航路所谓空中航路,是指根据地面导航设施建立的供飞机作航线飞行用的、具有一定宽度的空域。该空域以连接各导航设施的直线为中心线,规定有上限和下限高度和宽度。民航航路是由民航主管当局批准建立的一条由导航系统划定的空域构成的空中通道,在这个通道上空中交通管理机构要提供必要的空中交通管制和航行情报服务。航路的宽度取决于飞机能保持按指定航迹飞行的准确度、飞机飞越导航设施的准确度等要素,还需要根据情况增加必要的缓冲区。因此空中航路的宽度不是固定不变 Air route The so-called air route, refers to the ground navigation facilities to establish for the aircraft for flight routes, with a certain width of the airspace. The airspace is centered on the straight line connecting the navigation aids and specifies the upper and lower height and width. The civil aviation route is an airspace consisting of airspace delineated by the navigation system, approved by the civil aviation authority, on which air traffic control agencies shall provide necessary air traffic control and navigation intelligence services. The width of the route depends on the aircraft can maintain the accuracy of flight by the specified track, the accuracy of the aircraft over the navigation facilities and other factors, but also need to increase the necessary buffer zone. Therefore, the width of the air route is not fixed
