Human Systems Integration Capstone. / Unlimited distribution. / Expeditionary Helicopter Sea Combat Squadrons (HSC) operate on Navy amphibious assault ships to provide search and rescue (SAR), logistics and combat support. When embarked, the detachments are the primary SAR asset and have requirements levied upon them by NAVAIR 00-80T-106 to maintain aircraft SAR readiness postures in support of ship and embarked Marine Corps aircraft operations. The goal of this study was to identify what impacts would occur to flight support personnel effectiveness if OPNAV 3710.7U sleep requirements were deviated from in order to meet minimum personnel requirements. The conclusion reached was that safety concerns are present when OPNAV 3710.7U sleep requirements for flight support personnel are violated to maintain NAVAIR 00-80T-106 operational requirements. The study found that worker effectiveness varies systematically with the duration of sleep interruption encountered. Minimum predicted effectiveness comes at three hours with the predicted values at two, three and four hours being essentially equal. When sleep interruptions exceed 1.55 hours, effectiveness levels drop below 70%, equivalent to experiencing a .08 BAC. A model for subsequent interruptions over the preceding days found that worker effectiveness varies systematically with the number of days between interruptions. The effect of sleep interruptions of multiple nights was greatest two days between interruptions. A minimum of four to five days between sleep interruptions is required for interruption effects to not be cumulative.

Introduction: Obesity, and in particular central fat accumulation, is associated with a number of metabolic disturbances such as dyslipidaemia and insulin resistance. Such `clustering' of factors is known as the Insulin ResistanceS yndrome( IRS). More recently, hypofibrinolysisa s a resulto f elevated concentrations of PAI-1 at rest has been included in the IRS. Acute exercise in normal weight individuals results in an increase in fibrinolytic capacity due to a rise in t-PA and a reduction in PAI-1 concentrations. The primary aim of the following studies therefore was to determine the effect of acute exercise and exercise training on fibrinolytic markers in obese populations. The secondary aim of this work was to examine the relationships between PAI-1 concentrations and other markers of the IRS to determine a potential role for these factors in the short-term regulation of plasma PAI-1 concentrations. Methods: Premenopausal female and male overweight and obese volunteers underwent acute bouts of exercise at intensities ranging from 50% to 100% V02 max A group of obese premenopausal omen also underwent a graded maximal exerciset est to exhaustionb efore and after 12 weeks of exercise training at 50% or 70% VO2 max. Venous blood samples were taken at rest, immediately post exercise and up to 2 hours post exercise. Samples were analysed for fibrinolytic factors (t-PA, total PAI-1 & active PAI-1), markers of endothelial damage (vWF) as well as other components of the IRS including lipid profiles, insulin and leptin. Results: Plasma t-PA concentrations rose with acute exercise at intensities greater than 50% V02 max in all study populations with the exception of obese sedentary males. In all cases t-PA returned to baseline levels 30 minutes post exercise. None of the protocols administered were sufficient to lower total PAI-1 concentrations immediately post exercise but exercise at an intensity of 70% V02 max and a duration of greater than 30 minutes resulted in elevated PAI-1 concentrations 30 minutes post exercise in the overweight and obese populations. Active PAI-1 concentrations decreased with exercise either immediately or within 30 minutes post exercise at an intensity of 70% V02 max and durations greater than 30 minutes. Exercise training at both 50% and 70% V02 max increased the t-PA response to maximal exercise but only exercise training at 70% V02 max resulted in greater decrease in active PAI-1 with exercise. No factors were consistently associated with PAI-1 throughout the studies although anthropometric measures and blood pressure were regularly associated with PAI-1 at rest. Conclusions: Overall, exercise at an intensity of 70% V02 max for duration of at least 30 minutes in obese populations results in an increased fibrinolytic capacity as shown by elevated t- PA concentrations and decreased active PAI-1 concentrations. It is important to remember however that obese populations still remain hypofibrinolytic with respect to non-obese populations at rest, during exercise and in the recovery period.

Civil aviation provides for large scale, rapid, safe and reliable transport over long distances. In the last half of the 20th century, the reliability of air transport has increased, safety has improved and costs have reduced: the volume of civil aviation has greatly increased and demand continues to rise. The social and economic benefits arising from aviation are substantial while its environmental costs are significant and increasing: with current technologies aviation is considered to be essentially unsustainable. Sustainable development as a concept, arose in the latter part of the 20th century. It may be regarded as a journey of changes through time, a journey navigating a wide range of changes in technology and behaviour thought to be needed to move towards a better level of sustainability. There is a need to apply the principles of sustainable development to the practice of the civil aviation industry. The research on which this thesis is based draws on sustainable development literature, general systems theory and quality principles to derive a holistic and systemic sustainable development model, and a methodology for deriving indicators of sustainable development. These are then applied to the civil aviation system, to select and construct indicators of sustainable development in civil aviation. The indicator selection process is participative, and seeks the views of stakeholders of UK civil aviation. Stakeholders are asked, via a Delphi study, to give their views on the meaning of sustainable aviation, and on the most important aspects of sustainable development in civil aviation. The research proposes a set of 29 indicators for sustainable development in civil aviation, including institutional and regulatory indicators. The research findings suggest that, amongst UK civil aviation stakeholders, there is some consensus on the important sustainability issues facing civil aviation, and on their choice of indicators. There is little understanding of the meaning of sustainable aviation, and disagreement on policies to adopt in favour of sustainable development in aviation. Amongst stakeholders from civil aviation organisations, there is strong opposition to regulatory or economic policies in favour of sustainable development. While the safety of civil aviation is institutionalised, there is evidence to suggest that opposition to other aspects of sustainable development is embedded in the regulatory and operational organisations of civil aviation in the UK.

This thesis examines the liberalisation of the European Community's civil aviation industry and attempts to measure how effective this process has been in achieving its goal of increased competition and greater efficiency. Using the experience in the United States following deregulation of domestic air transport services as a template, the study employs Easton's model of political analysis and Porter's model of competitive forces as a framework for empirical research. This research was carried out with a representative sample of EC airlines, of their suppliers and customers, of providers of substitute services and of the industry's regulators. The results of the research were validated by personal interviews with leading stakeholders in the industry. The main Conclusions drawn from the research are that: i. liberalisation of the European Community air transport market has resulted in an influx of new entrants, an increase in the number of routes operated and a wider availability of discounted fares; ii. to the extent that competition has nevertheless been less fierce than anticipated, this is because the aims of liberalisation have been frustrated by a resistance to change on the part of certain Member States and by the European Commission's inability to prevent further grants of State aid to loss-making flag carriers. Inadequate infrastructure has also acted as a brake on competition; iii. customer choice is strongly influenced by frequency of service and by price. Those airlines which have set out to gain market share and which have pursued low price strategies have benefited most from liberalisation; iv. airlines benefit from selling to a large number of buyers and from having a wide choice of suppliers; V. the only threat of substitution to air travel within the European Community is from the High Speed Train and then only over comparatively short distances.

Safety Management Systems (SMS) are becoming the industry standard for safety management throughout the aviation industry. As the Federal Aviation Administration (FAA) continues to mandate SMS for different segments, the assessment of an organization’s safety culture becomes more important. An SMS can facilitate the development of a strong aviation safety culture. This study describes basic principles and components of an SMS and how safety culture and SMS are integrated. Studies focusing on safety culture assessment were identified for other industries as well as for different areas of the aviation industry. The purpose of this study was to examine the relationship between an organization’s safety culture and SMS implementation in collegiate flight schools. The research study was designed to determine (a) relationship between SMS implementation and safety culture, (b) the relationship between safety promotion and safety culture, and (c) the relationship between management commitment and safety culture. The study population consisted of 453 individuals at 13 collegiate flight schools. Data were gathered through an online survey to safety officers at collegiate flight schools within the University Aviation Association to determine the level of SMS implementation; and the Collegiate Aviation Program Safety Culture Survey (CAPSCUS) was used to measure the safety culture at those collegiate flight schools. The results indicated that a relationship existed between SMS implementation and safety culture, safety promotion and safety culture, management commitment and safety culture. The relationship for all three was more prominent within the Formal Safety Program major scale of the CAPSCUS. It is recommended that collegiate flight schools examine their existing level of SMS, management commitment, and their safety promotion and assess safety culture within their institution. Future studies should be done to further examine the relationship between SMS implementation and safety culture so that the collegiate flight training environment would have guidance regarding SMS implementation.
