Terminal costs are those related to the provision of the following services:
- airport control services, airport flight information services including air traffic advisory services, and alerting services,
- air traffic services related to the approach and departure of aircraft within a certain distance of an airport on the basis of operational requirements,
- an appropriate allocation of all other air navigation services components, reflecting a proportionate attribution between en-route and terminal services.
The costs of terminal services are financed by means of terminal charges imposed on the users of air navigation services and/or other revenues, including cross-subsidies in accordance with Community law.
