Controlled Degradation of Resolution of High-Quality Flight Simulator Images for Training Effectiveness Evaluation

摘要

A flight simulator is a device used to train pilots and air crews without the use of an actual aircraft. The use of flight simulators for training is widespread in both the military and civilian sector. The use of flight simulators has significant advantages over the operation of the actual aircraft. In addition, pilots and air crews can practice complex and/or dangerous maneuvers in a flight simulator without risking loss of life or aircraft. As described by Schachter 6, sophisticated flight simulators recreate most of the aspects of flying: aircraft instruments, motion of the aircraft, gravitational forces, radar, and out-the-window views. Most modern flight simulators use computer generated imagery (CGI) to produce the out-the-window views in real-time in response to inputs from flight controls. The imagery can be displayed in a variety of ways: on large CRTs, projected onto the inside of a dome, or through helmet-mounted displays. Different training tasks are presumed to have different requirements with respect to brightness, contrast, and resolution. The goal for visual display flight training simulators in general, is not realism, but training effectiveness. Therefore, the design requirements for flight simulators should take into consideration the desired training task.(sdw)
