LTITUDE ONSTRAINT
An altitude constraint is deleted by highlighting the altitude and pressing the CLR Key followed by the
ENT Key. In the event an altitude constraint is deleted and the navigation database contains an altitude
restriction for the lateral waypoint, the G900X displays the altitude restriction from the database provided
no predicted altitude can be provided.
Changing an altitude constraint:
1) Select the Active Flight Plan Page.
2) Highlight the desired altitude constraint.
3) Change the altitude constraint value.
4) Press the ENT Key to confirm the change.
Deleting an altitude constraint:
1) Select the Active Flight Plan Page.
2) Highlight the desired altitude constraint.
3) Select the CLR Key.
4) Select the ENT Key.
ALONG TRACK OFFSETS
An along track offset waypoint cannot be created if it is not adjacent to its parent waypoint
NOTE:
Offset distances can be entered from 1 to 99 nautical miles in increments of 1 nautical mile before the offset
waypoint (shown as a negative value) or after the offset waypoint (shown as a positive value).
A waypoint is allowed as long as the along track offset places the waypoint adjacent to its parent waypoint
in the lateral flight plan.
An along track offset that places a waypoint after the final approach fix of an approach is not allowed. Along
track offset waypoints lie along the great circle path of the existing lateral flight plan. Assigning an along track
offset to a leg with indeterminate length is not permitted.
Entering a negative offset distance results in an along track offset waypoint inserted before the selected
lateral waypoint, whereas entering a positive offset distance results in an along track offset waypoint inserted
after the selected lateral waypoint. The creation of multiple along track offset waypoints is allowed.
If the CLR Key is pressed prior to completing the definition of the along track offset waypoint, the
NOTE:
along track offset waypoint is removed.
An along track offset distance cannot be modified once entered. If the along track offset distance
NOTE:
must be changed, the existing along track offset waypoint must be deleted and a new one created with the
corrected offset distance.
