Previc, a human factors specialist who formerly led the Air Force's Spatial Disorientation Countermeasures Task Group, and Ercoline (disorientation countermeasures, the Air Force's School of Aerospace Medicine) collect information on spatial disorientation in flight. The book describes the movements of aircraft in mathematical detail, and explains how these movements can conspire to fool human sensory systems, especially the vestibular organs of the inner ear and the visual mechanisms that contribute to perceptions of motion. Chapters on countermeasures look at innovations in ground-based training, in-flight sorties, instrument training, and display design. Annotation ©2004 Book News, Inc., Portland, OR (booknews.com)
