Flight Safety Performance Assessment Based On The Route Driving Behavior

With the development of the economical globalization, Chinese air transport industry has entered to a sustained and rapid development track. However, when people is in the sharing of economic benefits and the convenient traffic, aviation safety has become a focus common concerned by all countries in the world. To ensure the security, people have to control the safety during of the operation. Therefore, safety performance appraisal is a key link in the safety control. Traditional safety performance was based on the accidents and incident rate. Flight accident and incident rate was too extensive, which was influenced by the external occasional factor. It couldn't objectively reflect the real security situation in different airlines. People couldn't capture some potential human errors caused accidents or incidents and couldn't analysis these error chains. To this end, this study has put forward the concept of driving behavior standardized as the criterion of safety performance. Modern airline driving behavior included technical skills and non-technical skills which were an important guarantee for the flight safety. The attention on research is to explore these multidimensional-criterion components of technical skills and technical skills, and also explore how these multidimensional-criterions influence the flight safety.Multidimensional scale was developed through overviews of former studies, open-ended interview and counseling of experts on the base of CRM and TEM, which consisted scale to technical skills and non- technical skills of 27 classical behavioral items that can affect airline safety. Data was collected from a sample of 118 pilots from China Southern Airlines Ltd. The criterion variances of scale came from the performance of 86 pilots in airlines. Confirmatory Factor Analysis and Hierarchical Regression Analyses showed: first, Measurement of technical skills had high validity and reliability in four flight phases, which was comprised of Pitch Control, Yaw Control, Trim-ability and Spend Control. Second, measurement of non-technical skills had high validity and reliability in four flight phases, which was comprised of Automation Awareness, Leadership and Management, Situation Awareness and Decision Making and Interpersonal Cooperation. Third, multidimensional scale had high predictive validity in four flight phases. Fourth, Measurement of technical skills and non- technical skills was a scientific and effective evaluation tools for the flight safety performance.The study of handling behavior-based aviation safety performance appraisal is a deeper understanding in the fields of aviation psychology and organizational behavior. Multidimensional criterion scale would be not only to improving safety management in airlines and standardizing driving behaviors, but also for the airlines pilot selection, the diagnosis of the problematical flying behaviors and human factor training to provide a scientific and effective evaluation tools.
