OBSOLETE WAYPOINT
Obsolete Waypoints are typically created when a multiply defined
database waypoint used on a stored flight plan is no longer found in
the database. This may happen when a new data-base is loaded. An
obsolete waypoint can be accessed only by verifying it as an existing
waypoint on a flight plan. It will be lost once it is erased from a stored
flight plan.
MESSAGES (MSG KEY)
System and Sensor mes-
sages are displayed on sepa-
rate pages in the Message
Section. They are accessed
by depressing the MSG Key.
The Message Section will
consist of as many pages as
are required to display cur-
rent messages. The MSG
Key is used to sequence
through the System and
Sensor Message Pages and
to return to the page that was
displayed before accessing
the Message Section.
NXT, BACK, and PRV keys
can be used to page forward
and backward through the
message pages.
System Messages describe
the system's operation with
all related aircraft systems
(Figure 2-89). Sensor
Messages describe the oper-
ational status of each naviga-
tion sensor (Figure 2-90).
In most instances when new messages are added, the Message light
will flash and a flashing yellow asterisk will appear adjacent to the new
message.
