**Notes:**
Good morning everyone and welcome.

We have invited all of you here today, representing all critical disciplines of the industry,  to begin implementing additional improvements in our nighttime flight tracks through the use of technology.

These types of cooperative initiatives are ESSENTIAL to ensure that airports can meet demand while balancing community concerns.

Today, we are launching our latest initiative called “Advanced Flight Track Procedures”.

I am very pleased to see all of you here to participate in our comprehensive program with the mutual goals to improve efficiency, enhance safety, and yes, reduce noise impacts.

## Slide 3

**Notes:**
First, some background information:
This past February, Mayor Daley announced the WORLD GATEWAY PROGRAM.
The Program will include roadway improvements, the design and construction of new Terminals 4 and 6, the reconstruction of Terminal 2, the construction and operation of new FIS Facilities, and the reconfiguration of space in the existing domestic and international terminals to allow code sharing airline partners to occupy contiguous gates, thereby facilitating the efficient connection of international and domestic passengers.  

## 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

**Notes:**
The World Gateway Program will allow the Airport to efficiently meet anticipated growth in international passenger demand through the foreseeable 15-year planning period. These improvements will preserve competition and enhance system performance, as well as promote the continued economic health of the northern Illinois/Chicago metropolitan region.  In addition, these improvements are intended to be responsive to the passenger needs of O’Hare’s hub and spoke-market airlines, while maintaining existing programs and future efforts to further reduce aircraft noise the surrounding communities.

## 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

**Notes:**
The High Density Rule was originated in 1969 by the 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.

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

**Notes:**
In 1996, Mayor Daley formed the O’Hare Noise Compatibility Commission 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.

The Commission is comprised of 17 Municipalities and 8 School Districts.

## STANDING COMMITTEES

**Notes:**
The Commission has three standing committees:

the Residential Sound Insulation Committee, 
the School Sound Insulation Committee, and
the Technical Committee

## FLY QUIET PROGRAM

**Notes:**
In June of 1997, Mayor Daley announced our FLY QUIET PROGRAM.

The FLY QUIET Aviator’s Manuals were designed as an educational tool to promote the City’s noise abatement procedures and the content of the FAA’s O’Hare Tower Order.  The manuals include:

Land Use around O’Hare,
an Airport Layout Diagram,
our Arrival & Departure Procedures, 

[continued on next slide........]

## FLY QUIET PROGRAM

**Notes:**
Preferential Runway Use, and
Ground Run-Up Procedures.

## AIRPORT NOISE MONITORING SYSTEM

-  Collects Flight Tracks and Noise Data                       	by Aircraft within 40 nautical miles
- Nighttime Flight Track Deviation Reports
- Public Information
- Ability to Show Improvements

**Notes:**
In 1996, the City completed the installation of our $4 million Airport Noise Monitoring System.

Our system collects flight tracks and noise information 24-hours a day, 365 days a year for all flights within 40 nautical miles using the FAA’s radar data.  The System also includes 28 noise monitors around O’Hare and 12 near Midway Airport.

We use the data to track trends in adherence to our Fly Quiet procedures, which starting this August will include nighttime preferential flight track deviations by airline.   Mayor Daley committed to publicly sharing this information with the Technical Committee of the O’Hare Noise Compatibility Commission on a quarterly basis.

The Advanced Flight Track Procedures initiative will allow us to use both existing Area Navigation technology and more advanced navigation technology, such as FMS to show continued improvements and reduce noise in the communities surrounding O’Hare.

## NOISE MONITORS

**Notes:**
This map shows the location of the 28 existing and 10 proposed noise monitor locations around O’Hare.

## EXAMPLE REPORTS

**Notes:**
These example monthly reports show the locations of noise complaints and runway use.

## EXAMPLE REPORTS

**Notes:**
The System is also used to show aircraft flight tracks by airline.

## 1997/2000 NOISE CONTOUR

**Notes:**
In December of last year, we released our latest noise contour at our O’Hare Noise Compatibility Commission meeting.

This map shows an overlay of the actual 1997 noise contour compared to the predicted year 2000 noise contour.

As you can see, we are expecting a reduction in noise due to the change to an all Stage 3 fleet.  Actually, we are predicting nearly a 50% reduction in the number of homes impacted by significant noise levels.  

The City and the airlines committed to sound insulating all of the single-family, owner-occupied homes that remain within the 70 DNL & Greater of the actual year 2000 contour when it is developed.

Collectively, we have the opportunity to minimize this contour even further and reduce the number of homes to be insulated.

## 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

**Notes:**
In conjunction with the release of the noise contour, the specific commitments made by the City and the airlines were to:

Extend the Sound Insulation Program Beyond 1999
Seek Nighttime Fleet Mix Improvements
Appoint Designated Fly Quiet Directors, many of whom I am pleased to 	see here today
Develop Performance Measures, such as our quarterly Fly Quiet 		Adherence Summary
Expand Educational Programs for Tower staff and airline flight crews, 	and
Pursue Fly Quiet Program Enhancements

With the Advanced Flight Track Procedures initiative, all of these commitments will have been met.

## 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

Implement GPS technology to better utilize compatible flight 	tracks during the nighttime hours

Implement air traffic control simulator testing and training

Monitor shoulder hour runway use and flight track program

## 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.

**Notes:**
The Chicago Airport System recognizes that GPS can assist us in our goals.  In 1998, the City joined the FAA, United Airlines, and Honeywell to form an Industry-Wide Partnership to implement the Local Area Augmentation System here in Chicago.

The City has committed over $3 million to purchase Differential GPS equipment that will be operational for our airports in the year 2001.  We are currently in the process of selecting sites for the LAAS ground base units.

The Advanced Flight Track Procedures will set the stage for eventual GPS procedures to further refine our flight tracks.

## TRACK MAPS

_**Legend**_

- Preferential Flight Track

- Shoulder1 Hour Departures

- 11 p.m. to 6 a.m. Departures

- 1 10-11pm and 6-7am

- NOTE:  Flights shown until 3,000 ft. MSL

**Notes:**
From our Airport Noise Monitoring System, we have prepared a few slides to demonstrate the challenge we hope to tackle with our Advanced Flight Track Procedures.

This exhibit shows O’Hare in the center with our preferential nighttime flight tracks as the black lines.  The actual nighttime flight tracks below 3,000 feet are shown in blue and red.  The tracks in red occurred between 11 p.m. and 6 a.m.  The tracks in blue occurred during the shoulder hours of 10-11 p.m. and 6-7 a.m.  

The goal of these procedures is to promote the use of flight tracks over noise compatible areas without increasing controller workload or aircraft delays, while providing predictable, repeatable execution of flight tracks by pilots and aircraft.

## TRACK

- REPORTS

**Notes:**
Our Airport Noise Monitoring System can quantify this information by airline.  This chart gives an example of information that has been developed for use by the Technical Committee of the O’Hare Noise Compatibility Commission to monitor trends.

Already, because of the FLY QUIET Program, we see that the work of the carriers and the FAA has controlled flight track dispersion rates, but all of us in this room know that we can do better with the use of technology.

## STATISTICS

**Notes:**
These distribution curves provide statistical information about the adherence to our nighttime preferential flight tracks.

For example, the top chart shows that 71.6% of the departures in March of 1999 during the shoulder hours of 10-11pm and 6-7am were within 1nm of the theoretical flight track.  The bottom chart shows that 87.4% of departures were within 1nm between 11pm-6am.

Other airports have established corridors of similar widths, such as London Heathrow, Phoenix, Seattle, and John Wayne Airport.

With the implementation of Advanced Flight Track Procedures for every runway at O’Hare, we can show improvements to flight track adherence over time.

## SUMMARY

- Aggressive Program Using Existing Technology to Improve Nighttime Flight Tracks
- Goal is to have usable procedures within a year.
- Work towards RNP of GPS procedures in the future.

**Notes:**
We are excited about our innovative program.  We plan to work closely with this group to implement procedures for use during the most sensitive nighttime hours for all runways by this time next year.

Once accomplished, we hope to have all of you assist us in the future in designing Required Navigation Performance, RNP, of GPS procedures for arrivals and departures.

Thanks again for your level of commitment as O’Hare International embarks on this ground-breaking initiative.  We know we have many challenges ahead, but we feel with the talents of everyone collected here today, we will achieve our mutual goals to provide safe, efficient operations with reduced nighttime noise impacts.
