Is this an overture to the page-turner of success or endless soap-opera of debacle? Nobody yet invented the universal formula that govern the provision of air navigation services for any given combination of air traffic flow, its variability and complexity, airspace configuration and operational environment. It is only certain that the magic formula should in order to fit snugly in any case, simultaneously consider variables of people, procedures, systems and environment. The authors of this book are proving the statement as their contributions focus on developments in the field of air navigation services from a wealth of particular different aspects. Actually it is all about competent people that communicate to each other supported by technology providing them necessary information for orchestrated coordination of glorious dance of safely separated aircraft. Since the weakest link in the chain is the human, it is envisaged that systems themselves should communicate. However, machines are not yet able to think nor improvise for brilliant lifesaving solutions in cases of emergencies. For the time, the air navigation services and especially air traffic (control and management) services will remain human oriented but technology driven endeavour. Provision of air navigation services entered a new era of performance scheme. The performance scheme provides binding targets on four key performance areas of safety, capacity, environment and cost-efficiency. It is imposed that targets are fully achieved, but it is not prescribed how, this being typical for the performance based and goal oriented regulation. Those key performance areas are interlaced by proportional and inversely proportional interdependencies. Namely, for example and simplified into one sentence; if one aims to increase sector capacity with existing human resources (constant staff costs) and not investing into the technology (constant support cost) to achieve improved cost-efficiency of service provision, the resulting overloaded system might unlock the Pandora box of latent safety issues. Since failure is not an option, we – the general, migrating and traveling public, airspace users, airport operators, air navigation services providers and the economy – will gain attaining the goals of X Preface performance scheme in the process. However, un-answered cardinal question is what is the winning strategy? This book provides do-not-forget-peculiarities insight into the elements of new business model of air navigation services provision as evolution of the latter became essential. It was a pleasure editing this book and I am sincerely grateful to all the authors for their efforts invested into the future of air navigation services represented by this book.
