ACI: Cautious over proposed new aircraft noise standards

The Committee on Aviation Environmental Protection (CAEP) of the International Civil Aviation Organization (ICAO) meeting in Montreal recommended new, stricter noise certification standards.



Among these recommendations was a proposed increase in stringency of 10 EPNdB over current Chapter 3 levels to become effective on 1 January 2006. However, these standards apply only to certification of new aircraft after that date and are not for operational restriction or phase out.



ACI`s position presented at CAEP called for adoption of an increased stringency of 14 EPNdN together with minimum reduction of 4 dB at each of the take-off, sideline and approach noise measurement points.



The airport community recognizes the step taken by CAEP in agreeing on a new noise standard to replace the current Chapter 3 standards which are almost 30 years old, but believes the proposed 2006 date comes too late to help the many airports now in desperate need of additional capacity to meet current and future traffic growth.



ACI also regrets CAEP`s inability to agree on operational restrictions and phase out of the many noisy aircraft which produce disproportionate noise and contribute heavily to overall noise levels around airports. ACI requested the phase out of such aircraft meeting current limits by a margin of less than 5 dB by 2005.



CAEP consists of experts from 18 ICAO Contracting States together with observers representing airports, airlines, manufacturers and various environmental organizations. Almost 200 participants attended this fifth meeting of CAEP. Their recommendations will be submitted to the Council of ICAO for review and further action.



ACI was represented at CAEP by Erik Nielsen (Copenhagen Airports) who chairs ACI`s Environment Standing Committee. He was accompanied by Committee members Lars Ehnbom (CAA Sweden), Makoto Hagiwara (Narita Airport Authority), Suzanne McLean (Tucson), Anne Murray (Vancouver), Volker Nitsche (Dusseldorf), Burr Stewart (Seattle). ACI was also represented by Director General Jonathan Howe, Environment Director Avi Gil, ACI ICAO Liaison Director Rod Heitmeyer and Richard Marchi from ACI`s North American office in Washington D.C
