Evaluation Of Capacity For Paired Operation On Closely-Spaced Parallel Runways

Due to the rapid development of the civil aviation industry,major airports in the world will soon face a state of gradual capacity saturation.Adjusting the runway operation mode and reducing the safety distance between aircraft are the main means to increase the airport’s security capacity.In this situation,the concept of paired operation on closely parallel runway was proposed.The problem of analyzing and evaluating the capacity of this operating mode also followed.The following work was carried out for this article.1.Considering the influence of pilot factors on the runway capacity of the paired operation mode.According to the types of human factors,combine the paired running interval criteria to construct a paired approach capacity analysis model under the influence of human factors,and then combine the paired approach capacity evaluation model and paired.Differences in the separation criteria for approach and paired departures were used to construct a capacity assessment model for the paired departure model.2.The concept of paired operating capacity range is proposed.The analysis of the wake motion characteristics and the degree of lateral migration of the wake are influenced by the ground effect and crosswind factors.Then,the paired approach and paired departure capacity models under the influence of crosswinds and the evaluation methods of crosswind limit conditions in the two paired modes were obtained.Comparing the different capacity ranges under different model combinations and the differences between the paired approach and the paired departure due to crosswind effects.3.According to the research method of single-runway mixed operation,combined with the operating characteristics of paired approach,paired departure and the influence of pilot factors,the method for assessing the time interval between the crosswind limitation conditions and the mixed operation aircraft of each model was obtained.Thus,a capacity analysis model for paired operation under four mixed operation modes is constructed.And compare the difference between the effect of each run mode on the increase in runway capacity.
