航迹移动模型下的复飞航迹自动生成算法

Automatic generation algorithm of missed approach track based on track mobile model

随着现代计算机科技的发展以及地理信息技术的广泛应用,飞行程序设计人员可以直接利用数字方式获取使用机场空域内的障碍物位置和高程信息。飞行程序设计已逐步从手工设计阶段过渡到自动化实现阶段。飞行程序设计关注进离场程序、进近程序设计,其中进近程序的复飞航段是飞行过程中最重要的航段,其设计受障碍物分布、高度、导航台位置等诸多因素限制。基于DOC8168文件要求,结合传统复飞程序设计流程,对复飞程序的直线航段、转弯航段以及保护区的设计进行研究,明确了复飞程序设计的关键和难点在于复飞点、复飞爬升点和复飞转弯点的选择以及航迹航向和爬升梯度的确定。利用Arc GIS软件同时结合飞行程序设计流程,运用空间数据处理、编辑和空间分析组件,提出一种复飞航迹自动生成算法。该算法将最优复飞航迹、复飞程序保护区、风螺旋线、直线保护区与转弯保护区的衔接部分等绘制功能实现,且符合飞行程序设计规则要求,同时实现了飞行程序设计流程自动生成的需求。

：With the development of the modern computer technology and the widespread application of geographic information technology, flight procedure designers can directly get the information of obstacle location and height within aerodrome airspace in numeric mode. Flight procedure design has gradually transited from the manual design phase to automation phase. Flight procedure design focuses on arriving procedures, departing procedures and approach procedures, of which missed approach segment is the most critical segment of the flight process. Obstacle distribution, height and navigation station location and other limited factors have to be taken into consideration in missed approach segment design. Accord- ing to DOC8168 ,traditional missed approach procedure design process and the research on the straight, turning segment of the missed approach procedure and protection area design, it comes to a conclusion that the key points of missed approach procedure design are the selection of missed approach point, missed approach climbing point, missed approach turning point and the determination of the track head- ing and climbing gradient. Based on ArcGIS, flight procedure design process, spatial data processing andediting, spatial analysis components, an automatic generation algorithm of missed approach track has tion area and the turning protection area,which meets the requirements of flight procedure design rules and meets the need of flight procedure design automatic generation.
