Entering Date
The navigation database contains two 28--day effective cycles.
Changing the active navigation database between the two cycles is
accomplished by pushing the 2R line select key.
When the FMS date corresponds to a day during one of the navigation
database cycles, that cycle is displayed in green. The remaining cycle
is displayed in amber. When both cycles are displayed in amber, either
the date is wrong or the navigation database has expired and must be
updated. The database cycle is only changed while on the ground.
When an active flight plan exists, the active flight plan is cleared when
changing database cycles.
The navigation database automatically sequences to the database
cycle at 0900Z. Depending on the location, the database cycle date
does not agree with the current local date.
