Dynamic separation minima coupled with wake vortex predictions in dependent runway configurations

Abstract

Wake vortices are an issue affecting both capacity and safety of air traffic and therefore need to be dealt with by appropriate measures and procedures. Today, the only means to prevent wake vortex encounters is procedural separation which however is statical and in many cases conservative. The concept of dynamic separations using wake vortex predictions aims at optimising the separation between consecutive aircraft based on the knowledge of the actual position and strength of the wake vortices. A concept for approach procedures has been developed that involves dynamical calculation of minimum safe distance, adaption of follower aircraft speed and the corresponding approach types. The concept, its implementation and simulation test results will be presented and it will be discussed how it can be applied to contribute to an optimised use of available capacity while maintaining and improving the safety level.

Study on the influence of linear and nonlinear distribution of crosswind on the motion of aircraft wake vortex

“…One of the solutions for this problem is to manage the air traffic at the airport carefully. And several new methods [1][2][3] such as deep learning are proposed. However, a comprehensive study on the wake flow field is badly required, either by using a computational fluid dynamics (CFD) method or an experimental study based on the laser measured data.…”
