摘要
针对升降带宽度缩减给机场净空管理带来的新问题,将升降带缩减前后对过渡面的设置及限高情况进行对比分析。以跑道中点为原点建立直角坐标系,对跑道纵坡为0的情况下标准形式过渡面各关键位置点的设置参数进行计算,并提出运用过渡面进行障碍物限高评价的公式。实例分析中,依据跑道中线各点的标高变化情况,绘制某机场过渡面,并对5个障碍物的超高情况进行对比,阐述升降带缩减后给过渡面内障碍物限高计算工作产生的影响。
In view of the new problems brought by the reduction of the strip to the airport clearance management,this paper makes a comparative analysis of the setting and the obstacle height limitation of the transition surface before and after the reduction of the strip.Taking the middle point of the runway as the origin,a rectangular coordinate system is established to calculate the setting parameters of the key points of the standard transitional surface when the longitudinal slope of the runway is 0.In addition,it puts forward a formula for evaluating the limited height of obstacles by using the transition surface.In case analysis,according to the elevation change of each point in the runway center line,the transition surface of runway is drawn.In order to explain the influence of the reduction on the calculation of limited height of obstacles in transitional surface,5 obstacles are assumed to calculate the allowable height of obstacles.
