Safety risk assessment case study using Airspace Conflict Analysis Simulation

The concepts, operating paradigms, and required technologies of the Next Generation Air Transportation System (NextGen) are still evolving. These continuing changes highlight a need for a modeling platform that can effectively address the complexity of diverse future scenarios and help assess their impact on safety. We discuss this need in detail with respect to the requirements and benefits of such a flexible modeling platform. We describe the LMI ACAS (Airspace Conflict Analysis Simulation) tool, a simulation modeling framework with 3-dimensional visualization, and we show how such an application can meet these analytical requirements and discuss the benefits of implementing a multi-dimensional visualization.
