Over the last few years, the safety record of U.S. commercial airlines has improved to the point where the statistics on accidents are negligible. The overwhelming numbers of aviation fatalities occur in General Aviation (GA) accidents. While the fatal accident rate has improved—from around 5.0 per 100,000 miles flown in the post–World War II era to varying between 1.2 and 1.5 since 1996—it still results in 450 to 700 deaths per year. In 2013, improving GA safety was on the National Transportation Safety Board’s (NTSB’s) most wanted list. The NTSB has cited a lack of aeronautical knowledge as the cause of many of these accidents. If pilots are required to pass Federal Aviation Administration (FAA) knowledge and practical tests prior to obtaining a new pilot certificate, how could they not possess the knowledge needed to operate in the National Airspace System (NAS)? Some, attributing it to a failure to learn basic aeronautical knowledge, are concerned that potential pilots memorize the answers to test questions published in commercially available test guides and quickly forget the material after passing the test. The purpose of this retrospective causal comparative study was to see if airman knowledge tests scores are related to fatal accidents. Fatal GA accidents that had pilot error as a causal factor were compared with those in which maintenance factors caused the accidents, to see if there were significant differences in the pilots’ knowledge test scores. The time that potential pilots took to answer skill-based questions that required calculation or interpretation was compared to the time to answer recall questions to see if rote memorization may have been involved in passing the knowledge test. The results of this paper may have implications on how AFS 630 structures the FAA knowledge tests and how instructors prepare potential pilots for these tests.

Taylor, Andrew. "UK General Aviation accidents : increasing safety through improved training." Thesis, University of Leeds, 2014. http://etheses.whiterose.ac.uk/7884/.
Full textAbstract:
From January 2005 to December 2011 there were 1007 General Aviation, fixed wing accident reports published by the UK Air Accidents Investigation Branch. These ranged from minor events to fatal accidents, of which there were 55, killing 88 people. The data and information from these reports was collated and analysed to determine main and contributory causal factors with a view to formulating improvements to the current training and support mechanisms within the industry. A survey was also conducted among the UK General Aviation population to gauge the levels of experience, license level and other information with which the accident data could be compared, ultimately showing that although accident pilots were more experienced than the surveyed population of UK General Aviation pilots, they had less aircraft type experience. The accident data and survey results both mutually and independently highlighted areas of concern within General Aviation activities, such as the maintenance of flight currency, a lack of basic flight skills, poor decision making and an absence of any form of resource management. Some of these issues are more systemic in nature providing opportunity for additions and enhancements to be made to theoretical instruction, practical flight training and the support that General Aviation (GA) pilots receive, particularly those who fly with Private Pilot Licences, who make up the majority of this field of aviation. A rigid system of pilot monitoring to ensure currency is maintained and that appropriate procedures are followed prior to hire of an aircraft is also currently absent, being an area examined within the thesis. Proposals are presented to cover all these topics and conclusions drawn that whilst UK General Aviation is well regulated, the data and survey show there to be a need for improvements to be made, above and beyond the new syllabus being brought in under European Aviation Safety Agency regulations (EASA Part-FCL PPL, 2013).

Full textAbstract:
The thesis in the first part analyses the major international conventions with respect to liability exposure of airlines and aircraft operators performing international flights. Emphasis will be laid on the transportation of passengers, baggage and cargo and on the legal framework in place to award compensation for damages caused to persons and property on the surface of the earth.The study continues with an evaluation of natural hazards inherent to air transport and explains the typical standard aviation insurance policies and the scope of cover for the hull of the aircraft, for passengers and for third parties on the ground. Furthermore, an overview will be given of the 'extended exclusion clauses for Weapons of Mass Destruction (WMD)' commonly inserted in war risk insurance policies as a result of terrorist attacks.
Finally, this study will focus on the new insurance requirements implemented by the EU Regulation 785/2004 and its implication for air carriers.

Sobieralski, Joseph Bernard. "TAXATION OF UNITED STATES GENERAL AVIATION." OpenSIUC, 2012. https://opensiuc.lib.siu.edu/dissertations/502.
Full textAbstract:
General aviation in the United States has been an important part of the economy and American life. General aviation is defined as all flying excluding military and scheduled airline operations, and is utilized in many areas of our society. The majority of aircraft operations and airports in the United States are categorized as general aviation, and general aviation contributes more than one percent to the United States gross domestic product each year. Despite the many benefits of general aviation, the lead emissions from aviation gasoline consumption are of great concern. General aviation emits over half the lead emissions in the United States or over 630 tons in 2005. The other significant negative externality attributed to general aviation usage is aircraft accidents. General aviation accidents have caused over 8000 fatalities over the period 1994 - 2006. A recent Federal Aviation Administration proposed increase in the aviation gasoline tax from 19.4 to 70.1 cents per gallon has renewed interest in better understanding the implications of such a tax increase as well as the possible optimal rate of taxation. Few studies have examined aviation fuel elasticities and all have failed to study general aviation fuel elasticities. Chapter one fills that gap and examines the elasticity of aviation gasoline consumption in United States general aviation. Utilizing aggregate time series and dynamic panel data, the price and income elasticities of demand are estimated. The price elasticity of demand for aviation gasoline is estimated to range from -0.093 to -0.185 in the short-run and from -0.132 to -0.303 in the long-run. These results prove to be similar in magnitude to automobile gasoline elasticities and therefore tax policies could more closely mirror those of automobile tax policies. The second chapter examines the costs associated with general aviation accidents. Given the large number of general aviation operations as well as the large number of fatalities and injuries attributed to general aviation accidents in the United States, understanding the costs to society is of great importance. This chapter estimates the direct and indirect costs associated with general aviation accidents in the United States. The indirect costs are estimated via the human capital approach in addition to the willingness-to-pay approach. The average annual accident costs attributed to general aviation are found to be $2.32 billion and $3.81 billion (2006 US$) utilizing the human capital approach and willingness-to-pay approach, respectively. These values appear to be fairly robust when subjected to a sensitivity analysis. These costs highlight the large societal benefits from accident and fatality reduction. The final chapter derives a second-best optimal aviation gasoline tax developed from previous general equilibrium frameworks. This optimal tax reflects both the lead pollution and accident externalities, as well as the balance between excise taxes and labor taxes to finance government spending. The calculated optimal tax rate is $4.07 per gallon, which is over 20 times greater than the current tax rate and 5 times greater than the Federal Aviation Administration proposed tax rate. The calculated optimal tax rate is also over 3 times greater than automobile gasoline optimal tax rates calculated by previous studies. The Pigovian component is $1.36, and we observe that the accident externality is taxed more severely than the pollution externality. The largest component of the optimal tax rate is the Ramsey component. At $2.70, the Ramsey component reflects the ability of the government to raise revenue aviation gasoline which is price inelastic. The calculated optimal tax is estimated to reduce lead emissions by over 10 percent and reduce accidents by 20 percent. Although unlikely to be adopted by policy makers, the optimal tax benefits are apparent and it sheds light on the need to reduce these negative externalities via policy changes.

Falconer, Boyd Travis School of Aviation UNSW. "Attitudes to safety and organisational culture in Australian military aviation." Awarded by:University of New South Wales. School of Aviation, 2006. http://handle.unsw.edu.au/1959.4/25751.
Full textAbstract:
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.

Kirkland, Ian D. "The risk assessment of aircraft runway overrun accidents and incidents." Thesis, Loughborough University, 2001. https://dspace.lboro.ac.uk/2134/13270.
Full textAbstract:
The UK Civil Aviation Authority has recognised the need for protection against the runway overrun over and above the standard protection recommended by ICAO. Normal protection for the aircraft is provided in ICAO's Annex 14 by the strip at the end of a runway, and a recommendation for the installation of a Runway End Safety Area (RESA). In the UK, the CAA has stated that as part of their safety management system the aerodrome licensee should review the RESA distance requirement for their individual circumstances on an annual basis through a risk assessment. However, current industry knowledge of circumstantial factors in runway overruns is limited. Also, current models that are used to determine likely overrun wreckage locations and RESA dimensions take no account of the operational conditions surrounding the overruns or the aerodrome being assessed. This study has attempted to address these needs by highlighting common factors present in overrun occurrences through the compilation and analysis of a database of runway overruns, and through the construction of a model of wreckage location that takes account of the conditions at an individual aerodrome. A model of overrun probability has been constructed and the consequences of an overrun have been examined. One outcome of the study is an awareness that the industry is in an extremely poor state of knowledge of operational characteristics of non-accident flights, which if not addressed will be a major barrier to future advancement of aviation safety improvement and research.

Full textAbstract:
A study investigating what factors are present leading to pilots submitting voluntary anomaly reports regarding their flight performance was conducted. The study employed statistical methods, text mining, clustering, and dimensional reduction techniques in an effort to determine relationships between factors and anomalies. A review of the literature was conducted to determine what factors are contributing to these anomalous incidents, as well as what research exists on human error, its causes, and its management. Data from the NASA Aviation Safety Reporting System (ASRS) was analyzed using traditional statistical methods such as frequencies and multinomial logistic regression. Recently formalized approaches in text mining such as Knowledge Based Discovery (KBD) and Literature Based Discovery (LBD) were employed to create associations between factors and anomalies. These methods were also used to generate predictive models. Finally, advances in dimensional reduction techniques identified concepts or keywords within records, thus creating a framework for an unsupervised document classification system. Findings from this study reinforced established views on contributing factors to civil aviation anomalies. New associations between previously unrelated factors and conditions were also found. Dimensionality reduction also demonstrated the possibility of identifying salient factors from unstructured text records, and was able to classify these records using these identified features.ID: 029050666; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; Thesis (Ph.D.)--University of Central Florida, 2010.; Includes bibliographical references (p. 168-174).

Whipple, Julie Doran. "Crash Course: The Decisions That Brought Down United Flight 173." PDXScholar, 2015. https://pdxscholar.library.pdx.edu/open_access_etds/2364.
Full textAbstract:
In December 1978, United Airlines Flight 173 arriving in Portland from Denver with 189 people aboard crash-landed in a suburb at 157th and East Burnside. Ten people were killed and dozens more were injured. The jet ran out of fuel after it had circled for an hour while the crew tried to determine what was wrong with the right main landing gear, which had fallen with a huge double jolt on extension.
The investigation that followed the crash placed the blame squarely on the pilot for his negligence in failing to monitor his fuel supply, and secondarily on his crew members, who failed to adequately communicate their concerns about it. The accident was a watershed event in what would become known in the airline industry as crew resource management, a communication model designed to reduce human error by fostering collaborative decision-making and assertiveness training.
In the years that have followed the accident, very little has changed in the narrative surrounding it. Articles and docudramas on the plane crash consistently repeat the tale as is, blaming the pilot and shedding no light on the factors that led to the in-flight emergency or on United's role in contributing to the crash.
This thesis is a "cold-case" investigation that reveals those contributing factors, which have been so thoroughly ignored. In the words of renowned attorney F. Lee Bailey, "The rule of law requires that all parties who contribute to an accident share in the responsibility for whatever harm has been caused." This is the untold story of all the decisions that brought down United Flight 173, and of the responsibilities heretofore overlooked.

The research of glider pilot’s flying quality influencing personal stressors
Aim of the study:To estimate the personal stressors influence to the flying quality of glider pilot’s.
Methods:The instantaneous analytic research using questionnaires was made during the European gliding championship. Two types of questionnaires were created in English and given for the participants (n = 90) to fill every day, 90 before the flight and 90 after. All together 1.260 questionnaires were given and 742 were returned (58.9%). Statistical analysis was made with „Statistica for Windows“ and Microsoft Excel programs.
Results:Subjective pilots fatigue average increased 18.57% during the flight (stdev. 25.02%). At first fatigue increased, later decreased and at the end of the championship increased. Fatigue were increased by personal stressors, like the rest (r = 0.19, p<0.05), sleep duration (r = 0.15, p<0.05), coffee usage (r = 0.17, p<0.05). Fatigue decreased with tea usage (r = -0.19, p<0.05), short time of awake (r = -0.18, p<0.05). Most glider pilot’s noted that various health changes didn’t influence flying, but sweating importuned little. That was approved by objective measurements. Final results were determined by every day points (r = 0.57, p<0.05), pilot’s experience (r = 0.29, p<0.05), total flight time (r = 0.25, p<0.05), flight’s distance (r = 0.25, p<0.05), tea usage (r = 0.16, p<0.05), rest (r = 0.14, p<0.05).

Full textAbstract:
Passengers rank safety as a key factor in airline choice. Thus, safety performance impacts an airline's ability to attract customers. The purpose of this correlational study was to examine the relationship and difference between airline category low-cost carriers (LCCs) and full-service carriers (FSCs), geographical region, and safety performance measured by accident rates. The target population comprised all airlines in all countries that had an accident during the 14-year period 2004 to 2017. Data consisted of archival data of all global airline accidents and airline departure frequencies for the 14-year period. The theory of organizational accidents in complex sociotechnical systems explains the relationship between LCC and FSC safety performance, as well as between global geographical regions. The Swiss cheese model of organizational accidents theoretical framework remains a relevant model to examine airline accidents and improve airline safety. Data analysis consisted of the t test, ANOVA, correlation, and regression analysis. LCCs were found to be as safe as FSCs on a global level, and safer than FSCs in some regions. There were regional differences in safety, with North America being safer than Africa. The implications for positive social change include the potential for airline leaders to improve the safety image of their airline and provide passengers a better understanding of airline safety. Providing passengers with information on airline safety performance allows passengers to make informed choices on using different categories of airlines in different geographical regions. The research may result in new travel opportunities for travelers that were previously unrealized due to safety concerns, particularly around the increased use of LCCs.

Full textAbstract:
La République Démocratique du Congo (RDC) fut l'un des meilleurs modèles de l'exploitation aéronautique en Afrique pendant la colonisation et plus d'une vingtaine d'années après l'indépendance au point d'en être félicitée par l'Association Internationale des Transporteurs Aériens (IATA). Aujourd'hui, par contre, ce vaste pays situé au cœur de l'Afrique passe pour le mauvais élève de l'aviation civile mondiale sur le plan sécuritaire et le pire dans l'enregistrement des accidents et des catastrophes aériens depuis la libéralisation de ce secteur en 1978. Conséquence: la DOC est blacklistée par l'Union européenne depuis 2005 jusqu'à ce jour. Dans la mémoire collective et les médias, la RDC est ainsi assimilée aux crashes et aux catastrophes aériennes et le commentaire l'égratigne chaque fois que survient un accident aérien dans n'importe quel pays au monde. Cette étude s'inscrit dans la problématisation de la communication au sein des organisations. Elle questionne les nouveaux paradigmes de l'accident aérien dans le but de sa prévention en amont dans le transport aérien. La question principale concerne donc la communication en aéronautique civile. En effet, malgré l'imputabilité des occurrences comptabilisées en RDC soit à l'erreur humaine, soit à la technique, soit à l'environnement, soit à la conjonction de ces trois facteurs causaux, cette thèse doctorale démontre, dans une approche généalogicoprocessuelle, socio-anthropologique et macro systémique-technique aéronautique, que l'avalanche des accidents et des catastrophes aériens en RDC est consécutive à « la communication autistique», c'est-à-dire à « la normalisation de l'anormal, des dysfonctionnements, des déviances, des transgressions normatives», donc de « l'anormal normalisé» ou à un échange ou une communication procédant par les écarts aux normes de l'Organisation de !'Aviation Civile Internationale (OACI) dans un domaine très réglementé et très normalisé. Ainsi, l'étude décrit l'évolution de l'aéronautique civile congolaise des origines coloniales à ce jour. Elle fait une immersion dans les organisations ou les structures de son « collectif sécuritaire», en esquisse les types de communications, d'interactions, de relations et d'interrelations y entretenus, à savoir les incommunications, les communications paradoxales, ambigües, confuses, incompatibles, absurdes, l'aveuglement communicationnel ou déni de communication, les dialogues de sourds, communication de défense transpersonnelle, silences en tant que langue de bois. Enfin, cette recherche doctorale analyse sans complaisance les accidents et les catastrophes aériens survenus de 1990 à 2011 en ROC pour le démontrer et propose une théorie systémique du collectif sécuritaire de l'aéronautique civile comme « frein » aux pratiques communicationnelles autistiques en aviation civileThe Democratic Republic of Congo (DRC) was one of the best models of aeronautical exploitation in Africa during colonization and over a couple of decades after independence to the extent of being congratulated by the International Air Transport Association (IATA). Today, in contrast, this huge central African country (DRC) is the bad student in world civil aviation in terms of security and the worst in terms of air accidents and disasters since the sector was liberalized in 1978. The consequence is that ORC has been blacklisted by the European Union since 2005. In the collective memory and the media, DRC is associated with crashes and air disasters so that every lime there is a plane crash anywhere in the world, reference is made to ORC. This research questions the issue of communication within organizations. New paradigms of air accidents are questioned with the aim of their prevention upstream in air transport. The main research question is about communication in civil aeronautics. As a matter of tact, even though registered occurrences in ORC have been attributed either to human error or to technology, or to the environment, or sometimes to the combination of these three factors, results of this study conducted in a genealogic-process, socio-anthropological and macro aeronautical technically-systemic approach indicate that the avalanche of air accidents and disasters in ORC is due to "autistic communication", that is, "the normalization of the abnormal, dysfunction, deviances and infringement of standards", thus 'the abnormal standardized" or through communication that proceeds by discrepancies to standards of the International Civil Aviation Organization (ICAO) in a highly regulated and standardized field. The study depicts the evolution of Congolese civil aeronautics since its colonial origins until the present, it immerses itself in the organizations or structures of its "security sector", and outlines the types of communications, interactions, relations and interrelations that occur in there including paradoxical, ambiguous, confusing, incompatible, absurd communications, non-communications, communicational blindness or denial of communication, dialog of the deaf, transpersonal defense communication, silence as waffle. Finally, the research analyzes air accidents and disasters that occurred in DRC between 1990 and 2011 without leniency to demonstrate this and suggests a systemic theory of civil aeronautics security sector as "a brake" to autistic communicational practices in civil aviation

Griffin, Thomas G. C. "The flight of information : new approaches for investigating aviation accident causation." Thesis, Brunel University, 2010. http://bura.brunel.ac.uk/handle/2438/5175.
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.

Nous montrons que le paradigme actuel de stockage et d’organisation est mal adapté à l’utilisation réelle de ces documents et identifions des domaines problématiques ou les technologies du langage constituent une partie de la solution. Répondant précisément aux besoins d'experts en sécurité, deux solutions initiales sont implémentées : la catégorisation automatique de documents afin d'aider le codage des rapports dans des taxonomies préexistantes et un outil pour l'exploration de collections de rapports, basé sur la similarité textuelle. En nous basant sur des observations de l'usage de ces outils et sur les retours de leurs utilisateurs, nous proposons différentes méthodes d'analyse des textes issus du REX et discutons des manières dont le TAL peut être appliqué dans le cadre de la gestion de la sécurité dans un secteur à haut risque. En déployant et évaluant certaines solutions, nous montrons que même des aspects subtils liés à la variation et à la multidimensionnalité du langage peuvent être traités en pratique afin de gérer la surabondance de données REX textuelles de manière ascendanteThis thesis describes the applications of natural language processing (NLP) to industrial risk management. We focus on the domain of civil aviation, where incident reporting and accident investigations produce vast amounts of information, mostly in the form of textual accounts of abnormal events, and where efficient access to the information contained in the reports is required. We start by drawing a panorama of the different types of data produced in this particular domain. We analyse the documents themselves, how they are stored and organised as well as how they are used within the community. We show that the current storage and organisation paradigms are not well adapted to the data analysis requirements, and we identify the problematic areas, for which NLP technologies are part of the solution. Specifically addressing the needs of aviation safety professionals, two initial solutions are implemented: automatic classification for assisting in the coding of reports within existing taxonomies and a system based on textual similarity for exploring collections of reports. Based on the observation of real-world tool usage and on user feedback, we propose different methods and approaches for processing incident and accident reports and comprehensively discuss how NLP can be applied within the safety information processing framework of a high-risk sector. By deploying and evaluating certain approaches, we show how elusive aspects related to the variability and multidimensionality of language can be addressed in a practical manner and we propose bottom-up methods for managing the overabundance of textual feedback data
Тoзи реферат описва приложението на автоматичната обработка на естествен език (ОЕЕ) в контекста на управлението на риска в гражданското въздухоплаване. В тази област докладването на инциденти и разследването на произшествия генерират голямо количество информация, главно под формата на текстови описания на необичайни събития. На първо време описваме раличните типове (текстови) данни, които секторът произвежда. Анализираме самите документи, методите за съхраняването им, как са организирани, както и техните употреби от екперти по сигурността. Показваме, че съвремените парадигми за съхраняване и организация не са добре приспособени към реалната употреба на този тип данни и установяваме проблемните зони, в които ОЕЕ е част от решението. Две приложения, отговарящи прецизно на нуждите на експерти по авиационна сигурност, са имплементирани: автоматична класификация на доклади за инциденти и система за проучване на на колекции, основаваща се върху текстовото сходство. Въз основа на наблюдения на реалната употреба на приложенията, предлагаме няколко метода за обработка на доклади за инциденти и произшествия и обсъждаме в дълбочина как ОЕЕ може да бъде проложено на различни нива в информационнo-обработващите структури на един високорисков сектор. Оценявайки методите показваме, че трудностите свързани с многоизмерността и изменимостта на човешкия език могат да бъдат ефективно адресирани и предлагаме надеждни възходящи методи за справяне със свръхизобилието на доклади за инциденти в текстови формат

Thor, Sara, and Anna-Karin Rosén. "Military Aviation Incident Reporting from an HTO Perspective." Thesis, Industrial ergonomics, 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-19835.
Full textAbstract:
The purpose of this study is to find out if the Swedish Air Force and the military aviation industry, Saab Aerosystems, use an HTO perspective in incident investigations. The research objectives are to explore existing organizational and accident models, analyze the reporting system using the models, and suggest possible improvements to the existing incident investigation system. Fishman’s (1999) model for pragmatic studies was used to describe the study’s theoretical approach. Triangulation by literary review, case study and interviews were used to ensure validity and reliability.
Three models were chosen: Rollenhagen’s HTO model (1997), Leveson’s STAMP (2002), and Shappell and Wiegmann’s HFACS (2000). The models were further tested in the case study, revealing that their usefulness depends on type of incident, and that they leave a lot up to the investigator.
Interviews were conducted with key individuals at Saab Aerosystems as well as at the Swedish Armed Forces’ Headquarters. The interviews showed that the incident reporting system in question is a well functioning one, mainly due to the blame-free culture, multidisciplinary investigative teams, good feedback and a generally good knowledge of the HTO concept. Difficulties within the organizations exist due to organizational boundaries between the manufacturer and the operator, and recurring structural reorganizations within the Swedish Armed Forces. Saab acknowledges the emphasis on technical issues. The Flight Safety department at the headquarters is currently working with implementing HFACS into the Flight Safety Database.
Our recommendations for Saab Aerosystems and the Air Force include:
For Saab Aerosystems:
- Evaluate and learn from existing HTO work within the organization, and incorporate the results into existing processes and instructions for incident investigations.
- Make use of the theoretical models, where applicable, in the processes as well.
- Focus on HFACS in order to synchronize with the Air Force.
- Consider employing an HTO specialist.
For the Air Force:
- Consider influences from other HTO models, like Rollenhagen’s or Leveson’s models, while still in the development phase of implementing HFACS.
- Perform risk analyses regarding the effects on flight safety when doing reorganizations.
For both Saab Aerosystems and the Air Force we recommend:
Use Leveson’s model STAMP for complex and serious incidents, comprising of organizational, human and technical aspects.
Denna studie har som syfte att ta reda på om det svenska Flygvapnet och den militära flygindustrin, Saab Aerosystems, använder ett MTO-perspektiv vid incidentutredningar. Forskningsmålen är att utforska befintliga organisations- och olycksmodeller, att analysera rapporteringssystemet med hjälp av modellerna, samt att föreslå möjliga förbättringar på det existerande incidentrapporterings- och utredningssystemet. Fishmans (1999) modell för pragmatiska studier användes som teoretisk utgångspunkt. För att säkerställa validitet och reliabilitet användes triangulering, bestående av litteraturstudie, fallstudie, samt intervjuer.
Tre modeller valdes ut: Rollenhagens MTO-modell (1997), Levesons STAMP (2002) och Shappell och Wiegmanns HFACS (2000). Modellerna användes i fallstudien, med resultatet att modellernas användbarhet bedömdes variera beroende på typ av incident, samt att de lämnar mycket åt utredarens erfarenhet.
Intervjuer genomfördes med nyckelpersoner på Saab Aerosystems och på Försvarsmaktens Högkvarter. Intervjuerna visade att rapporteringssystemet i fråga är väl fungerande, främst tack vare rapporteringskulturen, de multidisciplinära utredningsgrupperna, god återkoppling och en generellt sett god kännedom om MTO-konceptet. Organisatoriska svårigheter är dels gränsdragningen mellan tillverkare och användare, dels återkommande omstruktureringar inom Försvarsmakten. Saab medger också att deras fokus ligger främst på det tekniska. Flygsäkerhetsavdelningen på Högkvarteret arbetar med att införa HFACS i flygsäkerhetsdatabasen.
Våra rekommendationer till Saab Aerosystems och till Flygvapnet inkluderar:
Till Saab Aerosystems:
- Utvärdera och drag lärdom av befintligt MTO-arbete inom organisationen, inkludera dessa resultat i befintliga processer och instruktioner för incidentutredningar.
- Utnyttja fler teoretiska modeller i processen, där så är lämpligt.
- Fokusera på HFACS för att synkronisera med Flygvapnet.
- Fundera på att anställa en MTO-specialist.
Till Flygvapnet:
- Fundera på att också införa delar av andra MTO-modeller, som Rollenhagens eller Levesons modeller, under implementeringsfasen av HFACS.
- Genomför riskanalyser av påverkan på flygsäkerhet vid omorganisationer.
Till både Saab Aerosystems och Flygvapnet rekommenderar vi:
använd Levesons modell STAMP vid mer komplexa och allvarliga incidenter som innefattar organisatoriska, mänskliga och tekniska aspekter.

In questo lavoro di tesi si è svolto in prima istanza uno studio preliminare atto a individuare una miscela rappresentativa del combustibile aeronautico Jet A-1, a partire dai limiti imposti dal mercato e dagli standard europei. Esso è stato identificato come miscela di n-decano e toluene in composizione relativa tale da avere proprietà chimiche e fisiche simili rispetto alla miscela reale.
Successivamente è stato individuato un set ridotto di cinetiche (reazioni) e di composti tale da rendere possibile l’implementazione in codici fluidodinamici computerizzati (CFD). Ciò è stato ottenuto utilizzando un'analisi di sensitività numerica e utilizzando il software Cantera.
Nella seconda fase del lavoro è stato utilizzato il software di simulazione dinamica di incendi denominato Fire Dynamic Simulator (FDS) sviluppato dal National Institute of Standards and Technology (NIST). Tale software è stato applicato per la simulazione degli incendi di pozza (pool fire) e per la simulazione della dispersione dei vapori del surrogato Jet A-1 su pista, seguito da un innesco ritardato (flash fire).
Nel caso del pool fire sono state valutate le temperature e i flussi termici radiativi in funzione del tempo e dello spazio. Nel caso della dispersione dei vapori del combustibile in atmosfera è stata invece valutata la frazione molare di combustibile presente nell’aria rispetto alla distanza dal punto sorgente, ed è stata valutata la dimensione della nuvola infiammabile avendo come riferimento il limite inferiore di infiammabilità della miscela in esame.
Il confronto con i dati sperimentali presenti in letteratura, in particolare per il pool fire - nei termini di flusso termico rispetto alla distanza dell’incendio - ha evidenziato una notevole discrepanza con i valori ottenuti dal modello di default di FDS, mentre ha invece confermato la bontà dei risultati ottenuti utilizzando il modello cinetico semplificato – ma di dettaglio - ottenuto in questo lavoro.

Full textAbstract:
This project examines the safety management of civil aircraft accident investigation authorities in International Civil Aviation Organization (ICAO) Member States, with particular emphasis on the independence of the investigations. The research aims to establish the current level of resources and methodology adopted by Member States’ accident investigation authorities. The output of this work not only identifies the current situation but informs initiatives for some of the States in the process of establishing their investigation capability.
ICAO Annex 13 was analysed and found to be based on the principle of independent accident investigations. Also, a four dimensional measuring index (4DMI) has been developed to measure the independence of accident investigations in ICAO Member States. Data were collected from 45 States and are presented in the thesis. As a result of applying the 4DMI to the collected data, the States were ranked according to their scores, and divided into four categories of independence. Analysis of the four categories and the scores from the four dimensions revealed that States approach the concept of investigation independence in different ways; however, there are several practices that are common within the highest independence category and several other practices that are common within the lowest independence category.
The research recommends that States should work towards improving their overall investigation independence by implementing the seven identified practices in the High-Independence category and distance themselves from the five practices identified as common in the Low-Independence category.

Previous issue date: 2011-02-28This paper discusses the structure and systematic procedures practiced by Brazilian aircraft maintenance centers and related to human factors. To survey and analysis of information, exploratory research techniques were employed, looking for an overview on the subject through interviews with people responsible for the area of human factors in the participating aircraft maintenance centers. A descriptive study was conducted through a questionnaire which was answered by twenty employees with different occupations. The main objective was to analyze the practices covered by each participating organization in relation to eight aspects relevant to the prevention of human errors in aviation maintenance: 1) Error Management, 2) Training in Human Factors, 3) Fatigue Management, 4) Pro-activity of the Organization in Support Human Factors, 5) Motivation for the Program of Human Factors and Safety, 6) Metrics for Human Factors 7) Support of State Regulatory Aviation and 8) Policies of the Organization. To allow a comparative analysis, the standard questionnaire used was similar to that employed by the board of American aviation FAA - Federal Aviation Administration in an applied research involving aircraft maintenance centers in several countries. The results showed that the national service centers have greater disabilities when related to aspects of error management, fatigue management and support of aviation regulators. The better results were found in the aspects of human factors training. It is expected a contribution, by making suggestions and recommendations, for the safety of aircraft maintenance activities in order to prevent incidents and accidents caused by human error.
O presente trabalho aborda a estruturação e sistemática dos procedimentos praticados por centros brasileiros de manutenção aeronáutica em relação aos fatores humanos. Para o levantamento e análise das informações, foram empregadas técnicas de pesquisa exploratória, procurando obter uma visão geral e aproximada sobre o assunto através de entrevistas com as pessoas responsáveis pela área de fatores humanos dos centros de manutenção aeronáutica participantes. A pesquisa descritiva foi conduzida através da aplicação de questionário nas mesmas empresas, a qual foi respondida por vinte funcionários com diferentes ocupações. O objetivo foi analisar as principais práticas abordadas por cada organização em relação a oito aspectos importantes para a prevenção de falhas humanas na manutenção aeronáutica: 1) Gerenciamento de Erros; 2) Treinamentos em Fatores Humanos; 3) Gerenciamento de Fadiga; 4) Pró-atividade da Organização em Suportar Fatores Humanos; 5) Motivação para o Programa de Fatores Humanos e Segurança; 6) Métricas para Fatores Humanos 7) Suporte dos Órgãos Regulamentadores de Aviação e 8) Políticas da Organização. Para possibilitar uma análise comparativa, o modelo de questionário utilizado foi similar ao empregado pelo órgão de aviação americano FAA Federal Aviation Administration em pesquisa aplicada em centros de manutenção aeronáutica de diversos países. Os resultados obtidos demonstraram que os centros de serviços nacionais possuem deficiências quando relacionados aos aspectos de gerenciamento de erros, gerenciamento de fadiga e ao apoio dos órgãos regulamentadores de aviação. Os resultados mais satisfatórios foram encontrados nos aspectos alistados ao treinamento em fatores humanos. Espera-se contribuir, através do estudo, com a segurança das atividades de manutenção aeronáutica, visando à prevenção de incidentes e acidentes causados por falha humana através de sugestões e recomendações advindas do diagnóstico levantado durante a realização deste trabalho.

Full textAbstract:
The need for any aviation authority to have an alert and more so, efficient accident or incident
investigation mechanism cannot be over emphasized particularly in present day aviation practice. It
is thus, in the best interest of any state, not only to be on the high alert in the event of an accident
occurring. As well as also having sufficient resources and expertise, to engage in the investigative
process. A significant factor to the carrying out of such investigations is off course, the manner in
which such process is regulated. More so because investigations of this nature can only be carried out
and addressed in a manner stipulated as a matter of law.
It would therefore follow, that the legislation which directly regulates the process in which the
investigations are carried out should be both succinct and clear. Further, it should also adhere
strictly to internationally established guidelines of due conduct in the occurrence of accidents.
Aircraft accident and incident investigations are central to the observance of safety in aviation as a
sector. Thus, the realization of aircraft safety in aviation is a central function of any aviation
authority. It is a role so central, that it is one that is internationally recognised and harmonised.
Though not a matter of enforced International law, international best practice in this field is
established in a convention, in particular the International Convention on Civil Aviation of 1944,
which is more commonly referred to as the Chicago convention. As all treaties and/or conventions
this is an opt?in regulatory mechanism, in which only member states bind themselves. Therefore,
where a state becomes a signatory to same and has bound itself, it is of crucial importance that it
observes the laws or regulations to which it has bound itself.
As a matter of course, individual state compliance at times even for mere ratification purposes has
proved over time to be a tricky process for numerous states. This is particularly prevalent in
developing countries. Some texts have attributed this to various aspects, such as lack of necessary expertise and resources amongst other factors. Whatever the reason however, it is important that
states eventually comply with regulations laid out in conventions, so as to achieve harmonisation in
processes of International applicability.
This research paper seeks to take an in depth look into to the extent to which Swaziland as a member
state of the Chicago convention, has achieved compliance with the set guidelines of the Chicago
Convention. However, the report will confine itself to aircraft safety as the focal point, and in
particular, focus on the specific regulatory mechanisms that relate to aircraft accident and incidents.Mini Dissertation (LLM)--University of Pretoria, 2015.

Full textAbstract:
Human related accidents in high-risk industries amount to a significant economic hazard and incur tremendous damages, causing excessive operational costs and loss of life. The aviation industry now observes human-related accidents more frequently than in the past, an upswing attributable to cutting-edge technology usage and the complex systems employed by aviation organizations. Historically, aviation accidents have been attributed to individual unsafe behavior. However, contemporary accident causation models suggest that organizational-level factors influence individual safety performance, as human-related accidents take place in an organizational context. The present study examines the formation of organizational safety culture and influence on individuals safety behavior in a police aviation environment. The theory of planned behavior guides the study model in explaining individual variability in safety behavior via organizational safety culture. The study conceptualized organizational safety culture and individual safety behavior as multidimensional constructs. Confirmatory factor analysis was conducted for each latent construct to validate the construct validity for each measurement model. Organizational safety culture was observed via safety climate facets, which contained four subcomponents including individual attitude, group norms, management attitude, and workplace pressures. Individual safety behavior contained violation and error components observed by self-reported statements. Structural equation modeling was conducted to test the study hypotheses. Utilizing a sample of 210 employees from the Turkish National Police Aviation Department, a 53-item survey was conducted to measure individuals safety culture perceptions and self-reported safety behaviors. The results suggest that individual safety behavior is significantly influenced by organizational safety culture. Except for the relation between workplace pressures and intention, all suggested relations and correlations were statistically significant. The four-factor measurement model of organizational safety climate fit reasonably well to the data, and most correlations between the safety climate components were significant at the .05 level. Individuals self-reported error behavior is positively associated with age, and individuals self-reported violation behavior is positively associated with years of service. Overall, along with organizational safety culture, age and service-year variables accounted for 65% of the variance in intention, 55% of the variance in violation behavior, and 68% of the variance in error behavior. Lastly, no significant difference manifested among pilots, maintenance personnel, and office staff according to their self-related safety behaviors. The findings have theoretical, policy, and managerial implications. First, the theory of planned behavior was tested, and its usefulness in explaining individuals safety behavior was demonstrated. The survey instrument of the study, and multi-dimensional measurement models for organizational safety climate and individual safety behavior were theoretical contributions of the study. Second, the emergence of informal organizational structures and their effects on individuals indicated several policy implications. The study also revealed the importance of informal structures in organizations performing in high-risk environments, especially in designing safety systems, safety policies, and regulations. Policy modification was suggested to overcome anticipated obstacles and the perceived difficulty of working with safety procedures. The influences of age on error behavior and years of service on violation behavior point to the need for several policy modifications regarding task assignment, personnel recruitment, health reports, and violation assessment policies. As well, managerial implications were suggested, including changing individuals perceptions of management and group attitudes toward safety. The negative influence of anticipated obstacles and the perceived difficulties of safety procedures on individual safety behavior pointed out management s role in reducing risks and accidents by designing intervention programs to improve safety performance, and formulating proactive solutions for problems typically leading to accidents and injuries.Ph.D.

Full textAbstract:
Safety is very important for our society. In contrast, it is hard to define what this term really means. Nevertheless, one area that is considered important for safety involves accident prevention. Many methods exist within this area which aims at preventing accidents from happening. One accident prevention method is called ‘The Safety Scanning Tool (SST)’. The study conducted in this thesis aimed at exploring whether the SST could improve the safety understanding of experts from the domain of aviation. The term ‘safety understanding’, as it is used in this thesis, refers to the understanding of central scientific concepts underlying safety. These concepts relate to the area of accident prevention and they were the results of a literature study on safety. Thus, the safety understanding was addressed on two levels of abstraction. The first general abstraction level concerned the basic assumptions for studying an organization’s safety culture relating to Schein’s (1992) framework cited by Guldenmund (2000). This relates to the area of accident prevention in a more general way. The second more specific abstraction level regarded 21 different safety issues important for accident prevention. These originated from the area of resilience engineering. Furthermore, this study was structured as a field experiment using a pre-post test and a within-group design. In order to measure the different experts’ safety understanding, the data were gathered with the help of two surveys before and after the experts’ used the SST. The SST was applied to two groups of experts. In the first group, they were six people, and, in the second 16. The questions in the surveys were created with the help of the above mentioned literature study on safety. The results were analyzed with the help of the statistics program SPSS. In addition, the results were analyzed with the help of sources from academic literature. These were used in order to determine whether there was an improvement of the safety understanding or not. Based on the results from this study, it can be concluded that undergoing the SST caused several improvements of the experts’ safety understanding. These improvements were found in both groups of experts and on both abstraction levels of the safety understanding. However, one result relating to the basic assumption level in the second group of experts could be interpreted both as an improvement and as a decrease of the safety understanding. The results of this study indicate not only that the SST has the ability to detect safety problems in an early state, before they can develop to the outcome of an accident. It has also the ability to enhance its user’s safety understanding relating to factors important for accident prevention.

Full textAbstract:
There are many pieces of flight deck research on general use of written English language
technical information and problem solving using technical documentation. Contributory
causes of aircraft accidents have been due to misunderstandings of crew alerts and procedural
divergence by English as-a-second language flight crewmembers (ESL). Research was
conducted to understand impact of written English language technical information on ESL
flight crewmembers’ performance. Two types of systems were evaluated, technical
documentation and crew alerting systems that contain technical information, with respect to
their impact on ESL flight crewmember performance. Preliminary analysis results indicated
written English language technical information can be confusing, difficult to read and
interpret, and leads to misunderstandings by ESL flight crewmembers during aircraft nonnormal
conditions. English as-a-second language flight crewmembers indicated they often
experience problems executing written English language technical procedures after outset of
crew alerts.
Conversely, experimental trials revealed ESL flight crewmembers did not experience many
cognitive performance issues with use of crew alerting systems and technical information
designed with an English language emphasis. English as-a second language flight
crewmembers’ English language proficiency, background knowledge, and use of use of
metacognitive strategies to read and comprehend written English language on crew alerting
and information systems, indicated they utilized written English technical information with
ease. Particularly, ESL flight crewmembers’ workload was low, they had fast response times
to system faults, and they experienced minimal procedural deviations. On the contrary, when
ESL flight crewmembers utilized written English language technical procedures translated
into their native language during non-normal conditions, they experienced several cognitive
performance challenges. English as-a second language flight crewmembers’ background
knowledge of written English language technical information translated into their native
language, use of metacognitive strategies to read and comprehend written English language
translated into their native language, indicated they experienced difficulties with reading and
comprehending translated technical information on information systems. Particularly, ESL
flight crewmembers were challenged cognitively when they responded to crew alerts through
execution of decision-making processes. They indicated translation of written English
language technical information into their native language was a pre-cursor to procedural
deviation, long response times to system issues, as well as high workload during
experimental trials.
It is recommended that further research focus on design and use of written English language
technical documentation by ESL flight crewmembers during non-normal conditions. It is also
recommended that if deemed practical by the aviation industry, further research should focus
on design, integration, and utilization of technical documentation in a language(s) other than
English, and measurement of ESL flight crewmembers performance on the flight deck.

Full textAbstract:
We present the results of flight simulator experiments (60 runs) with randomly selected airline pilots under realistic operational conditions and discuss them in light of current fuel regulations and potential fuel starvation. The experiments were conducted to assess flight crew performance in handling complex technical malfunctions including decision-making in fourth-generation jet aircraft. Our analysis shows that the current fuel requirements of the European Aviation Safety Agency (EASA) are not sufficient to guarantee the safety target of the Advisory Council for Aviation Research and Innovation in Europe (ACARE), which is less than one accident in 10 million flights. To comply with this safety target, we recommend increasing the Final Reserve Fuel from 30 min to 45 min for jet aircraft. The minimum dispatched fuel upon landing should be at least 1 h.

The operation of aviation industry is complex and with risky. The prevention of aviation accidents have been the focus of researches. Although the strategies of aviation accident prevention are continuously updated, the frequency of accidents is not significant reduced. This may means that the modern concept of accident prevention is unable to provide effective prevention means. This study, based on cognitive systems engineering perspective and the concept of functional resonance accident model, is to develop a method for foreseeing the possible aviation accidents scenarios from the scenario of an occurred accident. The results of this study show that the method is able to identify possible accident scenarios. These accident scenarios could provide a wider scope on dealing with aviation safety.

Find full textAbstract:
General Aviation (GA) is a category of aircraft operations, exclusive of all military and commercial operations. According to Federal Aviation Administration (FAA), fixed-wing aircraft (also known as airplanes) account for 76.2% of all the estimated registered GA fleet in the United States. Out of all the GA accidents that the National Transportation Safety Board (NTSB) investigated in 2017, 87.7% of the accidents involved fixed-wing aircraft. The NTSB reports on all GA accidents and records the accident details in their database. The NTSB database has an abundance of accident data, but the data is not always logically complete and has missing information. Many researchers have conducted several studies to provide GA fixed-wing accident causation using the NTSB accident data. The quantitative analyses conducted by the researchers focused on a chain of events approach and identified the most frequent events in accidents. However, these studies provided little insight into why the events in the accidents happened. In contrast, the qualitative analyses conducted an in-depth study of limited accidents from the NTSB database. This approach helps in providing new findings but is difficult to apply to large scale datasets. Therefore, our understanding of GA fixed-wing accident causation is limited. This research uses a state-based approach, developed by Rao (2016), to provide a potentially better understanding of causes for GA fixed-wing accidents. I analyzed 10,500 fixed-wing accidents in 1982–2017 that involved inflight loss of control (LOC-I) using the state-based approach. I investigated the causes of LOC-I using both a conventional approach and a state-based approach. I analyzed fatal, non-fatal and overall LOC-I accidents in three timeframes: 1989–1998, 1999–2008 and 2008–2017. This multi-year analysis helped in discerning changes in the causation trends in the last three decades. A mapping of the LOC-I state definition to the NTSB codes helped in identifying 2350 more accidents in the database that were not discernible using the conventional approach. The conventional analysis revealed “directional control not maintained” as the top cause for the LOC-I accidents, which provides little information about how loss of control happened in accidents. The state-based analysis highlighted some important findings that contribute to LOC-I accidents that were not discernible using the conventional approach. The state-based analysis identified preflight mechanical issue as one of the new causes for LOC-I with a presence in 5.1% of LOC-I accidents in 2009–2017. It also helped in inferring some of the missing information in the accident data by modeling the accidents in a logical order. Using the logic rules in the state-based approach, I inferred that the pilot’s tendency to hit objects or terrain caused loss of control in 19.9% of LOC-I accidents in 2009–2017. Further, the logic rules helped in inferring that 7.5% of LOC-I accidents in 2009–2017 involved hazardous condition of an aircraft before the start of flight. A comparison of the findings from state-based approach with the GAJSC (General Aviation Joint Steering Committee) safety enhancements revealed that the state-based approach encompassed all the potential issues addressed in the safety enhancements. Additionally, a state-based analyses of larger datasets of fatal and non-fatal accidents suggested some new potential issues (such as improper maintenance) that were not explicitly addressed in the GAJSC safety enhancements.

Cabin safety standards and training are important for maintaining safe aircraft operations, and aim at increasing the survival rate by minimizing hazards in the cabin and its environment to reduce the effects of an accident. This study designes a comprehensive survey based on discussions with aviation safety experts. And next a new framework of four major cabin-safety indicators that influence occupant survivability is proposed: (1) aircraft design and loading, (2) cockpit- and cabin-crew training and coordination, (3) passenger behavior and safety education, and (4) ability to cope with emergencies inside and outside the airport. Moreover, 47 possible survival factors are generalized and categorized under these four indicators. The Fuzzy Delphi Method is used to identify and rank the survival factors that may reduce injury and fatality in potentially survivable accidents. This study presents two empirical studies of Singapore Airlines (SIA) flight SQ006 and China Airlines (CAL) flight CI120 to illustrate the critical factors that influence airplane occupant survivability. This study also explores the cabin safety perceptions of passengers from their emergency evacuation experiences in an actual aviation accident. The data from the passenger perception questionnaire are analyzed using the factor analysis method. Finally, risk assessment matrix, risk priority number and achievability of four risk management policies are used to propose some recommendations in cabin-safety management. The study findings reveal important cabin-safety and survivability information that should provide a valuable reference for developing and evaluating aviation safety programs. The findings indicate that the crew assistance and emergency procedure are the most important factors from aviation safety experts’ opinions and the passengers’ perspectives. The results will be practical for designing cabin-safety education material for air travelers and encourage improvements that will promote more successful cabin-safety management.

The Grey System Theory is a recently developed system of theories, which enables analysis without complete collected data. Unlike most common statistics, which is dependent on large quantity of facts and figures. The Grey System Theory allows the leeway on uncertainty, discrete data, and incomplete collected data. The Grey System Theory covers vast range of areas. In example of the recent Aviation Accident report, Grey Correlation Analysis and Grey Prediction were utilized, in conjunction with information from WAAS (World Aircraft Accident Summary). In addition to most common Grey Correlation Analysis methods, professor Wu, Han-Shon’s modified Grey Correlation Analysis was also used for analyzing the system of correction. The Grey Prediction System was practiced on different GM (1,1) and GM (1,N) models. It successfully corrected miscalculations and inaccurate results. The use of the Grey System Theory enables us to effectively understand the cause of aircraft accidents. This knowledge is an important reference which enable us to prevent future aircraft accidents and to improve the safety of aircraft travel.

The general purpose of this study was to determine whether a relationship exists between
emotional awareness and human error in aviation. A quantitative analysis approach was
used to explore this by means of a cross-sectional survey design. The independent
variable emotional awareness and the dependent variable human error were
contextualised and operationalised. During the empirical phase, biographical information
was collected and the Hartmann Emotional Boundary Questionnaire was administered to
a purposive sample consisting of 173 aircrew members within the South African Air Force.
Factor analysis revealed an eight-factor structure: involved; exactness; blend; openness;
structured; unstructured; flexibility; and imagination. No differentiation was found between
the mustering groups in relation to emotional awareness and human error. However,
correlations differentiated between aircrew with zero human error and aircrew with “more
than ten years’ aviation experience”. The test for differences between human error and
the emotional awareness sub-construct "imagination" indicated a medium significance.
From this relationship, the researcher deducted that “imaginative aircrew are prone to
err”.Industrial and Organisational Psychology

Full textAbstract:
This study examines the differences between the skills and competencies of New Zealand flight school graduates and the types of skills and competencies believed to define a proficient air transport pilot. In New Zealand the training of professional pilots is directed towards meeting the requirements laid down by the New Zealand Civil Aviation Authority for the licensing of professional pilots. However, some evidence suggests that competence for licensing purposes does not necessarily meet the requirements of the airlines and the types of skills that they require as a prerequisite to airline training. Although not clearly defined, this shortfall has been recognised for several decades and traditional thinking is that extra flying experience gained as a general aviation pilot will develop the skills necessary for entry into airline pilot training. The importance that pilots of differing experience levels attach to technical and non-technical skills and their perception of the training effectiveness of those skills and how deficiencies in those skills contributed to aircraft accidents was explored by a four stage study including: i) a review and analysis of flight test results obtained from graduate pilots on a university air transport pilot programme; ii) the analysis of responses to questionnaires supplied to three pilot groups within the New Zealand aviation industry; iii) the analysis of air transport aircraft accidents and their primary and contributing causes; and iv) interviews with qualified airline pilots working for New Zealand airlines. The results indicated that throughout the spectrum of experience and qualifications, from student pilot to airline pilot, the technical skill of aircraft handling was highly valued and the training in this skill was considered by all pilots to be satisfactory. In contrast, while non-technical skill deficiencies were found to be primary or contributing factors in many aircraft accidents, less importance was attached to non-technical skills by all pilot groups. The training effectiveness of these skills was rated as only moderately effective or of minimal effectiveness. The findings are discussed and recommendations are made for the improvement of basic flight training. In addition, a model is proposed for the fast tracking of flight school graduates into the airline training schools. Several areas for future research are also proposed.

Based on the investigation of Flight Safety Committee, there were a total of 75 aviation accidents in the past ten years（2007-2016）domestically and abroad. Among them, the number of aviation accidents taking place in the civil aviation transportation industry was as high as 43, and the other 32 cases happened in the general aviation industry, for business purposes, and among ultralight aircraft and foreign aircraft. Firnstahl pointed out in 1989 that when the aviation industry's service mistakes occur, service compensation will make customers more satisfied with the errors caused in the service process. Kelley and Mark indicated in 1994 that service compensation is a process where businesses attempt to make up for the mistakes of service delivery. In addition, Gronroos pointed out in 1988 that service compensation stands for actions taken by service providers in response to their faults. On the other hand, based on cost-benefit analysis, the cost of attracting a new customer is five times that of maintaining an old customer.（Desatnick,1988） Bauer was the first scholar to develop the concept of perceived risk from a psychological perspective.(Bauer,1960) It was considered that consumers who believe in the concept of perceived risk may have risky behaviors, and the actions they take may produce unpredictable results. Moreover, these results may cause consumers to feel unpleasant; therefore, he believes that when consumers are under the condition of uncertainty, perceived risks are generally prevalent in consumer behaviors. As a continuation of Bauer’s theory, Cox further clarified the concept of perceived risk. It was considered that when consumers perceive their purchases might not reach their buying goals, or even cause adverse consequences because of being unable to fulfill expected goals, perceived risks thus occur.(Cox,1967) Reichheld and Sasser considered that customer satisfaction will increase customer loyalty, implying that customer repurchase intentions will increase, which will enhance the purchase times and quantity of the customers.(Reichheld and Sasser,1990) What’s more, Kotlor believed that customers will have some degree of satisfaction or dissatisfaction in their hearts after purchases or services. If satisfied, customers will be more willing to repurchase.

This research details the development of civil aviation risk analyze models. We define the aviation risk as the frequency of aviation events. Based on the FSMIS (Flight Standard Management Information System) database developed by CAA (Civil Aviation Administration), three prediction data mining techniques, multiple regression analysis, back propagation neural network, and support vector machine, are used to create prediction models for different type of aviation events. The FSMIS database contains the information of air operators’ safety performance in various inspection items. Using the information, the relationship between events and operation performance is analyzed and the event prediction models are created. According to our study results, it appears that a data smoothing strategy is very effective at enhancing the predictive accuracy of the models. The methodological comparison suggests that back propagation neural network and support vector machine offer a more promising technology in prediction aviation risk.

Due to the frequent air crash in recent years, the standard operating procedure (SOP) of emergent rescue to aircraft accident has been concerned. Take While with TransAsia’s air crash in Keelung River, Nangang, Taipei, on 2015/02/14, all of us paid attention to the acts adopted by our government and the efficiency through media. This thesis intends to seek the possibility for our military with improvement on SOP of emergent rescue with detailed discussion. This thesis utilizes Focus Group interviews and Balanced Scorecard (BSC) methodology as analysis for finding out remissness. Besides, there’s also the questionnaire with four dimensions: "Financial", "Customer", "Internal Processes" and "Learning and Growth" through the application of BSC, and with the firemen as the interviewees for further consideration of rescue. The results can be referred or further rescue process, and with less damage and casualty after the amendment of SOP of emergent rescue for aviation. The investigation intends to check the relevance among gender, education and seniority. On the “Customer” perspective (soldiers involved in aircraft rescue), 52.1% believe more budget for simulated expense to be crucial. 47.9% consider the procurement of equipments same as civil ones from radio, vest, etc., to be important. On the “Financial” perspective, 49% mention the exhaustion caused by insufficient recruitment, with the side-effect of hunger, thirst, hotness, and coldness, to be the main factor affect the rescue 46.9% complain the unspecified command tires the military by unable recruitment and with jeopardy for the rescue. On the “Internal Process” perspective, 58.3% think the rescue training with diversified aircraft should be indispensable. 49% ask the government for integrated procedures of command for better communication and command system. On "Learning and Growth” perspective, 49% declare the twice-a-year training to be insufficient, and should be with more practices. Furthermore, some want varied scenarios incorporating into training courses. Due to some restrictions, the questionnaire results from relevant soldiers are quite low, but the results still manifest the evident. During the process, the proportion of female interviewees is low, which can affect the effectiveness of the survey. Further interview should be mingled with civil rescue groups, fire units, and relevant staffs, and the application of BSC could be engaged with oral inquiry for thorough indication Key words：aircraft accident、standard operating procedure (SOP)、Focus Group Interview、Balanced Scorecard (BSC)

The risk management is an executive routine of risk identification, appraisal and control. If used wisely, it could greatly improve both the management operations and the security level. The point of risk management is not to avoid the risk, but to face the risk by using a systematic way which therefore reduces the risk. However, due to time restrictions and limited resources, the problem solving methods should be efficient, low risk, and economical. In addition, risk management is highly related to the aviation safety because related personnel’s ultimate goal is to prevent similar accidents, investigate causes, and improve the efficiency of risk management. This research applies risk management procedures to the domestic civil aviation industry fixed-wing aircraft aviation safety analysis. First, this essay uses aviation and transportation management safety documents as the research foundation to emphasize the importance of an aviation risk management to the aviation transportation industry. Next, the essay bases the research on a causes/factors statistics of domestic civil aviation industry fixed-wing aircraft first and second level accidents during the period of 1998-2007. The causes/ factors of aviation accidents can be divided into seven different categories including pilots, other personnel, weather, airports, tower controls, navigational aids, and engine/ aircraft structure. Afterward, the research combines the statistics and professional accident investigation contents to calculate an aviation accident risk ratio, and to acknowledge a risk matrix. According to my research, pilots are responsible for most accidents (14.3%) based on the accident causes/factors. The least frequent causes for accidents are airports, tower controls, navigational aids, and engines (0%). In addition, aircraft structures lead to the highest damage range (270 risk points), while airports, tower controls, navigational aids, and engines also have the smallest damage range (0 point). Furthermore, the risk area analysis indicates that pilots, other person personnel, and weather are in the high-risk area, and that aircraft structure is in the middle-risk range, and airports, tower controls, navigational aids, and engines are in the low risk area. Lastly, this research presents aviation accident risk management strategies and suggestions for risk improvements.

Air transportation is not limited by the cause of landforms, it is so speedy, safe, economic, and comfortable that has become one of the most important transportation. Air transportation also insists of risks leading to accident, such as bad weather, human overlooking, or a breakdown of air machines. Thus, when air accident occurs, case concerning the liability of air carrier occurs. However, the regulation framework of liability of air carrier of the Convention for the Unification of Certain Rules for International Carriage by Air and the Civil Aviation Law of R.O.C. insists the difference of framework that bring different outcome whether the protection for air carrier is sufficient or not. Therefore, this essay will introduce and discuss the contents regarding the liability of air carrier of the Civil Aviation Law of R.O.C. and the Convention for the Unification of Certain Rules for International Carriage by Air； ICAO Doc.9740, this essay will try to generalize a regulation pattern through induction method afterwards to compare the advantage and disadvantage of these two laws to protect the right of carriers.
