Book Description
FOREWORD By Bruce McCandless II Former NASA Astronaut This volume is the fifth in the series on contemporary space topics by the Aerospace Technology Working Group with support from Secure World Foundation, the International Space University, and the International Institute of Space Commerce. It deals principally with the topic of sustainability of space operations. In all fields of challenging endeavor actually accomplishing an objective (e.g., putting a satellite into orbit) comes first, followed by exploitation or commercialization, and lastly by a realization that the resource is finite. Such "finite-ness" may come from considerations of pollution (e.g., space debris, propulsion effluent) or of actual limitations on the availability of the resource (e.g., crowding of Geostationary Earth Orbit - GEO). Both of these topics are among those discussed in detail in this volume. Developing countries, in particular, may find such considerations too burdensome, and this begs the need for regulation to avoid the classic "Tragedy of the Commons" situation. In the case of orbital debris we have collectively arrived at a point where tens of millions of tiny pieces of debris are currently in orbit, decaying at diverse rates in a situation where a single flake of paint has been demonstrated to be capable of causing damage when impacting at high relative velocities. At the other end of the spectrum, defunct satellites (e.g., ESA's Envisat) present discrete problems worthy of individual retrieval/disposal efforts but fraught with complications arising from ownership to potentially still effective ITAR constraints on access to onboard technology. And, of course, the managers of the International Space Station are absolutely paranoid about higher altitude orbital debris eventually decaying to and ultimately impacting their very large orbiting facility. While space may realistically be dubbed "infinite," very specific orbits, or sets of orbits, have practical capacity limits. In GEO, for example, spacing of satellites along it are subject to constraints arising from use of the same radio frequency spectra and the size of ground based antennas required to spatially discriminate between adjacent satellites. In popular high inclination sun-synchronous Earth imaging orbits, these all converge near the poles, creating a traffic management concern arising from the risk of collision. The subject of "green propellants" is treated from several aspects. The Liquid Oxygen / Liquid Hydrogen system, while yielding only water vapor from combustion, may have a significant carbon footprint associated with the manufacture of the LH2 from methane or methanol. Aluminum oxide, an exhaust product of common solid propellant boosters is generally regarded as inert, but the inhalation of fine particles of it can cause pulmonary fibrosis or other lung damage in humans. Additionally the need for oxidizer depletion shutdown in the family of hydrazine/oxidizer booster stages results in significant quantities of UDMH (for example) being dispersed upon impact of the early stages. No Foreword can do adequate justice to the carefully developed material within the publication itself. For a detailed and thought provoking coverage of the principal topics associated with the sustainability of space operations, this book is highly recommended, authoritative, and "a good read."

Book Description
Airlines are buffeted by fluctuating political and economic landscapes, ever-changing competition, technology developments, globalization, increasing deregulation and evolving customer requirements. As a consequence all sectors of the air transport industry are in a constant state of flux. The principle aim of this book is to review current trends in the airline industry and its related suppliers, thereby providing an insight into the forces that are changing its dynamics. The factors that are reshaping the structure of the industry are examined with a view to identifying the key issues whose impact will be critical in the future. The book features two very distinct sections. The first contains short contributions from industry executives at CEO/VP level from airlines, aircraft/engine manufacturers, safety and navigational provider organisations, who have set out their take of where the airline industry is heading. This commercial input sets the scene for the book and provides the bridge to the second section, which is composed of 18 chapters written by distinguished academic authors. Each chapter presents a valuable insight into a specific area of the air transport industry, including: airlines, airports, cargo, deregulation, the environment, navigation, strategy, information technology, security and tourism. The shared objective of the authors is to describe and explain the core competencies that are determining the current shape of the industry and to examine the forces that will change its direction going forward. The book is written in a management style and will appeal to all levels of personnel who work for airlines across the world. It is also written for airport authorities, aerospace manufacturers, regulatory and government transportation agencies, researchers and students of aviation management, transport studies, tourism and the wider air transport industry.

Book Description
Prepared at the request of NASA, Aeronautical Technologies for the Twenty-First Century presents steps to help prevent the erosion of U.S. dominance in the global aeronautics market. The book recommends the immediate expansion of research on advanced aircraft that travel at subsonic speeds and research on designs that will meet expected future demands for supersonic and short-haul aircraft, including helicopters, commuter aircraft, "tiltrotor," and other advanced vehicle designs. These recommendations are intended to address the needs of improved aircraft performance, greater capacity to handle passengers and cargo, lower cost and increased convenience of air travel, greater aircraft and air traffic management system safety, and reduced environmental impacts.

Book Description
Dr. Chun's Aerospace Power in the Twenty-First Century: A Basic Primer is a great start towards understanding the importance of aerospace power and its ability to conduct modern warfare. Aerospace power is continually changing because of new technology, threats, and air and space theories. However, many basic principles about aerospace power have stood the test of time and warfare. This book provides the reader with many of these time-tested ideas for consideration and reflection. Although Aerospace Power in the Twenty-First Century was written for future officers, individuals desiring a broad overview of aerospace power are invited to read, share, and discuss many of the ideas and thoughts presented here. Officers from other services will find that this introduction to air and space forces will give them a good grasp of aerospace power. More experienced aerospace leaders can use this book to revisit many of the issues that have affected air and space forces in the past and that might affect them in the future. Air Force officers will discover that Aerospace Power in the Twenty-First Century is a very timely and reflective resource for their professional libraries.

Book Description
The events of past years have shown how the threat of both intentional and natural disasters could bring the civil and the military worlds closer in the conceivement and deployment of countermeasures as well as in the identification of effective strategies for enhancing the Planet safety and security. In this frame, the concept of dual use - the set of technologies and applications that can be exploited for both civil and military purposes - becomes a key topic. In addition, the aerospace industry is a strategic building block in the deployment of a network centric environment that aims at the global protection of the mankind. Aerospace is a natural environment for dual use: many of the related enabling technologies have first been developed for the military world and then applied to civil - including commercial - purposes. On September 12-14, 2007 an International Symposium was held in Rome, joining the dual use approach with aerospace technology. The event called experts and operators from the military and civil community, belonging to industry, scientific, and governmental institutions. The common aim was an effective convergence between the available and perspected technologies for the civil and military worlds as well as the conceivement of applications that can take the maximum benefit from the dual approach, optimizing the available economic resources. The Symposium included invited-only contributions and an industrial panel. The main results of the Symposium, derived from key-note speeches, invited lectures, panel discussions, and conclusions, have created the starting material to develop this edited book. This book - the first on the topic - can be considered a milestone and a key-tool aimed at driving the industrial, scientific, and institutional efforts of the international community to guarantee a pleasant and safe future to the whole Planet.

Book Description
The effect that recent technological advances in aviation-related software, hardware, and infrastructure flying skills and their increased reliance on such devices during cloudless flights is examined in this authoritative Attitude Reference (VAR), the revolutionary flight training program, is at the center of this discussion and call for a visual flight instruction program similar to that of Basic Attitude Instruments (BAI). Core VAR segments, task prioritization, and proficiency segments for performance maneuvers--all of which lead efficiency and sound aeronautical decision--are discussed, as well as visual situational awareness and plane maintenance. Additional information is also provided on passing checkrides and oral examinations, pilot maintenance responsibilities, and FAA special-emphasis programs including the TAA Safety Study Standard.
