1. NOISE ABATEMENT A COMMERCIAL AVIATION PERSECTIVE Andy Vasarins Vice President Flight Operations Air Transport Association of Canada September 16, 2007 I CAO-McGill University Institute of Air and Space Law Aviation Safety, Security & The Environment: The way Forward Conference Montreal, Québec

2. Presentation Outline ATAC – Who We Are How It All Started ? Commercial Aviation In The 60’s & 70’s What Has Changed ? Where To From Here ?

3. Who We Are Trade Organization, established in 1934 representing the interests of Canada’s airlines – global, national, charter, regional/local Vigorously advocate commercial aviation interests in Ottawa Work with regulators to enhance safety, reduce the financial impact of regulations. Other members include industry suppliers and foreign carriers doing business in Canada ATAC is the voice of the industry – represents over 95% of commercial air transport revenues in Canada

4. Always In Spotlight

6. How It All Started Traffic Growth and Route Expansion Larger Aircraft Turbo Jets and Low Bypass Turbo Fans Airport Expansion Noise Mitigation Programs Hush Kits

11. What Causes Noise Engines »Low Bypass Turbofans »Turbo Jets »Propeller Driven Airframe Design Climb Out Landing Reverse Thrust Taxiing Engine Testing

14. What Has Changed Engine Types – High Bypass Turbofans New Composite Materials » Lighter »Quieter Twin Engine Aircraft New Aerodynamic Shapes RNAV Sid Departures Noise Abatement Procedures »No Reverse on Landing »NADP Departures NEF Recommendations Land Scarcity

15. Schematic turbofan engines; the high-bypass engine (lower) has a large fan that routes much air around the turbine, the low-bypass engine (upper) has a smaller fan routing more air into the turbine.

18. Noise Abatement Woes 40 Years Old Do Not Reflect Today’s Technologic Reality Costly Cause Noise Pollution Burn up Precious Resources

23. Where to From Here

24. NEF Contour Enforcement

25. Government Role The Issue Jet aircraft are one of the most disturbing sources of noise in our environment. People who live in communities near airports have become increasingly concerned about potential health effects from aircraft noise.

26. Airports Role »Proactive Communication »Airport Design »Taylor NADP Departures ANS Role »Collaborate with Airlines »RNAV SIDS »Constant Descent Approaches

27. AVIATION TRANSPORTATION IS AN ESSENTIAL REQUIREMENT OF GLOBAL ECONOMICS 9 – 11 PROVED THAT MOVE FORWARD COLLABORATIVELY

28. THANK YOU!
