Aviation is a complex system, and the investigation and modelling of aviation accident causation can suffer from being artificially manipulated into non-complex models and methods. This book addresses this issue by developing a new approach to investigating aviation accident causation through information networks, which centralise communication and the flow of information as key indicators of a system's health andrisk. The book's new model offers many potential developments and some key areas are studied in this research, maintaining firm focus on the overall health of a system.Abstract: The investigation and modelling of aviation accident causation is dominated by linear models. This book addresses this issue by developing a new approach to investigating aviation accident causationthrough information networks. It presents a new model that offers many potential developments and some key areas are studied in this research.
