Claim 1
Independent Claim
157 words
An aircraft cursor controlled navigation system comprising: a navigation display for graphically displaying to the flight crew a sequence of waypoints defining a desired aircraft route and said navigation display also depicting a movable cursor; 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 menas including logic for allowing the flight crew to select a new or 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.
Claim 2
Dependent Claim
49 words
The aircraft cursor controlled navigation system of claim 1 wherein said logic means further includes: means for drawing a line between first and second selected waypoints on said navigation display and calculating and displaying the relative bearing and distance from said first selected waypoint to said second selected waypoint.
Claim 3
Dependent Claim
41 words
The aircraft cursor controlled navigation system of claim 1 wherein said logic means further includes logic for: determining if said cursor has been positioned within a predetermined position of a waypoint and, if so, highlighting said waypoint on said flight display.
Claim 4
Dependent Claim
30 words
The aircraft cursor controlled navigation system of claim 3 wherein said logic means further includes: means for producing a text display on said control display unit of said highlighted waypoint.
Claim 5
Dependent Claim
46 words
The aircraft cursor controlled navigation system of claim 4 wherein said logic means further includes: means permitting the flight crew to select said text display of said highlighted waypoint as a desired point on the route to thereby automatically enter said waypoint on the desired route.
Claim 6
Dependent Claim
49 words
The aircraft cursor controlled navigation system of any of claims 1 - 5, wherein: said manual input cursor control device comprises a touch pad; said logic means responds to relative movement of a user's finger across said touch pad to control movement of the cursor on said navigational display.
Claim 7
Dependent Claim
45 words
The aircraft cursor controlled navigation system of claim 6 wherein: said touch pad includes hot pad areas; and said logic means or said system responds to a user activating a hot pad area to move said cursor to a predetermined position on said navigational display.
Claim 8
Dependent Claim
44 words
The aircraft cursor controlled navigation system of claim 7 wherein: said manual input cursor control device comprises a selector switch; and said logic means responds to a user depressing said selector switch to select said highlighted waypoint as a waypoint on said desired route.
Claim 9
Dependent Claim
112 words
The aircraft cursor controlled navigation system of claim 1 wherein said logic means further includes: means for creating images of one or more predetermined control buttons on said navigation display responsive to the system's current mode of operation, and menas for performing the operation representated by said control button image in the event a user, through the manual input cursor control device, selects said control button; and means responsive to a user input to display on said navigation display a sequence of said control buttons, each control button corresponding to one of the possible waypoints within range of the display that the flight crew could select for inclusion on the desired route.
Claim 10
Dependent Claim
51 words
The aircraft cursor controlled navigation system of claim 9 wherein said logic means further includes: means responsive to two or more waypoints being too close on said navigation display to be designated for selection, to display a sequence of said control buttons, each control button corresponding to one of said waypoints.
