Commission Regulation (EU) No 255/2010
of 25 March 2010
laying down common rules on air traffic flow management
(Text with EEA relevance)
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EC) No 551/2004 of the European Parliament and of the Council of 10 March 2004 on the organisation and the use of the airspace in the single European sky (the airspace Regulation)  and in particular Article 6(7) thereof,
(1) The Commission is required to lay down measures regarding air traffic flow management (hereinafter ATFM) with a view to optimising available capacity in the use of airspace and enhancing ATFM processes.
(2) The European Organisation for the Safety of Air Navigation (Eurocontrol) has been mandated in accordance with Article 8(1) of Regulation (EC) No 549/2004 of the European Parliament and of the Council of 10 March 2004 laying down the framework for the creation of the single European sky (the framework Regulation)  to develop implementing rules for ATFM. This Regulation is based on the resulting mandate report of 7 December 2007.
(3) The uniform application of specific rules and procedures within the airspace of the single European sky is critical for the achievement of the optimum use of available air traffic control capacity through the efficient management and operation of the ATFM function.
(4) This Regulation should not cover military operations and training as referred to in Article 1(2) of Regulation (EC) No 549/2004. However military aircraft operating as general air traffic should be subject to ATFM measures when operating or intending to operate within airspace or airports to which ATFM measures apply.
(5) In accordance with Article 13 of Regulation (EC) No 549/2004, Member States’ essential security or defence policy interests should be safeguarded in the definition and implementation of ATFM measures.
(6) A single central unit for ATFM in charge of planning, coordination and execution of ATFM measures has been established by Eurocontrol taking into consideration the recommendations of the International Civil Aviation Organisation (ICAO). Member States should be required to take the necessary measures to ensure that the central unit for ATFM optimises the overall effects of ATFM measures on the European air traffic management network (hereinafter EATMN).
(7) ATFM measures should be based on principles laid down by ICAO and all parties in the ATFM system should adhere to rules that ensure that air traffic control capacity is used safely and to the maximum extent possible.
(8) ATFM measures should take into account the availability of routes and airspace in particular through the application of the flexible use of airspace by all relevant parties including the airspace management cell laid down by Commission Regulation (EC) No 2150/2005 of 23 December 2005 laying down common rules for the flexible use of airspace .
(9) In order to optimise available capacity of the EATMN, including airports, procedures aimed at increasing the consistency between airport slots and flight plans should be established.
(10) It is appropriate to provide Member States and parties involved in ATFM processes with sufficient time to comply with requirements for air traffic flow management.
(11) The measures provided for in this Regulation are in accordance with the opinion of the Single Sky Committee,
HAS ADOPTED THIS REGULATION:
