Neutral Safety Taxonomy Utilization at Air Transport Operator

Despite recent improvements in air transport safety, the types of incidents that were considered suppressed by previous corrective measures continue to recur in commercial aircraft operations. The question therefore arises whether enhanced data procession could be the next step forward. Today's commonly used approach to safety management relies primarily on the identification and mitigation of the so-called root cause, the suppression of which is intended to prevent the occurrence of negative phenomena. However, in accordance with the latest safety methods, it can be assumed that it is not enough to deal with negative data alone to understand the occurrence causality and implement meaningful mitigation measures. This research therefore builds on the principles of Safety II and aims to design and present an event classification scheme based on neutral taxonomy that deals with factors influencing events in both positive and negative contexts. This could then enable an easier comparison of events that are often investigated individually and thus bring greater insight into flight operations. The presented approach aims to name not only the weaknesses but also the strengths of airline's system. These could later serve as a basis when setting internal processes, simulator trainings or designing both normal and abnormal operating procedures.
