摘要

The implementation of aircraft wake reclassification control interval experiment is to reclassify different aircraft types according to different aircraft parameters and standards. On the premise of ensuring safety, it is of great significance to further reduce the safety interval between aircraft and enable the airspace to accommodate more aircraft to improve the safety and efficiency of civil aviation operation. Firstly, this paper introduces the operation of wake reclassification at home and abroad, and summarizes the basic theoretical research of aircraft wake reclassification. On the basis of relevant research, taking the aircraft type and time of landing in one day at Zhengzhou Xinzheng airport as the research object, and on the basis of relevant assumptions, the current standard, recat‐cn and recat‐eu average wake interval models are established. The model simulation results show that under the standard of recat‐cn that the wake interval of the same type is 2.5nmile (4.63km), the wake interval of Zhengzhou Xinzheng airport can be reduced by 21.17%; If recat‐eu standard is tried out, the wake interval of Zhengzhou Xinzheng airport can be reduced by 23.36%. The data show that recat not only improves the capacity of Xinzheng airport to a certain extent, but also improves the operation efficiency of the airport. At the same time, the sensitivity analysis method is used to study the front and rear approach combination of different aircraft in Xinzheng airport. It is concluded that recat has a certain stability for the airport runway capacity and efficiency, and has a positive significance for the airport runway capacity and operation efficiency.
