Book Description
A study of safety reports was conducted to examine the hypothesis that fatigue and associated performance decrements occur in air transport operations, and that these are associated with some combination of factors: circadian desynchronosis, duty time; pre-duty activity; sleep; work scheduling; workload; and environmental deprivation. The findings are based on a selected sample of reported incidents in which the reporter associated fatigue with the occurrence. In comparing the fatigue reports with a control set, significant performance decrements were found to exist related to time-of-day, awareness and attention to duty, less significantly, final phases of flights. The majority of the fatigue incidents involved such unsafe events as altitude deviations, takeoffs and landing without clearance, and the like. Considerations of duty and sleep are the major factors in the reported fatigue conditions. Lyman, E. G. and Orlady, H. W. Unspecified Center NASA-CR-166167 NAS2-10060; RTOP 505-35-41...

Book Description
"Pilot fatigue and circadian desynchronosis, its significance to air transport safety, and research approaches, were examined. There is a need for better data on sleep, activity, and other pertinent factors from pilots flying a variety of demanding schedules. Simulation studies of flight crew performance should be utilized to determine the degree of fatigue induced by demanding schedules and to delineate more precisely the factors responsible for performance decrements in flight and to test solutions proposed to resolve problems induced by fatigue and desynchronosis. It was concluded that there is a safety problem of uncertain magnitude due to transmeridian flying and a potential problem due to fatigue associated with various factors found in air transport operations."--NTRS site.

Book Description
This overview of fatigue includes fatigue definitions, the measurement / assessment of fatigue, and the performance, mood, and safety problems associated with fatigue in the operational setting. The physiological bases of fatigue are discussed, so the reader understands that fatigue is a physiological phenomenon that is not "just a state of mind". Scientifically-valid countermeasures are discussed and data from a variety of sources are included to provide readers with a "toolbox" from which they can choose solutions to fatigue-related problems. The book is of interest to aviation crews in both civilian and military sectors, managers as well as aviators, flight deck as well as maintenance crews. It aims to be 'user-friendly', although scientific information is included to help the reader understand why certain behaviours occur.

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
While stress and fatigue are often dealt with in other books on aviation performance and human factors, these realities of human vulnerability are now increasingly seen as central to the effective conduct of flight operations. Flight Stress provides a comprehensive treatment and a better understanding of stress and fatigue as they relate to aviation. It clarifies and distinguishes the concepts of stress and fatigue as they apply to flight, and expounds sufficient theory to provide a principled basis for the consideration and amelioration of stress effects in aviation. The authors examine what is known of the effects of stress from both laboratory and operational studies and detail the aspects of this knowledge to which aviation professionals should pay most attention. They go on to discuss the implications of stress and fatigue for performance in a range of aviation contexts, from air traffic control to aerial combat. Physiological, cognitive and medical sequel are explored. The book locates aviation related work, in its broader research context, critically reviewing and illustrating the work, with examples from accident and incident reports. It is substantive but accessible, since it both sets out the research base and provides plenty of 'real world' examples to leaven and illustrate the narrative. It thus provides an authoritative handbook for aviation professionals and a comprehensive source book and reference work for researchers. The readership includes aviation professionals and researchers, including medical personnel and registered Aviation Medical Examiners; psychologists and Human Factors specialists; training captains, senior pilots and engineers; air traffic controllers, dispatchers and operations staff.

Book Description
Fatigue encountered in airlifts to foreign military operations can be severe enough to pose a flight safety hazard. This study is an attempt to document to what extent fatigue (and time zone changes of five & six hours) can impact on aircrew performance during routine re-supply missions to former Yugoslavia. In the first phase of the study, aircrew sleep hygiene was assessed immediately prior to & throughout ten missions to Bosnia. Aircrew psychomotor performance was also assessed during flight. Phase two involved a laboratory-based fatigue countermeasure study in which melatonin and zopiclone were evaluated as facilitators of early circadian sleep. In this phase, residual effects of these medications on aircrew performance after sleep were also studied. The final phase was an operational evaluation of the lab-proven countermeasures in 70 missions to Bosnia. The performance of aircrew using the medications is compared to performance using placebos. At the close of this phase, a laboratory study also compared a new short-acting sleep medication, zaleplon, against two other sleep medications (zopiclone and temazepam) and melatonin in order to quantify the depth of their respective impacts on psychomotor performance and the post-ingestion time required for return to normal performance.

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.
