4.3 Provision of sufficient confidence in the required behaviour

Contextual description: The assurance objectives (areas 1 through 3) set out how the assurance of an RAS may be demonstrated. The level of confidence with which the objectives are demonstrated will vary depending upon the assurance activities undertaken and the nature and amount of evidence that is provided. The confidence provided must be sufficient to enable a defensible decision to be made on allowing the operation of the RAS.

The judgement on what level of confidence is required against the objectives is subjective. For some domains, guidance on making such judgements may be available through standards and other guidance documents. For other domains judgements may need to made on a case-by-case basis using a risk-based approach (as considered in 4.2 Risk acceptance).

Practical guidance:  To be determined.
