The invention belongs to the technical field of air traffic management, and particularly discloses a parallel runway hybrid approach operation rapid conflict risk calculation method based on TCAS, comprising the steps of establishing an aircraft motion model, including projecting an aircraft motion trajectory to a runway system plane, and establishing horizontal and vertical motion models of two aircrafts; a flight path error model is established, flight path deviation data fitting is adopted to obtain the relation of the normal standard deviation changing along the flight path, and the flight path change of the airplane is corrected to obtain the real position of the airplane; establishing an aircraft conflict detection model, including obtaining the relative distance and the relative speed of the aircraft in the horizontal direction and the vertical direction, and calculating the predicted meeting time of the aircraft at each moment; when the flight path of the invading aircraft is predicted to penetrate through the collision area, the system notifies the flight crew with visual and auditory signals. According to the method, factors such as a simultaneous approaching flight program and navigation parameters are verified in a planning stage, and the parallel runway operation conflict risk can be quantitatively evaluated more objectively.

    本发明属于空中交通管理技术领域,具体公开了一种基于TCAS的平行跑道混合进近运行快速冲突风险计算方法,包括建立飞机运动模型,包括将飞机运动轨迹投影至跑道系统平面,建立两架飞机的水平方向和垂直方向运动模型;建立航迹误差模型,采用航迹偏差数据拟合得出正态标准差沿航迹变化的关系,并对飞机航迹变化进行修正得到飞机真实位置;建立飞机冲突探测模型,包括得到飞机在水平方向和垂直方向的相对距离和相对速度,并计算得到飞机在每时刻预计相遇时间;当预计入侵飞机的飞行轨迹会穿透碰撞区域,系统用视觉和听觉信号通知机组人员。本方法实现在规划阶段对同时进近飞行程序、航行参数等因素的验证,能够实现更加客观地对平行跑道运行冲突风险定量评估。
