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 overwritten 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) incorporating 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 modified.
