Artikel 7

In order to prevent discriminatory practices and to assure equality of treatment, both contracting parties agree that:
1. User charges that may be imposed by the competent charging authorities or bodies of one Contracting Party on the designated airlines of the other Contracting Party shall be just, reasonable, nondiscriminatory, and equitably apportioned among categories of users. In any event, any such charge shall be assessed on the airlines of the other Contracting Party on terms not less favorable than the most favorable terms available to any other airline at the time the charges are assessed.
2. User charges imposed on the airlines of the other Contracting Party may reflect, but shall not exceed, an equitable portion of the full cost to the competent charging authorities or bodies of providing the appropriate airport, air navigation, airport environmental, and aviation security facilities and services, and in the case of airports, may provide for a reasonable rate of return on assets, after depreciation. Facilities and services for which charges are made shall be provided on an efficient basis. Reasonable notice shall be given prior to changes in user charges.
3. Each Contracting Party shall encourage consultations between the competent charging authorities or bodies in its territory and airlines using the services and facilities, and shall encourage the competent charging authorities or bodies and the airlines to exchange such information as may be necessary for an accurate review of the reasonableness of the charges in light of the principles of paragraphs (1) and (2) of this Article.
