Item A Cross Sectional Study of the Ten Longest Ultra-Long-Range Air Routes(Sciendo, 2019) Glenn Baxter; Panarat Srisaeng; Graham WildIn recent times, several airlines have commenced the operation of ultra-long-range (ULR) services. Using a mixed methods research approach, this paper examines the aircraft deployment, the target passenger market segments, the aircraft cabin configurations, the flight stage lengths and the available seat kilometres (ASKs) produced on the world's ten longest air routes. The study found that some airlines are operating ultra-long-range services on a hub-to-hub basis, whilst other airlines are operating these services to open new spoke city markets. The case airlines are targeting the premium and leisure travel market segments. The Boeing 787-9 is the most popular aircraft type for these services followed by the Airbus A380-800 and the Boeing B777-200LR aircraft. Qatar Airways Doha to Auckland service has the longest flight stage length (14,535 kilometres). The other 9 air routes all exceed 13,400 kilometres in length. The greatest number of annual ASKs are produced on the Emirates Dubai to Auckland services (5.09 billion ASKs) and the smallest number of annual ASKs are on the Qantas Airways Perth to London services (2.49 billion ASKs). � 2019 Transport and Telecommunication Institute, published by Sciendo.Item A Cross Sectional Study of the Ten Longest Ultra-Long-Range Air Routes(Sciendo, 2019-04-01) Glenn Baxter; Panarat Srisaeng; Graham WildIn recent times, several airlines have commenced the operation of ultra-long-range (ULR) services.

Wild; RMIT University, School of Aerospace, Mechanical, and Manufacturing Engineering, Melbourne, 124 La Trobe Stm, 3000, Australia; email: graham.wild@rmit.edu.auThis study has proposed and empirically tested for the first time genetic algorithm optimization models for modelling Australia�s domestic airline passenger demand, as measured by enplaned passengers (GAPAXDE model) and revenue passenger kilometres performed (GARPKSDE model). Data was divided into training and testing datasets; 74 training datasets were used to estimate the weighting factors of the genetic algorithm models and 13 out-of-sample datasets were used for testing the robustness of the genetic algorithm models. The genetic algorithm parameters used in this study comprised population size (n): 200; the generation number: 1,000; and mutation rate: 0.01. The modelling results have shown that both the quadratic GAPAXDE and GARPKSDE models are more accurate, reliable, and have greater predictive capability as compared to the linear models. The mean absolute percentage error in the out of sample testing dataset for the GAPAXDE and GARPKSDE quadratic models are 2.55 and 2.23%, respectively. � 2015, Journal of Aerospace Technology and Management.

Wild; School of Engineering and Information Technology, University of New South Wales, Canberra, 2612, Australia; email: g.wild@adfa.edu.auAircraft maintenance includes all the tasks needed to ensure an aircraftÕs continuing airworthiness. Accidents that result from these maintenance activities can be used to assess safety. This research seeks to undertake a preliminary investigation of accidents that have maintenance contributions. An exploratory design was utilized, which commenced with a content analysis of the accidents with maintenance contributions (n = 35) in the official ICAO accident data set (N = 1277), followed by a quantitative ex-post facto study. Results showed that maintenance contributions are involved in 2.8 ± 0.9% of ICAO official accidents. Maintenance accidents were also found to be more likely to have one or more fatalities (20%), compared to all ICAO official accidents (14.7%). The number of accidents with maintenance contributions per year was also found to have reduced over the period of the study; this rate was statistically significantly greater than for all accidents (5%/year, relative to 2%/year). Results showed that aircraft between 10 and 20 years old were most commonly involved in accidents with maintenance contributions, while aircraft older than 18 years were more likely to result in a hull loss, and aircraft older than 34 years were more likely to result in a fatality. © 2020 by the authors.

Around the world airlines are increasingly focusing on the environmentally sustainable energy management. Using a qualitative longitudinal case study research approach, this study examines FinnairÕs sustainable energy management over the period 2010 to 2019. The airlineÕs major energy source is jet fuel used for the operation of the airlineÕs aircraft fleet and the electricity which is used to power its facilities located at Helsinki Airport. The study found that FinnairÕs annual jet fuel consumption has grown throughout the study due to the airlineÕs route network and aircraft fleet expansion. The fuel required for ground vehicles has risen reflecting greater operational requirements due to the companyÕs expansion. The annual consumption of electricity and electricity for heating has displayed a general downward trend during the study period. The annual electricity per passenger has also decreased despite the large growth in passenger numbers. Finnair has increased its use of renewable energy sources for its flight and ground operations. A key energy saving strategy has been the acquisition and operation of a modern state-of-the-art, fuel efficient aircraft fleet. © 2021, World Scientific and Engineering Academy and Society.

Wild; School of Engineering, RMIT University, Melbourne, Australia; email: graham.wild@rmit.edu.auHuman factors have been defined by the International Civil Aviation Organization (ICAO) as �about people in their living and working situations; about their relationship with machines, with procedures and with the environment about them; and about their relationships with other people (at work)�. Human factors contribute to approximately 75% of aircraft accidents and incidents. As such, understanding their influence is essential to improve safety in the aviation industry. This study examined the different human factors causations in a random sample of over 200 commercial air transport accidents and incidents from 2000 to 2016. The main objective of this study was to identify the principal human factor contributions to aviation accidents and incidents. An exploratory research design was utilised. The qualitative data were recorded in a database, and were coded into categories about the flights (including date, manufacturer, carrier, state of occurrence, etc). These categories were then analysed using Chi-Squared tests to determine which were statistically significant in terms of having an influence on the accidents/incidents. The most significant human factor was found to be situational awareness followed by non-adherence to procedures. In addition, charter operations proved to have a significantly higher rate of human factor related occurrence as compared to other type of operations. A significant finding was that Africa has a high rate of accidents/incidents relative to the amount of traffic and aircraft movements. These findings reflect some of the more noteworthy incidents that have received significant media attention, including Air Asia 8501 on the 28th of December 2014, TransAsia Airways 235 on the 4th of February 2015, and Air France 447 on the 1st of June 2009; these accidents resulted in a significant loss of lives where situational awareness and non-adherence to procedures were significant contributing factors. � 2018Item Airport Related Emissions and their Impact on Air Quality at a Major Japanese Airport: The Case of Kansai International Airport(Sciendo, 2020) Glenn Baxter; Panarat Srisaeng; Graham WildThe objective of this study was to investigate the carbon dioxide (CO2) emissions of an airport, to determine if strategies are helping to achieve sustainability targets. Kansai International Airport was selected as the case study, and it is Japan's third largest airport and there was readily available comprehensive data to enable a study to be undertaken. The airport has a dedicated environmental division and has implemented various initiatives over the past decade or so to reduce the airport's impact on the surrounding environment, especially since it is in Osaka Bay. The research used an exploratory design, with an initial qualitative case study, followed by a quantitative longitudinal study, utilizing correlation to assess trends over time. Results showed statistically significant reductions in carbon dioxide (CO2) emission from the three facets of airport operations, both in terms of the number of passengers and number of aircraft serviced by the airport. As a result, the initiatives undertaken at Kansai International Airport could be adapted and used by other airports to help reduce their carbon dioxide emissions. © 2020 Glenn Baxter et al., published by Sciendo.Item Airport Related Emissions and their Impact on Air Quality at a Major Japanese Airport: The Case of Kansai International Airport(Sciendo, 2020-04-01) Glenn Baxter; Panarat Srisaeng; Graham WildThe objective of this study was to investigate the carbon dioxide (CO2) emissions of an airport, to determine if strategies are helping to achieve sustainability targets.

In the ANFIS, both the learning capabilities of an artificial neural network (ANN) and the reasoning capabilities of fuzzy logic are combined to provide enhanced prediction capabilities, as compared to using a single methodology. Sugeno fuzzy rules were used in the ANFIS structure and the Gaussian membership function and linear membership functions were also developed. The hybrid learning algorithm and the subtractive clustering partition method were used to generate the optimum ANFIS models. Data was normalized in order to increase the model's training performance. The results found that the mean absolute percentage error (MAPE) for the overall data set of the PAX and RPKs models was 1.52% and 1.17%, respectively. The highest R2-value for the PAX model was 0.9949 and 0.9953 for the RPKs model, demonstrating that the models have high predictive capabilities. © 2015 Vilnius Gediminas Technical University (VGTU) Press.Item An assessment of airport sustainability, part 1-waste management at Copenhagen Airport(MDPI AG, 2018) Glenn Baxter; Panarat Srisaeng; Graham Wild; G. Wild; School of Engineering, RMIT University, Melbourne, 3000, Australia; email: graham.wild@rmit.edu.auAirports play a vital role in the air transport industry value chain, acting as the interface point between the air and surface transport modes. However, substantial volumes of waste are produced as a by-product of the actors' operations. Waste management is therefore becoming especially important to airports. Using a qualitative and quantitative case study research approach, this paper has examined the waste management strategies and systems at Copenhagen Airport, Scandinavia's major air traffic hub, from 1999 to 2016. The two major sources of waste at Copenhagen Airport are the waste generated from aircraft serving the airport and the waste arising from ground activities undertaken in the land and airside precincts. The growth in passengers and aircraft movements has had a concomitant impact on the volume of waste generated. Swept waste and sludge are processed by an external provider. Waste generated in the passenger terminals and the airport operator's facilities is handled at a central container station, where it is sorted for incineration, recycling or for landfill. The environmental impact of the waste produced at the airport is mitigated through the recycling of waste wherever possible. � 2018 by the authors.Item An assessment of airport sustainability, part 1-waste management at Copenhagen Airport(MDPI AG, 2018-03-01) Glenn Baxter; Panarat Srisaeng; Graham WildAirports play a vital role in the air transport industry value chain, acting as the interface point between the air and surface transport modes.

Wild; School of Engineering, RMIT University, Melbourne, 3000, Australia; email: graham.wild@rmit.edu.auAirports play a critical role in the air transport value chain. Each air transport value chain stakeholder requires energy to conduct their operations. Airports are extremely energy intensive. Greenhouse gases are a by-product from energy generation and usage. Consequently, airports are increasingly trying to sustainably manage their energy requirements as part of their environmental policies and strategies. This study used an exploratory qualitative and quantitative case study research approach to empirically examine Copenhagen Airport, Scandinavia's major air traffic hub, sustainable airport energy management practices and energy-saving initiatives. For Copenhagen Airport, the most significant environmental impact factors occurring from energy usage are the CO2 emissions arising from both the air side and land side operations. Considering this, the airport has identified many ways to manage and mitigate the environmental impact from energy consumption on both the air and land side operations. Importantly, the application of technological solutions, systems and process enhancements and collaboration with key stakeholders has contributed to the airport's success in mitigating the environmental impact from energy usage at the airport whilst at the same time achieving energy savings. � 2018 by the authors.Item An Assessment of Airport Sustainability, Part 2—Energy Management at Copenhagen Airport(MDPI AG, 2018-06-01) Glenn Baxter; Panarat Srisaeng; Graham WildAirports play a critical role in the air transport value chain.

The substantial growth of aviation has led to a significant increase in water usage by airports. Airports also generate large volumes of wastewater that may include contaminants. Hence, understanding sustainable water management practices is essential in the aviation industry. In this study, an exploratory research design was utilized in the examination of the sustainable water management strategies and systems at Kansai International Airport from 2002 to 2016. The qualitative data were examined using document analysis as part of a case study. The quantitative data were analyzed using regression analysis as part of a longitudinal study. The airport has been able to reduce the total water consumption, water consumption per passenger, and water consumption per aircraft movement, even with increased traffic in recent years. The airport sources water from the municipal authorities and reclaims water for non-potable water uses. The airport conducts regular water quality tests which measure the Chemical oxygen demand, total nitrogen, and total phosphates. The airport’s onsite wastewater processing centre processes all wastewaters, which discharges non-reclaimed water into Osaka Bay. With a decrease in water consumption, there has similarly been a decrease in the need to treat wastewater, while the reclaimed water ratio has increased over the period of the study. © 2018 by the authors.Item An assessment of sustainable airport water management: The case of Osaka�s Kansai international airport(MDPI Multidisciplinary Digital Publishing Institute, 2018) Glenn Baxter; Panarat Srisaeng; Graham Wild; G.

Baxter; School of Tourism and Hospitality Management, Suan Dusit University, Huahin Prachaup Khiri Khan, 77110, Thailand; email: g_glennbax@dusit.ac.thAirlines around the world are increasingly focusing on the environmentally sustainable management of wastes produced as a by-product of their operations. The objective of this work was to analyze FinnairÕs non-hazardous waste (NHW) types and quantities, their NHW management strategies, and the methods used to mitigate the environmental impact of their NHW, over the period 2008 to 2019. To achieve these objectives, the study was underpinned by an in-depth mixed methods research design; this incorporated a quantitative longitudinal study and a qualitative document analysis. The results revealed that despite significant growth of their operations, FinnairÕs annual NHWs have declined over the study period. FinnairÕs annual NHWs decreased from 5,710 tonnes in 2008 to 4,212.01 tonnes in 2019. The primary waste disposal methods used by the airline are waste-to-energy recovery and waste recycling, both in-house and by external third-party service providers. Smaller quantities of wastes are composted. Since 2015, the company has had a policy of not disposing wastes to landfill. © 2021, Kauno Technologijos Universitetas. All rights reserved.
