新建或改、扩建民用机场的场道工程中,首先要解决的问题就是修多长的跑道。而这一问题是属于航务管理部门所做的“航行服务研究”中的一项内容。它需要根据机场净空、飞机性能、飞行的航线等诸多条件进行机场分析和航线分析而取得一个综合指标来确定。一般说来,飞机越大,航程越远,飞机的起飞重量越大,要求的跑道就越长;机场海拔越高,机场气温越高,要求的跑道也越长。因此,需要考虑以下六个方面来确定跑道长度。 1.机场的性质国际机场、干线机场和支线机场所需的跑道长度不同。国际机场需考虑世界上飞国际航线的大型飞机在其起降,例如需考虑波音747、麦道11、空中客车340;而
New or change, expansion of civil airport field project, the first problem to be solved is how long repair the runway. This issue belongs to one of the “Navigational Services Studies” done by the air traffic control authorities. It needs to be determined by a comprehensive index based on airport clearance, aircraft performance, flight routes and many other conditions for airport analysis and route analysis. In general, the larger the aircraft, the farther the voyage, the larger the aircraft takeoff weight, the longer the runway required; the higher the airport altitude, the higher the airport temperature, the longer the runway required. Therefore, the following six areas need to be considered to determine the runway length. 1. The nature of the airport The length of the runway required by international airports, mainline airports and regional airports varies. International airports need to consider that the world’s large aircraft flying international routes take off and land at their takeoff and landing point, for example, to consider Boeing 747, McDonnell Douglas 11 and Airbus 340; and
