Kurzfassung

The term simulator fidelity has become enormously important in the scope of simulation research, when as-sessing 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 engineering standard, by attacking the fidelity problem with comparison of simulator and the actual flight over some quantitative cues. Research flight simulation encompasses some differences from commercial flight simulation. It requires high flexibility and versatility concerning the cockpit layout and visual and motion systems, as well as flight simulation models. It shoud be easy to modify the flight simulation model or other soft- and hardware components of the simulator. By this, there is a need for an automatic test method, in order to determine the fidelity of the most relevant simulator subsystems, since they are often modified during the life cycle of the simulator. The Institute of Flight Systems (FT) at the German Aerospace Center (DLR) has a reconfigurable flight simulator, the Air Vehicle Simulator (AVES), for research of rotorcraft and fixed-wing aircraft. The study reported in this paper targets a model based testing approach designed to tackle the high flexibility requirement of AVES. This paper presents a metamodel for objective flight simulator evaluation. Metamodeling has been carried out in two levels. An Experimental Frame Ontology (EFO) has been developed adopting experimental frames from Discrete Event System Specification (DEVS), and as an upper ontology to specify a formal structure for simulation test. Then in Objective Fidelity Evaluation Ontology (OFEO) that builds upon EFO, domain specific meta-test definitions are captured.
