Commission Implementing Regulation (EU) No 1079/2012
of 16 November 2012
laying down requirements for voice channels spacing for the single European sky
(Text with EEA relevance)
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Whereas:
Specific provisions of Regulation (EC) No 1265/2007, mainly regarding procedures, were already applicable in the airspace below FL 195.
Previous conversions to 8,33 kHz channel spacing above FL 195 have reduced frequency congestion, but have not eliminated it. Many Member States find it increasingly difficult to satisfy the demand for new frequency assignments in the aeronautical mobile route service band 117,975-137 MHz (‘the VHF band’).
The only realistic option to resolve the medium to long-term congestion problem in the VHF band is the further deployment of air-ground voice communications based on 8,33 kHz channel spacing.
Inability to meet future demand for frequency assignments will delay or make impossible airspace improvements to increase capacity and will lead to increase in delays entailing significant costs.
Harmonised frequency use in the entire European airspace under Member States responsibility for specific applications will further optimise the use of limited radio spectrum resources. Therefore the 8,33 kHz channel spacing conversion of frequencies should take into account the possible actions of the Network Manager for harmonised frequency use mainly by general aviation for air-to-air communications purposes and for specific applications related to general aviation activities.
The investment made as a result of Regulation (EC) No 1265/2007 has substantially reduced the cost of deployment of 8,33 kHz channel spacing in the airspace below FL 195 for air navigation service providers and for operators flying above FL 195.
The requirements for general aviation aircraft operating under visual flight rules to be equipped with radios with 8,33 kHz channel spacing capability will impose a considerable cost with limited operational benefits for those aircraft.
The European Organisation for Civil Aviation Equipment (Eurocae) specification ED-23B should be considered as sufficient means of compliance with regard to the capabilities of the airborne equipment.
Airborne equipment compliant with the Eurocae specification ED-23C provides improved communications characteristics. It should therefore be considered as the preferred option to ED-23B whenever possible.
The arrangements for State aircraft should take into account their specific constraints with appropriate implementation dates.
This Regulation should not cover military operations and training in accordance with Article 1(2) of Regulation (EC) No 549/2004.
Member States which apply North Atlantic Treaty Organisation (‘NATO’) combined frequency requirements should maintain the 122,1 MHz frequency in 25 kHz channel spacing for the accommodation of State aircraft not equipped with radios with 8,33 kHz channel spacing capability, until a suitable alternative is found.
With a view to maintaining or enhancing existing safety levels of operations, Member States should ensure that the parties concerned carry out a safety assessment including hazard identification, risk assessment and mitigation processes. Harmonised implementation of those processes to the systems covered by this Regulation necessitates the identification of specific safety requirements for all interoperability and performance requirements.
In accordance with Regulation (EC) No 552/2004, implementing rules for interoperability should describe the specific conformity assessment procedures to be used to assess the conformity or suitability for use of constituents as well as the verification of systems.
For reasons of clarity, Regulation (EC) No 1265/2007 should be repealed.
The measures provided for in this Regulation are in accordance with the opinion of the Single Sky Committee,
HAS ADOPTED THIS REGULATION:
