Abstract�� Modeling and digital simulation are important phases in the development cycle of the civil flight management system. The distributed real-time simulation structure of the flight management system was proposed. The core function modules of the flight management system including flight planning, flight guidance, trajectory prediction, performance calculation, navigation, navigation database and display were modeled and the simulation algorithms were developed. Based on the avionics full-duplex switched ethernet (AFDX) protocol, the simulation module of the flight management computer, integrated navigation system and automatic flight control system were designed and integrated into the distributed system. A generalized AFDX-based distributed simulation system framework of the flight management system was presented. Simulation results demonstrate that the distributed AFDX-based framework can be implemented in real time applications with improvements on the performance of the network.
