ABSTRACT

Professional knowledge and relevant experience are required in different levels of events though aircraft accident rarely occur. Based on the characteristics of civil aviation emergencies, this paper constructs an aircraft accident scenario construction factor model based on four elements: causing subject, bearing subject, fighting subject and system state. It also studies the structural expression and storage of aircraft accident case base based on the frame representation. The paper takes the 2019 Ethiopian Airlines air crash as an example, the case base storage model is established. The analysis results verify the rationality and feasibility of the model in the construction of the aircraft accident case base. This model helps to standardize aircraft accident case bases and lays the foundation for improving emergency command and decision-making levels.
