10 Technology and Operations Goals 10

11 Goals Setting in CAEP NOx Reduction Technologies (2006, 2009) Noise Reduction Technologies (2008) Environmental Benefits from Operational Initiatives (2010) Fuel Burn Reduction Technologies (2010) 11

12 Goals Setting in CAEP Independent Experts Panels Broad representation Common Assumptions Baselines Manageable number Aircraft Categories Independent Realization Factors 12

13 Technology and Operations Goals Balance environmental benefit with technological feasibility, economic viability, and do not adversely impact other environmental factors Provide stretch targets for industry R&D to aim at in cooperation with States Purpos se ciples Prin Use the same metric as certification to enable direct comparison Technology Goals based on Current TRL < 8 technologies that will be TRL>8 at a given time Technology availability with at least one manufacturer Technology availability specific to the seat class considered 13

14 ICAO Technology Goals for NOx Mid Term (2016) 45% ±2.5% below OPR 30 Long Term (2026) 60% ±5.0% below OPR 30 Ref: Independent Experts NOx Review and the Establishment of Medium and Long Term Technology Goals for NOx (ICAO Doc 9887),

15 ICAO Technology Goals for Noise Cumulative EPNL re: Chapter 4 Limits at TRL8 Aircraft Category Mid Term (2018) Long Term (2028) Regional Jet 13.0± ±5.5 Twin 21.0± ±5.5 Long Range Twin 20.5± ±5.5 Long Range Quad 21.0± ±5.5 Medium Term (2018) Cumulative Noise Goals Long Term (2028) Cumulative Noise Goals 310 Chapter 4 Limit LR4 310 Chapter 4 Limit LR4 Cumulative Noise Lev vel, EPNdB Mid-Term Goal Mid-term Upper Bound Mid-term Lower Bound RJ SMR2 LR2 Cumulative Noise Lev vel, EPNdB Long-Term Goal Long-Term Upper Bound Long-Term Lower Bound RJ SMR2 LR Max. Takeoff Mass (Tonnes) Ref: Independent Experts Noise Review and the Establishment of Medium and Long Term Technology Goals for Noise, Max. Takeoff Mass (Tonnes) 15

16 ICAO Technology Goals for Fuel Burn Fuel Burn Reduction Technology Workshop (25 to 26 March 2009) Survey of stakeholders khld in Review (25 27 ordering new May 2010) aircraft Report establishing Goals (2011) A wish for more fuel efficient efficient aircraft versions seems to be overtaking the traditional emphasis of keeping maximum commonality across fleets Concern about likely increased costs of new technology and possible changes in infrastructure 16

17 Independent Expert Led Reviews for Technologies Operational Initiatives The global civil ATM system goal is to achieve an average of 95% operational efficiency by 2026* Agreement to continue this effort during the CAEP/9 * The goal has a lot of caveats associated with it and should not be used in isolation 17
