Training Design in Aviation (Paperback): Norman MacLeod Training Design in Aviation (Paperback)
Norman MacLeod
R1,570 Discovery Miles 15 700 Ships in 10 - 15 working days

Well structured training, based on sound theoretical principles, can transform the system in which high performance is essential and in turn, the organisation. Yet the strategic role of cost-effective training provision is often less well understood than it might be in all branches of aviation - whether civil or regional, general, business or military. This book analyzes the cycle of training design from the identification of requirement through to measurement of effectiveness. Key issues in training design and management are illustrated with examples and learning is consolidated through case studies. The book provides advice, tools, procedures and examples of best practice - both recent and well-established - to assist aviation training personnel who aim to guarantee cost-effective training. The approach is highly practical, but does not avoid covering the theory when needed. An informative guide to the process of training analysis and course design, the book examines each stage of the training design cycle in some depth. In addition, it looks at the application of quality management and of project management to training design. Each chapter contains advice and techniques, as well as examples drawn from the author's wealth of experience of training in aviation.

Air Power in the Maritime Environment - The World Wars (Hardcover, New Ed): David Gates, Ben Jones Air Power in the Maritime Environment - The World Wars (Hardcover, New Ed)
David Gates, Ben Jones
R4,784 Discovery Miles 47 840 Ships in 10 - 15 working days

This book explores the mingling of two rather different perspectives, those of the naval and aeronautical schools of thought, and the impact that they had upon one another in natural, professional and geopolitical settings. To explain the manner in which air power was incorporated into warfare between 1914 and 1945 it studies the deeds of practitioners, the limitations of technology, the realities of combat and the varying institutional dynamics and strategic priorities of the major maritime powers. It is underpinned by an appreciation of the geostrategic setting of the key maritime states, while addressing the challenges of operating in this multifaceted environment and the major technological developments which enabled air power to play an ever greater role in the maritime sphere. The potential for air power to influence warfare in the maritime environment was fully realised during the Second World War and its impact is demonstrated through an analysis of a wide range of the fleet operations and how it was utilised in the defence of trade and sea lanes. As such this book will be of interest to both naval and air power historians and those wanting a fuller perspective on maritime strategy in this period.

Civil Aviation and the Globalization of the Cold War (Hardcover, 1st ed. 2020): Peter Svik Civil Aviation and the Globalization of the Cold War (Hardcover, 1st ed. 2020)
Peter Svik
R3,334 Discovery Miles 33 340 Ships in 18 - 22 working days

This book focuses on the highly complex and intertwined relationship between civil aviation, technological globalization and Cold War politics. It explores how the advancement of Soviet civil aircraft engineering during the 1950s technically triggered the globalization of the Cold War. The study also shows how the processes of technological standardization facilitated transfers of technology and knowledge across the Iron Curtain and how East-West as well as East-South connections evolved. It uncovers the motives and reasons for this transfer of knowledge and expertise, and aims to identify the specific roles played by states, international organizations and interpersonal networks. By taking a global approach to this history, the book advances ongoing debates in the field. It reassesses Europe's role in the Cold War, pointing out the substantial differences in how Western Europe and the United States viewed the Communist world. This book will be of interest to scholars of international history, the history of technology and Cold War history.

Airspace Closure and Civil Aviation - A Strategic Resource for Airline Managers (Hardcover, New Ed): Steven D. Jaffe Airspace Closure and Civil Aviation - A Strategic Resource for Airline Managers (Hardcover, New Ed)
Steven D. Jaffe
R4,507 Discovery Miles 45 070 Ships in 10 - 15 working days

The impact to airlines from airspace closure can be as benign as a two minute extension on an arrival pattern, or as catastrophic as a shoot down from a surface-to-air missile, as the tragic loss of Malaysia Airlines Flight 17 over the Ukraine in July 2014 demonstrates. Airspace constraints come in a variety of forms, both man-made and physical, but all result in operational inefficiencies that erode the economic vitality of an airline. Understanding the root causes of these airspace restrictions, developing strategies for mitigating their impact, and anticipating future airspace closures, are critical for the efficient and safe operation of any airline. This book uniquely examines the technological, geographic, regulatory, and political aspects of airspace closure, with a focus on how airlines continue to adapt to overcome these challenges, providing readers with a framework for identifying issues and solutions in a systematic manner. Filled with historical references and contemporary anecdotes, this book serves both as a practical guide and strategic resource for airline managers navigating their 21st century. organizations around some of the lingering 20th century obstacles.

Synthesis of Subsonic Airplane Design - An introduction to the preliminary design of subsonic general aviation and transport aircraft, with emphasis on layout, aerodynamic design, propulsion and performance (Hardcover, 1982 ed.)
E. Torenbeek
R2,258 Discovery Miles 22 580 Ships in 10 - 15 working days

Since the education of aeronautical engineers at Delft University of Technology started in 1940 under tae inspiring leadership of Professor H.J. van der Maas, much emphasis has been placed on the design of aircraft as part of the student's curriculum. Not only is aircraft design an optional subject for thesis work, but every aeronautical student has to carry out a preliminary airplane design in the course of his study. The main purpose of this preliminary design work is to enable the student to synthesize the knowledge ob tained separately in courses on aerodynamics, aircraft performances, stability and con trol, aircraft structures, etc. The student's exercises in preliminary design have been directed through the years by a number of staff members of the Department of Aerospace Engineering in Delft. The author of this book, Mr. E. Torenbeek, has made a large contribution to this part of the study programme for many years. Not only has he acquired vast experience in teaching airplane design at university level, but he has also been deeply involved in design-oriented re search, e.g. developing rational design methods and systematizing design information. I am very pleased that this wealth of experience, methods and data is now presented in this book."

High G Flight - Physiological Effects and Countermeasures (Hardcover, New Ed): David Newman High G Flight - Physiological Effects and Countermeasures (Hardcover, New Ed)
David Newman
R3,372 Discovery Miles 33 720 Ships in 10 - 15 working days

This book provides a unique, authoritative and detailed examination of the physiological and clinical consequences of human exposure to high G forces. Pilots of military fast jets, civilian aerobatic pilots and astronauts during the launch and re-entry phases of spaceflight are frequently and repetitively exposed to high G forces, for which the human body is not fundamentally designed. The book examines not only the nature of the high G environment, but the physiological effects of exposure to high G on the various systems of the human body. In particular, the susceptibility of the human cardiovascular system to high G is considered in detail, since G-Induced Loss of Consciousness (G-LOC) is a serious hazard for high G pilots. Additionally, the factors that influence tolerance to G and the emerging scientific evidence of physiological adaptation to high G are examined, as are the various countermeasures and techniques that have been developed over the years to protect pilots from the potentially adverse consequences of high G flight, such as the G-suit and positive pressure breathing. The accumulated knowledge of human exposure to high G is drawn together within High G Flight, resulting in a definitive volume on the physiological effects of high G and their countermeasures.

Decision Making in Aviation (Hardcover, New Ed): Don Harris Decision Making in Aviation (Hardcover, New Ed)
Don Harris
R10,600 Discovery Miles 106 000 Ships in 10 - 15 working days

Decision making pervades every aspect of life: people make hundreds of decisions every day. The vast majority of these are trivial and without a right or wrong answer. In some respects there is also nothing extraordinary about pilot decision making. It is only the setting that is different - the underlying cognitive processes are just the same. However, it is the context and the consequences of a poor decision which serve to differentiate aeronautical decision making. Decisions on the flight deck are often made with incomplete information and while under time pressure. The implications for inadequate performance is much more serious than in many other professions. Poor decisions are implicated in over half of all aviation accidents. This volume contains key papers published over the last 25 years providing an overview of the major paradigms by which aeronautical decision making has been investigated. Furthermore, decision making does not occur in isolation. It is a joint function of the flight tasks; knowledge; equipment on the flight deck and other stressors. In this volume of collected papers, works from leading authors in the field consider all these aspects of aeronautical decision making.

R3,660 Discovery Miles 36 600 Ships in 10 - 15 working days

Aviation remains one of the most active and challenging domains for human factors and applied psychology. Since 1981, the biennial International Symposium on Aviation Psychology (ISAP) has been convened for the purposes of (a) presenting the latest research on human performance problems and opportunities within aviation systems, (b) envisioning design solutions that best utilize human capabilities for creating safe and efficient aviation systems, and (c) bringing together scientists, research sponsors, and operators in an effort to bridge the gap between research and application. Though rooted in the presentations of the 17th ISAP, held in 2013 in Dayton, Ohio, Advances in Aviation Psychology is not simply a collection of selected proceeding papers. Based upon the potential impact on emerging trends, current debates or enduring issues present in their work, select authors were invited to expand on their work following the benefit of interactions at the symposium. The invited authors include the featured keynote and plenary speakers who are all leading scientists and prominent researchers that were selected to participate at the symposium. These contributions are supplemented by additional contributors whose work best reflects significant developments in aviation psychology. Consequently the volume includes visions for the next generation of air management and air traffic control, the integration of unmanned (i.e. remotely piloted vehicles) into operational air spaces, and the use of advanced information technologies (e.g. synthetic task environments) for research and training. This book is the first in a series of volumes to be published in conjunction with each subsequent ISAP. The aim of each volume is not only to report the latest findings in aviation psychology but also to suggest new directions for advancing the field.

The revolutionary X-15 remains the fastest manned aircraft ever to fly. Built in the two decades following World War II, it was the most successful of the high-speed X-planes. The only recently broken 'sound barrier' was smashed completely by the X-15, which could hit Mach 6.7 and soar to altitudes above 350,000ft, beyond the edge of space. Several pilots qualified as astronauts by flying above 50 miles altitude in the X-15, including Neil Armstrong, the first man on the Moon. The three X-15s made 199 flights, testing new technologies and techniques which greatly eased America's entry into manned space travel, and made the Apollo missions and Space Shuttle viable propositions. With historical photographs and stunning digital artwork, this is the story of arguably the greatest of the X-Planes.

R493 R450 Discovery Miles 4 500 Save R43 (9%) Ships in 9 - 17 working days

Using specially commissioned artwork and detailing technical specifications, this book explores the Bf 109's different roles occasioned by wartime necessity, from its employment as a fighter to its evolution as a fighter-bomber. One of the principal types in the Luftwaffe's inventory at the beginning of World War II, the piston-engined Bf 109 was central to the many initial victories that the Germans achieved before coming up against the unbeatable RAF during the Battle of Britain. Nevertheless, by the second half of 1940 the Bf 109's operability was widened due to operational needs and it was flown as a fighter-bomber for precision attacks in Southern England. At first ad hoc conversions were made 'in the field' to allow the aircraft to carry a bomb or extra fuel tank. Such modifications were soon formalised by Messerschmitt, which created the Jabo Bf 109s. Drawing from pilots' first-hand accounts, author Malcolm V. Lowe explores the number of specialised units, including Lehrgeschwader 2 and dedicated fighter-bomber sections of standard fighter units such as 10. Staffel of Jagdgeschwader 26, which flew this highly specialised fighter-bomber. Including technical specifications, rare photographs and outstanding artwork, this book explores the Jabo versions of the Bf 109E, F and G both on the production line and with the addition of Rustsatze field conversion kits.

R3,106 Discovery Miles 31 060 Ships in 18 - 22 working days

This book provides an extensive overview of the protection of cultural heritages sites on the Moon (humanity's lunar heritage) and the various threats they face. First of all, the international legal framework, especially the relevant space treaties are analyzed in terms of how they protect cultural heritages sites on the Moon. In turn, the book explores key aspects like the application of customary law, the UNESCO World Heritage Convention, or the Underwater Convention, and the possibility of adding these sites to UNESCO's World Heritage list. The book subsequently addresses the question of how to define culture heritage sites or artifacts, in particular in view of the "Outstanding Universal Value" criterion, which is a vital aspect in order to differentiate them from space garbage or even space threats. Lastly, the book proposes and elaborates on various protection systems and multilateral protection regulations. Especially now, 50 years after the first human landing on the Moon, the book is a timely publication that will be of interest to all scholars and professionals working in the space field.

Luis Rodolfo Garcia Carrillo, Alejandro Enrique Dzul Lopez, Rogelio Lozano, Claude Pegard
R3,342 Discovery Miles 33 420 Ships in 18 - 22 working days

Quad Rotorcraft Control develops original control methods for the navigation and hovering flight of an autonomous mini-quad-rotor robotic helicopter. These methods use an imaging system and a combination of inertial and altitude sensors to localize and guide the movement of the unmanned aerial vehicle relative to its immediate environment.
The history, classification and applications of UAVs are introduced, followed by a description of modelling techniques for quad-rotors and the experimental platform itself. A control strategy for the improvement of attitude stabilization in quad-rotors is then proposed and tested in real-time experiments. The strategy, based on the use low-cost components and with experimentally-established robustness, avoids drift in the UAV s angular position by the addition of an internal control loop to each electronic speed controller ensuring that, during hovering flight, all four motors turn at almost the same speed. The quad-rotor s Euler angles being very close to the origin, other sensors like GPS or image-sensing equipment can be incorporated to perform autonomous positioning or trajectory-tracking tasks.
Two vision-based strategies, each designed to deal with a specific kind of mission, are introduced and separately tested. The first stabilizes the quad-rotor over a landing pad on the ground; it extracts the 3-dimensional position using homography estimation and derives translational velocity by optical flow calculation. The second combines colour-extraction and line-detection algorithms to control the quad-rotor s 3-dimensional position and achieves forward velocity regulation during a road-following task.
In order to estimate the translational-dynamical characteristics of the quad-rotor (relative position and translational velocity) as they evolve within a building or other unstructured, GPS-deprived environment, imaging, inertial and altitude sensors are combined in a state observer. The text give the reader a current view of the problems encountered in UAV control, specifically those relating to quad-rotor flying machines and it will interest researchers and graduate students working in that field. The vision-based control strategies presented help the reader to a better understanding of how an imaging system can be used to obtain the information required for performance of the hovering and navigation tasks ubiquitous in rotored UAV operation."

Mach Wave and Acoustical Wave Structure in Nonequilibrium Gas-Particle Flows (Paperback): Joseph T. C. Liu Mach Wave and Acoustical Wave Structure in Nonequilibrium Gas-Particle Flows (Paperback)
Joseph T. C. Liu
R583 Discovery Miles 5 830 Ships in 10 - 15 working days

In this Element, the gas-particle flow problem is formulated with momentum and thermal slip that introduces two relaxation times. Starting from acoustical propagation in a medium in equilibrium, the relaxation-wave equation in airfoil coordinates is derived though a Galilean transformation for uniform flow. Steady planar small perturbation supersonic flow is studied in detail according to Whitham's higher-order waves. The signals owing to wall boundary conditions are damped along the frozen-Mach wave, and are both damped and diffusive along an effective-intermediate Mach wave and diffusive along the equilibrium Mach wave where the bulk of the disturbance propagates. The surface pressure coefficient is obtained exactly for small-disturbance theory, but it is considerably simplified for the small particle-to-gas mass loading approximation, equivalent to a simple-wave approximation. Other relaxation-wave problems are discussed. Martian dust-storm properties in terms of gas-particle flow parameters are estimated.
