Miscellaneous Message Advisories

FPL WPT LOCK
– Flight plan waypoint
is locked.
Upon power-up, the G1000 system detects that a stored flight plan waypoint is
locked. This occurs when an aviation 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.
FPL WPT MOVE
– Flight plan
waypoint moved.
The system has detected that a waypoint coordinate has changed due to a new
aviation database update. Verify that stored flight plans contain correct waypoint
locations.
