Upon initiating the recent procurement of a new OFT for a Navy tactical aircraft, NTSC was faced with a design problem: how to position the wide field-of-view day visual system in order to provide effective training for ground-referenced aircraft operations (takeoff, landing, enroute navigation, maneuvering flight, spin recovery) and also provide training in air refueling. The trainer's manufacturer developed a unique solution: install the trainee station cockpit on a separate buffet platform capable of operation at two different pitch attitudes, and mount the buffet platform on the motion base along with, but separate from, the visual system. Using this design, most flight training activities are conducted with both the motion base and the buffet platform oriented horizontally. For air refueling training, the buffet platform is pitched 10 degrees nose down while the motion base is pitched 10 degrees nose up, thereby repositioning the visual field-of-view along the cockpit centerline 10 degrees upward. Not only does this arrangement provide effective field-of-view coverage for all training tasks, but it substantially reduces the vibrational stress on the display components of the visual system by isolating them from the high-frequency vibration and buffet cues which are now applied only to the cockpit.
