A method is presented that allows a model-based development of a fault diagnosis system for an aircraft hydraulic power distribution system. For this, a steady-state model that contains nominal and faulty behaviours is modelled with the software Rodon. On the basis of the model, the sensibility of system states to faults is analysed and conclusions are drawn considering the optimal placement of sensors. In addition, diagnosis rules are derived.
