Safety Risk Assessment of Human-Machine Interaction Behavior in Cockpit

Safety risk assessment is of significant importance in aviation safety management. Timely and binding hazard identification and risk assessment makes great contribution to the prevention of accidents. Aiming at the human-machine interaction behavior risk in cockpit, the interaction behavior risk assessment process is provided in accordance with the general process of risk assessment. The hazard of interaction behavior is identified using event tree analysis (ETA), and the risk assessment model is developed based on human-in-the-loop fault tree analysis (HIL-FTA), and risk level is determined using risk matrix based on severity and probability. Finally, an application instance is provided to illustrate the effectiveness of the safety risk assessment method.
