The first book to cover the entire spectrum of spatial disorientation in flight. This book examines the long history of spatial disorientation in flight, describes the movements of aircraft in mathematical detail, and explains how these movements can conspire to fool human sensory systems. It also examines the visual mechanisms that contribute to perceptions of self motion, describes the contribution of psychological factors to spatial disorientation and defines the types of visual and nonvisual illusions pilots experience in flight.

"Flying an aircraft is a challenging activity that exposes pilots to many potential hazards. One of the most significant of these is spatial disorientation. Spatial disorientation is a condition where the pilot is unable to correctly interpret aircraft attitude, altitude or airspeed in relation to the Earth. The resulting disorientation can lead to a loss of control of the aircraft. [...] The ATSB report explains that the chances of a spatial disorientation event occurring in flight can be reduced by a series of simple preventive measures, many of which can be attended to before flight. These include flying when fit and well to do so, not flying under the influence of alcohol or medications, avoiding visual flight rules into instrument meteorological conditions, increasing awareness of spatial disorientation illusions and planning for their possible appearance at different stages of flight in the pre-flight planning process."--Publisher's website.

A survey of 299 aircrew in current flying' practice was performed at five U.S. Army airfields within CONUS. Respondents were asked a number of questions about their worst ever episode of spatial disorientation (SD) and their worst episode in the 4 months prior to the survey. They also were asked to classify episodes as minor, significant, or severe according to the threat to flight safety. Opinions also were sought on various aircraft types and flight conditions. In the final part of the questionnaire, they were asked about their experience of break-off and giant hand phenomena. Analysis of the data showed that 78 percent had suffered SD during their flying career (8 percent had suffered severely enough to put flight safety at risk). Twenty-two percent had suffered in the 4 months prior to completing the questionnaire (2 percent severely enough to put flight safety at risk). In 33 percent of worst ever episodes, the event had affected conduct of the mission while flying accuracy had been affected in 64 percent. (The figures for the 4-month data were 35 percent and 68 percent.) Brownout, whiteout, and inadvertent entry to instrument meteorological conditions (IMC) were the most easily identifiable source of severe episodes of SD, but they accounted for 13 percent of the worst ever episodes. The leans accounted for 44 percent of episodes. Few other episodes could be linked to well known problems. Aircrew were not initially aware of being disoriented in 43 percent of worst ever episodes (38 percent of episodes when they were looking out of the aircraft cockpit). Experience had no apparent protective effect against either the incidence or severity of episodes.

Spatial disorientation (SD) refers to an incorrect self-appraisal of the attitude or motion of the pilot and his aircraft with respect to the earth. This paper defines elements of SD problems as encountered in general civil aviation. Accident reports made by the National Transportation Safety Board for a recent 6-year period were reviewed. Statistical computations were made relating SD to fatal accidents. Small fixed-wing aircraft (under 12,500 lb) accounted for 97.3 percent of all SD accidents. Inclement weather was associated with 42 percent of all fatal accidents, and SD was a cause or factor in 35.6 percent of these cases. Non-instrument-rated pilots were involved in 84.7 percent of SD weather-involved accidents. These and other data attest to the importance of this psychophysiological phenomenon (SD) in flight safety. Suggestions are made of ways to improve pilots' awareness and understanding of this problem.

"It has been known for many years that aircrew suffer from false sensations and perception of aircraft motion and these illusions may hazard the safety of the aircraft and its occupants. Yet, despite the many papers in the technical literature which deal with differing aspects of the problem of spatial disorientation there are few which are comprehensive and none provide the non-specialist reader with an explanation of the causes of the sensory illusions which reflect contemporary biological and medical knowledge. The text which follows was prepared in an attempt to redress this deficiency."--Preface.

Spatial disorientation (SD) is a long recognized problem in aviation environment. During flight the spatial disorientation may appear as a result of inadequate perception of the position or attitude of an aircraft in comparison of the co-ordinate system constituted by the Earth surface. It is extremely difficult to say how often spatial disorientation became the reason of military aircraft accidents 6 but in Poland it is calculated at around 8%. There is no ultimate cure for spatial disorientation; the two ways considered most important are pilot training and extensive research leading to better understanding of nature of SD which is little known despite of about forty years of worldwide awareness about this problem. Probably every air force in the world has its own methods for SD prevention and training programme. We think that most comprehensive approach to this question is introduction of wide training program using all available equipment and conducting of further experiments increasing our knowledge about this very complex problem. In 1998 PAFIAM went out with initiative of conducting the initial course and training counteracting spatial disorientation with polish military pilots using three simulators. The full mission flight simulator "Japetus" is the first element of this system of devices to work on spatial disorientation prevention. Another device is lately obtained Gyro - IPT spatial disorientation simulator, which's main purpose in contrary to "Japetus" is use in spatial orientation demonstration and training. Both previously mentioned devices are lacking of important possibility in terms of presentation of influence of linear acceleration on pilot's vestibular system. To make possibilities of presentation and training more comprehensive we decided to include human carrying centrifuge into spatial disorientation programme.

I am honored to have been invited to give the keynote address to this symposium on spatial disorientation. Spatial disorientation (S.D.) is not a new problem in aviation and over the last 50 years it has been addressed on numerous occasions within the NATO community. Yet despite the increased understanding of the varied aetiology of S.D. and improvement in the display of information to the pilot to facilitate correct spatial orientation (5.0.), accidents, primarily attributable to S.D., continue to occur. Indeed, in the last decade the proportion of human error accidents in which S.D. was considered to be a primary or contributory cause of the mishaps has increased. This would appear to be due, at least in part, to the introduction of new technology, in particular night vision goggles, that has allowed flight operations in environmental conditions which previously were not possible. In the presentations to follow there will be descriptions of new technologies and training techniques that should aid the maintenance of spatial orientation (8.0.) in flight and reduce the frequency of S.D. incidents and orientation error accidents. But these benefits are likely to be tempered by new challenges arising from flight in high performance agile aircraft and unattended aerial vehicles - UAVs. The human factors and aeromedical community also need to be cognizant of S.D. in virtual reality environments as well as in those piloting UAVs.
