13 X-NOISE 2015 Assessment of Progress towards the dB target Conclusions & Recommendations A typical 2.5 db additional benefit relative to the 5dB already consolidated at TRL 6 by 2010 can be expected from Generation 2 Noise Reduction Technologies, provided such solutions mature to TRL6 in time for Relative to the ACARE noise target of -10dB per operation, the aircraft noise research effort can be considered as generally on track It will still require significant support in remaining years before 2020: Success Conditions Bring the most promising Generation 2 noise reduction technology totrl6, through an appropriate full scale validation effort Very significantly increase the effort dedicated to Low Noise Aircraft configurations Consolidate wider implementation of low noise operational procedures

14 X-NOISE 2015 Assessment of Progress towards the 2050 target Recommendation for Future Steps Considering evidence of increased sensitivity to noise in local communities impacted by aviation operations,, it is essential that a greatly expanded effort is launched at the earliest opportunity to address the key aspects of noise effects and impacts and ultimately support the implementation of successful policies complementing the technological achievements expected to be realised. A strongly coordinated and integrated approach would definitely provide a significant added value, bringing together to address a common goal the wide range of expertise needed across the board of solutions, from technology enablers to understanding impacts.

18 ANIMA: Objectives of Global Coordination Workpackage WP activity will aim at enhancing coherence and efficiency of noise research in Europe, ensuring and reinforcing coordination between national, international WP activity will aim at enhancing coherence and efficiency of noise and research EU in research Europe, ensuring activities. and reinforcing To this coordination end, it will: between national, international and EU research activities. To this end, it will: Establish and update through a scenario based approach a common strategic research roadmap for aviation noise reduction, addressing the development of new technologies and methodologies Coordinate a European wide network of experts and research actors in support of the roadmap process, stimulating the emergence of novel approaches to overcome gaps, ensuring minimal duplication and fragmentation in the course of future research efforts. Explore possibilities, facilitate and establish practical conditions for targeted international collaboration in line with the strategy for EU international cooperation in research and innovation as well as the needs put forward by the strategic roadmap for aviation noise, including aspects related to international regulatory discussions. Develop and assess the roadmap based on enhanced set of criteria including impacts driven targets Maintain dynamics of past networking efforts, provide a comprehensive vision of national efforts Identify and recommend cooperation topics based on well focused shared interests
