Reardon and published by . This book was released on 1996-12-01 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the effects of the four combinations of unencumbered MOPPO aviator battle dress uniform (ABDU) and encumbered MOPP4 over ABDU flight ensembles in cool (70 degrees F, 50 percent relative humidity (RH)) and hot (100 degrees F, 50 percent RH) UH-60 cockpit conditions. This report describes the physiological and psychological responses. The most striking, operationally relevant result was that none of the crews in the encumbered MOPP4 hot condition were able to complete the first two 2-hour sorties movements. The results of this evaluation suggest that future rotary-wing aviator flight uniform components should be designed to be lighter weight and allow greater evaporation of sweat. Methods should be sought to improve fit and comfort, particularly for the mask and helmet combination, as well as prevent pressure discomfort over the back due to the life raft. The 11.7 lb ballistic protective plate also should be lighter weight and reduced in thickness. Forced dry air microclimate cooling into the ensemble should be considered for reducing heat accumulation in the encumbered MOPP4 aviator ensemble by enhancing evaporative cooling and thereby increasing endurance times during hot weather operations.

Download or read book Resource Utilization and Development written by Shri Kamal Sharma and published by Northern Book Centre. This book was released on 1992 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between resources and development is the pivot around which the present study revolves. Focussing on the process of resource creation and utilization it emphasizes the need of equitable development integrating local needs, resources, people and functions. The resource exploitation and their utilization are two independent economic activities influenced by different algorithms and usually have manifested in core-periphery relationship. Reviews the persistent problems of economic development in perspective of exploitation of natural resources with the objective to provide some clues for occurrence and persistence of regional disparities and for suggesting a development model synchronising both the resource management and environmental protection.

Download or read book Psychological Effects of Chemical Defense Ensemble Imposed Heat Stress on Army Aviators written by and published by . This book was released on 1982 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Psychological testing was conducted with six Army aviators before and after flights in a UH-1H helicopter while wearing standard flight suits, US or UK aircrew chemical defense ensembles. Additional testing on non-flight days was conducted to provide a baseline for evaluation. Tests consisted of encode/decode problems, math problems, logical reasoning problems, target detection problems, and a four-choice reaction time test. Tests were scored for number of attempted, percent correct, reaction time of correct and incorrect responses. Self reports of mood were also taken and scored. The results of the study indicated that various levels of ensemble-imposed heat stress caused orderly changes in psychological function and extended the results of laboratory investigations to the aviation setting. In addition, reaction time data showed changes in the pilot's ability to deal with 'error' situations as a function of imposed heat stress and that self reports of mood were unreliable indicators of severe heat stress.
Book Synopsis Effects of Microclimate Cooling on Physiology and Performance While Flying the UH-60 Helicopter Simulator in NBC Conditions in a Controlled Heat Environment by :
Download or read book Effects of Microclimate Cooling on Physiology and Performance While Flying the UH-60 Helicopter Simulator in NBC Conditions in a Controlled Heat Environment written by and published by . This book was released on 1992 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of microclimate cooling on aviator performance and physiology in nuclear, biological, and chemical (NBC) individual protective equipment (IPE) were evaluated in the USAARL UH-60 research flight simulator. Sixteen male aviators flew the simulator in two temperature conditions, 95 deg F and 105 deg F, both at 50 percent relative humidity (RH). Two thermoelectric conditioning units were used, one providing cooled blown air, the other cooled water to the aviators. At each temperature, they flew for up to 6 hours in NBC IPE with no cooling, air cooling, and liquid cooling. There was an extra condition at 105 deg F when vent air with no cooling was blown through the air vest, making a total of seven test conditions. There were significant improvements in flight performance as a result of the cooling, more so at the higher temperature. Also, there were differences between the two cooling systems at 105 deg F, with the air system producing significantly lower flight error rates. Survival time was based on the length of time each subject stayed in the condition before reaching physiological withdrawal criteria (rectal temperature of 39 deg C or heart rate of 150 beats per minute for 15 minutes) or exercising their option to retire early. There were considerable increases in survival time with the use of microclimate cooling. The mean survival time at 95 deg F was increased to 385 minutes with the liquid system from 285 minutes without cooling. At 105 deg F to 333 minutes for the air system from 79 minutes with no cooling, the improvement was even more dramatic. There were significant differences between the two cooling systems at 105 deg F with the air system producing longer survival times.
Book Synopsis Heat Stress Evaluation of Special Operations Aviation Regiment and Air Warrior Concept 1 and 3 Aviator Ensembles in a UH-60 Simulator by : Matthew Reardon
Download or read book Heat Stress Evaluation of Special Operations Aviation Regiment and Air Warrior Concept 1 and 3 Aviator Ensembles in a UH-60 Simulator written by Matthew Reardon and published by . This book was released on 1999-03-01 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This aviator heat stress study used a mixed between/within test subject design with one environmental condition (hot) and three rotary-wing MOPP4 ensembles (Special Operations Aviation Regiment SOAR), Air Warrior Concept 1, and Air Warrior Concept 3) encumbered with ballistic protection and over- water survival components. The SOAR ensemble was tested with (SC) and without (SX) microclimate cooling (MCC) consisting of a water-cooled undershirt with portable refrigerator/pump. Air Warrior Concept 1 and Concept 3 aviator MOPP4 ensembles were tested with (AC) and without (AX) MCC, respectively. Physiological and subjective data were obtained to compare thermoregulatory responses and quantitate the benefits of microclimate cooling. Test sessions consisted of a 20-minute treadmill walk in a heated (100 deg F and 20 percent relative humidity RH) environmental chamber to stimulate outdoor preflight activities, followed by three 2-hour sorties in a research UH-60 simulator with cockpit conditions set at 1000F and 50 percent RH (90 deg F wet-bulb globe temperature WBGT).
Book Synopsis Effects of Physiologic Heat Stress on Cognitive Performance During Simulated Flight Tasks by :
Download or read book Effects of Physiologic Heat Stress on Cognitive Performance During Simulated Flight Tasks written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is known that heat stress leads to reduced +Gz-tolerance in tactical aircrew. The first phase of an effort to determine the relationship between physiologic heat stress and flight performance was conducted using the new NAWCADPAX flight simulator installed in an environmental chamber. Performance scores declined after subjects were exposed to the hot alert conditions relative to control, though the difference was not statistically significant. Correlation analysis indicated a marginal relationship between the change in performance and rectal and mean skin temperatures (r = 0.59 and 0.55, respectively). The experimental design did not account for the increased generation of metabolic heat associated with straining against high G forces, though it did include radiant heat loads. The next phase will include physical work in the cockpit to account for this additional factor.

Book Synopsis The Effects of 37 Hours of Continuous Wakefulness on the Physiological Arousal, Cognitive Performance, Self-Reported Mood, and Simulator Flight Performance of F-117A Pilots by :
Download or read book The Effects of 37 Hours of Continuous Wakefulness on the Physiological Arousal, Cognitive Performance, Self-Reported Mood, and Simulator Flight Performance of F-117A Pilots written by and published by . This book was released on 2003 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 30 years, fatigue has contributed to a number of Air Force mishaps. Resource cutbacks combined with increased operational tempos, sustained operations, and night fighting could exacerbate the problem. Extended wakefulness and circadian factors can be especially problematic in military aviation where mission demands sometimes necessitate flights as long as 17-44 hours. To effectively counter fatigue in such operations, the effects of this threat must be objectively measured and understood. This study assessed F-117A pilots during a 37-hour period of continuous wakefulness. Although none of the pilots crashed, substantial decrements were found in flight-skills, reaction times, mood, and brain activation as early as after the 26% hour of continuous wakefulness. The greatest flight degradations occurred after 27-33 hours awake, even though many pilots believed their worst performance was earlier. The decrements found in this relatively-benign test environment may be more serious under operational conditions unless personnel anticipate the most dangerous times and administer valid fatigue countermeasures.

Download or read book Loss of Signal written by Philip Stepaniak and published by CreateSpace. This book was released on 2015-05-09 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Loss of Signal, a NASA publication to be available in May 2014, presents the aeromedical lessons learned from the Columbia accident that will enhance crew safety and survival on human space flight missions. These lessons were presented to limited audiences at three separate Aerospace Medical Association (AsMA) conferences: in 2004 in Anchorage, Alaska, on the causes of the accident; in 2005 in Kansas City, Missouri, on the response, recovery, and identification aspects of the investigation; and in 2011, again in Anchorage, Alaska, on future implications for human space flight. As we embark on the development of new spacefaring vehicles through both government and commercial efforts, the NASA Johnson Space Center Human Health and Performance Directorate is continuing to make this information available to a wider audience engaged in the design and development of future space vehicles. Loss of Signal summarizes and consolidates the aeromedical impacts of the Columbia mishap process-the response, recovery, identification, investigative studies, medical and legal forensic analysis, and future preparation that are needed to respond to spacecraft mishaps. The goals of this book are to provide an account of the aeromedical aspects of the Columbia accident and the investigation that followed, and to encourage aerospace medical specialists to continue to capture information, learn from it, and improve procedures and spacecraft designs for the safety of future crews.
