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.

A new digital service quality model and its strategic analysis in aviation industry using interval-valued intuitionistic fuzzy AHP
(Elsevier, 2020-07) Buyukozkan, G.; Havle, Celal Alpay; Feyzioglu, O.; Professional Flight Program; HAVLE, Celal Alpay
Today, airline companies have to provide digital products and services to ensure customer satisfaction. Accordingly, classical service quality models are not sufficient to capture customer expectations, and new digital service quality (DSQ) models should emerge. This study aims to propose a new and genuine DSQ model. The proposed model consists of digital tangibles, reliability, digital interaction, digital trust, and customer-centricity dimensions; and 35 criteria related to them. Importance degrees of criteria are determined with the IVIF AHP method. The validity of the proposed model is verified, employing a real case concerning the Turkish airline industry. The results show that the most significant dimension is digital trust, and the three most important criteria are proactive customer service, cybersecurity, and customer insight.

Traveler's idle time and the value chain at airports
(Milli Savunma Üniversitesi Hezârfen Havacılık ve Uzay Teknolojileri Enstitüsü, 2015-07-23) Üçler, Çağlar; Martin-Domingo, Luis; Professional Flight Program; Aviation Management; ÜÇLER, Çağlar; DOMINGO, Luıs Martın
There is a high growth in the air traffic supported by the global trade and tourism and due to airport congestion travelers are spending more time at airports, which are competing to attract airlines with lower aeronautical costs reducing their profitability. The growing transit time spent at airports together with the waiting time in front of check-in, passport, security control or baggage claim is an idle time of the air traveler, which is not generating any value. The perception of waiting is also mostly negative, that the associated airports are disliked, leading to loss of revenue in commercial offerings. Another problem is that due to the high variety in the customer profile, the shops at the airports need to carry a high inventory over a wide spectrum of items required, which is not creating any value as well. Thus in order to deliver a sustainable value chain at the airport, an innovative customer focused integrated approach is proposed herewith, based on a smart phone platform called Gate Ø, facilitating the idle times of the air traveler. This strategic approach is evaluated successfully within a value chain analysis showing up its potential across the value chain stakeholders.

The impact of leadership styles on performance and mediating effect of organizational culture: A study in flight schools
(Elsevier, 2022) Gökalp, Pınar Horasanlı; Soran, Semih; Professional Flight Program; SORAN, Semih; HORASANLI, Pinar
Nowadays, the aviation sector is growing rapidly and the need for human resources in the airline industry is increasing. In order to meet the increasing pilot need, the number of flight schools and universities that provide pilot training with the support of relevant authorities is also increasing. This increase in the number of student pilots is accompanied by questions about how to ensure the continuity of quality and safety in flight training. In this context, it is very important for the flight schools to evaluate the variables that may affect the student pilot performance and to take the necessary precautions. In our study teacher leadership and organizational culture are assessed as important variables and examined. In aviation literature, there is a very small number of explanatory studies on flight performance and leadership. Additionally, no study has been found on teacher leadership of student pilots. In this context, how leadership styles affect student pilots' performances positively and negatively was investigated in our research. Organizational culture is considered as an important predictor of performance in today's organizations. In this context, it has emerged that studies have been carried out that the organizational culture is an important variable in improving organizational and individual performance. Leadership styles of teacher pilots and organizational culture have been explored in the student pilots' performance process. In this context, our work has included performance, leadership styles and organizational culture. Regarding the methodology part of this study, 151 student pilots in the flight training organizations formed the universe and a survey was conducted, analysed and explained. Considering the effect of dynamic leadership, the present study analysed the impact of leadership and culture on flight performance. It is assumed that the most effective leadership styles can be found within group dynamics consisting of members who have diverse and individual cultural orientations. Individual differences that are caused by cultural norms can be considered as the outcomes of leadership behaviour. It was concluded that flight crew leadership cannot be analysed without considering the culture variable since behaviour is influenced by both individual and environmental factors. Moreover, since the performance outcomes of the crew resource management were evaluated, the cultural attitude of the crew and leader was considered.

(Dumlupınar Üniversitesi, 2014) Şeşen, H.; Soran, Semih; Caymaz, E.; Professional Flight Program; SORAN, Semih
Girişimcilik son dönemlerde ekonomik olgusunun yanında sosyal özelliklerinin ön plana çıkmasıyla çok önemli bir konu haline gelmiştir ve gün geçtikçe inceleme alanları artmaktadır. Girişimcilik, fırsatlardan yararlanarak var olan parçaları bir araya getirmek ve pazar payı oluşturmak olarak tanımlanabilir. Girişimcilik niyeti doğuştan gelen veya sonradan kazanılan özelliklerle, risk, karar verme ve yönetme gibi fonksiyonları kullanarak süreci hayata geçirme faaliyetidir. Girişimcilik niyeti bireysel ve toplumsal birtakım olgulardan etkilenebilmektedir. Kültür ve sosyal ağların da girişimcilik niyeti açısından önemli bir yere sahip olduğu değerlendirilmektedir. Bu çalışmanın amacı toplumsal kültürel değerlerin öğrencilerin girişimcilik niyetlerine etkisinde, öğrencinin sosyal ağını kullanma şeklinin önemli bir aracı rolü olup olmadığının incelenmesidir. Girişimcilik Niyeti, Toplumsal Kültürel Değerler ve Sosyal Ağ Kullanımını ölçmek ve değerlendirmek için üç farklı anket kullanılmıştır. Anketler dört ayrı üniversitede öğrenim gören 358 öğrenciye uygulanmıştır. Anketlerden elde edilen veriler SPSS istatistik programında analiz edilmiştir. Elde edilen bulgular, toplumsal kültürel değerlerin öğrencilerin girişimcilik niyetlerine etkisinde sosyal ağ kullanımının, toplulukçuluk alt boyutu için kısmi, belirsizlikten kaçınma için tam aracılık etkisine sahip olduğunu göstermiştir.

Stress among ab-initio pilots: A model of contributing factors by AHP
(Elsevier, 2019-09) Kılıç, Bilal; Üçler, Çağlar; Professional Flight Program; KILIÇ, Bilal; ÜÇLER, Çağlar
Human error in the cockpit triggers a chain of incidences, which might lead in aviation to fatal consequences. Indeed, it is the highest contributor to aviation accidents, where stress is correlated positively. Despite the large research base for commercial or military pilots, there is no study related to the workplace stressors of ab-initio pilots. With these considerations in mind, the present study is set out to explore stress factors among ab-initio pilots in the university. For this purpose, stressors were isolated and assessed by interviews with flight instructors. Then, the analytical hierarchy process (AHP) is applied to weigh those stressors among ab-initio pilots. A hierarchy was built with 3 criteria and 12 sub-criteria. Results showed that the most important criterion in stress among ab-initio pilots is personal factors, followed by organizational factors and environmental factors. Furthermore, the results revealed that the first four stressors within the global ranking were determined as the lack in body of knowledge, meteorological conditions, personality, and facilities and the fleet with the weights of 0.195, 0.154, 0.11 and 0.109. This work is unique due to its coverage of ab-initio pilots, and the results presented here may facilitate improvements in the evaluation of individual ab-initio pilots and the teaching environment for stress contributing factors.

(Vilnius Gediminas Technical University, 2023-11-23) Yilmaz Çetin, A.; Üçler, Çağlar; Professional Flight Program; ÜÇLER, Çağlar
Aviation is rapidly expanding and recovering from the pandemic impact driven by the experience economy. This is particularly subject to interfaces such as the aircraft seats, which are getting intense attention as a differentiator in the cabin. The focal point of this paper is to assess and convert customer requirements into what must be done for an optimum aircraft seat. To achieve this, a 2-step analytic hierarchy process and quality function deployment (AHP-QFD) methodology was successfully applied, consolidating product quality characteristics. Then, it leverages a novel scoring method of interdependencies to isolate dependable design variables. Consequently, safety, weight, and durability scored maximum, emphasizing backrest design and alternative composite materials, while test infrastructure was determined as a critical investment component. Furthermore, it is shown how AHP-QFD can be used for product strategy and strategic portfolio management of R&D projects.

(IOS Press, 2020) Buyukozkan, G.; Havle, Celal Alpay; Feyzioglu, O.; Gocer, F.; Professional Flight Program; HAVLE, Celal Alpay
Transportation becomes increasingly important for global trade, mobility, and economies. Passengers expect speed and quality from transportation services. As a result, the demand for air transportation is steadily rising. Higher demand for flights brings along new expectations and competition. In particular, airline companies are focused on service quality, knowing that it is a necessity to survive in a competitive market by meeting customer expectations. Hence, it is aimed that to analyze Airline Service Quality (ASQ) in Turkey. A SERVQUAL based model is developed and the criteria of the model is analyzed using group decision making (GDM) based intuitionistic fuzzy cognitive map (IFCM) approach. A real case is conducted in Turkey airline industry. By considering the hesitation, uncertainty and intuition of decision-making processes and the opinions of the decision makers, classical FCM approach is expanded to IF environment. Decision makers who are experts in Turkey airline industry, evaluate the relationship between the criteria. The importance ratings of the criteria are determined. Thanks to dynamic structure of IFCM, scenario analysis is performed to make strategic decisions. Originality of the paper is that it is the first study dealing with GDM based IFCM and SERVQUAL approach for ASQ in Turkey to the best of our knowledge.
