Air traffic control
First Claim
1. An air traffic control system, for use by a controller controlling a plurality of aircraft, comprising:
- a processor,an input device,a display device,trajectory prediction means for calculating a predicted altitude trajectory for each of said plurality of aircraft, for inputting aircraft detected position data, and for recalculating said predicted altitude trajectory for each of said plurality of aircraft based on said position data,means for inputting and storing instruction data corresponding to level clearance instructions issued by said controller to one or more of said plurality of other aircraft, andmeans for causing a display on said display, said display comprising a graph indicating the predicted altitude trajectory for a selected aircraft of the plurality of aircraft, and indicating symbols, one for each of a plurality of other aircraft of the plurality of aircraft,said indicating symbols for each of the plurality of other aircraft indicating both the current level and the one or more levels for which said level clearance instructions have been input.

Abstract
An air traffic control system includes a trajectory prediction module for calculating a trajectory for each aircraft, for inputting aircraft detected position data, and for recalculating the trajectories based on said position data, and a conflict detector for detecting, based on the trajectories, future circumstances under which pairs of aircraft violate predetermined proximity tests, and for causing a display on the display device indicating said circumstances. The systems uses a first proximity test and a second, more restrictive, proximity test; and displays a symbol representing pairs of aircraft which violate the second test in a first mode, and those which violate the first set but not the second set in a second mode.

5. A method for operating a computerized air traffic control system, for use by a controller controlling a plurality of aircraft, comprising:
-
calculating a predicted altitude trajectory for each of said plurality of aircraft; receiving aircraft position data; recalculating said predicted altitude trajectory for each of said plurality of aircraft based on said position data; receiving and storing instruction data corresponding to level clearance instructions issued by said controller to one or more of said plurality of other aircraft; and displaying on a monitor a graph indicating the predicted altitude trajectory for a selected aircraft of the plurality of aircraft and indicating symbols, one for each of a plurality of other aircraft of the plurality of aircraft; wherein said indicating symbols for each of the plurality of other aircraft indicate both the current level and the levels for which said level clearance instructions have been input. - View Dependent Claims (6, 7, 8)
