ABSTRACT
Introduction The European Air Traffic Management system undergoes a dramatic adoption in the next couple of years. Until the year 2020 doubling of traffic, increased automation and increased autonomous operation of aircrafts, and considerable changes of the airspace structure is to be expected. In order to provide a still safe system in this situation, several concerted activities are initiated which are bound into the European Safety Regulatory Requirements (ESARR) framework. As part of the ESARR framework, quantitative safety assessment of a planned system change needs to be conducted, which addresses technological, procedural and human contributions to safety performance. However, the power of quantitative risk assessment is depending on the power of the risk assessment methods used. Regarding human reliability old fashioned methods are often used which predetermine misleading safety improvements as they result from a systematic mis-assessment of the human contribution to risk and safety. The resilience principles are used to define a better approach to Human Reliability Assessment (HRA). Note that the chapter does not propose to merge human reliability and resilience but to apply the resilience principles to inclusion of HRA into safety assessments.
