With the increasing system scale and complexity, safety analysis based on formal models has been widely used in the development of aircraft products. However, it’s quite difficult to build a complete, accurate and consistent safety model, especially for dynamic complex systems. To solve these problems, a practical safety modeling methodology based on Altarica, which contains three phases like information collection, model construction and model V&V, is proposed to establish a more structured, systematic and efficiency way in this paper. Detailed processes are declared for each phase. At last, a hydraulic system is taken as an example to show how to apply the safety modeling methodology in practical.
