Magnetic Field Variation Database Update

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. 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.
