[Context and motivation]
In air traffic management (ATM) safety assessments are performed with traditional techniques such as failure mode and effect analysis (FMEA).
[Question/problem]
As system modelling is becoming an increasingly important part of developing ATM systems, techniques that integrate safety aspects and modelling are needed.
[Principal ideas/results]
This paper proposes an approach for thorough failure analysis of ATM systems that consist of several interacting components and similar systems. The new technique is called failure sequence diagrams (FSD) and supports FMEA in modelling failures and their effects through interactions between system components. FSD has been used in a case study by safety and system engineers in three different ways.
[Contribution]
The study suggests that FSD was easy to use and supported FMEA well, but did not cover its weakness in analysing multiple failures.
