1 Abstract
Increasing system complexity and interdependence have driven Gulfstream to build real-time, pilot- and hardware-in-the-loop facilities for product development and production support. The Advanced Design Research Lab (ADRL) and Integration Test Facility (ITF) Labs, which support this function, are described.  At the core of the real-time simulations are Applied Dynamics International’s rtX and rtS computers running Simulink models and additional software developed at Gulfstream. Examples of how these facilities have successfully supported production and internal research projects are presented.

7 Conclusions
Simulation technology has provided a powerful tool for development of advanced programs at Gulfstream. By designing common models which can be used in all the facilities, the programs have moved from conception to flight testing more rapidly and with fewer errors during flight testing. The labs provide a safe environment for identifying and alleviating issues which could pose risks to air crews. The ability to quickly repeat test points to develop different techniques or to identify the cues to fly test points has proved to be important for crews and a valuable tool for communication (by demonstration) within the development team. The ability to fly highly unusual attitudes in the simulation also reduces the risks to the crew and aircraft while evaluating the expected behaviors of the systems. Lab testing is less expensive than airborne tests on the aircraft. By testing in the simulators engineers can evaluate a wide variety of test conditions more rapidly than can be accomplished in the actual aircraft. Having the ability to quickly change conditions, or quickly reset to a specific initial condition, maximizes the amount of testing that can be accomplished in a given period of time. The ability to run test scripts on the simulations has dramatically reduced the amount of time required to conduct tests. Advances in the simulation labs have provided engineers and pilots with greater capabilities than were available in the past and they will continue into the future.
