a manual input cursor control device suited for receiving manual inputs to control the position of said cursor on said navigational display;
a control display unit including a keypad for allowing the typed entry of sequential waypoints to define a desired aircraft route and a text display of said typed entries; and
a logic means for directing aircraft flight in accordance with a flight crew input desired route, said logic means including logic for allowing the flight crew to select a new or revised desired route by manually selecting waypoints via the cursor control device with said newly selected waypoints automatically forming the desired route on both said navigation display and as a new or revised text display on said control display unit, said logic means including means for automatically deleting waypoints which are no longer on the desired route.

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).
