Towards improvement in aviation safety in Thai Airways International Public Company Limited: a model

Suthichoti, Supachoke Unknown Date (has links)
Thai Airways International Public Company Limited (THAI) is a very large organization compared to Thai standards. It generates huge incomes to a number of families, directly and indirectly. Like many airlines, the main concern with THAI and the regulatory authorities is safety because THAI is in a mass transportation business. THAI have had two accidents within a span of some six years, killing a total of 214 people. The accidents affected THAI in four key areas, namely political, economical, social and technological. This phenomenon prompted the study of aviation safety in THAI. The question that requires an answer is: “How should THAI build its protocols to enhance aviation safety?” This then became the research question. The objective of the study is to build a model suitable for THAI to enhance aviation safety, thus answering the question. Through a review of the literature within the parent disciplines, the product, process, and customers of flying activities were identified. The four processes, the MP, the HRD, the PM and the RS are recognized through rigorous search of the literature. The developments of the required seven elements of skills needed for pilot performance measurement were made.A review of study within the immediate discipline concerning Aviation Safety in THAI was carried out and the current status in THAI was defined. All of these led to the identification of research question, research objective, and research propositions. The research propositions were:• Research Proposition 1: that the management practice (MP) process receives inputs from the reporting system (RS) process. Outputs from the management practice (MP) process form inputs for the human resource development (HRD) process.• Research Proposition 2: that the human resource development (HRD) process receives inputs from the management practice (MP) process. Outputs from the human resource development (HRD) process form inputs for the performance measurement (PM) process.• Research Proposition 3: that the performance measurement (PM) process receives inputs from the human resource development (HRD) process. Outputs from the human resource development (HRD) process form inputs for the reporting system (RS) process.• Research Proposition 4: that the reporting system (RS) process receives inputs from the performance measurement (PM) process. Outputs from the reporting system (RS) process form inputs for the management practice (MP) process. • Research Proposition 5: that the individual process components identified in Research Propositions 1, 2, 3 and 4, can be consolidated into an overall, comprehensive Continual Improvement (CI) loop.Once the research propositions were established, the research design was conceived. Due to the fact that THAI is a unique airline influenced by its history of inception and by particular sets of cultures, an embedded, single case-study research method was used. Many techniques within the case-study method were employed starting from a secondary data search, direct observations, focus group interviews, elite interviews, pilot study, participant observations and in-depth interviews. Issues such as validity, reliability, sensitivity, generalizability and ethics were referred to. Issues on data processing, coding, editing, and interpreting were made and discussed.As a result of the various methods of study and the fieldwork previously mentioned, findings were derived. These were then edited, categorized, coded, tabulated and interpreted into meaningful information. Findings from the study and fieldwork supported all the propositions derived from secondary data search and literature review. Consequently the gap identified in the literature was now filled and the principal model was drawn. A slight modification was introduced in keeping with the interpretation of the findings. A recommendation was made that THAI implement policy measures and professional practices derived from the implication of the study to minimize risks in flight operations system and thus maximize safety.Based on the findings of this research, it is recommended that future studies be conducted employing a deductive, quantitative, statistical method to evaluate the model and test its theoretical implications.

The role and impact of services sector on economic growth : an econometric investigation of tourism and air services in Fiji (1968-2006) : a thesis presented in partial fulfillment of the requirements for the degree of Masters of Management in Economics at Massey University, Palmerston North, New Zealand

Qasenivalu, Mosese Tavaga January 2008 (has links)
Empirical studies have established that tourism is a major determinant of economic growth and that international air services have a beneficial effect on the growth and development of an economy. It has also been argued that trade and public enterprise reforms in the service sectors, undertaken to a greater extent in high income countries, have had a positive impact on the sectors performances. This study analyses several hypotheses relating to Fiji’s tourism and air transport service industries. First the study examines the contribution of tourism exports to economic growth in the case of Fiji. Second, the study analyses whether the tourism reform adopted by Fiji in 1999 under the World Trade Organization’s General Agreement on Trade in Services (GATS) has impacted on total tourism export performance. Third, the aviation-service growth nexus is investigated. Lastly, the effect of the aviation public enterprise reform activities on the export performance of air services is evaluated. Using time series annual data from 1968 to 2006, the Auto Regressive Distributed Lag. methodology has been utilized to estimate the contribution of each service sector to Fiji’s total service output. The results show that the tourism is a major determinant of growth in Fiji and that the aviation service-growth hypothesis is also valid for Fiji. The empirical results show that both the trade reforms in tourism and the pro-competitive measures undertaken in the airline industry, amongst other determinants, have not significantly created an impact on the respective export performance of tourism and air services. These findings provide key policy implications in the light of capitalizing on services exports as a major source of growth, particularly in developing island countries such as Fiji and the need to facilitate the strengthening of the market to boost the export performance of tourism and air services.

Aviation English in South African airspace

Coertze, Salome 03 1900 (has links)
Thesis (MA)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: A lack of English proficiency and failure to use standard phraseology played a role in two of the world’s largest aviation disasters in South Germany and Tenerife, respectively. As a result, the crucial role of effective pilot-ATC (air traffic controller) communication came under scrutiny and measures were put in place to ensure that aviation safety is not jeopardised by language-related problems. For example, the International Civil Aviation Organisation (ICAO) implemented English language proficiency standards and testing. The study reported in this thesis investigated the use of Aviation English and standard phraseology, which is used in radiotelephony communication by the operational aviation community. Aviation English consists of a range of operationally-relevant language functions and dialogue management, e.g. orders, requests, and offers to act; a blend of formulaic standard phraseology and plain or everyday speech if and when a non-routine situation occurs. Data on pilots’ and ATCs’ perceptions of the role of language in air traffic communication, their perspectives on English as lingua franca in aviation, and English language proficiency standards and testing were collected by means of a questionnaire. The respondents included full-time professional pilots (domestic and international flights), part-time professional pilots and pilots who fly for leisure, and ATCs in Air Traffic Navigation Service units that handle domestic and/or international flights. Recordings of on-site air traffic communication from two airport towers were obtained and were used to study the use of Aviation English and standard phraseology in pilot-ATC communication in South Africa. The results indicated that the majority of pilots and ATCs believe that language-related problems can cause fatal accidents and serious incidents. Pilots and ATCs in South Africa do experience threatening and potentially hazardous situations as a result of communication problems, however, they are confident that communication problems are resolved quickly and successfully in order to avoid accidents. The analysis of the voice recordings correlated with the pilots’ and ATCs’ perceptions that in spite of communication problems (languagerelated and non-language-related) occurring in South African airspace, pilots and ATCs have strategies in place to resolve them effectively and they are also able to use plain English to negotiate understanding and meaning. The majority of the respondents indicated that they agree that English should be used as the lingua franca in aviation around the world and they regard the English language proficiency of South African pilots and ATCs as satisfactory. The majority support ICAO’s English language proficiency standards and testing. The recordings presented a small percentage of transmissions with read-back/hear-back errors, but a substantial number of instances of radio distortions and background noise which interfered with the intelligibility of the transmissions, correlated with the results of the questionnaire. A small percentage of transmissions contained deviations from Aviation English and standard phraseology and/or the use of plain English. The researcher is of the opinion that this initial investigation into Aviation English serves to indicate some avenues for fruitful linguistic investigations into Aviation English and pilot-ATC communication in South Africa. / AFRIKAANSE OPSOMMING: Ontoereikende taalvaardigheid in Engels en nalating om standaard frases te gebruik, het bygedra tot twee van die ernstigste vliegongelukke in lugvaartgeskiedenis, naamlik in Suid-Duitsland en Tenerife, onderskeidelik. As gevolg van die ongelukke, het die kritieke rol van effektiewe kommunikasie tussen vlieëniers en lugverkeerleiers onder die loep gekom, en maatreëls is ingestel om te verseker dat lugvaartveiligheid nie deur taalverwante probleme benadeel word nie. Die Internasionale Burgerlugvaartorganisasie (IBLO) het byvoorbeeld, onder andere, taalvaardigheidsstandaarde en -toetsing vir vlieëniers en lugverkeerleiers ingestel. Die studie in hierdie tesis ondersoek die gebruik van Lugvaart-Engels (“Aviation English”) en standaard frases wat in radiokommunikasie deur die operasionele lugvaartgemeenskap gebruik word. Lugvaart-Engels bestaan uit ’n reeks operasioneel-toepaslike taalfunksies en gespreksbestuurmiddels, bv. instruksies, versoeke en ander handelinge; ’n mengsel van formele standaard frases en alledaagse Engels vir gevalle waar buitengewone of nie-roetine situasies hulle voordoen. ’n Vraelys is gebruik om inligting oor vlieëniers en lugverkeerleiers se sienings van die rol van taal in lugverkeerleiding in te samel, asook sienings oor die gebruik van Engels as lingua franca in lugverkeer en die IBLO se taalvaardigheidsstandaarde en toetsing vir vlieëniers en lugverkeerleiers. Die deelnemers sluit vlieëniers (voltyds en deeltyds, asook private en beroepsvlieëniers) in en lugverkeerleiers in lugverkeernavigasie-eenhede wat binnelandse en internasionale verkeer hanteer. Lewendige opnames wat van twee lughawetorings bekom is, is gebruik om taalverwante en ander kommunikasieprobleme tussen vlieëniers en lugverkeerleiers te ondersoek. Die resultate dui daarop dat die meerderheid vlieëniers en lugverkeerleiers van mening is dat taalverwante probleme tot noodlottige ongelukke en ernstige insidente kan lei. Daar is verder deur die deelnemers bevestig dat hulle dikwels in gevaarlike situasies beland waar kommunikasieprobleme tot die gevaar bygedra het, maar hulle is van mening dat kommunikasieprobleme in die Suid-Afrikaanse lugruim tydig en effektief opgelos word om ongelukke te vermy. Die opnames het met die bevindings van die vraelys ooreengestem en het aangedui dat, ten spyte van kommunikasieprobleme (taalverwant en nie-taalverwant) in die Suid-Afrikaanse lugruim, vlieëniers en lugverkeerleiers oor die vermoë beskik om sodanige probleme vinnig en suksesvol op te los. Dit het ook aan die lig gekom dat vlieëniers en lugverkeerleiers in Suid- Afrika daartoe in staat is om in alledaagse Engels te kommunikeer om enige onduidelikheid of buitengewone versoeke en instruksies te hanteer. Die meeste van die deelnemers meen dat vlieëniers en lugverkeerleiers in Suid-Afrika se taalvaardigheid in Engels bevredigend is en taalvaardigheidstandaarde en -toetsing word sterk ondersteun. Die lewendige opnames het ’n klein persentasie terugleesfoute bevat, maar ’n groot aantal gevalle van radiosteurings en agtergrondgeraas het met die hoorbaarheid en verstaanbaarheid van die kommunikasie ingemeng, wat met die resultate van die vraelys ooreengestem het. ’n Klein persentasie van die uitsendings het afwykings van Lugvaart-Engels en standaard frases en/of die gebruik van alledaagse Engels bevat. Die navorser is van mening dat hierdie studie die weg baan vir potensiële navorsing binne linguistiek ten opsigte van Lugvaart-Engels en die kommunikasie tussen vlieëniers en lugverkeerleiers in Suid-Afrika.

Análise dos modelos para cálculo de níveis de segurança relacionados à operação de veículos aéreos não tripulados. / Analysis of models for calculation of levels of security related to operation of unmanned aerial vehicles.

Cristiane Paschoali de Oliveira 16 June 2009 (has links)
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.
