Wake-turbulence related separations are becoming an increasingly limiting factor to airport capacity. Furthermore the increasing traffic density predicted for the coming decades will very likely lead to an increased frequency of wake turbulence related incidents not only in the airport vicinity, but also in other flight phases such as during cruise. Maintaining or even improving safety with respect to wake vortex encounters requires new appropriate separation schemes to be developed, that take into account not only parameters of the wake vortices themselves, but also the effect of the wakes on the encountering aircraft. The validation of such separation schemes (as planned e.g. during the European ATM research undertaking SESAR) requires adequate simulation tools to demonstrate their safety. Airbus has developed such tools during several research projects and internal activities during the last years. These tools are based on a high-fidelity, dynamic aircraft wake encounter simulation called VESA (Vortex Encounter Severity Assessment) taking into account the interaction of the aircraft aerodynamics and flight dynamics with the vortices. Recent advances in the development of these tools, specifically during the recently finished EU research project CREDOS, will be presented. In this project the feasibility of an operational concept for reduction of departure separations under crosswind conditions was investigated. Airbus simulation tools together with new models for pilot behaviour, wake vortex simulation and severity assessment developed in the project were applied to perform a risk assessment regarding severe wake encounters during departure with reduced separations. The results that will be presented show the interactions between the wind conditions, the routing of the departing aircraft and their influence on the wake encounter risk.
