With spatial disorientation continuing to be a serious concern for flight safety and cockpit effectiveness, the Indian Air Force has called for information to procure three new spatial disorientation simulators for young pilots. The simulator is intended to be used for training of aircrew in recognizing and effectively managing the experience of disorientation providing demonstration of spatial disorientation, disorientation training in flight, flight simulation and night vision training and motion sickness desensitisation. The IAF wants the new simulators to help rookie pilots to build resistance the most common spatial illusions, including coriolis, somatogyral, oculogyral, graveyard spin, nystagmus, leans, autokinesis, false horizon and black hole approach. The IAF has stipulated that the trainer should preferably provide six-degrees of freedom, with three-degrees of freedom in roll, yaw the pitch axis. The system should include a dual cockpit with pilot seats adjustable. Interactive flight controls should include changeable re-centering forces and dampening, visual displays should include increased field of view (FOV) and infrared projection for Night Vision image. The simulator should include aircraft sound and vibration simulation, chin window to be available for landing on platforms like an oil rig.
