plan is activated. When storing flight plans with an approach, departure or arrival, the GPS 400 will use the waypoint information from the
current database to define the waypoints. If the database is changed or updated, the GPS 400 will automatically update the information if the
procedure has not been modified. If an approach, departure or arrival procedure is no longer available, the flight plan will become locked until
the procedure is deleted from the flight plan or the correct database is installed. For information on loading an approach, departure or arrival,
see page 56. See page 47 for instructions on saving and copying flight plans.

expired database only after you have verified all route waypoints. Non-precision approaches may not be flown with an expired database. See
your approved Airplane Flight Manual Supplement for more information.

approach, departure or arrival waypoints is inserted into the flight plan—along with a header line
describing the instrument procedure you selected. The original en route portion of the flight
plan will remain active, unless you "activate" the instrument procedure; which may be done
when the procedure is loaded or at a later time.
Flight plans can also be stored with an approach, departure or arrival. Keep in mind that
the active flight plan is erased when the unit is turned off and overwritten when another flight
