Message Comments
FPL WPT LOCK
– Flight plan waypoint

Upon power-up, the system detects that a stored flight plan waypoint is locked. This
occurs when an navigation database update eliminates an obsolete waypoint. The
flight plan cannot find the specified waypoint and flags this message. This can also
occur with user waypoints in a flight plan that is deleted.
Remove the waypoint from the flight plan if it no longer exists in any database,
Or
Update the waypoint name/identifier to reflect the new information.
