The STOL Maneuver Technology Demonstrator manned simulation test program

A description is given of the STOL (short takeoff and landing) Maneuver Technology Demonstrator (S/MTD) simulation, a high-fidelity pilot-in-the-loop motion base simulation. The simulation was used to evaluate takeoff, landing, and air-to-air tasks before first flight of the S/MTD aircraft to improve aircraft flying qualities, conduct engineering research, and insure safety of flight. 208 hours of pilot-in-the-loop evaluations were conducted. The authors describe the simulation hardware, test approach/results of the pilot vehicle interface (PVI), and flying qualities and aircraft failure evaluations in the STOL landing (SLAND) flight control system mode
