Full textAbstract:
In this thesis, risk management methods are investigated in order to integrate risk management practices into the Turkish Aerospace industry. The research presents the sequence of risk management processes as identification of risk, analysis of risk, risk planning etc. Risk analysis methods named as Risk Ranking and Analytical Hierarchy Process (AHP) are investigated in order to improve reliability and safety of the systems or processes in the aerospace industry. The main aim of using risk ranking and AHP together is to translate the knowledge in the Turkish Aviation Industry to a tangible form with a quantitative approach and to prepare a basis for probabilistic risk analysis. Instrument Landing System (ILS) has been considered only in order to facilitate a demonstration how risk management can be done in this context. This study investigates and seeks to create awareness for risk management practices within Turkish Aviation industry.

Full textAbstract:
In the aviation industry, purchasing departments spend approximately 80% of revenues on procurement. Additionally, 62% of companies experience unforeseen expenses or hidden costs in the procurement process. Grounded in a conceptual framework of activity-based costing, the purpose of this case study was to explore strategies used by 5 upper-level supply chain management leaders at a maintenance repair and overhaul company in the aviation industry in the Southeastern United States to accurately forecast procurement costs. Data collection included 5 semistructured interviews, company documents, and annual reports. Through thematic analysis, the major themes that emerged from the data analysis were accuracy, competitive advantage, improved corporate performance, and improved total cost analysis. The findings may contribute to social change in the Southeastern region of the United States. The aviation industry is experiencing competition from low-cost countries and the economy of the region and hundreds of families and educational institutions depend on the success of the companies in the region for sustainability.

Full textAbstract:
L’industrie aéronautique poursuit depuis de nombreuses années l’objectif d’un niveau optimal de sécurité dans le cadre du transport aérien. En ce qui concerne l’aviation militaire, plus exactement tactique, cette priorité se double d’une recherche de performance de plus en plus élevée et polymorphe. Ce qui caractérise ce type d’aviation, c’est le rapport entre la performance poursuivie et les risques acceptés. Il dépend essentiellement du contexte et des enjeux des missions à réaliser.L’approche facteur humain constitue un levier d’action majeur pour permettre la réalisation de cet enjeu. Ainsi, dans le cadre contraint de l’aéronautique, la conception et la mise au point d’outils permettant d’assister la cognition des équipages demeure une perspective d’avenir même si la formation des pilotes devient également un enjeu majeur pour les prochaines années. Dans ce contexte, la gestion des ressources cognitives, et plus particulièrement les stratégies spécifiques de gestion mises en place par les pilotes, sont centrales au processus de prise de décision sous contraintes.Dans une démarche de recherche et d’ingénierie en cognitique, nous avons entrepris une étude impliquant des pilotes et permettant la compréhension de ces mécanismes ainsi que la production de recommandations pour la conception d’outil d’aide à la gestion de leurs ressources cognitives. A partir de l’analyse du retour d’expériences, et sur la base des résultats d’une approche expérimentale préliminaire, nous avons construit un protocole pour mettre en évidence les stratégies mises en place par les pilotes, dans le cadre d’une activité réelle, lors de la descente et de l’approche finale sur l’aéroport de Clermont-Ferrand avec une panne critique. Les résultats expérimentaux conciliés à nos hypothèses de compréhension sur la gestion des ressources cognitives et les stratégies de gestion, achèvent notre analyse et nos recommandations pour un outil d’aide à la gestion des ressources des pilotes.14 équipages d’Airbus A400M de l’armée de l’air ont participés à cette évaluation en simulateurThe aviation industry has for many years pursued the objective of an optimum level of safetyin the air transport sector. With regard to military aviation, more precisely tactical, thispriority is coupled with an increasingly high and polymorphic search for performance. Whatcharacterize this type of aviation is the relationship between the performance pursued and theaccepted risks. It depends essentially on the context and the stakes of the missions to becarried out.The human factor approach is a major leverage for achieving this challenge. Thus, within theconstrained domain of aeronautics, the design and development of tools to assist crewcognition remains a prospect for the future, even if pilot training also becomes a majorchallenge for the coming years. In this context, the management of cognitive resources, and inparticular the specific management strategies put in place by the pilots, are central to thedecision-making process under constraints.In a research and engineering approach in cognition, we undertook a study involving pilotsand allowing the understanding of these mechanisms as well as the production ofrecommendations for the design of tools to help manage their cognitive resources. On thebasis of the analysis of feedback, and results of a preliminary experimental approach, we havebuilt a protocol to highlight the strategies implemented by the pilots in the context of anactivity during the descent and the final approach on the Clermont-Ferrand airport with acritical breakdown. The experimental results reconciled with our understanding hypotheseson the management of cognitive resources and management strategies, complete our analysisand recommendations for a tool to help manage the resources of the pilots

Fleming, Elizabeth Scott. "Developing a training program for the traffic alert and collision avoidance system in context." Thesis, Georgia Institute of Technology, 2013. http://hdl.handle.net/1853/47578.
Full textAbstract:
The Traffic alert and Collision Avoidance System (TCAS) is an aircraft collision avoidance system designed to prevent mid-air collisions. During an advisory, danger is imminent, and TCAS is assumed to have better, more up-to-date information than the ground operated air traffic control (ATC) facility. Following a TCAS RA is generally the safe course of action during an advisory. However, pilot compliance with RAs is surprisingly low. Results from a TCAS monitoring study show pilots are not complying with many TCAS advisories. As revealed by pilot-submitted Aviation Safety Reporting System (ASRS) reports, this noncompliance could be attributed, in part, to pilot confusion to TCAS operation as well as misunderstandings of the appropriate response to a TCAS issued advisory.
This thesis details the development and evaluation of a TCAS training program intended to improve pilots' understanding of TCAS use for collision avoidance in a range of traffic situations. The training program integrated Demonstration Based and Event Based Training techniques. Its efficacy was analyzed in an integrated ATC-cockpit simulator study in which eighteen commercial airline pilots were asked to complete the TCAS training program and afterwards experienced twelve experimental traffic events. The trained pilots' performance was compared to the performance of 16 baseline pilots who did not receive the modified training.
Overall, the training program did have a significant impact on the pilots' behavior and response to TCAS advisories. The measure Time Pilots First Achieved Compliance decreased with the trained pilots, as did the measure Autopilot Disconnect Time After RA Initiation. Trained pilots exhibited less aggressive performance in response to a TCAS RA (including a decrease in the measures Altitude Deviation Over Duration Of RA, Average Vertical Rate Difference, Maximum Vertical Rate Difference, and Maximum Vertical Rate). The measure Percent Compliance did not significantly vary between trained and baseline pilots, although trained pilots had a more consistent response in the traffic event with conflicting ATC guidance. Finally, on the post-experiment questionnaires, pilots commented on their increase in understanding of TCAS as well as an increase in their trust in the advisory system.
Results of this research inform TCAS training objectives provided by the FAA as well as the design of TCAS training. Additionally, conclusions extend more broadly to improved training techniques for other similar complex, time-critical situations.

Full textAbstract:
Risk management is considered to be an application of general concepts in scientific management of a particular problem of exposure to risk of loss. It is concerned with identifying objectives, analysing the data regarding the nature of the problem, evaluating the pure risks deriving from the nature of the business and choosing or finding the most suitable method or methods of handling these risks; aiming to control them and their effects as well as minimizing the cost. The field of aviation has grown very quickly and developed faster in the last few years to reach the present level of operation and technology by introducing more advanced and higher capacity airliners. Therefore, aviation risks and their financial impact exhibit a number of distinguishing characteristics that raise problems for traditional risk management and insurance technique in dealing with such risks. The study reviews, analyses and classifies aviation risks and their characteristics as well as the major hazards involved in aircraft and their operation. The research undertakes to review the international conventions and agreements affecting air transportation and the limits of liabilities affecting those who operate airlines internationally in respect of death, injury or damage caused to passengers, baggage, cargo and third parties as well as safety and security of aircraft in the air and on the ground. It also studies and analyses the international jet airliner fleet, their accidents and their causes to provide a basis of choosing suitable risk levels in managing these risks.

Full textAbstract:
Our aim is to investigate and evaluate the efficiency of crisis management in European aviation, and to recommend enhancements. To fulfill this, we mapped the current crisis management plans and created a fictive scenario where a cyber-attack shut down the power at five of the major airports in Europe. Air traffic in Europe was reconstructed to a chosen day; the 16th of September 2013, and the reconstructed traffic situation was used in the scenario. We also created a model, for the purpose of showing the effect of a cut in time for the steps in the crisis management plan may have on the traffic waiting to depart at the closed airports. When using these means, we could implement the crisis management plans on the fictive scenario and make changes to the plans for a new implementation. The existing crisis management plans were compared to the modified plans made by us, and it was found that usage of a common platform for the different stakeholders involved in the crisis could improve the efficiency of the crisis management.

Dlima, Kendrick M. "Conceptual Design of a South Pole Carrier Pigeon UAV." DigitalCommons@CalPoly, 2020. https://digitalcommons.calpoly.edu/theses/2145.
Full textAbstract:
Currently, the South Pole has a large data problem. It is estimated that 1.2 TB of data is being produced every day, but less than 500 GB of that data is being uploaded via aging satellites to researchers in other parts of the world. This requires those at the South Pole to analyze the data and carefully select the parts to send, possibly missing out on vital scientific information. The South Pole Carrier Pigeon will look to bridge this data gap.
The Carrier Pigeon will be a small unmanned aerial vehicle that will carry a 30 TB solid-state hard drive from the South Pole to various destinations in the Southern Hemisphere, but it has been designed to y to Christchurch, New Zealand. This 87 lb. UAV will be able to y 3,650 nmi. up to 25,000 ft., using a 5.7 hp. engine. It will feature an de-icing system on the leading edge of its 8 ft. span wing to allow it to y through cold, moist climates. It will have a 39 in. long fuselage with a tail boom of 33 in.
The aircraft has been designed to be made out of composites, thus reducing both the weight of the aircraft as well as its drag. It has been designed to come apart in order to be shipped successfully to the South Pole. There, it will be assembled and launched via a custom pneumatic launcher. It will y autonomously to 15,000 ft. and cruise climb throughout the flight to 25,000 ft., before descending to its destination. There, it will be caught by a net restraint system, where the hard drive will be extracted. The Carrier Pigeon is truly a unique vehicle for its size, range, and robustness.

Full textAbstract:
The thesis in the first part examines the notion of risk and describes the process of risk management with emphasis on the identification of emerging threats to civil aviation and on the adoption of new risk handling techniques.In the second part, the role of law into the airlines' management regime is examined especially in the light of two prima facie conflicting trends: liberalization of market access and increased State involvement in war risk, safety and security issues. Furthermore, the contractual and tortious/delictual exposures of airlines are being scrutinized and the ways to handle them are being analyzed.
The main objectives are (i) to demonstrate that risk management is not restricted to insurance, but involves a number of techniques and procedures that have the potential not only to minimize risk but also to turn risk into opportunity and value and (ii) to identify the role of law as a management tool in the oncoming liberalized aviation environment.

Approved for public release; distribution is unlimitedThis thesis examines the current policy and procedures used to manage naval aviation configuration control. It recommends that the Navy consult with SABRE Decision Technologies, or a company with a similar background, to re- engineer the process for approving configuration changes and create an information technology system to manage the process. During this study, I have identified two major challenges to naval aviation configuration policy. They are: (1) the process used to review and approve Engineering Change Proposals (ECPs) is too complex and has too many stakeholders and (2) the current method for management of approved configuration changes is man-hour intensive, has potential for administrative error, and requires physical inspection to positively verify aircraft and equipment configurations. Finally, this study presents the theory that there are many common requirements between naval aviation maintenance and commercial airline maintenance. We should take advantage of the experience and technological innovations of industry and use them to make our configuration policy, and our entire maintenance effort, more effective for the users in the fleet

Full textAbstract:
With the expected growth in air transportation, one can experience an increase in the number of incidents and accidents, despite constant or even slightly declining accident and incident rates. Therefore, it is necessary to examine how to improve aviation safety even further. Several studies and statistical analyses show that most accidents result from human and organizational factors, encompassing pilot error, training deficiencies, management error, an ineffective organizational structure, and a lack of safety culture. In these regards, Aviation Safety Management Systems are widely acknowledged as a managerial tool whereby risks and hazards can be managed to avoid the occurrence of an accident. A Safety Management System is an integrated set of process, beliefs and procedures for identifying, classifying, monitoring and managing the hazard and risk for the safety of the organization. It must include, at least, a safety policy which express commitment from upper management; an effective safety reporting system; a hazard and risk analysis; procedures to determine actions to reduce or eliminate risks; training process which keeps staff trained, informed and upgraded about safety issues; and an evaluating process to ensure that the safety management system remains effective and relevant to the organization. The objective of this dissertation is to define the basic elements (processes) of a Safety Management System, describing its characteristics and the way it can be implemented, and to propose a Safety Management Process to be implemented at an aeronautical industry. It also can be implemented in any other kind of industry that looks forward to improve safety and reduce the number of accidents and incidents. Nonetheless, the process must be customized to meet the characteristics of this industry.

(cont.) payoff IT investments. When the North American Aerospace Industry invests less than any other industry in the high risk investments, its foreign counterpart invests more than any other industry. The second major finding is that the governance mechanisms in place are similar in the two Aerospace Industry segments, contrary to the IT Portfolios. IT decisions are made usually by IT executives or business executives, based on the information provided by Chief level executives and at least one other business group. Finally, the third major finding is that the Aerospace Industry gets above average returns from IT by being good at IT Business Planning, Top Management involvement and User Satisfaction. However, a major effort needs to be placed on improving user satisfaction as it is not always properly managed and hinders returns from IT. The lack of extensive communication also hinders the returns from IT by not guarantying top management involvement and awareness of the IT governance mechanisms.
This thesis originated by a need for the Lean Aerospace Industry to study in the Aerospace Industry what seems to be a troublesome domain for many other industries: Information Technologies (IT). Beforehand, there were two ways to do so: study how aerospace companies implement major systems like Enterprise Resource Planning (ERP) or Product Data Management (PDM). After a few short case studies, it seemed companies were puzzled by the true extent and the pervasiveness of IT. Therefore, we chose to not look at IT "locally" but try to understand the bigger picture. This thesis is largely based on the pioneering work done by Peter Weill and the Center for Information Systems Research of the MIT Sloan School of Management on IT Portfolio and IT governance. It rationalizes IT by setting it as a portfolio, just like financial investments. Balancing the IT portfolio will ensure anticipated alignment with the corporate strategies. However, the elaboration of proper IT governance mechanisms is necessary to ensure value and return from IT. Defining the governance is "specifying the decision rights and accountability framework to encourage desirable behavior on the use of IT". We therefore applied the IT Portfolio and IT governance frameworks defined by Peter Weill to the Aerospace Industry through the analysis of surveys available in Appendix D. We were able to get data from ten different companies spread out across the world. This allowed us to examine several IT profiles, and to make several significant findings, among which three are of major importance and are described below. The first major finding is that the North American IT portfolio is risk-averse, while the aggregated rest of the world is prone to invest heavily in high risk/high

Over the last decade the aerospace industry has seen a shift in traditional architectures of an aircraft. The desire for aircraft to be lighter, more efficient, quieter, faster, and cheaper has driven trends across the industry. These trends look for ways to accomplish what many other industries such as automotive have done which is a complete transformation of the "normal." The shift has created an advanced architecture for aircraft and therefore requires a new view on certification. The traditional approach for certification is pretty straightforward since majority of aircraft have been the same over several years with minor changes in sub level aircraft systems. Aircraft manufacturers in combination with suppliers develop concepts for new or improved aircraft, requirements are outlined and implemented based on aviation authority regulations, and eventually the aircraft receives a certificate declaring the safety of the aircraft design and production. In fairness, the traditional standard approach to aircraft certification has worked. Aircraft are safer than ever and data shows a sharp decline in aviation accidents over the years. However, with changes in technology what use to be the "normal" architecture is changing significantly and the desire for the industry to be more agile both play a role in the need to view certification slightly different. The main objective of certification has been, is, and will always be safety. This thesis proposes a framework on how to approach certification of new technologies. Perhaps the two most important elements in the framework are the proposal of a threshold utilizing the technology infusion effort equation to gage the significance of a change in architecture and the proactive safety analysis utilizing a new kind of technique called STPA. The framework is developed based on an in-depth outline of the traditional certification process and a review of the historical development of safety regulations. Two parts of the proposed framework are then applied and analyzed based on the more electric aircraft concept.

Find full textAbstract:
The work described in this final dissertation addresses the use of virtual reality in flight simulation. The attention has been focused on several aspects which should be considered when dealing with this topic, such: as the certification requirements issued by the European Union Aviation Safety Agency (EASA); the systems and different components that made up a flight simulator; the limits in
training efficiency and effectiveness with traditional flight simulators; the integration of virtual reality in flight simulation; the possible strategies to develop a virtual reality-based simulator; and finally the results that could be achieved in
terms of realism, usability, implementation, compliance with regulations with simulation in virtual reality.
The simulation is fluid and the use of advanced scenarios does not affect the simulation. Thanks to the fact that open-source software has been used for the simulator, several customizations can be implemented to obtain different environments . It could be possible to simulate helicopters, commercial aircraft, or gliders easily by simply changing the flight commands with specific
devices: the straightforward advantage is that the cockpit and the external environment can be changed in a click because it’s all virtual. Moreover, the commands should be realistic in terms of grip and touch sensation, but their aesthetic features are not important because the pilots see the virtual commands during the simulation, and not the real ones.
Future developments include the implementation of codes to simulate without the user intervention and setting phase that is required now. Moreover, a testing phase with pilots could provide the developers with useful suggestions to increase the usability of the tool. The improvement of the simulation could lead up to its certification provided that the requirements by EASA that currently are not satisfied are addressed.

Distinctive technology and customer / supplier relationships are currently the primary sources of competitive advantage in the Aerospace industry. Modular Open System Architecture (MOSA) requirements represent a significant disruption to this mode of competition. The United States Department of Defense intends to accelerate the rate of aerospace innovation and inject additional competitiveness into the procurement process through the modularization of its products and effective intellectual property management. This combination of architectural disruption and new customer capabilities has the potential to reduce the industry's opportunity to capture value from innovative technologies or a position as first supplier. Historical examples such as Polaroid and IBM demonstrate the organizational paralysis that often results from disruptions in product architecture. The competitive formula becomes ingrained in the processes, resources, and culture of mature companies and is no longer explicit knowledge, which limits the company's ability to develop the capabilities required to compete in its new environment. Competing in a MOSA environment will require the development of new organizational capabilities such as rapid experimentation, fighting standards wars, and protecting system-level knowledge. Defining the disruptive threat and the foundations of current core competencies will enable firms to develop the organizational capabilities essential for this shift in competitive context.
(cont.) The author will present several historical examples of architectural disruption, a framework for evaluating the disruptive change, and an identification of organizational anchors that may hinder a particular competitor's ability to respond to MOSA. The goal of the thesis is to start a dialogue within an identified incumbent with in hopes of beginning the organizational transformation required to effectively compete in this new era.

This paper introduces multiple methods to set and optimize inventory levels. These methods are then classified based on the complexity involved to implement them. As an organization develops a deeper understanding of inventory, it becomes more mature and can apply more complex methods. This sequencing of methods is defined as a three phase maturity model. First, a foundational level of maturity is defined, which quantifies inventory levels based on future demand and business requirements. Second, a transitional level of maturity defines safety stock positioning in a single-echelon supply chain. Finally, the maturity model concludes with an optimal level of maturity that is based on principles of multi-echelon inventory optimization: safety stock at multiple positions of a supply chain. The setting for this paper was the Aerospace industry. Honeywell Aerospace is in the middle of a 3-year effort to re-engineer Sales, Inventory and Operations Planning (SIOP) systems. At the same time, Honeywell Aerospace is standardizing on a uniform implementation of an ERP system. Through SIOP, standard inventory and planning practices aided by the uniform ERP backbone and a strategic inventory program executive management hopes to reduce what is seen as a disproportionate contribution of inventory to Honeywell International.

Full textAbstract:
Ninety-five percent of all aviation businesses are small businesses; from 2009-2012, small aviation business operations decreased by 10.2% and resulted in a loss of $4.4 billion in revenue. The purpose for this multiunit case study was to explore what strategies small aviation businesses leaders used to reduce or control operating expenses for profitability. The sample comprised 3 small aviation businesses located in Middle Tennessee. The conceptual framework for this study built upon systems theory and sustainability theory. The data were collected through semistructured interviews and company documents. Member checking was completed to strengthen creditability and trustworthiness. Based on the methodological triangulation of the data sources collected, 5 emergent themes were identified after completing the 5 stages of data analysis: buying or purchasing power, being customer focused, having the right employees, having the right equipment, and leadership. When small aviation business owners incorporate these themes into their business model, they may increase the prosperity of their companies, the employees, their families, the surrounding communities, and the local economy. The findings from the study may contribute to social change by providing insights and strategies for small aviation business leaders in reducing operating costs for profitability. The data from this study may contribute to the prosperity of the small aviation business leaders, their employees, their families, the surrounding community, the local airport, and the local economy. By reducing operating expenses, small aviation business leaders will have more money to invest in the local community and the economy.

Full textAbstract:
The CubeSat standard originated in 1999. It was a joint development led by Dr. Jordi Puig-Suari of California State Polytechnic University San Luis Obispo and Professor Robert Twiggs of Stanford University. The engineering challenges that have come from this picosatellite class have created incredible educational opportunities for engineering students throughout the world. Since the challenges of engineering a CubeSat abound the designers are always looking at novel and even revolutionary solutions to each one. One of those opportunities is in thermal subsystem design, implementation and characterization. A potential solution for CubeSats is adaptive component usage.
This thesis is the written catalogue of my study of adaptive component utilization to solve the thermal management problem inherent in picosatellites. Inside the limited design space of a picosatellite’s electrical, mechanical and software subsystems active spacecraft thermal control often is a necessary forfeiture. This does not preclude CubeSat teams from addressing the thermal aspect of spacecraft design. To the contrary it forces them down a different route to ensuring the spacecraft is verified to meet appropriate environmental constraints. Most CubeSat teams, Cal Poly included, use punishing qualification testing, robust system design and a restricted spacecraft operational lifespan ensure their system will operate through all of the environments it will encounter during launch, separation, spacecraft activation and on until the end of operations.
The testing, engineering and modeling I performed were to answer the hypothesis, can a standard* 1-U CubeSat utilize existing hardware and software to improve its thermal condition and operational lifetime?
This hypothesis assumes thermal control or situational improvement would have to be gained without the addition of thermal control surfaces, active heaters, heat pipes or louvers and no additional flight software. Ground control software and operation alterations were explicitly not included in these assumptions.
The thesis began with defining the many unknowns that existed in the material properties. This required: research into the methods required, specialized measurement hardware to be obtained and set-up, controlled measurements to be taken and thorough testing procedures to be developed. Once the unknowns were better defined the thesis required a detailed satellite thermal analysis by multiple methods along with both thermal vacuum chamber simulation trials and finally on-orbit testing.
Based on the research, modeling and testing performed and results obtained through this study, yes, a standard* 1-U CubeSat utilizing existing hardware and software can improve its thermal condition and operational lifetime. As is shown in Section 3.0 and discussed in detail in Section 4.0, utilizing only the onboard electronics and existing flight software the orbital temperature delta that components are experiencing can be reduced by up to 35.8%. Further analyses in section 4.0 use the temperature data to show that by lowering the temperature deltas the satellite does in fact have the capability to both improve its lifetime and certain key subsystem performance parameters.

Aviation has used petroleum-derived fuels for over 100 years. With the rapidly rising price of oil and concerns about supply, the military and the commercial airlines are fostering the development of an alternative aviation fuel industry. In the U.S., coal, oil shale and biomass offer great promise as alternatives to petroleum for the production of aviation fuels. For the alternative fuel to be viable, the fuel must be price competitive, offer environmental benefits compared to petroleum, and must be qualified and certified for use in aviation. This thesis explores the barriers and risks associated with the technology adoption life cycle for alternative aviation fuels as viewed through the lenses of the technology developer, the early adopter, the early majority user, and the financial community. The challenges related to crossing the "Valley of Death" between technology development and deployment, and bridging the "Chasm" between the early adopters and the early majority of users are explored and a series of evaluation frameworks, tools, models, and recommendations are presented. The suggestions and recommendations provide potential actions that the military and the civil aviation sector could implement to reduce the risks and barriers for an alternative aviation fuel industry to commence and be sustainable both financially and environmentally.

Full textAbstract:
This thesis expands current understanding of the process through which new management concepts diffuse in organizational fields. The thesis examines how environmental management concepts have diffused in civil aviation, an industry which has evolved from a praised icon of globalization to a targeted symbol of climate change over the last decade.In the first phase of the study, qualitative data were gathered through participation at industry conferences and events, supplemented by 35 semi-structured interviews with informants representing diverse actors in the field of civil aviation. This fieldwork was used to generate theory on the process through which the concept of sustainability is being interpreted and adopted within this industry. The second phase of the study is a systematic analysis of archival data from a trade publication over the time period 2000-2008. Structured content analysis methods were employed to track evolution in the framing of environmental management issues at the level of the industry. The study expands current understandings of diffusion by (a) describing a process of naturalization, through which a new concept is being interpreted and an industry-level ethos is being reaffirmed; and (b) specifying some conditions leading to divergent diffusion, characterized as a situation in which multiple understandings of a management concept continue to coexist throughout diffusion. The study thus contributes to current institutional theories on management concept diffusion through a process perspective describing the interpretive mechanisms underlying diffusion and through conceptualization of the conditions and attributes of divergent diffusion.Cette thèse contribue à une meilleure compréhension du processus par lequel les nouveaux concepts de gestion se propagent dans les champs organisationnels. La thèse examine la diffusion des concepts de management environnemental au sein de l'aviation civile, une industrie qui était l'icône de la mondialisation il y a une dizaine d'années, et qui est devenue la cible d'activistes et un symbole du changement climatique aujourd'hui. Dans la première phase de l'étude, des données qualitatives ont été recueillies par une observation participante dans des conférences et des évènements organisés par l'industrie, puis par 35 entrevues individuelles avec des informateurs représentant divers acteurs stratégiques dans le champ de l'aviation civile. Ce travail de terrain a été utilisé pour générer une théorie du processus d'interprétation et d'adoption du concept de développement durable au sein de cette industrie. La seconde phase de l'étude est une analyse systématique de données d'archives provenant d'un journal spécialisé, sur la période 2000-2008. Des méthodes d'analyse de contenu ont été utilisées pour retracer l'évolution des termes employés pour décrire et « cadrer » les problèmes environnementaux au niveau de l'industrie. L'étude contribue aux théories actuelles de diffusion, (a) en décrivant le processus de naturalisation, par lequel le nouveau concept est interprété, et un ethos de l'industrie est réaffirmé; et (b) en spécifiant quelles conditions mènent à une diffusion divergente, caractérisée par une situation dans laquelle de multiples compréhensions d'un même concept de gestion continuent à coexister tout au long de sa diffusion. L'étude contribue ainsi aux théories institutionnelles sur la diffusion des concepts de gestion en proposant une perspective centrée sur le processus, décrivant les mécanismes interprétatifs qui sous-tendent la diffusion, et en conceptualisant les conditions et les attributs d'une diffusion divergente.

It is broadly recognized in the aerospace industry, as well as many others, that organizations which effectively execute development projects to meet desired cost, schedule, and performance targets for their customers produce higher levels of customer satisfaction and also a significant source of competitive advantage. Continually meeting the needs of the customer through effective project execution allows a company to become a preferred supplier favored in source selection for follow-on contracts and new development projects necessary for business growth. This research effort examines one aerospace company, which has multiple, diverse development projects on-going at any one time across several business units. The motivation for this thesis is to explore the product/system development capacity of the enterprise by analyzing the historical program performance of major projects, understanding the level of problem projects or fire fighting within the project pipeline, and the perceived causes of poor project performance. In addition, system dynamics models are developed to analyze the dynamics associated with project planning and resource planning strategies for both multi-project and single project scenarios. This analysis provides insight into the potential for project pipeline "tipping" and the effects of various project management and resource planning strategies in an aerospace product/system development context. Such analysis is believed to provide greater insight and opportunity to improve the product/system development performance for the enterprise.

The emergence of composite material application in major commercial aircraft design, represented by the Boeing 787 and Airbus A350-XWB, signals a new era in the aerospace industry. The high stiffness to weight ratio of continuous fiber composites (CFC) makes CFCs one of the most important materials to be introduced in modern aircraft industry. In addition to inherent strength (per given weight) of CFCs, they also offer the unusual opportunity to design the structure and material concurrently. The directional properties (and the ability to change these properties through the design process) of composite materials can be used in aeroelastically tailored wings, the fuselage and other critical areas. Due to the longer lifecycle (25-30 years) of a commercial airliner and the tools and processes developed for the airplane of previous product development cycles, new technology often ends up being deployed less effectively because of the mismatch in the technical potential (what can be done) vs. design tools and processes (what was done before). Tools and processes need to be current to take advantage of latest technology, and this thesis will describe one possible approach in primary composite structural design area using integrated structural analysis

Full textAbstract:
This study is about talent management, focusing on a case study of the initiatives undertaken by the Directorate of Civil Aviation (DCA) of Namibia over the period 2008 to 2014 in securing talent for aviation safety. The International Civil Aviation Organisation (ICAO) regularly assesses the extent to which member states comply with their safety oversight responsibilities. According to a 1996 report by the ICAO, under the auspices of its Universal Safety Oversight and Security Audit Programme (USOSAP), Namibia’s safety oversight was found to be weak, as indicative of the State’s inability to guarantee the safety of aircraft operations within the national airspace (ICAO, 1996). One of the significant audit findings was the critical shortage of qualified professionals at the Directorate Civil Aviation (DCA) to effectively perform the State’s regulatory and oversight function as contained in the Chicago Convention of 1944. The shortage of qualified professionals resulted in Namibia being unable to respond to its obligations and responsibilities under the Chicago Convention and Namibia’s subsequent blacklisting by the ICAO Audit Result Review Board (ARRB). Consequently, a corrective action plan was undertaken. This study examines one aspect of this plan, namely the initiatives that were undertaken to secure the talent required for aviation safety posts. The aim of the research is, from the perspective of talent management, to analyse the corrective action plan of the Directorate of Civil Aviation (DCA), as a process of securing talent for strategic positions in aviation safety in Namibia. This initiative was analysed from the perspective of the fourth stream of talent management, which emphasises securing talent for strategic positions (Collings and Mellahi, 2009; Huselid & Becker, 2011). Taking into account the fact that Namibia was a racially and culturally divided society until about 25 years ago, the study also deals with issues of diversity management as they impacted upon the talent management of the civil aviation industry nationally. Furthermore, the study is located against the background of the Bantu Education System that was provided by the apartheid South African government to Namibians before independence in 1990. The research design of this study involved conducting a case study that followed a deductive approach. Data were collected using multiple methods and sources such as documentation, interviews and archival records. Content analysis was used in the analysis of collected data. The findings of the study showed the talent management strategies that were adopted in managing strategic positions, the challenges encountered and the impact of the programme. The findings were initially discussed from the perspective of stream four of talent management, with its focus on strategic positions in organisations. Some of the findings of the study were in line with this approach to talent management, but certain challenges that were encountered in carrying out the talent management programme could not be addressed from this perspective, thereby exposing the limits of this approach to talent management in an emerging economy like Namibia. Consequently, a proposed model of sustainable talent management for the DCA was developed. From the perspective of this model of sustainable talent management, recommendations were made for practice and further research.

Many aerospace companies are turning to additive manufacturing solutions to stream-line current production processes and open opportunities for on-demand producibility. While many OEMs are drawn to the appeal of the benefits that additive manufacturing brings, they are beginning to understand the difficulties in what it takes to realize those benefits. This paper analyzes additive manufacturing from an industry perspective down to a company perspective to develop a deeper understanding of the practical use cases as well as the various challenges a company faces should they choose to enter this market. This study begins with market research on the additive manufacturing and aerospace industry before honing in on a several use-case parts from rotary aircraft. Selection criterion were created and applied to analyze the value that additive manufacturing would bring in comparison to that of conventional methods, ultimately determining its feasibility for additive manufacturing.
This study applied the selection criterion to various parts of differing functions among the aircraft, resulting in a group of candidate parts. An evaluation method was created and applied to provide an objective assessment on the candidate parts. Initial insights show that additive manufacturing favor casted parts with features that can be optimized to increase performance and reduce costs and weight. In addition, aerospace has the best product mix of low volume parts that are advantageous to the economies of scale for additive manufacturing. Additionally, this study analyzes a company's organization and previous additive manufacturing efforts to propose ways to approach future development. Venturing through the various road maps that lead to the final goal of certification and addressing organizational barriers generate momentum for continuous development.
These road maps, selection criterion, and evaluation method can be applied through many applications within the general aerospace industry.

Full textAbstract:
The investigation and modelling of aviation accident causation is dominated by linear models. Aviation is, however, a complex system and as such suffers from being artificially manipulated into non-complex models and methods. This thesis addresses this issue by developing a new approach to investigating aviation accident causation through information networks. These networks centralise communication and the flow of information as key indicators of a system‟s health and risk. The holistic approach focuses on the system itself rather than any individual event. The activity and communication of constituent elements, both human and non-human agents, within that system is identified and highlights areas of system failure. The model offers many potential developments and some key areas are studied in this research. Through the centralisation of barriers and information nodes the method can be applied to almost any situation. The application of Bayesian mathematics to historical data populations provides scope for studying error migration and barrier manipulation. The thesis also provides application of these predictions to a flight simulator study in an attempt of validation. Beyond this the thesis also discusses the applicability of the approach to industry. Through working with a legacy airline the methods discussed are used as the basis for a new and forward-thinking safety management system. This holistic approach focuses on the system environment, the activity that takes place within it, the strategies used to conduct this activity, the way in which the constituent parts of the system (both human and non-human) interact and the behaviour required. Each stage of this thesis identifies and expands upon the potential of the information network approach maintaining firm focus on the overall health of a system. It is contended that through the further development and application of this approach, understanding of aviation risk can be improved.

Full textAbstract:
Structural change in organisations is stressful for staff and the managers who must implement it. Most change programs use employee communication techniques to support change directions set by senior executive decision makers-dominant coalitions.
This research used a single case study to explain the context and management discourses of a major re-structure of an Australian Federal Government agency, the former Civil Aviation Authority (CAA), during the early 1990s. A content analysis examined the use of keywords in management discourses that argued the need for change. The keywords represented the two major change discourses: micro-economic reform and aviation safety regulation. A critical discourse analysis investigated the dominant coalition's discourse strategies to justify change. Content and process communication theories, and the role of framing in organisational change, were used to explain how employees may have reacted to change directions.
The research found that change directions were framed as an economic imperative that clashed with a traditional organisational culture that emphasised the primacy of aviation safety. It found that mixed messages by the two principal members of the dominant coalition who drove change exacerbated the clash.
The results suggest a need for further analysis of management discourses used to inform employees about structural change, especially in organisations that have legislative responsibilities. Further analysis of change messages framed by dominant coalitions could lead to a deeper understanding ofhow they affect employees and the change process.

Full textAbstract:
Air transport, in 2018, was the means of transport chosen by 8.8 billion people around the world. This is a sector that expected continued passenger growth in the following years, but due to the current effects of the Covid-19 pandemic has
reduced its projections. However, the sector is expected to return to normal after the passage of the pandemic. Aviation was responsible, for combustion alone, for 2% of CO2 emissions and 12% of total greenhouse gas (GHG) emissions within the transport sector worldwide. Nevertheless, there were other GHG emissions derived from this activity, such as, among others,
the emissions generated by the catering service and its waste management. In 2018, it was estimated that 5.7 million tons of waste were generated, which had to be managed. The management of this waste in the European Union is conditioned by the European regulation CE 1069/2009. This regulation limits the management of organic waste of animal origin generated on flights from countries outside the European Union (the so called “Category 1”) to landfilling or incineration.
Both the introduction to this thesis and the first scientific paper describe this situation in depth, as well as the LIFE Zero Cabin Waste project, in which they have been developed. Characterizing waste streams is essential to find the complex solutions that their classification and treatment require. It is especially relevant in the aviation sector, in which the different types of waste are collected together and most of them end up in landfills, generating GHG emissions, and contributing to the current climate crisis. It is expected that, from 2021, Directive 2019/904 will enter into force and will prohibit certain singleuse plastics that are currently very present in aviation menus. The most comprehensive study to date of characterizations of
the waste generated during 145 flights of different origins and characteristics has been carried out during this thesis, allowing the major fractions to be found and detecting possible improvements to reduce them. It has been verified that the
organic fraction is the biggest one (33%), and that another very important fraction includes the different elements and packaging that we find in the menus. To identify the origin of the most relevant impacts and to find solutions to the different problems encountered, Life Cycle Assessment (LCA) methodology is recommended, allowing to evaluate from cradle to grave, where, and because of what, the most relevant environmental impacts occur. The application of LCA evaluating the 19 elements and packaging that includes an average tourist menu, many of them made of single-use plastic, and reusable
ones made of heavier materials, has led to identify those that contribute the most to GHG emissions (plastic tray 41.4% and steel cutlery set 14.4%) and has demonstrated that, contrary to expectations, GHG emissions will increase with the
introduction of this new Directive.
Once collected separately and classified by fractions, the waste can be treated in different ways, this sequence of processes being the waste management system. Problematic points of the current management system have been identified, and it has been demonstrated that some management changes - which will require a regulatory change in the EU that includes
separate collection at source, the recovery of organic matter, and the increase in recycled materials - would notably improve the overall environmental performance of the system. For instance, GHG emissions would be reduced by 85%.
This thesis addresses the problem of waste generation in international aviation. It presents quantitative and qualitative analysis detecting conflict points in this activity. In addition, useful alternatives for this sector are presented regarding not only waste management but also the design of catering menus that will reduce the net impacts along the life cycle.El transporte aéreo, en 2018, fue el medio de transporte elegido por 8.800 millones de personas en todo el mundo. Este es un sector que esperaba un crecimiento continuo de pasajeros en los a ños siguientes, pero que debido a los efectos actuales de la pandemia Covid-19 ha reducido sus proyecciones para 2020. Sin embargo, se espera que el sector vuelva a la normalidad tras el paso de la pandemia. La aviación fue responsable, teniendo en cuenta solo la combustión, del 2% de las emisiones de CO2 y del 12% de las emisiones totales de gases de efecto invernadero (GEI) del sector transportes en todo el mundo. Sin embargo, hubo más emisiones de GEI derivadas de esta actividad, entre otras, las emisiones generadas por el servicio de cáterin y su gestión de residuos. En 2018 se estimó que se generaron 5,7 millones de toneladas de residuos, que debían ser gestionados. La gestión de estos residuos en la Uni ón Europea está condicionada por la normativa europea CE 1069/2009. Este reglamento limita la gestión de los residuos orgánicos de origen animal generados en vuelos desde países fuera de la Unión Europea (la denominada "Categoría 1") al vertido o incineración. Tanto la introducción a esta tesis como el primer artículo científico describen en profundidad esta situación, así como el proyecto LIFE Zero Cabin Waste, en el que se han desarrollado. Caracterizar los flujos de residuos es fundamental para encontrar las complejas soluciones que requiere su clasificación y tratamiento. Sobre todo, en el sector de la aviación, en el que los diferentes tipos de residuos se recogen juntos y la mayor ía acaba en vertederos, generando emisiones de GEI y contribuyendo a la actual crisis climática. Se espera que, a partir de 2021, entre en vigor la Directiva 2019/904 y prohíba determinados plásticos de un solo uso que actualmente están muy presentes en los menús de aviación. Se ha realizado el estudio más completo hasta la fecha de caracterizaciones de los residuos generados durante 145 vuelos de diferente origen y características, permitiendo encontrar las fracciones mayoritarias y detectando posibles mejoras para reducirlas. Se ha comprobado que la fracción orgánica es mayoritaria (33%), y que otra fracción muy importante incluye los diferentes elementos y envases que encontramos en los menús. Para identificar el origen de los impactos más relevantes y encontrar soluciones a los diferentes problemas encontrados, se recomienda la metodología de Análisis de Ciclo de Vida (ACV), que permite evaluar desde la cuna hasta la tumba, dónde y por qué ocurren los impactos ambientales más relevantes. La aplicación de LCA evaluando 19 elementos y envases que incluye un menú turístico medio, muchos de plástico de un solo uso, otros reutilizables y de materiales más pesados, ha logrado identificar aquellos que más aportan a las emisiones de gases de efecto invernadero. Demostr ó que, contrariamente a lo esperado, las emisiones de GEI aumentarán con la introducción de esta nueva Directiva. Una vez recogidos por separado y clasificados por fracciones, los residuos pueden ser tratados de diferentes formas, siendo esta secuencia de procesos el sistema de gesti ón de residuos. Se han identificado puntos problemáticos del actual sistema de gestión, y se ha demostrado que algunos cambios en la gestión -que requerirían un cambio regulatorio en la UE que incluya la recogida selectiva en origen, la recuperaci ón de materia orgánica y el aumento de materiales recicladosmejoraría notablemente el comportamiento medioambiental global del sistema. Por ejemplo, las emisiones de GEI se reducirían en un 85%. Esta tesis aborda el problema de la generaci ón de residuos en la aviación internacional. Presenta análisis cuantitativos y cualitativos detectando puntos conflictivos de esta actividad. Además, se presentan alternativas útiles para el sector, que reducirán los impactos netos en el ciclo de vida.
