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 Figure B-12. Note, in the following example, GRS1 is the first AHRS to
indicate an update is available. In actuality, this is dependent on which AHRS is the first to report status to the
system. GRS2 may be displayed before GRS1. The order is not important, only that both AHRS be updated.
