State of Harmonisation Document

The purpose of this document is to provide a high-level summary of the current state of progress toward achieving the necessary level of interoperability between the Next Generation Air Transportation System (NextGen) and the Single European Sky ATM Research Programme (SESAR), based on the cooperative activities between the United States and the European Union. The U.S. and EU collaboration aims to harmonise and secure Air Traffic Management (ATM) modernisation efforts as drivers of and in support of the International Civil Aviation Organisation (ICAO) Global Air Navigation Plan (GANP) with the Aviation System Block Upgrade (ASBU) programme. Both NextGen and SESAR recognise the need to integrate the air and ground parts of their air traffic management systems by addressing efficiency needs of flight trajectories planning and execution and the seamless sharing of accurate information. The U.S./EU joint harmonisation work will assure that modernisation and advances in air navigation systems worldwide can be made in a way that supports cooperation, clear communication, seamless operations, and optimally safe practices. The collaborative harmonisation work between the U.S. and the EU has taken place under the Memorandum of Cooperation (MOC) between the United States of America and the European Union on Civil Aviation Research and Development that was signed in March 2011, and specifically under Annex I, which covers “SESAR-NextGen Cooperation for Global Interoperability.” The two parties have concluded that it is more effective to plan for harmonisation activities with an implementation focus (ref. NextGen Implementation Plan and the European ATM Master Plan) and to initiate the activities early in the research and development phase. The MOC and its Annex I provide the functional framework for collaboration on such harmonisation activities. This framework also provides a vehicle for the U.S. and Europe to work together towards interoperable standards and in support of efforts towards achievement of ICAO global harmonisation as articulated in the ICAO GANP/ASBU´s. Much of the collaboration work done under this framework directly supports global ICAO standardisation efforts. The U.S. and Europe are for the same reason also supporting and engaging in initiatives fostered by other international bodies, such as the industry standardisation bodies of Radio Technical Commission for Aeronautics (RTCA) and European Organisation for Civil Aviation Equipment (EUROCAE). There are five main areas of collaboration under Annex 1 to the MOC on NextGen and SESAR Harmonisation: Transversal Activities; Information Management; Trajectory Management; Communication, Navigation, and Surveillance (CNS) and Airborne Interoperability; and Collaboration Projects. This State of Harmonisation Document summarises the progress made in these five areas.
