在模拟研究的范围内，当评估训练效率和将训练转换为真实的飞行时，术语模拟器逼真度已变得非常重要。它被定义为飞行模拟器与真实的飞机特性相匹配的程度。模拟器客观逼真度是通过模拟器与实际飞行的比较，在一定的量化尺度上解决逼真度问题，提供了一个工程标准。研究飞行模拟器包括一些不同于商业飞行模拟器。他们需要高度的灵活性和多功能性有关的公鸡坑布局和视觉和运动系统，以及飞行模拟模型。应易于修改飞行模拟模型或模拟器的其他软件和硬件组件。为了支持这一点，需要一种灵活的自动化测试方法，以确定最相关的模拟器子系统的保真度，因为它们在模拟器的生命周期中经常被修改。该方法不仅应支持自动执行，而且还能自动生成测试用例，这些测试用例可能会发生变化，以及模拟器组件。德国航空航天中心（DLR）的飞行系统研究所（FT）拥有一个可重构的飞行模拟器，即飞行器模拟器（AVES），用于旋翼机和固定翼飞机的研究。本文采用基于模型的测试方法来解决AVES的高灵活性要求。本文的成果是一个基于模型的客观飞行模拟器评估的元模型。Meta建模分为两个层次。采用离散事件系统规范（DEVS）中的实验框架，建立了一个实验框架本体（EFO），并作为上层本体来描述仿真测试的形式化结构。然后在建立在EFO基础上的客观保真度评估本体（OFEO）中，捕获特定领域的元测试定义。
The term simulator fidelity has become enor- mously important in the scope of simulation research, when assessing training efficiency and the transfer of training to real flight. It is defined as the degree to which a flight simulator matches the characteristics of the real aircraft. Objective simulator fidelity provides an engineer- ing standard, by attacking the fidelity problem with com- parison of simulator and the actual flight over some quan- titative measures. Research flight simulators encompass some differences from commercial flight simulators. They require high flexibility and versatility concerning the cock- pit layout and visual and motion systems, as well as flight simulation models. It should be easy to modify the flight simulation model or other software and hardware compo- nents of the simulator. To support this, there is a need for a flexible automated test methodology, in order to deter- mine the fidelity of the most relevant simulator subsys- tems, since they are often modified during the life cycle of the simulator. This methodology not only shall support automated execution but also enable automated genera- tion of the test cases which are subject to change as well as simulator components. The Institute of Flight Systems (FT) at the German Aerospace Center (DLR) has a recon- figurable flight simulator, the Air Vehicle Simulator (AVES), for research of rotorcraft and fixed-wing aircraft. The study reported in this paper adopts a Model Based Testing approach to tackle the high flexibility requirement of AVES. The outcome of the paper is a metamodel for model-based objective flight simulator evaluation. Meta- modeling has been carried out in two levels. An Experi- mental Frame Ontology (EFO) has been developed adopt- ing experimental frames from Discrete Event System Speci- fication (DEVS), and as an upper ontology to specify a formal structure for a simulation test. Then in Objective Fidelity Evaluation Ontology (OFEO) that builds upon EFO, domain specific meta-test definitions are captured.
