An objective of this presentation is to walk the audience through some of the most sophisticated simulation and testing facilities in the world. We support a wide range of research, such as enhancement of aerospace systems and operations, human factors, accident investigations, studies aimed at improving aviation safety in the air and on the ground (airports), improving air traffic throughput rates at airports leading to automation of operations and processes at airports, integration of Unmanned Aircraft Systems (UAS) into the National Airspace System (NAS) and Urban Air Mobility (UAM) research. Our engineering modeling and test beds enable researchers to evaluate the benefits of new ideas at a system level as well as examine and refine individual concepts before following up with testing those concepts involving live aircraft, certification and FAA’s final approval. For larger-scale, human-in-the-loop experiments and simulations, we operate a suite of laboratories with additional capabilities to link the facilities and to utilize live-virtual-constructive (LVC) operations. These unique high-fidelity simulation facilities include the Vertical Motion Simulator (VMS) - the world’s largest flight simulator; Future Flight Central (FFC) - 360° visualization simulator; the Crew-Vehicle Systems Research Facility (CVSRF) – with more traditional hexapod simulators; the Distributed Simulation Research Lab (DSRL), and Air Traffic Control Simulation Laboratory.
