Available in PDF, EPUB and Kindle. Book excerpt: The 1974 and 1975 aircraft accident experiences of civilian pilots with eight selected static physical defects have been examined and reported previously. Three categories--blindness or absence of either eye, deficient color vision with a waiver, and deficient distant vision--had significantly more accidents than were expected on the basis of observed-to-expected ratios. However, pilots with these conditions reported considerably higher median 6-month flight times than did an active airman population sample and accident airmen without selected pathology. In 1975 the reported recent and total flying times for all airmen with these defects were determined and accident rates were calculated. The rates for airmen with blindness or absence of an eye were still found to be significantly higher. The contact lens group was also selected to receive special attention in a study of the 1976 accident data because marginal significance was found on analysis of the 1975 data and, after 1976, this group will not carry a pathology code or require a waiver and thus will be difficult to study. Observed-to-expected ratios for 1976 are 1.91 for deficient color vision with a waiver, 1.28 for contact lens users, 1.37 for blindness or absence of either eye, and 1.62 for deficient distant vision. The accident rates per 100,000 hours of cumulative and last 6 months' flying experience were significantly greater for contact lens users and monocular pilots than for the active airman population.

Book excerpt: The medical records of airmen involved in midair collisions from 1970 through 1973 were reviewed and compared with two other groups of pilots: (1) pilots involved in other types of accidents and (2) pilots without any accident records. There is nothing in the results to indicate that the pilots with visual corrections are a greater risk.

Three categories--blindness or absence of either eye, deficient color vision with a waiver, and deficient distant vision--had significantly more accidents than were expected on the basis of observed-to-expected ratios. The 1975 accident data have now been examined. Again, the same three groups were found to have significantly more than their expected numbers of accidents. This year the reported recent and total flying times for all airmen with these defects were determined and accident rates were calculated. When the accident experience of airmen with any of these three static defects was compared with the active airman population accident experience per unit of recent and cumulative exposures, the rates for airmen with blindness or absence of an eye were still found to be significantly higher. Rates for airmen with color vision defects and a waiver were somewhat higher but of marginal significance. However, the rates for those with defective distant vision other than blindness or absence of an eye were similar and the difference was not significant. Only one of the FAA accident reports that were reviewed related the accident to the pilot's physical defect.

This book was released on 1983 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: In studies of the 1974-76 accident experience of U.S. general aviation pilots with static physical defects, all the significantly increased rates and ratios were for visual defect categories--blindness, or absence of either eye, deficient distant vision, deficient color vision with no operational limitations, and contact lenses. A 1979 study was limited to accident airmen with 19 visual deficiencies. The 1,140 pilots with aphakia and 173 with artificial lens implants had significantly higher rates, but the monocular pilots and contact lens users did not. The present study examined the 1980-81 accident experience of 4,169 monocular pilots, 1,299 with amblyopia, 969 with aphakia, 285 with lens implants, 118 with a history of diplopia, 1,269 with a tropia, 2,601 with hyperphoria>1 diopter, and 2,711 with esophoria or exophoria>6 diopters by class of medical certificate held. Numbers were too small for statistical treatment, but first and second class medical certificate holders, who often have more accidents per 1,000 airmen, consistently had progressively lower accident rates per 100,000 hours. They fly more. Monocular, aphakic, lens implant, and amblyopic accident airmen had higher accident rates than did the total airman population. Bases were found to question the value and adequacy of phoria and field of vision testing.

Download or read book New Refractive Surgery Procedures and Their Implications for Aviation Safety written by Van B. Nakagawara and published by . This book was released on 2006 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1980s, civil airmen have been allowed to correct refractive error (i.e., myopia, hyperopia, astigmatism) with corrective surgery. Prior Federal Aviation Administration research studies have shown that the number of civil airmen with refractive surgery continues to increase. A study that reviewed refractive surgery use in civil airmen for the years 1994-96, reported that the largest percentage had radial keratotomy (RK). A similar study that reported on the years 1996-2001, however, showed that there had been a substantial increase in the percentage of airmen with laser refractive surgery, i.e., photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK). A reference guide on refractive surgery was published in September of 1998 (DOT/FAA/AM-98/25); however, at that time long-term clinical data on PRK and LASIK were not available. The introduction of new refractive surgical techniques (e.g., laser epithelial keratomileusis [LASEK], laser thermal keratoplasty [LTK], conductive keratoplasty [CK], Intacs, phakic IOLs, and presbyopia surgeries) and technology (e.g., wavefront-guided systems, Femtosecond Lasers, inlays, and onlays) has further added to concerns regarding the use of refractive surgical procedures by aviators. In order to provide the aviation community with information to formulate administrative decisions and policies associated with existing and emerging refractive surgical procedures, this paper reviews current procedures and discusses their applicability in the civil aviation environment.

Download or read book Aviation Visual Perception written by Randy Gibb and published by Routledge. This book was released on 2016-04-15 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
