  "text": "(a)An air traffic services provider shall determine the safety acceptability of a change to a functional system, based on the analysis of the risks posed by the introduction of the change, differentiated on basis of types of operations and stakeholder classes, as appropriate.\n(b)The safety acceptability of a change shall be assessed by using specific and verifiable safety criteria, where each criterion is expressed in terms of an explicit, quantitative level of safety risk or another measure that relates to safety risk.\n(c)An air traffic services provider shall ensure that the safety criteria:\n(1)are justified for the specific change, taking into account the type of change;\n(2)when fulfilled, predict that the functional system after the change will be as safe as it was before the change or the air traffic services provider shall provide an argument justifying that:\n(i)any temporary reduction in safety will be offset by future improvement in safety; or\n(ii)any permanent reduction in safety has other beneficial consequences;\n(3)when taken collectively, ensure that the change does not create an unacceptable risk to the safety of the service;\n(4)support the improvement of safety whenever reasonably practicable.",
