Book excerpt: An essential element in the Free Flight concept is the detection and avoidance of air traffic conflicts. A conflict occurs when the required separation between two aircraft, namely the ownership and the intruder, is lost. Conflict detection and resolution systems predict loss of separation and output conflict avoidance maneuvers that divert the ownership from its original trajectory. In this paper, we address the problem of redirecting the ownership to its original path, in a geometric optimal way, without introducing new conflicts. We call this concept Resolution and Recovery. Given the current 3-dimensional position and velocity vectors of two aircraft in predicted conflict and the ownership's required time of arrival at the target point, the resolution and recovery algorithm outputs a choice of maneuvers. Each maneuver comprises an escape course and a recovery course to be followed by the ownership. The escape course brings the ownership off the predicted conflict and the recovery course returns it to the original target point. We provide a rigorous mathematical description of the problem and show that the algorithm is correct, i.e., no matter which of the proposed maneuvers the ownership picks, it will arrive at the target point at the scheduled time while maintaining the minimum required separation to the intruder at all times.
Download or read book The Future of Air Traffic Control written by National Research Council and published by National Academies Press. This book was released on 1998-01-26 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automation in air traffic control may increase efficiency, but it also raises questions about adequate human control over automated systems. Following on the panel's first volume on air traffic control automation, Flight to the Future (NRC, 1997), this book focuses on the interaction of pilots and air traffic controllers, with a growing network of automated functions in the airspace system. The panel offers recommendations for development of human-centered automation, addressing key areas such as providing levels of automation that are appropriate to levels of risk, examining procedures for recovery from emergencies, free flight versus ground-based authority, and more. The book explores ways in which technology can build on human strengths and compensate for human vulnerabilities, minimizing both mistrust of automation and complacency about its abilities. The panel presents an overview of emerging technologies and trends toward automation within the national airspace systemâ€"in areas such as global positioning and other aspects of surveillance, flight information provided to pilots an controllers, collision avoidance, strategic long-term planning, and systems for training and maintenance. The book examines how to achieve better integration of research and development, including the importance of user involvement in air traffic control. It also discusses how to harmonize the wide range of functions in the national airspace system, with a detailed review of the free flight initiative.

Available in PDF, EPUB and Kindle. Book excerpt: th FM 2009, the 16 International Symposium on Formal Methods, marked the 10th an- versary of the First World Congress on Formal Methods that was held in 1999 in Toulouse, France. We wished to celebrate this by advertising and organizing FM 2009 as the Second World Congress in the FM series, aiming to once again bring together the formal methods communities from all over the world. The statistics displayed in the table on the next page include the number of countries represented by the Programme Committee members, as well as of the authors of submitted and accepted papers. Novel this year was a special track on tools and industrial applications. Subm- sions of papers on these topics were especially encouraged, but not given any special treatment. (It was just as hard to get a special track paper accepted as any other paper.) What we did promote, however, was a discussion of how originality, contri- tion, and soundness should be judged for these papers. The following questions were used by our Programme Committee.

Download or read book A New Approach for Disruption Management in Airline Operations Control written by António J. M. Castro and published by Springer. This book was released on 2014-06-19 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the research efforts dealing with airline scheduling have been done on off-line plan optimization. However, nowadays, with the increasingly complex and huge traffic at airports, the real challenge is how to react to unexpected events that may cause plan-disruptions, leading to flight delays. Moreover these disruptive events usually affect at least three different dimensions of the situation: the aircraft assigned to the flight, the crew assignment and often forgotten, the passengers’ journey and satisfaction. This book includes answers to this challenge and proposes the use of the Multi-agent System paradigm to rapidly compose a multi-faceted solution to the disruptive event taking into consideration possible preferences of those three key aspects of the problem. Negotiation protocols taking place between agents that are experts in solving the different problem dimensions, combination of different utility functions and not less important, the inclusion of the human in the automatic decision-making loop make MASDIMA, the system described in this book, well suited for real-life plan-disruption management applications.

Download or read book Green Aviation written by Emily S. Nelson and published by CRC Press. This book was released on 2018-06-12 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft emissions currently account for ~3.5% of all greenhouse gas emissions. The number of passenger miles has increased by 5% annually despite 9/11, two wars and gloomy economic conditions. Since aircraft have no viable alternative to the internal combustion engine, improvements in aircraft efficiency and alternative fuel development become essential. This book comprehensively covers the relevant issues in green aviation. Environmental impacts, technology advances, public policy and economics are intricately linked to the pace of development that will be realized in the coming decades. Experts from NASA, industry and academia review current technology development in green aviation that will carry the industry through 2025 and beyond. This includes increased efficiency through better propulsion systems, reduced drag airframes, advanced materials and operational changes. Clean combustion and emission control of noise, exhaust gases and particulates are also addressed through combustor design and the use of alternative fuels. Economic imperatives from aircraft lifetime and maintenance logistics dictate the drive for "drop-in" fuels, blending jet-grade and biofuel. New certification standards for alternative fuels are outlined. Life Cycle Assessments are used to evaluate worldwide biofuel approaches, highlighting that there is no single rational approach for sustainable buildup. In fact, unless local conditions are considered, the use of biofuels can create a net increase in environmental impact as a result of biofuel manufacturing processes. Governmental experts evaluate current and future regulations and their impact on green aviation. Sustainable approaches to biofuel development are discussed for locations around the globe, including the US, EU, Brazil, China and India.
