Abstract [en]

Airlines measure safety performance to understand the state of the operations. Much datais collected but it is far from obvious how to handle all the data, act on the result or evento know what can be measured in a meaningful way. The overall purpose of this study isto propose a method for airlines regarding how to evaluate and improve their currentpractices related to safety performance monitoring and measurement.Mandatory and voluntary reporting systems capture aspects of the operations but arelargely retrospective and do not by themselves provide a predictive safety performancemonitoring capability. Flight data monitoring programs and other data sources can add apredictive capability. It is of great importance to understand what data to look for and tounderstand the relationships between various pieces of data to be able to improve in thename of safety. There is also a great need for practical guidance on how to develop amore predictive safety management.Human factors is the field believed to have most potential to substantially improve safety.In recent research an approach to airline safety management describes the organisationalprocesses in layers of real-time operational cycles, real-time operations support, tacticaland strategic organisational processes. When a systemic view on human factors,including individual, technical and organisational aspects, is applied to this organisationalstructure it forms a matrix for strategic risk data that may be used in development of acomprehensive safety parameter scope.It is believed that the currently dominant safety model approach with the discussion ofcausality and of latent conditions as root cause or causes still has potential to improvesafety due to the existing gap between theory and practice. It is, however, a greatchallenge to bridge this gap. In this research a five-step methodology is proposed tosystematically review; 1) currently known safety performance indicators directly relatedto safety, 2) contributory factors identified in reports, 3) other contributory factors withvalidated relationship to safety and 4) links between on the one hand the selected safetyperformance indicators and identified contributory factors and on the other handcontributory factors linked to other validated sources such as human factors theory. Withthis revision at hand and 5) using all available data sources it will be more feasible tojustify current safety activities and the relevance of data collected. This method is also2believed to identify feasible areas of improvements and contribute to balancing resourcerequirements in relation to the safety benefits coming out of the safety program.
