Conflict detection and resolved method based on speed regulation

With the rapid development of China"s civil aviation, the shortage of airspace resources and air traffic congestion is becoming more and more serious, and the resulting flight conflicts are also increasing. In this paper, a method for detecting and resolving flight conflicts based on speed regulation is proposed and the fuel consumption in the speed regulation maneuver phase is optimized by nonlinear programming. Determine the speed range in which the aircraft can be adjusted by means of flight conflict detection and resolved methods. Then, by optimizing fuel consumption during the speed adjustment maneuver phase, the most fuel-efficient speed in the adjustable speed range is obtained. Finally, the velocity profile is assigned to the relevant conflict detection and resolved method based on speed regulation in real time, so that the interval between the aircraft is greater than the given minimum safety interval. Through simulation analysis, the flight conflict detection and release method proposed in this paper can quickly resolve the flight conflict, and the method of nonlinear programming to optimize fuel consumption can bring greater fuel consumption savings, which is more meaningful.
