Module 2.5: Matching the Research Question to the Research Method Embry-riddle University Worldwide campus Dongwon, Shin ASCI 604 – Human Factors in the Aviation/Aerospace Industry Allen Boettcher Thursday, June 1, 2023 1
2 Research Problem Statement: The research problem statement in this study is focused on the effect of aircraft cockpit design on pilot fatigue. It highlights the potential issues and challenges faced by pilots due to the current cockpit design, particularly related to anthropometric dimensions and seat design. The problem statement suggests that the existing cockpit design may cause discomfort, pain, and fatigue, leading to a lack of concentration and potential safety risks during flights (Aminian, 2016). Effectiveness of the Problem Statement: The problem statement effectively communicates the research problem to the reader. It clearly states the specific focus of the study, which is the impact of cockpit design on pilot fatigue. It also highlights the potential mismatches between the current cockpit design and ergonomic design recommendations, indicating the importance of investigating and addressing these issues. Research Question or Hypotheses: The specific research question or hypotheses are not explicitly stated in the provided text. However, based on the information given, the following research question can be inferred: Research Question: What are the specific design issues and mismatches between the current aircraft cockpit design and ergonomic design recommendations concerning anthropometric dimensions and
3 seat design? How do these design issues and mismatches contribute to pilot fatigue, and what is their impact on pilot performance? This revised research question focuses on identifying the specific design problems and discrepancies between the current cockpit design and established ergonomic guidelines related to anthropometric dimensions and seat design. The aim is to investigate how these design issues and mismatches may contribute to pilot fatigue and examine their broader impact on pilot performance. By exploring these factors, the study seeks to enhance the understanding of the relationship between cockpit design and pilot fatigue, ultimately aiming to propose potential improvements or interventions to mitigate these issues. Research Design: The research design in this study is a survey-based usability evaluation. To assess the ergonomic problems related to cockpit design, a questionnaire with 90 questions was developed and distributed to pilots. The study primarily focuses on evaluating the pilot's seat design, and respondents are asked to rate various seat parameters using a numbering scale. The collected responses are then averaged to identify potential design problems in the cockpit. The research design aligns with the study's objective of evaluating the impact of cockpit design on pilot fatigue. By employing a survey methodology, data is directly obtained from the target population, which consists of pilots working international flight routes for different airlines. This approach allows for gathering feedback and ratings from a diverse
