Aviation Visual Perception


Book Description

Vision is the dominant sense used by pilots and visual misperception has been identified as the primary contributing factor in numerous aviation mishaps, resulting in hundreds of fatalities and major resource loss. Despite physiological limitations for sensing and perceiving their aviation environment, pilots can often make the required visual judgments with a high degree of accuracy and precision. At the same time, however, visual illusions and misjudgments have been cited as the probable cause of numerous aviation accidents, and in spite of technological and instructional efforts to remedy some of the problems associated with visual perception in aviation, mishaps of this type continue to occur. Clearly, understanding the role of visual perception in aviation is key to improving pilot performance and reducing aviation mishaps. This book is the first dedicated to the role of visual perception in aviation, and it provides a comprehensive, single-source document encompassing all aspects of aviation visual perception. Thus, this book includes the foundations of visual and vestibular sensation and perception; how visual perceptual abilities are assessed in pilots; the pilot's perspective of visual flying; a summary of human factors research on the visual guidance of flying; examples of specific visual and vestibular illusions and misperceptions; mishap analyses from military, commercial and general aviation; and, finally, how this knowledge is being used to better understand visual perception in aviation's next generation. Aviation Visual Perception: Research, Misperception and Mishaps is intended to be used for instruction in academia, as a resource for human factors researchers, design engineers, and for instruction and training in the pilot community.




Ground-referenced Visual Orientation in Flight Control Tasks


Book Description

Mounting interest and activity in the application of dynamic computer-generated imagery (CGI) analogous to a real-time contact view from an airplane call for renewed investigation of the essential visual cues for contact flight. CGI systems have application both as contact analog flight displays and as outside visual scenes for flight simulators. In either case, systematic errors in distance judgments are encountered with all optical and electronic imaging systems, thereby requiring compensation by magnifying their images. Results of an experimental investigation of biased distance judgments with a projection periscope account for, but do not explain, a portion of the systematic error. Explanation of the experimental findings requires the formulation and validation of a comprehensive theory of size-distance perception that will account for the host of unexplained experimental facts associated with judgments of the size and distance of objects in the visual field, including various optical illusions and the projection of after images.
