Flight Separation Research Based on the Aircraft Wake

Improving airspace and runway utilization is the key to reducing flight delays with the rapid development of the air transport industry. Current flight separation standards generally take excessive interval margin, resulting in unnecessary waste of airspace resources and runway resources. Wake accidents still happended even with strictly wake separation standards compliance, which is mainly due to the imperfect separation standards affected by the wake complexity and modeling imperfections. Refering to Chinese and international main wake models, we propose to improve the existing wake standard, usage of modern wake separation systems and dynamic wake detection strategy with automated judgment method. Purpose is reducing flight delays and improving the utilization of the airspace and runway on the basis of keeping safety.
