2.5 Controlling interactions at the system-level

Assurance objective: Identify how interactions between elements of the RAS architecture may give rise to unsafe behaviour.

Assurance objective: Manage interactions between elements of the RAS architecture to ensure they do not result in unsafe behaviour.

Contextual description: Although the individual between elements of the RAS architecture may meet their requirements, it may still be possible for unsafe behaviour to emerge due to the interactions between those elements. It is therefore required to provide sufficient confidence that potentially unsafe interactions between elements have been identified and mitigated.

Practical guidance: As part of addressing these objectives, the impact of limitations of one element of the architecture on the behaviour of another must be considered, for example design decisions taken on how to implement sensing may impact on the performance that is achieved by functions such as object classification.
