The research endeavors, via the analysis of local flight safety records, in identifying flight safety risk factors that might induce high adverse safety impact. This study also tries to locate the discrepancy, if any, between the derived outcome and the safety cognition that feedback from aviation industry. Variation among separate aviation liners in relevant regards are also studied and analyzed. Upon above, conclusion and suggestion then follows. As the beginning, some risk matrix model analysis is performed in accordance with the flight safety records that input from five Taiwanese air carriers in recent years, so as to identify the high risk safety factors. Next, this study undertakes various un-paired independent sample t tests on both severity and frequency of the derived safety factors through the above-mentioned risk matrix analysis and their counterparts as perceived by both high-level supervisors and/or employees of aviation industry. The result reveals that both high-level supervisors and the employees of aviation industry are inclined to be conservative and conscientious when confronting safety issues. In addition, this study further utilizes ANOVA analysis to investigate the discrepancy between the derived high risk safety factors and that perceived by managerial level and their underling for each individual aviation operator. Comparisons of perceived risk indicators among separate airlines are also conducted. The result validates the hypothesis that significant difference prevails regarding the perceived risk indicators among aviation operators. Besides, for each operator there is still some divergence between the perceived and derived risk indicators. Nevertheless, no obvious difference can be identified among different routes. (International vs. domestic) By end of this study, some conclusion, recommendation and the likely countermeasure are thereby proposed.
