The Simulation Algorithm Design of the Safety Margin for an Aircraft Accident

An aircraft accident decision is studied under the view of system safety, with the simulation for the overrun speed and time if it rejected takeoff (RTO), and the consequence would be slighter, saving many lives. It is believed in this paper that continuing to climb when catching fire is the worst decision with the heaviest lost in lives. The simulation algorithm is compiled to compute the overrun speed and time at the end of runway to evaluate the safety margin after RTO at high running speed. Its result also shows that the 90 second rule for evacuating is a key element to obey to make decision, having higher order constrain than V1. A few events are discussed to verify the safety margin.
