A330-200 Nav question
I was wondering if anybody can tell me what the FCOM ref. is for the following issue that has been keepind me awake at night.

If GPS is deselected or not working what is the time limitation for IRS only navigation since last radio update?

6hrs springs to mind but I cant find the FCOM ref. to back this up.

Thanks in advance.
