Book Description
Fatigue occurs under cyclic loading and can significantly degrade the operational capability and safety of metallic aircraft components and structures. This book provides summaries of some metallic aircraft structural integrity issues, innovative but established examples of maintaining operational capability—airworthiness, and assessments of safe in-service fatigue lives. These topics are based on a through-life fatigue management philosophy that ensures safe and continued operation, including during life extensions that are almost inevitably required. This philosophy is underpinned by observations of the behaviour of fatigue cracks in actual structures subjected to realistic service loading conditions. The book includes topics like aircraft design requirements, individual aircraft fatigue loads monitoring, airframe fatigue testing, sources of fatigue-nucleating discontinuities, and prediction of fatigue crack growth from these discontinuities. All these aspects contribute to discussing methods of assuring the structural integrity and operational capability of realistically cracked structures. The book also discusses the exponential behaviour of lead or dominant cracks—those leading to first failure—and the practical significance of differences between fatigue fracture topographies produced under constant amplitude and variable amplitude loading. The book can be a valuable reference for researchers and professionals interested in aircraft fatigue management and allied fields.

Book Description
This updated edition includes fatigue and sleep definitions as well as strategies for the measurement and assessment of fatigue. The aviation performance, mood, and safety problems associated with sleep restriction and circadian disruptions in operational settings are highlighted. The biological bases of fatigue are discussed so that the reader can understand that it is a real physiological phenomenon and not 'just a state of mind'. Both traditional and newly-developed scientifically-valid countermeasures are presented, and a variety of data from diverse sources are included to provide readers with a 'toolbox' from which they can choose the best solutions for the fatigue-related problems that exist in their unique operational context. In addition, an essential overview of Fatigue Risk Management Systems is included to provide the basic structure necessary to build and validate a modern, integrated approach to successful fatigue management. The book is of interest to aviation crews in both civilian and military sectors--managers as well as pilots, flight crews, and maintainers. It aims to be user-friendly, although scientific information is included to help the reader fully understand the 'fatigue phenomenon' from an evidence-based perspective as well as to enhance the reader's appreciation for the manner in which various counter-fatigue interventions are helpful.

Book Description
Nearly everyone experiences fatigue, but some professions--such as aviation, medicine and the military--demand alert, precise, rapid, and well-informed decision making and communication with little margin for error. The potential for fatigue to negatively affect human performance is well established. Concern about this potential in the aviation context extends back decades, with both airlines and pilots agreeing that fatigue is a safety concern. A more recent consideration is whether and how pilot commuting, conducted in a pilot's off-duty time, may affect fatigue during flight duty. In summer 2010 the U.S. Congress directed the Federal Aviation Administration (FAA) to update the federal regulations that govern pilot flight and duty time, taking into account recent research related to sleep and fatigue. As part of their directive, Congress also instructed FAA to have the National Academy of Sciences conduct a study on the effects of commuting on pilot fatigue. The Effects of Commuting on Pilot Fatigue reviews research and other information related to the prevalence and characteristics of commuting; to the science of sleep, fatigue, and circadian rhythms; to airline and regulatory oversight policies; and to pilot and airline practices. The Effects of Commuting on Pilot Fatigue discusses the policy, economic, and regulatory issues that affect pilot commuting, and outlines potential next steps, including recommendations for regulatory or administrative actions, or further research by the FAA.

Book Description
Practical Human Factors for Pilots bridges the divide between human factors research and one of the key industries that this research is meant to benefit—civil aviation. Human factors are now recognized as being at the core of aviation safety and the training syllabus that flight crew trainees have to follow reflects that. This book will help student pilots pass exams in human performance and limitations, successfully undergo multi-crew cooperation training and crew resource management (CRM) training, and prepare them for assessment in non-technical skills during operator and license proficiency checks in the simulator, and during line checks when operating flights. Each chapter begins with an explanation of the relevant science behind that particular subject, along with mini-case studies that demonstrate its relevance to commercial flight operations. Of particular focus are practical tools and techniques that students can learn in order to improve their performance as well as "training tips" for the instructor. - Provides practical, evidence-based guidance on issues often at the root of aircraft accidents - Uses international regulatory material - Includes concepts and theories that have practical relevance to flight operations - Covers relevant topics in a step-by-step manner, describing how they apply to flight operations - Demonstrates how human decision-making has been implicated in air accidents and equips the reader with tools to mitigate these risks - Gives instructors a reliable knowledge base on which to design and deliver effective training - Summarizes the current state of human factors, training, and assessment
