Altitude constraints can be modified or deleted after having been added to the flight plan. In the event
an altitude constraint is deleted and the navigation database contains an altitude restriction for the lateral
waypoint, the system displays the altitude restriction from the database provided no predicted altitude
can be provided. The system also provides a way to reinstate a published altitude constraint that has been
edited.
Removing an altitude constraint provided by the navigation database:
1) From Home, touch Flight Plan
2) Scroll the list, if necessary, and touch a VNAV ALT button to display the VNAV Altitude Window.
3) Touch the Remove VNAV ALT Button. A 'Remove VNAV altitude?' window is displayed.
4) Touch the OK Button. The altitude is now shown in white, indicating it is not usable for vertical guidance. To
cancel the request, touch the Cancel Button.
Removing an altitude constraint that has been manually entered:
1) From Home, touch Flight Plan
2) Scroll the list, if necessary, and touch a VNAV ALT button to display the VNAV Altitude Window.
3) Touch the Remove VNAV ALT Button. A 'Remove VNAV altitude?' window is displayed.
4) Touch the OK Button. The altitude is now shown in white, indicating it is not usable for vertical guidance. To
cancel the request, touch the Cancel Button.
Reverting a manually entered altitude constraint back to the navigation database value:
1) From Home, touch Flight Plan
2) Scroll the list, if necessary, and touch a VNAV ALT button to display the VNAV Altitude Window.
