Regulation (EC) No 551/2004 provides that the network functions shall aim at enhancing the overall performance of the ATM network and at supporting initiatives at national and functional airspace block level.

The tasks given to the Network Manager require a multiannual work programme and related budget, working arrangements between the Network Manager and the Deployment Manager, and ad hoc activities to identify safety risks at network level. Appropriate arrangements should therefore be made in this connection.

Strategic objectives of the Network Strategy Plan should be duly taken into account in the business plans from the operational stakeholders. The procedure for adopting this plan should also be clarified.

The Network Management Board should be advised on operational matters by the operational stakeholders' executive managers.

In order to be able to mitigate the impact of a network crisis, the European Aviation Crisis Coordination Cell (EACCC) should liaise with a network of State focal points and perform crisis exercises to anticipate a real time network crisis.

The budget of the Network Manager should be such that it allows the Network Manager to meet the targets identified in the performance scheme and to implement its work programme. The budget should be separately identifiable from the rest of the budget of the body appointed to act as the Network Manager where that body carries out any other activity.

Regulation (EU) No 677/2011 should therefore be amended accordingly.

The measures provided for in this Regulation are in accordance with the opinion of the Single Sky Committee established by Article 5 of Regulation (EC) No 549/2004,
