Attitudes to safety and organisational culture in Australian military aviation

Falconer, Boyd Travis, School of Aviation, UNSW January 2006 (has links)
This thesis describes original research that examines the extent to which organisational culture, and psychosocial aspects specifically, relate to individuals??? ???normal??? performance within Australian Defence Force (ADF) aviation. The primary rationale for the research relates to the ???safety record??? of ADF aviation, whereby more than fifty ???peace time??? fatalities have occurred in ADF aviation accidents since 1990 and many of these have links to organisational culture attributes. The secondary rationale relates to a more general perspective: previous research identifies human functioning in military aviation ??? more than any other aviation domain ??? as being dependent upon psychosocial attributes including interpersonal collaboration, communication and coordination. However, the depth to which such qualities impact the safety of a sociotechnical system remains substantially uncharted. This thesis firstly examines both scientific and Australian military literature on organisational behaviour, culture and human factors. Subsequently, it describes the design and implementation of a new 45-item questionnaire ??? the Australian Defence Force Aviation Questionnaire (ADFAQ). More than four hundred ADF aircrew and engineers completed the ADFAQ. The data analysis involved quantitative and qualitative consideration of survey responses and comparisons between numerous demographic criteria. Following this, the thesis describes the design and implementation of an interview study that was designed to both cross-examine key ADFAQ results and explore more deeply other issues that were only superficially identified by the (largely psychometric) composition of the ADFAQ. The research results offer three main contributions to scientific knowledge. These relate to: (1) the efficacy of triangulated and contextualised methodology in building an understanding of organisational culture; (2) the nature of the safety culture concept and its relationship with organisational culture; and (3) rank-based homogeneity of attitudes. This research shows that survey methodologies are not a panacea, but they can illuminate the nature of attitudes to safety and provide empirical guidance for other methods to explore more deeply the cultural roots of such attitudes and associated behaviours.

Optimal Path Planning for Single and Multiple Aircraft Using a Reduced Order Formulation

Twigg, Shannon 09 April 2007 (has links)
High-flying unmanned reconnaissance and surveillance systems are now being used extensively in the United States military. Current development programs are producing demonstrations of next-generation unmanned flight systems that are designed to perform combat missions. Their use in first-strike combat operations will dictate operations in densely cluttered environments that include unknown obstacles and threats, and will require the use of terrain for masking. The demand for autonomy of operations in such environments dictates the need for advanced trajectory optimization capabilities. In addition, the ability to coordinate the movements of more than one aircraft in the same area is an emerging challenge. This thesis examines using an analytical reduced order formulation for trajectory generation for minimum time and terrain masking cases. First, pseudo-3D constant velocity equations of motion are used for path planning for a single vehicle. In addition, the inclusion of winds, moving targets and moving threats is considered. Then, this formulation is increased to using 3D equations of motion, both with a constant velocity and with a simplified varying velocity model. Next, the constant velocity equations of motion are expanded to include the simultaneous path planning of an unspecified number of vehicles, for both aircraft avoidance situations and formation flight cases.

A high speed network architecture for real time testing of an embedded computer system

Woelfer, Karl Alan, 1952- January 1989 (has links)
The Embedded Computer System Support Improvement Program, or ESIP, was begun by the U.S. Air Force in 1983 to find new cost effective ways of integrating, testing and maintaining the computers embedded in military airborne, spaceborne, and ground electronic systems. A major initiative of this program is the Extendable Integration Support Environment (EISE). The EISE project involves design and development of a high speed network-based hardware and software integration and test environment. The ongoing work is being done jointly by U.S. Air Force civilian engineers at McClellan Air Force Base and TRW in Sacramento, California, in support of embedded avionics computers in the A-10 aircraft. The prototype design will be used to test and integrate various other aircraft and space systems. The author was the EISE project lead system engineer from July 1986 through January 1988.
