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.

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.

Now available in English for the first time, The Visibility of the Image explores the development of an influential aesthetic tradition through the work of six figures. Analysing their contribution to the progress of formal aesthetics, from its origins in Germany in the 1880s to semiotic interpretations in America a century later, the six chapters cover: Robert Zimmermann (1824-1898), the first to separate aesthetics and metaphysics and approach aesthetics along the lines of formal logic, providing a purely syntactic way of using signs, regardless of objective content; Alois Riegl (1858-1905), who went on to further develop aesthetics on the model of formal logic, creating a theory of style in response to Zimmermann's call for an aesthetics oriented toward formal logic; Heinrich Wölfflin (1864-1945), who represents a step toward an understanding of consciousness by using pictures as cognitive tools; Konrad Fiedler (1841-1895), the Saxon philosopher who considered the possibility that some kinds of images are made and viewed not for what they show, but for their visibility's sake alone; Maurice Merleau-Ponty (1908-1961), responsible for taking up the connections between the problems of reducing the range of potential meanings and contexts of a given image down to just the picture surface; Charles William Morris (1901-1979), who set out to establish whether a picture with no objective reference, such as an abstract painting, still counts as a sign, and if so, in what sense. Bringing these thinkers together and interlinking their ideas, Lambert Wiesing presents an engaging history of formal aesthetics, while reconstructing the philosophical foundations for the appearance of new image forms in the 20th century, including the video-clip, abstract collage, digital simulation and virtual reality. Using this original approach, The Visibility of the Image introduces the rise of modern image theory and provides a valuable account of our engagement with pictures in the 21st century.

Each time we see grim pictures of aircraft wreckage on a rain-drenched crash site, or scenes of tired holiday travelers stranded in snow-covered airports, we are reminded of the harsh impact that weather can have on the flying public. This book examines issues that affect the provision of national aviation weather services and related research and technology development efforts. It also discusses fragmentation of responsibilities and resources, which leads to a less-than-optimal use of available weather information and examines alternatives for responding to this situation. In particular, it develops an approach whereby the federal government could provide stronger leadership to improve cooperation and coordination among aviation weather providers and users.
