Graphic closure indicator for cockpit traffic display
First Claim
1. A system for displaying aeronautical information, said system comprising:
- a central processing unit;
a memory coupled to said processing unit; and
a display screen coupled to said central processing unit, said central processing unit being configured for executing the steps of;
determining whether a target aircraft is within a pre-determined monitoring zone; and
responsive, at least in part, to said target aircraft being within said pre-determined monitoring zone, displaying a closure indicator on said display screen.

Abstract
A system for graphically displaying on a cockpit display an indication of closure (i.e. a “closure indictor”) with a selected target aircraft. In a preferred embodiment of the invention, the system only displays a closure indicator if: (1) the selected target aircraft is within a predetermined monitoring zone; and (2) the track of the selected target aircraft is within a pre-determined variation angle of the track of the Own Ship aircraft. If the rate of closure between the selected target aircraft and the Own Ship aircraft is within a predetermined range of values, the closure indicator includes a closing/receding indicia (such as an upwardly or downwardly directed arrow) that indicates whether the Own Ship aircraft is closing in on or receding from the selected target aircraft. The system preferably removes the closure indicator from display when the Own Ship aircraft or the selected target aircraft ceases to be airborne.

41. A computer-readable medium comprising computer-executable instructions for performing the steps of:
-
comparing a track of a target aircraft with a track of an Own Ship aircraft; and
responsive, at least in part, to said track of said target aircraft being within a pre-determined variation angle of said track of said Own Ship aircraft, displaying a closure indicator on said display screen. - View Dependent Claims (42, 43)

44. A method of displaying aeronautical information, said method comprising the steps of:
-
determining whether a closure rate between a target aircraft and an Own Ship aircraft is above a predetermined upper threshold value; and
responsive, at least in part, to said closure rate being above said predetermined upper threshold value, performing a step of displaying a closure indicator on a display screen, said closure indicator comprising a closing/receding indicia. - View Dependent Claims (45, 46, 47, 48, 49)

50. A system for displaying aeronautical information, said system being configured for use within an Own Ship aircraft, and said system comprising:
-
a central processing unit;
a memory coupled to said processing unit; and
a display screen coupled to said central processing unit, said central processing unit being configured for executing the steps of;
determining a closure rate between a target aircraft and said Own Ship aircraft;
displaying a symbol representing said Own Ship aircraft on said display screen; and
displaying a closure indicator on said display screen adjacent to said symbol representing said Own Ship aircraft, said closure indicator being operative to visually relate said closure rate to a user. - View Dependent Claims (51, 52, 53)
