Study on Evaluation of Airline Pilot's Flight Violation Behaviors and Psychological Risk

摘要

This study aimed to evaluate the flight violation behaviors of airline pilots and examine the relationship between violation behavior and risk psychology based on Quick Access Recorder (QAR) data and surveys. Flight violation evaluation indexes were selected from airlines' Flight Operations Quality Assurance (FOQA) items. Then, an evaluation standard for violation behaviors was determined by investigating airlines, and a violation evaluation model for pilots was established. To examine the model's reasonableness and explore the relationship between violation behavior and risk psychology, flight QAR data were analyzed, and pilot's risk psychology characteristics were investigated by using psychological scales. In the case study, correlation analysis showed that landing vertical overload—a key factor in landing safety—was significantly negatively correlated with risk tolerance and significantly positively correlated with risk perception. Significant correlations among the violation indexes indicated interrelationships among the violation behaviors. This evaluation method can be applied to airlines' FOQA to effectively and efficiently identify and control pilot's violation behaviors. These findings are expected to provide a support for improving aviation safety.
