DYNAMIC SEPARATION MINIMA COUPLED WITH WAKE VORTEX PREDICTIONS IN DEPENDENT RUNWAY CONFIGURATIONS

摘要

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 im-plemetation 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.
