Characteristics of Flight Simulator Visual Systems
Abstract
Out-of-the-window visual simulation is a formidable challenge because of the fantastic performance capabilities of the human eye. It is, of course, totally impractical to set the requirements of a visual simulation system to match and performance of human eyes. Those who set requirements and determine specifications for simulator visual systems find themselves in a quandary. The technology is inadequate to provide the ideal system and our understanding of how a human uses the visual information in a simulator is insufficient to provide clear guidelines on how to make the necessary trade-offs. The continuing task, then, is to define the design characteristics that may affect perception of physiological responses, to establish the relative importance of the corresponding visual and physiological effects, and to understand their relationship with the physical continuums of the displays that can now be generated. This report addresses only a very small part of the total problem. The objective here was to identify and define those physical parameters of the flight simulator visual system that characterize the system and determine its fidelity. The desire was to establish the physical measures of image quality that are describable in objective terms. It is convenient to discuss the characteristics of visual simulation systems in terms of the three basic categories of spatial, energy, and temporal properties corresponding to the three fundamental quantities of length, mass, and time.
