Student thesis: Master's Thesis


Runway safety is always the top issue around the world because of increases in air traffic volume in recent years The most fatal accidents associated with runways are called runway excursions A breakdown analysis of civil aviation accidents worldwide indicates that the occurrence rate of runway excursions is 22% which represents the largest factor among all categories (IATA 2015) Runway excursions tend to occur due to human errors especially pilot errors Identifying human risk factors associated with pilots in runway excursions will effectively reduce the severe threat of fatalities and losses caused by runway excursion accidents and incidents The purpose of this study is to examine significant human risk factors in runway excursions Based on the IATA RERR 2nd program we developed 70 human risk factors under a SHELLO model of six dimensions including liveware liveware to liveware liveware to organization liveware to software liveware to environment and liveware to hardware The fuzzy-set theory and Analytical Hierarchy Process (AHP) are applied to evaluate the importance of the risk human factors from the perspective of 145 Taiwan pilots and this study integrates aviation management level expert opinions about relative weighting and improvement-achievability in order to develop four kinds of priority risk management strategies for airline pilots to reduce runway excursions This empirical study of experts’ evaluation suggests that the most important dimension is the liveware as pilot’s core ability and the top ten significant risk factors are safety attitude situation awareness no-fault go-around policy ability to deal with contingency or emergency and operation deviation Meanwhile from the perspective of front-line pilots the most important risk factor is environment wet/ containment runways and weather issue rain/thunderstorm This paper contributes to aviation safety by developing a roadmap for the strategies of mitigating runway excursion with the risk factors ranked in order of importance thereby helping management authorities improve major operational and managerial weaknesses and also reduce the risks related to runway excursions
