Study of safety performance indicators and contributory factors aspart of an airline systemic safety risk data model

• Every airline would like to anticipate potential risks by allowing the organization to be both predictiveand proactive in its safety work. This is also mandated by regulators, such as ICAO, in the form ofrequirements for a safety management system. In order to successfully achieve this, a systemic view ofhuman factors, risks for both the organization and its operations are required. Relationships betweenincident outcomes and contributory factors needs to be further understood. This would involve theclassification of risk data, contributory factors for risk, data-handling from multiple risk data sourcesand the prudent use of safety performance indicators given the availability of existing tools to date.An earlier study (Rignér et al., 2009) proposed a methodology for airlines to explore ways of betterutilizing data already in their organization by the use of existing tools. This methodology includes thesteps of reviewing risk theory, the scope for human factors related to safety, safety performanceindicators, contributory factors and links between these as well as tools for collecting data. The purposeof this study is to apply, validate and further develop this methodology for airline operators as well asto develop a coherent model of systemic risk data management.One of the key issues here is to define the logic behind data management of existing, current andhistorical data and particularly how data can be combined to provide a prospective view of future risk.Without a clear strategy on how to do this, airlines may lose focus and revert to simply measuring whatis readily available, but potentially less meaningful.Research leading up to this development was performed within the HILAS (Human Integration into theLifecycle of Aviation Systems) project. The work has included field studies, work shops and interviewswith both front-line operators and management personnel within airlines. Information-sharing takesplace within the framework of the HILAS project. This research was conducted by a multidisciplinarygroup of human factors expertise: researchers, pilots, investigators and safety officers in an airline.
