Removing an approach from a direct-to or active flight plan:
1) From the Flight Plan Window, press the MENU Key.
2) Highlight 'Remove Departure', 'Remove Arrival', or 'Remove Approach'
3) Press the ENT Key. A confirmation window appears listing the procedure that is about to be removed with 'OK'
highlighted.
4) Press the ENT Key.
Another Procedures Window option allows the pilot to select vectors to the final approach course.
Activating a (previously loaded) approach, with vectors to final:
1) Press the PROC Key to display the Procedures Window.
2) Highlight 'ACTIVATE VECTOR-TO-FINAL' and press the ENT Key.
In many cases, it may be easiest to "Load" the full approach while still some distance away, enroute to
the destination airport. Later, if vectored to final, use the steps above to select 'Activate Vector-To-Final'
— which makes the inbound course to the FAF waypoint active. Otherwise, activate the full approach using
the 'ACTIVATE APPROACH' option.
Activating a missed approach in the active flight plan:
1) Press the PROC Key.
2) Highlight 'ACTIVATE MISSED APPROACH'.
3) Press the ENT Key. A confirmation window will be displayed.
4) With 'ACTIVATE' highlighted, press the ENT Key.
