Flight Safety Assessment and Management during Takeoff

The goal of a safety management system is to monitor sensors, identify hazards and mitigate risk to the extent possible. In this paper, we present a novel approach called Flight Safety Assessment and Management (FSAM) to assess key quantitative and qualitative feedback parameters for loss of control (LOC) risk. Decision making logic is specified as a set of hierarchical timed automata models. Logic is customized to phase of flight as well as the control authority and modes. States are classified as nominal, moderate risk and high risk, enabling FSAM to issue warnings and override actions as necessary. FSAM logic for the takeoff phase of flight is presented in this paper.
