FPL WPT LOCK – Flight plan waypoint 
is locked. 
Upon power-up, the G1000 system detected that a stored flight plan waypoint 
was 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 flight plan user waypoints that are 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 way-
point 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.
TIMER EXPIRD – Timer has expired.
The system notifies the pilot that the timer has expired.
DB CHANGE – Database changed.  
Verify user modified procedures.
This occurs when a stored flight plan contains procedures that have been manually 
edited.   This alert is issued only after an aviation database update.  Verify that the 
user-modified procedures in stored flight plans are correct and up to date.
FPL TRUNC – Flight plan has been 
truncated.
This occurs when a newly installed aviation database eliminates an obsolete ap-
proach or arrival used by a stored flight plan.   The obsolete procedure is removed 
from the flight plan.  Update flight plan with current arrival or approach.
APPR VPROF – Approaching VNAV 
profile.
Aircraft is approaching VNAV profile.  Prepare to climb or descend to meet VNAV 
profile.

altitude.
