Automation and its attendant safety consequences are key foundations of the concept development. Historically, the division has developed products that have subsequently been implemented for the flying public, such as the Traffic Management Advisor, which is being deployed nationwide. For high-fidelity flight simulation, the division operates the world’s largest flight simulator (the Vertical Motion Simulator), a Level-D 747-400 simulator, and a panoramic air traffic control tower simulator. These simulators have been used for a variety of purposes including continued training for Space Shuttle pilots, development of future spacecraft handling qualities, helicopter control system testing, Joint Strike Fighter evaluations, and accident investigations. Personnel in the division have a variety of technical backgrounds, including guidance and control, flight mechanics, flight simulation, and computer science. Customers outside of NASA have included the FAA, DOD, DHS, DOT, NTSB, Lockheed Martin, and Boeing.
