Displays the effectivity date range for the active navigation database.
If the active navigation database is out of date, it can be changed to the inactive
navigation database. Pushing the date range prompt of the inactive navigation
database copies that date into the scratchpad. Pushing the date range prompt of the
active navigation database transfers the scratchpad date up to the ACTIVE
database line. The previous active date moves to the inactive date line.
The line title ACTIVE is above the active navigation database date. No line title
is above the inactive navigation database date. The navigation database date can
only be changed on the ground. Changing the navigation database removes all
previously entered route data.
When an active database expires in flight, the expired database is used until the
active date is changed after landing. The database expires at 0900Z on the last day
in the range.
