The development of modern aviation industry urgently needs a large number of high-level flight simulation device (FSD) for multiple applications such as technologies research, aircraft test and pilot training. Traditionally, these FSD are manufactured by different TDM to meet individual requirement, which may encounter difficulty in correctness, integrity or fidelity. How to develop the FSD and its simulation packages for research, engineering and training scenarios with a more coordinated and efficient methodology is the key to the development of high-level FSD for one particular aircraft project. This paper proposes that FSD shall be classified, according to development process and control requirements into three categories, which are Flight Simulation Training Device (FSTD), Flight Simulation Engineering Device (FSED) and Flight Simulation Research Device (FSRD). In particular, the simulation package provide the basis for the evolution of the multiple applications of the FSD. In this paper, the key design of FSD and simulation packages is given by proposing a technical strategy, which is based on system engineering (SE), with the development of FSED simulation packages as the central objective, and evolving and applying them to more mission such as research and training by validation and verification (V&V) of the requirement. This technical strategy shows major value (1) in optimizing correctness, integrity, and fidelity through process assurance, (2) in shortening the development cycle and reducing the cost by reducing duplication of efforts, (3) in reducing the technical risk of the simulation package, which is accompanied by aircraft and system design and development, and (4) in standardizing and eliminating of inconsistencies of the simulation modeling data, which is oriented from FSED with rigor configuration management. This research intends to promote the development of the domestic aircraft and the growth of the FSD-connected technology.
