    Airspace deregulation for UAM: Self-organizing VTOLs in metropoles
    (University Aviation Association, 2022) Aldemir, Hüseyin Önder; Üçler, Çağlar; Professional Flight Program; Aviation Management; ALDEMİR, Hüseyin Önder; ÜÇLER, Çağlar
    Small-scale aviation has been driven extensively by recent technological developments. Distinct micro/small scale mobility modes are being interlined, where automated Vertical Take-Off and Landing Aircraft (VTOLs) are being conceptualized for Urban Air Mobility (UAM) in the form of air taxi, cargo, disaster relief, or medical help. This implicates many simultaneous flights over cities, which is a significant challenge. Traditional air traffic control is customized for commercial aviation, and it is not suitable for the dynamic variation in the flight routes of UAM. Consequently, a literature review is conducted firstly for air traffic management subject to UAM. Then, as a critical finding, a self-organizing model integrating particularly micro/small scale UAM is proposed utilizing the swarm concept to leverage the autonomous behavior of VTOLs. Rules for self-organization are set, which are then discussed in conjunction with available technologies such as Global Positioning System (GPS) and Traffic Alert and Collision Avoidance System (TCAS). Finally, the basic concept definition is elaborated to determine challenges and future research.

    Analysis of Turkey’s airport network structure and centrality in the opening-out period after the first wave of COVID-19: A complex network approach
    (Elsevier, 2022-12) Ersöz, Cem; Kılıç, Sena; Aldemir, Hüseyin Önder; Aviation Management; ERSÖZ, Cem; KILIÇ, Sena; ALDEMİR, Hüseyin Önder
    There are a few studies present analyzing air transport structures of the countries, regions, and the world by using complex network theory. Although Turkey has a complex air network with 56 airports, thorough research has not been carried out applying complex network analysis to reveal the structure of the airport network in Turkey yet. Furthermore, the fact that Turkey is a developing economy and the role of air transport in this development is undeniable, and its use as a transit area due to its geopolitical location, together with social and political factors, makes it important to understand this air transport network in detail. Consequently, in this paper, Turkey's Airport Network (TAN) topology was explored by implementing concepts of complex network theory using domestic and international passenger flight data gathered from FlightRadar during the opening period after the first wave of Covid-19. The average path length and clustering coefficient for connectivity performance and centrality metrics (degree, betweenness, and closeness) were computed and the network correlations were also measured and compared with simulated random, small-world (SW), and scale-free (SF) network models. Also, structural similarities and differences with the air networks of other countries are revealed.

    Competitive strategies in the airline industry
    (IGI Global, 2022) Sengur, F. K.; Aldemir, Hüseyin Önder; Akınet, M.; Aviation Management; ALDEMİR, Hüseyin Önder
    The airline industry is a dynamic industry with intense competition. Deregulation, the international competition structure, and economic and COVID-19-like crises make the sector even more fierce. In this chapter, airline industry competitive strategies are discussed. For this purpose, following the introduction part, the concepts of strategy, business strategy, and competitive structure of the airline industry are discussed, and the place of competitive strategies in business strategies is explained. The airline industry structure is analyzed using Porter's five forces model. Two fundamental competitive strategy approaches, Porter's generic strategies and Miles and Snow's competitive strategies, are examined in detail for the airline industry. Following the presentation of the two well-known strategy frameworks, the chapter will end with a conclusion part.

    Exploring strategic choices of airlines: A study in Turkish air transport industry
    (Penerbit Universiti Sains Malaysia, 2021-12-01) Aldemir, Hüseyin Önder; Şengür, F. K.; Ulukan, İ. C.; Aviation Management; ALDEMİR, Hüseyin Önder
    Inter-firm competition in the field of aviation, which accelerates through liberalisation and globalisation trends, has been investigated by numerous studies in the post-deregulation era; however, it has not been adequately addressed in Turkish aviation market. The aim of this study is to unveil the business strategies and strategic typologies of Turkish passenger carriers, as well as the degree of involvement of firms in the strategic planning process, the current outlook, and the competitive structure of the Turkish passenger air transport industry. The research is designed in a way to collect data through interviews with senior executives of the airlines. In terms of findings, the study concludes that five scheduled airlines and three charter airlines have attempted to implement more than one generic strategy at the same time as an “integrated cost and differentiation strategy,” with the primary strategy being cost leadership. Moreover, the passenger carriers in question displayed the features of “analysers-defenders” mainly linked to the competitive typology viewpoint. This study is believed to lead to a deeper understanding of potential explanations why companies have made specific strategic choices regarding generic strategies and strategic approaches. Regulators, individual companies operating in the aviation industry and prospective companies, investors, etc. can use the results of the study to regulate the market, better understand their competitors, set their priorities and plans, evaluate, and assess the market.
