Özet:

In aviation, the majority of accidents are caused by pilots' poor decision-making behavior and judicial incompetence. Understanding the decision behavior of pilots will contribute to the improvement of decision processes and their judgments against events. It is known that traditional decision making models are not valid in all contexts, especially rational processes ignore many factors. These factors that especially important in pilots' decision processes are time pressure, experience, coordination, contextual complexity, constantly changing conditions, incomplete and unreliable information. It is seen that the model that explains the decision process in the context of these factors is the Naturalistic Decision Making (NDM) model in the literature. In this context, the aim of the study is to understand whether the decision-making behavior of pilots is appropriate for NDM processes and to reveal its relationship with other decision processes defined in the literature. Concurrent mix method pattern that is considered to be the most suitable for the purpose of the research, was used. In this design, quantitative and qualitative data were collected at the same time, qualitative data were analyzed with NVivo11 and quantitative data was analyzed with SPSS24 programs. The study group from which qualitative data is obtained consists of 12 pilots who are the first and second captains selected by purposeful sampling method. Qualitative data were obtained as a result of a semi-structured interview. The sample group of the quantitative data consists of 223 pilots working in 3 different airline companies in Istanbul. In the sampling method of the research, the simple random sampling method was used. NDM scale developed by Sundu and Yaşar (2020) and Decision Making Styles scale developed by Scott and Bruce (1995) and adapted to Turkish by Taşdelen (2001) were used as a measurement tool. As a result of the analysis of qualitative data; Six themes were obtained, namely the source of information, factors affecting the decision, the right decision and its criteria, the structure of the decision situation, how the decision was made, and sources of stress. The themes emphasize that pilots behave in accordance with the NDM model, using their experience as a source of information and their intuition in decision-making processes. As a result of the quantitative analysis; It has been observed that the decision processes of pilots adopt NDM processes rather than rational processes, and NDM is positively associated with intuitive decision making. As a result of the findings, suggestions were made for researchers, practitioners, educators.
