This book was released on 1999 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A quasi-experimental approach assessed the pilot performance comparability of simulator versus in-flight results. Flight data from three sleep-deprivation studies were pooled. Twenty aviators were included, 10 who flew a UH-60 helicopter simulator and 10 who flew a UH-60A aircraft under the influence of Dexedrine or placebo during 40 hours of continuous wakefulness. Performance on straight and levels, right and left turns, climbs and descents, and a left-descending turn (assessed at 0100, 0500, 0900, 1300, and 1700) tended to correspond in the simulator and aircraft. Generally, performance under Dexedrine was better than under placebo. However, only half of the maneuvers showed consistent, statistically significant stimulant/fatigue effects in both flight platforms. Measurement sensitivity was lower in the aircraft, likely because of error variance due to environmental influences (weather, temperature, and turbulence) and other factors (radio traffic and anxieties about safety). Thus, actual in-flight studies, while desirable in terms of face-validity, underestimate the impact of stressors such as fatigue on pilots.

Available in PDF, EPUB and Kindle. Book excerpt: To determine the efficacy and safety of using Dexedrine to sustain aviator performance during periods of sleep deprivation, a placebo-controlled study was conducted. Six U.S. Army helicopter pilots completed five, 1-hour flights in a specially-instrumented UH-60 simulator while their performance was evaluated via a computerized scoring system. Immediately following each flight, data were collected on electroencephalographic (EEG) activity, cognitive/psychomotor performance, and subjective mood ratings. The testing sessions began with flights at 0100, 0500, 0900, 1300, and 1700. One hour prior to each of the first three sessions on the drug-administration days, the aviators were given 10 mg of Dexedrine or placebo. Statistical analyses of the flight maneuvers revealed that Dexedrine improved aviator control on every maneuver with the exception of the hovering turns and the formation flight. Performance on the stationary hovers, the low level navigation, the climbs and descents, straight- and-level segments, standard-rate turns, and the left-descending turn all manifested at least one Dexedrine-related enhancement.

Book excerpt: Given its characteristics and the complexity of its use and its environment, the helicopter is exposed to damage and a whole series of measures can be previewed to alientate this risk. The presentations concentrated on five main topics: 1. Crew training; 2. The different conditions of use; 3. The psycho-physiological component; 4. Survival equipment and methods; and 5. Accidents and their prevention. A careful reading of the papers presented at the symposium will enable both specialists and decision-makers to make a summary assessment of the constraints of the missions on the one hand, and on the other, of the new methods of protection and training and the new technologies which will enable aircrew to carry out their missions in a safer environment. In addition, they will perhaps discover that helicopter operation can be optimised by a series of different devices and above all by judicious matching of "type of helicopter-type of aircrew training-type of additional on-board equipment".

Download or read book Aerospace Health and Safety: Today and the Future written by Irina Mordukhovich and published by Frontiers Media SA. This book was released on 2023-11-20 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aviation plays vital roles in commerce, defense, science and leisure travel. Irrespective of the purpose of flight, crew and passengers are challenged by exposure to a variety of environmental conditions that can differ widely from work and travel environments on the surface of the Earth. With anticipated changes in aviation and space technology, new challenges to health and safety of crew and passengers can be expected. In this Research Topic, we welcome contributions from those whose work and interests are relevant to the health and safety of crew and passengers. This includes, but is not limited to, health and safety professionals, FAA examiners, corporate medical officers, aerospace and occupational physicians, physiologists, military and scientific team members, public health professionals, as well as engineers who are tasked with crew and passenger health and safety design projects. While 4.1 billion passengers fly on commercial airlines annually (and this figure is even higher when taking into account privately owned aircraft and military flight), for the most part aviation is safe. Passengers do arrive at their destinations with little concern to their own well-being and flight is generally well tolerated. However, older flyers, people with (diagnosed or undiagnosed) preexisting disease, and other vulnerable passengers (such as young children and pregnant women) may be at risk of complications and crew may be at special risk due to the frequency and duration of their many flight-related exposures. Health and safety issues for crew and passengers include but are not limited to: potentially severe circadian rhythm disruption, potential health effects of low-level cosmic ionizing radiation exposure at altitude, reduced oxygen delivery and tissue hypoxia at cabin pressurization, cabin air contamination by engine gases, toxic materials used in uniforms and some cabin seat materials, occupational noise, pesticides used for cabin disinsection, lack of adequate crew rest on layovers or between flights, cardiovascular demands of flight and effects of flight-related dehydration, the current absence of screening protocols especially in the context of a rising number of elderly and vulnerable flyers, lack of healthy nutrition at airports and in flight, availability of food and hydration as well as adequate cabin temperature under delay conditions, effects of alcohol use on flight-related physiological and behavioral health risks, anxiety and psychological distress associated with air travel, the effects of long-haul or ultra-long-haul flights on thromboembolic events as well as smoking cessation efforts and related psychological outcomes, job-related stress and harassment among crew. Cosmic ionizing and non-ionizing radiation exposure have drawn attention as have historic exposures of crew and passengers to second-hand cigarette smoke. The threat of political and interpersonal violence and altercations involving aviation cannot be overlooked. On-board medical emergencies run a wide gamut and the capacity to respond becomes more problematic as the duration of flights becomes longer or in the case of flight over oceans and the poles. In addition, in-flight and post flight embolisms and myocardial infarctions are more prevalent than might be expected. We hence encourage manuscripts that address in-flight medical response, including the capabilities on different types of aircraft on potential interventions by crew and medical volunteers. In addition, aviation as a vector for the carriage of disease is a significant concern to public health and security of populations world-wide, and we welcome submissions regarding infectious disease epidemiology and medicine as it relates to air travel. Insects and occasional unplanned travel by birds and rodents can present additional public health concerns. We are approaching an era where space travel may soon be increasingly common. Future flights for near-Earth orbit by leisure travelers and as well as travel to the moon and Mars raise a host of new questions with health and safety implications. What are the proposed health and safety accommodations going to be? Who will be allowed to travel? Perhaps the most interesting question is - who will make the rules?

Download or read book Monitoring Metabolic Status written by Institute of Medicine and published by National Academies Press. This book was released on 2004-07-29 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. military's concerns about the individual combat service member's ability to avoid performance degradation, in conjunction with the need to maintain both mental and physical capabilities in highly stressful situations, have led to and interest in developing methods by which commanders can monitor the status of the combat service members in the field. This report examines appropriate biological markers, monitoring technologies currently available and in need of development, and appropriate algorithms to interpret the data obtained in order to provide information for command decisions relative to the physiological "readiness" of each combat service member. More specifically, this report also provides responses to questions posed by the military relative to monitoring the metabolic regulation during prolonged, exhaustive efforts, where nutrition/hydration and repair mechanisms may be mismatched to intakes and rest, or where specific metabolic derangements are present.

Available in PDF, EPUB and Kindle. Book excerpt: Taking Precautions Against Fatigue in Aviation Pilot fatigue is a significant problem in modern aviation operations, largely because of the unpredictable work hours, long duty periods, circadian disruptions, and insufficient sleep that are commonplace in both civilian and military flight operations. The full impact of fatigue is often underappreciated, but many of its deleterious effects have long been known. Compared to people who are well-rested, people who are sleep deprived think and move more slowly, make more mistakes and have memory difficulties. These negative effects may and do lead to aviation errors and accidents. In the 1930s, flight time limitations suggested lay-over durations, and aircrew sleep recommendations were developed in an attempt to mitigate aircrew fatigue. Unfortunately, there have been few changes to aircrew scheduling provisions and flight time limitations since the time they were first introduced, despite evidence that updates are needed. Although the scientific understanding of fatigue, sleep, shift work, and circadian physiology has advanced significantly over the past several decades, current regulations and industry practices have in large part failed to adequately incorporate the new knowledge.

This book was released on 2012-01-30 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.
