Assessment of Flight Crew Errors Based on THERP

The purpose of this study is to reduce the aviation accidents and incidents induced by flight crew errors. A flight crew errors analysis and classification system is developed preliminary. In combination with aviation flight accidents exploration, and interviews with pilots, the human error modes which will occur in the flight task are identified. A quantitative method to assess flight crew errors is established on Technique For Human Error Rate Prediction (THERP). In a case study, the takeoff task is analyzed, the human error modes and consequences are identified, and the failure probability of takeoff task is calculated. Those results are useful for SSA (System Safety Assessment) to improve the aircraft safety design.
