ensure the development of a Community-wide aeronautical information infrastructure in the form of an electronic integrated briefing portal with unrestricted access to interested stakeholders. That infrastructure shall integrate access to and provision of required data elements such as, but not limited to aeronautical information, air traffic services reporting office (ARO) information, meteorological information and flow management information;

support the modernisation and harmonisation of the provision of aeronautical information in its broadest sense in close cooperation with Eurocontrol and the ICAO.

design of the European route network;

coordination of scarce resources within aviation frequency bands used by general air traffic, in particular radio frequencies as well as coordination of radar transponder codes.

The functions listed in the first subparagraph shall not involve the adoption of binding measures of a general scope or the exercise of political discretion. They shall take into account proposals established at national level and at the level of functional airspace blocks. They shall be performed in coordination with military authorities in accordance with agreed procedures concerning the flexible use of airspace.

The Commission may, after consultation of the Single Sky Committee and in conformity with the implementing rules referred to in paragraph 4, entrust to Eurocontrol, or another impartial and competent body, the tasks necessary for the execution of the functions listed in the first subparagraph. These tasks shall be executed in an impartial and cost-effective manner and performed on behalf on Member States and stakeholders. They shall be subject to appropriate governance, which recognises the separate accountabilities for service provision and regulation, taking into consideration the needs of the whole ATM network and with the full involvement of the airspace users and air navigation service providers.

the coordination and harmonisation of processes and procedures to enhance the efficiency of aeronautical frequency management including the development of principles and criteria;

the central function to coordinate the early identification and resolution of frequency needs in the bands allocated to European general air traffic to support the design and operation of European aviation network;

additional network functions as defined in the ATM Master Plan;

detailed arrangements for cooperative decision-making between the Member States, the air navigation service providers and the network management function for the tasks referred to in paragraph 2;

arrangements for consultation of the relevant stakeholders in the decision-making process both at national and European levels; and

within the radio spectrum allocated to general air traffic by the International Telecommunication Union, a division of tasks and responsibilities between the network management function and national frequency managers, ensuring that the national frequency management functions continue to perform those frequency assignments that have no impact on the network. For those cases which do have an impact on the network, the national frequency managers shall cooperate with those responsible for the network management function to optimise the use of frequencies.

flight planning;

use of available airspace capacity during all phases of flight, including slot assignment; and

use of routings by general air traffic, including:
