The existing problem in the modeling and development of aviation equipment simulation is analyzed, and the abstract modeling method of airborne aviation equipment is described in detail, which establishes simulation factory model and designs the abstract model of the three - layer simulation system of the factory - aircraft - airborne equipment. Task description of the equipment simulation method is applied in the three-tier simulation system within a very good expansion function. Based on simulation factory model, the architecture of simulation training platform is constructed, and SLC-DLC aviation equipment modeling method is proposed, the development process and model interactive method are given based on the customized SDK. The platform realizes the unified modeling of the aviation equipment. Rapid production of new methods reduces the difficulty of large-scale aviation equipment simulation development, and solves the problem of airborne equipment simulation inheritance and achieves a high degree of reconstruction of airborne equipment. Experimental results show that the proposed method could be used for both development and development of simulators and multi-model tactical simulation systems.
