INTRODUCTION

Industry-Wide Participation

Room to Improve Nighttime Flight Tracks

Comprehensive Approach

GOALS– Improve Efficiency

– Enhance Safety

– Reduce Noise Impacts

WORLD GATEWAY PROGRAM

Allows O’Hare to remain cost competitive among the North American International Gateways

Maximizes international air service opportunities Provides efficiencies for code sharing airline

partners Responsive to passenger needs Maintains existing and future efforts for noise

reduction

HIGH DENSITY RULE

Originated in 1969 Introduced by FAA as a temporary measure to

reduce delays Today’s technology and procedures have rendered

the rule obsolete O’Hare is the only hub-airport operating under the

restrictions of the High Density Rule Results in flights being forced into the early

morning and late evening hours when rule is not in effect

O’HARE NOISE COMPATIBILITY COMMISSION

Mission: To assist in developing meaningful methods of reducing the impacts of aircraft noise on our surrounding neighborhoods through home and school sound insulation, and to reduce, wherever possible, aircraft noise at its source.

Comprised of 17 Municipalities and 8 School Districts

AIRPORT AND AIRLINE COMMITMENT FOR NOISE COMPATIBILITY

Extend the Sound Insulation Program Beyond 1999

Seek Nighttime Fleet Mix Improvements

Appoint Designated Fly Quiet Directors

Develop Performance Measures

Expand Education Program

Pursue Fly Quiet Program Enhancements

Fly Quiet Program enhancements may include:– Equip aircraft with Area Navigation

technology, such as FMS for improved pilot execution of flight tracks

– Implement Global Positioning Satellite technology to better utilize compatible flight tracks during the nighttime hours

– Implement air traffic control simulator testing/training

– Monitor shoulder hour runway use/flight track program

AIRPORT AND AIRLINE COMMITMENT FOR NOISE COMPATIBILITY

GPS TECHNOLOGY

Government-Industry Partnership formed in 1998 to pursue LAAS GPS

City has committed over $3 million towards differential GPS capability for the Chicago Airport System due in 2001.
