Airports - and the noise problem
• Opposition to aviation has grown over the last 20 - 30 years
• - and has gained substantial political momentum
• Aircraft noise is still the single most important cause of community opposition
• Politicians have reacted fiercely against aviation noise – laws, regulations, barriers against infrastructure development

Growth - a problem?
• With a traffic growth of 4% p.a. or 5% p.a. the total traffic volume will increase (2001 = 100)

Increase in noise exposure
• An annual growth will lead to an increase in noise exposure

Policy- what airports want
• Airports aim to growth of aviation
with minimum restrictions
and maximum flexbility
![Page 8: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/8.jpg)
Airports’ Noise PolicyWhat to achieve
• Meeting public demand for aviation
• Continued development of aviation
• Economic development
• Traffic development
![Page 9: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/9.jpg)
Airports’ Noise PolicyWhat to avoid
• Further political interference in environmental requirements to aviation
• Proliferation of different noise standards and requirements in different regions and countries
![Page 10: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/10.jpg)
ACI Policy at CAEP5
• Cumulative increase in stringency of 14 dB with at least minus 4 dB at each measurement point for future aircraft
• Traffic growth of 4 or 5 percent per year will require 1 dB increase in stringency every 5 years if noise exposure is not to increase
• Phase out in 5 years for all aircraft not meeting Chapter 3 Standards with 5 dB margin
![Page 11: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/11.jpg)
Outcome of CAEP5Noise
• Cumulative increase in stringency of 10 dB and the sum of any two points must be at least 2 dB
• Unspecified commitment for future revision of standards
• No phase out
![Page 12: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/12.jpg)

• Environmental problems often occur at the world’s busiest airports
• Many of these have found their own environmental solutions
• Top 20 airports accounts for 28 % of world traffic
![Page 13: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/13.jpg)
Dialectic
• Noise problems are local problems that can best be solved on an
international basis
• This calls for international cooperation between responsible aviation partners
![Page 14: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/14.jpg)
Responsibility
• In a world with increasing public demand and• No international commitment on relief
Airport management must
• Be responsible• Act with conscience
![Page 15: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/15.jpg)
ICAO Balanced Program
• What to consider
– Stringency– Land Use Planning– Operational Measures
• Procedures• Restrictions
![Page 16: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/16.jpg)

Stringency
• Worldwide standards– Governed by ICAO Set at Assembly or Council decision and often a delicate compromise
• Such standards may not be sufficient in some regions, in some nations or at some airports
![Page 18: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/18.jpg)

Land Use Planning Why?
• Control the use of land in relation to– Noise Exposure
• 24 h basis• Short term - ½ h or 1 h basis
– Maximum Noise Level
• Should protect against annoyance or sleep disturbance
- and neighbors too close to airport
![Page 20: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/20.jpg)
Land Use PlanningHow?
• Administrative levels– General Directive on Land Use– Control of local planning - different needs– Control of building permissions (prohibition or
additional noise insulation requirement)
• Noise insulation programs and shielding• Buy out• Relocation of inhabitants and/or houses
![Page 21: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/21.jpg)

Operational Procedures
• Preferential Runway System - Wind - Noise - Aircraft type
• Noise Abatement Procedures– Eventual dedicated for special purpose
• Noise Preferential Routing
• Adjustment of flight paths
• Flight Path Adherence
![Page 23: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/23.jpg)
Operational Restrictions
• Aircraft type – could be combined with stage length
• Time of day– Noise Exposure and/or Maximum Noise
Level
• Aircraft classification

Classification System
• Manufacturers’ Design Target
• Operators’ Guideline for Equipment
• Airports’ Guideline for Classification
• Universal Operational Opportunities
• Efficient Aviation Industry
• Proof of Responsibility

Balanced Programme - and the future
• Many Airports will have no relief from insufficient results of CAEP5
• At Many Airports Land Use Planning has been effective for years
• Many Airports have introduced all operational procedures
- and will therefore have no other option than operational restrictions
![Page 27: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/27.jpg)
Future Challenges for airports
• Increase in traffic, but no increase in noise
• Airports can not afford to loose credibility
• Public Relation
![Page 28: Noise Problems and the Balanced Program](https://reader036.vdocuments.us/reader036/viewer/2022070400/5681352f550346895d9c96dc/html5/thumbnails/28.jpg)
One way ?
• Your noise complaint has made a deep impression on our airport management
• We have never experienced problems of a similar serious nature
• You may retain this letter as evidence of our most sincere sympathy
