Book excerpt: When darkness falls, storms rage, fog settles, or lights fail, pilots are forced to make "instrument landings," relying on technology and training to guide them through typically the most dangerous part of any flight. In this original study, Erik M. Conway recounts one of the most important stories in aviation history: the evolution of aircraft landing aids that make landing safe and routine in almost all weather conditions. Discussing technologies such as the Loth leader-cable system, the American National Bureau of Standards system, and, its descendants, the Instrument Landing System, the MIT-Army-Sperry Gyroscope microwave blind landing system, and the MIT Radiation Lab's radar-based Ground Controlled Approach system, Conway interweaves technological change, training innovation, and pilots' experiences to examine the evolution of blind landing technologies. He shows how systems originally intended to produce routine, all-weather blind landings gradually developed into routine instrument-guided approaches. Even so, after two decades of development and experience, pilots still did not want to place the most critical phase of flight, the landing, entirely in technology's invisible hand. By the end of World War II, the very concept of landing blind therefore had disappeared from the trade literature, a victim of human limitations.

Available in PDF, EPUB and Kindle. Book excerpt: The distance at which an object becomes visible depends upon such factors as brightness contrast, target size, brightness level, and atmospheric attenuation. Numerical values are selected to represent the influence of these variables under the conditions of high altitude flight. Visibility is examined under the following conditions: (a) Altitude of observer--sea level, 50,000, 100,000, and 200,000 feet. (b) Altitude of target--from sea level to approximately 300,000 feet (60 miles). (c) Background brightness conditions--from 1 to 32 footlamberts. (d) Contrast ratio between target and background--for values of 1, 5, 10, and 100. The computation of visibility is based on visual acuity data corrected for the effect of atmospheric attenuation at various altitudes. A round object with a diameter of 10 feet may be used as a representative target. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Visibility matters in contemporary societies; online, in the media and in the public eye. But who is seen and how? Are women still seen through a male gaze? This book explores the politics of looking and being looked at, and the relationship between actual and virtual worlds, for example in sport, art and cinema.

Download or read book Comments on Air to Air Visibility at High Altitude written by and published by . This book was released on 1954 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aviators flying at high altitude report difficulty in sighting other aircraft. The factors causing this poor air-to air visibility are discussed, particularly the phenomenon of 'empty field' myopia. It is concluded that the correction of the myopia may moderately improve air-to-air vision. An experiment for quantitatively determining the improvement is proposed, and some practical methods of correcting the empty field myopia are suggested.
