In a context characterized by rapid changes and strong economic and technological influences, safety remains the top priority in the aviation sector. Risk assessment and incident analysis are fundamental tools needed to improve Flight Safety, representing a central focus of multiple academic and industrial studies. The purpose of this thesis is to explore and expand the Functional Resonance Analysis Method (FRAM), an innovative methodology born to this end. By embracing the Safety-II philosophy, FRAM enables the analysis of complex non-linear socio-technical systems as well as the interactions within it, offering an integrated approach by complementing more traditional methods, which are, instead, based on a linear and proportional framework.
