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