Advanced Simulation in Undergraduate Pilot Training: Motion System Development

Abstract : The production of kinesthetic information pertinent to the aircraft piloting task by use of motion base devices relies on mathematical models which are developed in a largely empirical manner and evaluated in a subjective manner. The ASUPT simulator contains a motion math model which is developed in analytical fashion and permits broad latitude for experimenter input to alter or degrade the resultant motion information. This permits research that is useful in establishing a relationship between the amount and scope of motion information and training value. The motion system employed is a 60-inch six- degree-of-freedom synergistic system. It is driven in translation by a model which permits passage of acceleration onset information followed by controlled velocity and position washout. Rotational information is controlled by digitally implemented cue shapers, and sustained translation acceleration simulation is made available by subliminally tilting the motion system platform to cause a projection of the gravity vector to be aligned with the sustained force. This report discusses the implementation of these concepts, and forms a foundation for understanding the ASUPT motion system computer programs.
