WITNESSING THE COMPLIANCE ACTIVITIES — STATEMENT OF COMPLIANCE The ATM/ANS provider will, when demonstrating the compliance of the ATM/ANS equipment with applicable requirements, such as user or safety requirements, allow the competent authority, if so requested, to participate in any compliance activity concerning the demonstration of compliance of the ATM/ANS equipment in the final or suitably mature design configuration. These demonstrations are necessary to determine that the product has no feature or characteristic that renders the ATM/ANS equipment unsafe for the intended use. Competent authority participation will increase confidence on the evidence presented as part of the SoC and facilitate its efforts to review the associated changes to the functional system. Such participation is in any case guaranteed by ATM/ANS.OR.A.050.
