2.4. Controlling interactions with other systems

Assurance objective: Identify how interactions between the RAS and other systems may give rise to unsafe behaviour.

Assurance objective: Manage interactions between the RAS and other systems to ensure they do not result in unsafe behaviour.

Contextual description: Although a RAS in itself may considered to be safe, it may still be possible for unsafe behaviour to emerge due to the interactions between the RAS and other systems. This may be interactions with another RAS, or with ‘manually’ controlled systems. Such interacting and collaborating systems are often referred to as a “System of Systems (SoS)”.  For many applications, RAS will operate as part of a larger SoS (although RAS will not always be part of a SoS, and not all SoS will contain an RAS). It is required to provide sufficient confidence that potentially unsafe interactions between the RAS and other systems have been identified and mitigated.
