众所周知,机场的运营必须依靠严格的技术标准来保证航空器的飞行安全。随着地方经济的发展,在乌鲁木齐机场净空保护区域内需要建设很多民用建筑,确定这些民用建筑是否影响飞行安全,机场管理部门通常采用先勘测,再在航空专用地图上标绘和计算,这样做核准周期长,增加了建设的时间和成本,而且计算的准确度低,在一定程度上制约了地方经济的发展,同时也从侧面反映了我们在净空管理上的手段比较落后。一、概述如果我们把需要评测的建筑物视作潜在的障碍物,那么要确定障 As we all know, the operation of the airport must rely on strict technical standards to ensure the flight safety of the aircraft. With the development of local economy, many civilian buildings need to be built in the head-on protection zone of Urumqi Airport to determine whether these civil buildings affect the flight safety. Airport management departments usually use the first survey and then plot and calculate on the aeronautical special map. The long approval cycle has increased the time and cost of construction. Moreover, the low accuracy of calculation has restricted the development of local economy to a certain extent, and at the same time it reflects from the side that we are lagging behind in the means of headroom management. I. Overview If we consider the need to evaluate the building as a potential obstacle, then to determine the barrier
