ATAC – Who We Are

How It All Started ?

Commercial Aviation In The 60’s & 70’s

What Has Changed ?

Where To From Here ?

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

Always In Spotlight

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

What Causes Noise

Engines » Low Bypass Turbofans» Turbo Jets» Propeller Driven

Airframe Design Climb Out Landing Reverse Thrust Taxiing Engine Testing

What Has Changed

Engine Types – High Bypass Turbofans New Composite Materials

» Lighter» Quieter

Twin Engine AircraftNew Aerodynamic Shapes RNAV Sid DeparturesNoise Abatement Procedures

» No Reverse on Landing» NADP Departures

NEF RecommendationsLand Scarcity

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.

Noise Abatement Woes

40 Years Old

Do Not Reflect Today’s Technologic

Reality

Costly

Cause Noise Pollution

Burn up Precious Resources

Where to From Here

NEF Contour Enforcement

Government Role

The IssueJet 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.
