2nd Edition

Fatigue in Aviation A Guide to Staying Awake at the Stick

By John Caldwell, J. Lynn Caldwell Copyright 2016

    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.

    Contents: Part I The Problem of Fatigue: Introduction; An overview of fatigue.

He is an internationally recognized expert scientist in the areas of sleep deprivation, fatigue countermeasures, and research on the real-world performance effects of select pharmacological compounds. He is a Fellow in the Aerospace Medical Association and the Aerospace Human Factors Association. Among his awards, Dr. Caldwell has received the Air Force's highest civilian award for research and development.

    Dr. J. Lynn Caldwell has a Ph.D. in Experimental Psychology with over 20 years of experience investigating sleep-optimization and fatigue-mitigation strategies in military aviation. She is certified by the American Board of Sleep Medicine as a Sleep Specialist. In her work with the U.S. Army, U.S. Air Force, and U.S. Navy, Dr Caldwell has conducted numerous simulator and in-flight investigations on fatigue countermeasures, sleep, circadian rhythms, and pharmacological interventions in rated military pilots. She has served as a Distinguished Visiting Scholar at the U.S. Air Force Academy, and is a Fellow of the American Academy of Sleep Medicine, the Aerospace Medical Association, and the Aerospace Human Factors Association.

    Comments on previous edition: 'The Caldwells have written an easy to read book that translates scientific findings on fatigue into practical and effective strategies that will improve alertness and performance in flight ops. Aviation professionals--including flight crew, cabin crew, maintenance personnel, schedulers, safety professionals, and all levels of managers--should read this excellent book and use the information to reduce known fatigue-related risks and enhance flight safety.' Mark R. Rosekind, President and Chief Scientist, Alertness Solutions and Former Director, NASA Fatigue Countermeasures Program, USA '...by means of practical examples, some very lively, the scientific jargon surrounding the issue of fatigue becomes very familiar...very interesting' Aerlines Magazine June 2004 'Fatigue in Aviation is wholeheartedly recommended - for flight crews and everyone else in aviation whose work impacts the lives of others: security; maintenance; emergency services; airline management; air traffic control....and, indeed, for anyone who's ever had a bad night's sleep.'
