La presente tesis es el resultado de una interacción de evaluaciones de campo como los resultados de los ensayos del sistema de canteras, pavimento existente, humedad natural, mix de aeronaves que operan y de topografía, así mismo de la traducción de manuales y catálogos, ya que nuestro País está afiliado y se rige por las Normas de la Organización de Aviación Civil Internacional (OACI), por los métodos de diseño de la Federal Aviation Administration (FAA) entidad oficial de la aeronáutica civil en los E.E.U.U. y a las especificaciones técnicas para al construcción de aeropuertos.

Die Darstellung der Beschäftigungswirkungen des Luftverkehrs spielt im politischen Leben in vielen westlichen Industrieländern eine große Rolle. Verbände der Luftverkehrswirtschaft versuchen, mit Gutachten die Bedeutung ihrer Branche für Wachstum und Beschäftigung zu untermauern. Viele dieser Gutachten halten keinen wissenschaftlichen Ansprüchen stand. Bereits 1992 hatte in den USA die amerikanische Luftverkehrsbehörde FAA die Qualitätsprobleme solcher Gutachten erkannt und bemängelt und Grundsätze für korrektes Arbeiten aufgestellt. In Österreich hat nun ein Streit um den weiteren Ausbau des Flughafens Wien zur Anfertigung mehrerer Interessentengutachten geführt. Diese Gutachten werden in der vorliegenden Studie evaluiert. Es zeigt sich, dass wissenschaftliche Standards nicht eingehalten werden. Die Regierung selbst verwendet Angaben aus solchen Gutachten in ihren Publikationen und tauscht stillschweigend Daten, die sich später als unhaltbar erweisen, gegen andere aus. Vergleiche mit Studienergebnissen von OECD, EU und Weltbank belegen große Differenzen. / Growth and Job-effects of Aviation play a crucial role in many western industrialized countries. Consortiums and federations of the aviation industry try to proof with assessments and expert opinions how important their sector is. However many of those studies do not have scientific quality. Already 1992 the American Federal Aviation Authority FAA realized problems and issued guidelines for acceptable reports. In Austria the planned enlargement of Vienna airport led to the production of several studies. This is the reason for the present paper. The most recent Austrian aviation studies, especially one by the Austrian IWI, are being analysed. It proves that the Austrian Aviation reports are not consistent with the standards set by the FAA guidelines. They contain exaggerated figures and omit critical aspects. Comparisons with studies of OECD, EU or Worldbank show the differences and imbalances.

<p>General Aviation (GA) is the foundation of most flying activities and the training ground for civilian pilots, both recreational and professional. However, the safety record for GA is lacking compared to that of commercial aviation. Approximately 75% of accidents each year involve personnel factors, that is, even if the pilot was not the cause of the accident, they could have done something to either prevent it or improve the outcome.<br></p> <p> </p> <p>In this research, I aim to improve GA safety through safety-driven post-flight debrief that encourages pilots to consider the risk in their flights and identify behavioral changes that could make their flying safer. Providing pilots with a debrief tool that they can use with or without a flight instructor requires that we know both what to communicate, and how to communicate it. Risk communication heuristics and biases have not been researched in the context of aviation and flight training and we therefore do not know how pilots understand or respond to debrief.</p> <p> </p> <p>To achieve the goals of this work, I used a three-step process: (1) identify events that may put the safe outcome of a flight at risk, (2) detect those events in flight data, and (3) inform the pilot in a way that helps them improve in their future flights. I use a state-based representation of historical aviation accidents to define a list of events or behaviors that need to be communicated to the pilots, in the form of states and triggers. I use flight data to retrospectively detect these behaviors upon completion of the flight, by mapping parameters or combinations of parameters that can be calculated and tracked in the flight data to the hazardous states and triggers defined. To present these events to pilots, I created a prototype interactive debrief tool with risk information that I use in a survey to evaluate the effectiveness of feedback in different representation formats. Specifically, I evaluate the impact of three factors: representation method (graphical and numerical), parameter type (safety and performance parameters), and framing language (risk-centric and safety-centric). </p> <p> </p> <p>I disseminated the survey via aviation mailing lists, type groups, flying clubs, and flight training providers, end received 268 responses. The survey analysis showed that the feedback representation does affect its effectiveness in terms of risk perception, but not when it comes to pilots’ motivation to change. The lessons learnt from this survey can be used in creating additional surveys that delve further into risk communication biases and our understanding of how pilots perceive risk and feedback.</p>

Busca-se encontrar a solução de compromissos para o desenvolvimento de uma aeronave multifuncional, de aviação geral, a pistão, que atenda às necessidades do mercado brasileiro e cujas características de desempenho estejam próximas ou superiores às das aeronaves típicas da aviação geral que operam nos Estados Unidos e Brasil. O objetivo principal do trabalho consistiu em desenvolver uma metodologia para projetos conceituais de aeronaves de pequeno porte e de uma família de aeronaves de forma que a geradora da família possa ser facilmente convertida em configurações diferentes, conservando o maior número de partes em comum, mantendo as características de desempenho almejadas e cumprindo com os requisitos de certificação impostos para a categoria. Apresentam-se definições, conhecimentos e técnicas na área de projetos aeronáuticos e descrevem-se de forma sucinta os aspectos mais importantes que envolvem o projeto conceitual. Em seguida é exposta a metodologia utilizada e são definidos os objetivos e os compromissos. Finalmente são apresentadas tabelas geradas pelo software PCA-Projeto Conceitual de Aeronaves e gráficos contendo as caracterizações onde se enquadra o objeto de estudo, a discussão e as conclusões da investigação. / The purpose of this work is to derive compromise solutions for the conceptual design of a general aviation aircraft, aimed to fulfill the requirements of the brazilian market. Fitted with a conventional piston engine, such aircraft should however sport technical and flight characteristics which are equal or better than those found on existing typical general aviation aircraft in operation both in Brazil and United States. The main objective of the thesis consisted of development of methodology for the conceptual design of a family of light aircraft so that the \"core aircraft\" can be regarded as a platform for the derivation and conversion to any of the family members - two, four and six - seats. Commonality of parts to the highest degree possible, achievement of a set of performance and efficiency goals and compliance with the existing certification requirements for the aircraft category are some of the main project drivers. The work presents the major topics definitions, the main specific techniques required in the subject of aircraft conceptual design followed by the key aspects associated with such an undertaking. The employed methodology is presented next, followed by the set objectives and compromise solutions so reached. Finally, the results for the three aircraft family are presented both graphically and in a set of data tables complemented by a few print-outs of the computer screen outputs generated by the software developed - PCA, which embodies the whole work carried out and can be used for the further improvements in the future. The conclusions present some critical analysis points and suggestions for the future work.

Desde o início do século XX que há registros do uso de Veículos Aéreos Não Tripulados (VANTs) utilizados com finalidade militar. Mas esta não é a única forma que se pode utilizá-los, o ambiente civil também é próspero em possíveis utilizações deste tipo de aeronave. Faltam ainda estudos e comprovações de que a integração dos VANTs no espaço aéreo juntamente com a aviação tripulada convencional não vá trazer alterações nos níveis de segurança já estabelecidos. Juntam-se a este desafio alguns outros, tais como padronizações de normas, classificações e legislação que regulamente o vôo das aeronaves não tripuladas. A presente dissertação faz uma coletânea de alguns modelos relacionados a cálculos de níveis de segurança no vôo de VANTs, bem como compara esses modelos entre si visando o estabelecimento de um método de escolha do modelo mais adequado para aplicação em alguns cenários civis de utilização. Esse trabalho ainda faz a aplicação desse método considerando os modelos relacionados à segurança dos VANTs. / There are records of the use of Unmanned Aerial Vehicles (UAVs) used for military activities since the beginning of the 20th century. But that is not the only way to use it; the civil environment is also promising as to the use of this kind of aircraft. More studies and validations have to be performed about the alterations in the safety levels with the integration of UAVs in the air space with classic manned air vehicles. There are others challenges such as the standardization of norms, classification and legislation to regulate the Unmanned Aerial Vehicle flights. This dissertation presents some models related to the calculation of the safety levels in UAVs flight, it compares them to establish a method for choosing the most suitable model to apply in some civil scenarios. This work also brings the application of this method considering the models related to the safety of UAVs.

Service quality is an integral part of the product/service offering provided to a customer. Along with continuously identifying customer expectations and perceptions about service quality, it is imperative for service providers to also investigate whether the service quality increases customer satisfaction and their behavioural intentions. This PhD study theoretically contributes by evaluating one comprehensive service quality model, SERVQUAL designed by Parasuraman et al. (1988), for its potential applicability. The study further contributes by identifying a gap in the literature that the original SERVQUAL model does not entirely represent LCC service quality therefore, LCCSQUAL is proposed: a revised conceptual model with twenty-five variables that reflect the industry-specific attributes of LCC services in the Middle East. LCCs became a common feature in the West after the appearance of Southwest airline in 1971, however in the Middle East; LCCs are a relatively new phenomenon. LCCs are growing rapidly due to the current development of the aviation industry, deregulation and open skies policies in many parts of the Middle East. Most research to date has focused on LCCs in Western or Asian culture, whereas limited research has been conducted in the Middle East region, hence, this study will focus on highlighting the historical development of the Middle East’s aviation industry and the phenomenal growth of the region’s LCCs. This research is first of its kind in the Middle East to be conducted on the LCC service quality as well as in a new cultural background and therefore, it is important to consider that passengers’ are influenced by their culture while making decisions, however; the original SERVQUAL model developed by Parasuraman et al. in (1985) does not include culture as one of the influences in consumer. This PhD study, therefore, bridges another gap in the knowledge by testing the LCCSQUAL in Middle Eastern culture. This PhD followed a multi methodology using both inductive and deductive approaches consisting of qualitative (interviews and a focus group discussion) and quantitative (a self-administered survey questionnaire) methods at Dubai International airport, which has a dedicated LCC terminal. A total of 540 questionnaires was distributed; however, only 516 were finally employed for quantitative analysis. For qualitative analysis, nine in-depth interviews with senior executives of LCC airlines and seven LCC passenger interviews was conducted along with one focus group interview with seven Emirati ladies, first time LCC travellers. Content analysis and NVivo 10 were utilised for qualitative findings and descriptive analysis, Spearman’s rank correlation, factor analysis and cross tabulation were employed to examine the quantitative results. Comparing the results of both methodologies indicated that, passengers experienced wider gaps in the tangibility, reliability and responsiveness dimensions of LCC service quality in the Middle East. The findings of the study concluded that LCC passengers have higher expectations of the LCC services due to receiving luxury services for a long time in the Middle East region. The revised model; LCCSQUAL was tested in the Middle Eastern culture with additional variables and is recommended to be further developed to be culture and country specific. Factor analysis results also highlighted that there are gaps between the expectations and perceptions of the passengers travelling with LCC. This study concludes with several recommendations to LCC management, such as, on-time performance, well-trained staff and crew members, providing clear information to the passengers and providing quality services with low fares.

Controlling the authenticity of a product in the supply chain has been a struggle formanufacturers, and increasing complexity of the chains intensifies the imitation andcounterfeiting threats. Indeed, counterfeiting is absent from effective control in supply chainand manufacturers are looking for a technology to supply this control. The ability of RFID toprovide a tagged item with unique electronic code, it’s characteristic to hold some historicaldata about the item and supply automatic, immediate and accurate data about the tagged itemattracts manufacturers to use RFID technology to provide the effective control throughout thesupply chain. In line with this issue, SToP1 (Stop Tampering of Products), an EU foundedproject, aimed at developing an anti-counterfeiting solution based on auto-identificationtechnologies for consortium companies concerned with or affected by fake products. SToP iscommitted to establish the business cases, do research and at the end issue applicationguidelines for using RFID technology against counterfeiting in particular business contexts.Under SToP’s umbrella, this master thesis is initiated with the purpose to design a practicalguideline for choosing an appropriate RFID system for anti-counterfeiting in the aviationindustry that is one of the affected industries.The conclusion of the thesis consists of a number of sections, which altogether fulfill thepurpose of the thesis. The thesis forms a base for continues challenge of implementing RFIDas an anti-counterfeiting device focusing on the aviation industry, proposes solution scenariosbased on RFID technology, suggests applicable standards and proposes a secure RFID methodto prevent counterfeiting specially in the aviation industry. Jointly, these sections fromguidelines as a foundation for decision-making for kind of RFID system for anti-counterfeitingapplication in the aviation industry. / Uppsatsnivå: D
