Abstract
An aircraft navigation control system includes a flight management system control display unit (12), a navigation display unit (40), logic circuitry (60) and a cursor control input device (70). The flight management system control display unit (12) includes a keyboard (30) to allow desired route waypoint modification via keyboard entries. These entries appear on a display (20) which provides a text listing of the selected waypoints. The navigation display (40) produces a graphical depiction of the selected waypoints as provided on the flight management system control display unit (12). In addition, the user may modify or create a new desired route by movement of a cursor (4) on the navigation display (40) to thereby highlight and select various waypoints as depicted on the display (40). By use of this graphical interface via a cursor control device (70) and the cursor (74) on the navigation display (40), a user may create, by a connect the dot approach, a new desired navigation route. Changes so entered on the navigation display (40) by the cursor control device (70) correspondingly create changes in the text display of the control display unit (12).
