Route Flight Assistant Decision System Key Issues

With the rapid development of civil aviation industry, there is a significant growth of air traffic flow and techniques improved incredible; The new navigation system has got general application, thus make it possible to fulfill free flight.The main content of this text is to solve pivotal problems of flight aid decision system of air route, offer decision help for air traffic control of air route and lighten the working load of control staff' s. This text has finished the job of the following several respect: set up kinematics and dynamics model to various kinds of state of flight separately, so to get necessary time of different flight course and position of random moment of future, according to the flight plan or control order; establish the judge model of flight conflict and conflict measures algorithm to help controllers to make decisions. Based on the judge model of flight conflict and conflict measures algorithm, use genetic algorithm to solve flight conflict.
