4.2 Risk acceptance

Contextual description: Safety engineering activities will mitigate the risks associated with the operation of the RAS. Approving operation will require that the level of residual risk remaining following mitigation is accepted by the approving entities.

This objective requires the consideration of the further sub-objectives described below.

Practical guidance: Some regulatory regimes have very clear criteria for judging the acceptability of risk reduction (such as ALARP). In other cases a more ad-hoc justification for the acceptability of risk may be required.
