The Advanced Technologies Testing Aircraft System, ATTAS, is DLRs primary flight test vehicle to be used as a flying simulator to demonstrate and validate new methods and technologies. In order to provide broad testing capabilities ATTAS was heavily modified and equipped with a powerful digital fly-by-wirelight flight control system. Due to system complexity a piloted systems simulator of ATTAS was a critical element for fly-by-wire flight control development and functional validation as well as for aircraft operation. This paper will present a technical description of the simulator structure and simulation capabilities and will address the specific role of system identification techniques for simulator validation. Several examples will be given demonstrating the performance in system modelling and simulation fidelity by using these techniques. Finally, conclusions concerning the merits of systems simulation for the ATTAS development and operation will be discussed.
