The Effectiveness of Operational Residual Risk Assessment: The Case of General Aviation Organizations in Enhancing Flight Safety in Alignment with Sustainability

Abstract

Operational risk management (ORM) is crucial for every aviation organization. The assessment of operational risk (OR) is a critical area of study, as organizations must continuously evaluate and mitigate potential risks to maintain high levels of performance and safety. The motivation for writing this paper was to address the cognitive gap identified through literature analysis. The aim of this paper is to assess the effectiveness of operational residual risk assessment in general aviation (GA) organizations, with a specific focus on its role within the decision-making process to enhance flight safety in line with sustainability. By addressing a cognitive gap identified in the literature, this study seeks to determine whether current risk management practices adequately assess and mitigate residual risks, especially in organizations where operational risk is inherently high. Based on a literature review, the authors present adopted concepts of ORM and OR. The survey methodology involved a questionnaire on OR assessment, consisting of 32 questions completed by respondents twice—before and after 63 series of flights. The survey was carried out across two groups with significantly varying levels of flying experience (students and instructor pilots), with a particular focus on the influence of human factors. The conclusions are based on a comparative analysis of the difference in the results obtained after and before the series of flights in both surveyed groups. The survey was conducted in three selected general aviation organizations in Poland using nonprobability convenience sampling. The results demonstrate an overall significant underestimation of OR in both student and instructor groups. Therefore, it can be concluded that operational risk assessment in the selected organizations was not sufficiently effective. Additionally, it was shown that staff experience affected the effectiveness of OR assessment. Moreover, this study identified specific aspects of operational risk that were most underestimated. By addressing the cognitive gap, this study enhances both the theoretical and practical understanding of residual risk management, particularly in relation to safety and efficient resource use in aviation. It also offers the Operational Residual Risk Underestimation Index (ORRUI) as an actionable parameter developed to quantify and standardize the level of underestimation of operational residual risks in civil aviation.
