The cost-effectiveness of envisaged noise-related operating restrictions will be assessed taking due account of the following elements, to the extent possible, in quantifiable terms:
the anticipated noise benefit of the envisaged measures, now and in the future;
the safety of aviation operations, including third-party risks;
the capacity of the airport;
any effects on the European aviation network.
In addition, competent authorities may take due account of the following factors:
the health and safety of local residents living in the vicinity of the airport;
environmental sustainability, including interdependencies between noise and emissions;
any direct, indirect or catalytic employment and economic effects.
