Approved for public release; distribution is unlimited / The conversion to hydrogen as a naval aviation fuel would allow for independence on fuel cost and supply, as hydrogen is globally accessible. The biggest obstacle to using hydrogen is its very low density, a property that even combined with hydrogen's high heat of combustion still results in very large fuel tanks. Liquid hydrogen (LH2) with its higher density would still require a larger volume than kerosene for the aircraft to achieve the same mission. Another problem with using LH2 is its cryogenic nature, a property that requires complicated fuel tanks and more careful fueling. A design study has been conducted for this report to determine the feasibility of using LH2. A Lockheed-Martin P-3 Orion configuration was modified to accommodate LH2 as its fuel, its mission parameters kept unchanged. It is concluded from this design study that using LH2 would significantly limit the amount of usable cabin space, as the fuel tank takes up 65% of the aircraft's internal volume. Despite the large LH2 tank weight of about 14,865lb, due to the low fuel weight the aircraft's takeoff gross weight is only 113,646lb, about 80% of the current petroleum-fueled P-3. The total cost of LH2 as fuel is currently undetermined. / Ensign, United States Navy

A clear definition of pilot performance beyond manipulative skills remains a challenge. Attempts have been made to annunciate the cognitive and behavioural skill set which comprises this area of performance. Crew resource management (CRM) is one such effort which, while it has done much to identify pilot behaviours, has not translated easily into useable selection and general performance instruments. CRM has not yet identified an umbrella construct which clearly and efficiently organises management of flight aspects of the airline piloting role. Markers that are used by airline check and training personnel in a specific airline to assess suitability for command were identified. Organisational understanding of SA was explored and revealed a more strategic focus than the tactical approach adopted by preceding researchers. In a further study, this strategic focus was investigated through a series of semi-structured interviews with experienced airline Captains. Recurring activity themes were identified and were found to approximate the proposed constructs of self-regulation. This concept was explored and defined in a further study which identified actions which were considered essentials to the functionality of each of these recurring themes. These results were used as the foundation for a novel set of management of flight performance indicators for the organisation within which the research was carried out. Initial trials of an ipsative questionnaire derived from these action statements were carried out as the final study of this research / Doctor of Philosophy (PhD)
