Elaboration of Safety Requirements


Publication Type:

Conference/Workshop Paper


32nd Digital Avionics Systems Conference


According to the aircraft standard ARP4754A, requirements should be carefully traced and validated. A systematic methodology for safety requirements elaboration (refinement/decomposition as well as allocation management) is lacking. To overcome this lack, an ARP-aligned and DOORS implementable approach called RAP (Requirements Allocation Process) is proposed. RAP offers a textual as well as graphical means for managing safety requirements. Besides supporting requirements decomposition and allocation, RAP also supports design decisions. The usefulness of RAP is illustrated by an example, applying the approach to a High Lift System.
