(18)Since the objective of this Regulation, namely more homogeneous application of Community legislation with regard to the internal aviation market cannot be sufficiently achieved by the Member States because of the international character of air transport, and can therefore be better achieved at Community level, the Community may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty. In accordance with the principle of proportionality, as set out in that Article, this Regulation does not go beyond what is necessary in order to achieve that objective.
