Waypoint Lock/Unlock
Locking a waypoint forces the user to consciously unlock the waypoint
before it can be modified and prevents the waypoint from being over-
written when waypoints are being input over the data port. Note that
when a waypoint received on the data port has the same waypoint
number as a locked waypoint already stored in the CDU, the waypoint
data received on the data port is disregarded and lost. Waypoints are
locked by one of three methods: 1) selecting
Lock this WPT
when in
the waypoint bank edit mode for a particular waypoint; 2) selecting
Lock this WPT
when in the waypoint bank edit mode; or 3) incorporat-
ing a waypoint into a route stored in
RTE2
and then locking the route.
Waypoints that are locked from the waypoint bank are indicated by a
closed padlock in the display. Waypoints that are party to a locked
route will display a message indicating that waypoint can not be modi-
fied.
To Lock a Waypoint
1. Select the
WPT
key until the
WPT1
screen is displayed.
2. Move the cursor to the desired waypoint.
3. Press the
E
key.
