include all terminal procedures?Nic

The navdata updates also include terminal procedures. The main advantage of updating is that you can download and use real-world charts and routes and expect the FMC to have the correct information. I don't normally update every 28 days, maybe 4-5 times a year.

So now the product is too real? HUH?

There will always be one complaining. Not realistic enough...too realistic.

I'm waiting for PMDG to fix the engines. They won't start unless the airplane is fueled. And, who wants to bother with that? Incomprehensible. Trevor
