1. ICAO ENVIRONMENTAL COLLOQUIUM 9-11 April 2001 Montreal
Session 5: Aircraft Noise - The Way Forward
Dr Philippe Rochat
AIR TRANSPORT ACTION GROUP

2. SUSTAINABLE DEVELOPMENT
Calls upon civil aviation to meet the growing demand of travellers and shippers in a sustainable manner, balancing economic progress, social development and environmental responsibility
Calls upon our society to recognise the decisive role of aviation in a sustainable global economy

3. NOISE EQUATION
Permanent search for a balance between universal rules necessary to global aviation and airport-based local requirements
Balance in ICAO hands, based on CAEP achievements:
New chapter 4 certification standards
Re-certification process
Balanced approach with no global phaseout

4. ICAO GLOBAL FRAMEWORK FOR A BALANCED APPROACH
Airport by airport based approach
Aircraft restrictions only as a very last option
Preservation of aviation unique intercontinental network

5. AIRPORT-BASED APPROACH
Local issue: each airport is different
No regional “noise sensitivity”
Noise abatement to be tailored to local situations, but local measures to be harmonised internationally for preventing harmful unilateral measures

6. BALANCED APPROACH
Land-use control, mitigation measures, operational procedures & voluntary agreements
Land-use Management
to prevent incompatible residential developments
to avoid quieter aircraft benefits to be lost by encroachment of new residential areas closer to airport
to better share with neighbouring communities the economic & social benefits of air transport

7. AIRCRAFT RESTRICTIONS AS A VERY LAST OPTION
Only where and when the other measures have been fully exploited without solving completely the problem
Only at critical moments (to start with)
Only after consultation with airlines
Only if ICAO defines the (chapter 3) aircraft to be locally restricted

8. AIRCRAFT RESTRICTIONS CONTEXT & EXEMPTIONS
On one side: the ICAO “Chapter 2” Resolution
On the other: Growing phaseout pressures
ICAO to guide and control, while helping airports to resist
ICAO to also grant exemptions for preserving aviation unique intercontinental network (and thus satisfy operators from develping countries)

9. ATAG RESOLUTION ON SUSTAINABLE AVIATION
Submitted today to ICAO
to stimulate noise debate
to broaden environmental issues
to work all together
to be proactive
to consolidate aviation contribution to a sustainable global economy
