ABSTRACT
However, due to geographical constraints, or the flight procedure design considerations, many closely spaced parallel runways is designed to be the threshold of the two runways staggered, We call this system of closely spaced parallel runways is close staggered spaced parallel runway[1]. Runways threshold staggered can be achieved in three ways: the runway threshold physical staggered; threshold displace; and combination of both. Research indicates that runway threshold have to stagger at least 300 m to significantly enhance closely runway capacity[2]. However, completely physical staggered will increase the amount of land use, and when the runway system uses the most common along with one arrival and one departure, with the running direction of the change, takeoff and landing
1 INTRODUCTION
At the beginning of the 1970s, the USA and Europe began to raise closely spaced parallel runways technology. At present, the rapid development of the civil aviation market which makes the construction of airports and other infrastructure needs a lot of land resources, but because of limited land resources, national efforts to control the basic construction land get more and more, making building large spaced parallel runway system economy and social costs unbearable. Therefore, there is a need in the finite field area within, to achieve the maximization of the runway capacity, improve the operational capability of the airport, only through the design different layouts runway system to achieve. In the country, in March 2008, Pudong Airport closed runway operation mode enabled, becoming China’s first implementation of the operating mode of the close-up runway airport. In March 2010, the Shanghai Hongqiao International Airport was officially opened a second runway, formed a group spacing of 365 meters with the original runway closely spaced parallel runways.
