英文摘要：

The paper is aimed to improve the safety probability of the paired approach through accurate calculation of the size of the safety zone,which can help to avoid the aeroplanes interfere with each other as well as affected by the wake turbulence from the leading one.To achieve the purpose,we have developed the following model for the leading plane deceleration and that of the trailer for the paired approach.The actual process of the operation should be made to take place in the following order：First of all,in order to ensure the safety of the actual operation and control,it is necessary to take into full account both the human influential factors and the impact of the wake propagation features on the paired approach accomplishment.Secondly,it is also necessary to analyze the influential factors of the flying state of the two aeroplanes.Thirdly,we have brought about an improved calculation method that can help to identify and determine the minimum and maximum longitudinal division of the paired approach according to the following liability to the narrow-spaced parallel runways.Finally,we have accumulated and collected some ADS-B data from the Shanghai International Airport for simulations with the application of Matlab to simulate the model and the algorithm.At the same time,we have worked out the safe zone of the paired approach available for Shanghai Airport and analyzed the variations in the characteristic features of the safe zone by giving the sizes of the effective initial safe zone and the safe zone in view of the ground effect of the three home airports.The results of our simulated study suggest that the proposed algorithm proves to be effective in calculating the size of the safe zone.The analysis of the safe zone for the paired approach to Shanghai Airport let us find that at the beginning of the use of paired approach,the safe zone would be maximum.The size of the safe zone tends to decrease along with the process of approach going on until reaching the minimum size under the condition of the ground-eff
