Loading the magnetic field variation database update:
A copy of the current magnetic field variation database (MV DB) is included with
the navigation database. At startup, the system compares this version of the MV
DB with that presently being used by each AHRS (GRS1 and GRS2). If the system
determines the MV DB needs to be updated, a prompt is displayed on the Navigation
Map Page, as shown in the following figure.
