Method and device for evaluating course changing path of aircraft in dangerous weather

Abstract

The invention relates to the technical field of air traffic control, in particular to a method and a device for evaluating a rerouting path of an aircraft in dangerous weather. The method mainly comprises the following steps: planning at least two navigation changing paths; calculating an economic evaluation index according to the fuel quantity; calculating a safety evaluation index according to a dangerous area passed by the route changing path; calculating a conflict evaluation index according to the number of flight conflicts between the aircraft and other aircrafts; calculating a coordination evaluation index according to the number of handover times of the control responsibility during flight; and according to one or more of the economic evaluation index, the safety evaluation index, the conflict evaluation index and the coordination evaluation index, performing weighted calculation on a comprehensive evaluation index of each retrofit path, and evaluating all retrofit paths according to the comprehensive evaluation indexes. According to the method, a comprehensive evaluation model can be constructed, the route changing path obtained by different algorithms under the same condition is evaluated, and an optimal path result under the same evaluation index is provided for a controller.
