The steady increase in air traffic imposes a need for enhanced airport capacity, and the desire to safely reduce existing separation minima. An important limiting factor in establishing required separation minima is wake vortex induced risk. A novel probabilistic methodology is under development for the assessment of wake vortex induced accident risk. The methodology is integrated within a stochastic framework. Three probabilistic sub models are being used: Wake vortex evolution model; Wake encounter model; Flight path evolution model. This probabilistic methodology can be used for an assessment of wake vortex safety of different Air Traffic Management (ATM) concepts or procedures. It provides a tool to evaluate separation distances for the current practice, and for promising new ATM concepts which may enable a safe reduction of current separation minima. Numerical results can be fed back to ATM designers, who can use these results to redesign or improve their proposed ATM concept. This paper outlines the probabilistic methodology, and illustrates its initial application for the single runway approach under current flight regulations.
