The document describes three facilities at NASA Ames Research Center called SimLabs that provide simulation capabilities for aerospace concepts and systems. The facilities are the Vertical Motion Simulator (VMS), FutureFlight Central (FFC), and Crew-Vehicle Systems Research Facility (CVSRF). They allow testing of concepts from initial development through integration and operation with realistic human-in-the-loop simulation. A range of aerospace research can be conducted including evaluation of complex systems, vehicle design, and air traffic concepts.
