Operating aid, on the other hand, relates to covering all or part of the operating costs of an airport, defined as ‘the underlying costs of the provision of airport services, including categories such as costs of personnel, contracted services, communications, waste, energy, maintenance, rent, administration, etc., but excluding the capital costs, marketing support or any other incentives granted to airlines by the airport, and costs falling within a public policy remit’.
Il est permis d’en conclure que l’aide était nécessaire à la réalisation des investissements destinés à désengorger les infrastructures aéroportuaires et s’imposait compte tenu de l’obligation de respecter les prescriptions actuelles applicables aux infrastructures aéroportuaires modernes.
