近距平行跑道立体起降安全碰撞风险模型研究

针对进场复飞航空器与离场航空器之间的碰撞风险问题，通过分析由位置误差概率所产生的两机之间的真实距离和测量距离，评价两机之间的碰撞风险程度，从3个维度分析一起一降模式时的两机碰撞风险。结合复飞场景的不利环境因素，建立关于位置误差的三维碰撞风险模型。以此探讨近距平行跑道对起飞离场和进近降落航空器之间的安全间隔值的影响，具有重要的实际意义和理论意义。

Research on Safety Collision Risk Model of Three-dimensional Take-off and Landing of Short-distance Parallel Runway

Aiming at the problem of collision risk between approaching and departing aircraft, the real distance and measurement distance between the two aircraft generated by the probability of position error, is analyzed.The degree of collision risk between the two aircraft is evaluated, and the collision risk of the two aircraft in the one descent mode is analyzed from three dimensions.A three-dimensional collision risk model on position error is established in combination with the adverse environmental factors of the go-around scene. In this way, it is of great practical and theoretical significance to explore the influence of close parallel runways on the safety interval between take-off and departure and approach landing aircraft.
