安全是航空運輸最重要之環節。隨著飛航操作相關研究越來越成熟,專家學者也越來越重視機坪地勤的安全問題。國際飛航安全基金會統計指出,機坪事件每年對航空業所造成的直接損失大約將近50億美元,而其中尚不包含許多間接之成本。而「人」無疑是機坪勤務作業中最重要的一環,關於造成機坪事件的許多研究皆指出,作業程序之疏失乃是最大之因素。本研究援引人為因素SHELLO分類模式為架構,提出機坪勤務人員風險因素,以發放5分專家問卷篩選出在各構面下之重要風險因子,同時對各構面風險因子進行改善程度問卷調查發放對象為民航局之行政主管及地勤公司主管,共發出7份問卷,問卷使用口語綜合評判函數進行統計,此方法可以減少數值間之轉換並讓專家在填答問卷時可以較容易作答。研究結果發現對於SHELLO模式裡,「組織」構面在人為因素裡扮演著第二重要的角色。而在結果中發現,機坪勤務專家之風險因素重要程度與民航局官員之優先改善順序上產生落差,發現在現今所存在之風險因素的改善上確實有不易改善的困難,此一研究結果可供民航局及地勤業者作為參考,以降低機坪地勤風險發生之機率。
Safety is the most important issue for aviation industry. Along with the progress in aviation researches, scholars and professionals are becoming more concerned about the problems to Ramp Safety. According to the Foundation of International Aviation Safety’s preliminary report, ramp accidents directly cause the loss of 5 billion dollars annually to aviation industry. This is an intentional act to prevent personal failure of operation procedures and ramp ground staffs are the most significant factor. This study focused on the risk factors of ramp operators, using the SHELLO framework. First, five questionnaires for experts were distributed to identify the important risk factors in various domains and modify those risk statements. Next, modified questionnaires were sent to mangers of the Aviation Bureau and Airport Service Companies. The findings suggested that in SHELLO model, organization domain is considered as the second important role among those personal factors. Moreover, the findings pointed out that the differences existed between mangers of the Aviation Bureau and managers of Airport Service Companies. Overall, the findings suggest the researchers of the aviation industry need to do much more to improve the safety procedures and reduce the risk possibility of ramp operation.
