摘要
自由飞行是解决航路拥挤问题的一种有效方式,因此在自由飞行环境下对飞行碰撞风险进行研究显得尤为重要。提出了自由飞行环境下影响飞机定位误差的主要因素;以概率论为工具,建立了自由飞行环境下的碰撞风险评估模型;分别量化评估了各个主要因素对自由飞行环境下碰撞风险的实际影响度。得到的评估结果表明,碰撞风险模型能有效地对自由飞行环境下的碰撞风险进行评估,验证了模型的可行性。
Free flight is an effective way to solve the congestions of air traffic flow.Research on collision risk in free flight is very important.Firstly,in this paper the effect factors of aircraft positioning error are proposed in free flight.Secondly,by using the probability theory,the probability assessment model of collision risk is established.Finally,the effect value of three important factors on collision risk is computed respectively.The last assessed result shows that the model can evaluate the collision risk in free flight effectively,so the model is feasible.
