Abstract

In order to solve problems of existing safety assessment methods of civil airborne system, such as unclear logical reasoning and poor readability, firstly, an argument strategy for its safety assessment, based on safety case and GSN language, was studied and proposed through analyzing compliance verification approach to system safety requirements. Secondly, system safety argument was conducted separately from two aspects of safety goal satisfaction and safety requirements management. Finally, effectiveness of this safety case based assessment method was demonstrated with real cases. The results show that safety case based on GSN meets requirements of civil aircraft and system development, and given the clear logical relationship it builds between safety objectives and supporting evidences, it can be used for internal communication and airworthiness certification. © 2019 China Safety Science Journal.
