摘要
航路上航班的碰撞风险问题是目前空域规划的主要研究问题之一,就交叉航线的碰撞风险问题进行了研究。首先推导出交叉航路碰撞概率计算公式,然后结合概率论和划设保护区的方法对交叉航线的碰撞风险问题进行了研究,最后用自主开发的"空域安全评估方法的研究与应用"软件对上海区域内的某交叉航线的碰撞风险进行了仿真计算。为交叉航路的碰撞风险计算提供了简单易行的方法。
Collision risk between airplanes in routes is one primary question of airspace planning at present. Collision risk of crossing track is analyzed in this paper. Firstly, a formula for collision probability of crossing tracks is derived. Then collision risk of crossing tracks is analyzed by combining protected area methods with probability theory. Finally, the collision risk of crossing tracks in Shanghai area has been computed by “research and application on a method of airspace safety evaluation” which is software developed independently. The paper provides a feasible method for calculation of collision risk of crossing tracks.
