International Journal of Aviation Management (IJAM)

Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

Online First articles are published online here, before they appear in a journal issue. Online First articles are fully citeable, complete with a DOI. They can be cited, read, and downloaded. Online First articles are published as Open Access (OA) articles to make the latest research available as early as possible.

Open AccessArticles marked with this Open Access icon are Online First articles. They are freely available and openly accessible to all without any restriction except the ones stated in their respective CC licenses.

  • A conceptual approach for aircraft readiness management through aircraft downtime optimisation   Order a copy of this article
    by Maria Makrygianni, Panagiotis Tsarouhas 
    Abstract: A framework for aircraft downtime optimisation in a military squadron was proposed. Military squadron was considered as a production system, producing operational aircraft. Each working day that an aircraft is out of service is a defective product. A group of 30 aircraft was studied in order to determine the proportion of defectives. Laney P chart depicted that the aircraft maintenance performance was in control. Nevertheless, two aircraft had undergone to unusual downtime interval. For these aircraft, cannibalisation, waiting and repairing time was analysed with partial least square regression. Eight points were came up as outliers and leverages. The analysis of these points revealed that airframe powerplant general (APG), communication/navigation, electrical and structure systems are undergone to long waiting and repairing time. While, recovery of fuel and electrical systems is downgraded by cannibalisation time. Incorporation of this methodology in aviation would strengthen the optimisation process of readiness, maintenance costs, quality and safety.

  • Insights from a mixed-methods Delphi study into the global airline industry   Order a copy of this article
    by Darren Ellis 
    Abstract: This paper looks at the key methodological and design insights gained from a five stage mixed-methods Delphi study investigating the global airline industry's likely future strategic trajectory. The exploratory study sequentially unfolded across a workshop, test/pilot survey, main survey 1, main survey 2, and finally in-depth interviews. The study revealed the important roles each stage played in gathering a wide array of salient data and informing subsequent stages and analysis. This research journey demonstrated the versatility available when mixing quantitative and qualitative methods in a Delphi study covering air transport, and how each can reinforce and complement the other. This is particularly relevant when investigating emerging air markets, where existing data are either limited or non-existent. Although a geographically dispersed multidisciplinary cohort of participants contributed to this study, more expert voices from under-researched emerging regions and air markets are evidently required for future research into this still expanding global industry.
    Keywords: Delphi study; emerging air markets; mixed-methods; global airline industry; strategic forecasting; liberalisation; protectionism; industry level analysis.

  • An Optimization Model of Environmental Pollutants for the Air Transport Network Based on Flight Altitude   Order a copy of this article
    by Alireza Ansariyar, Ali Abdi Kordani, Fatemeh Mohajeri, Babak Mirbaha 
    Abstract: The most important objectives of the air transport fleet design are meeting the travel demand in the network of existing trajectories, reducing costs and improving the emission rate of environmental pollutants. The environmental performance of the airline fleet is considered as a basic criterion for the design of air transport systems because of concerns in the area of global warming. In this study, the emission rate of environmental pollutants is separately measured, and logical relationships among fuel consumption, the emission rate of propellants, the volume of travel demand by airline fleet, and flight travel time are determined through using an optimization model based on system equilibrium conditions. Eventually, the optimization problem presented in a systematic air transport network is analysed and the results indicate that the emission of environmental pollutants is reduced by 64%.
    Keywords: air transport fleet; environmental pollutants; fuel consumption; travel demand; airline fleet; flight travel time.
