1 ACI Noise Rating Index and its applications ACI Airport Environmental Colloquium Cairo, 27 November 28 Saburo Ogata Narita International Airport Corporation Background Noise from aircraft at various airports is a major environmental issue and has led to operational limitations and opposition to airport expansions or constructions ICAO has been addressing the issue of aircraft noise since 196s and has developed aircraft noise certification standard. The latest ICAO Chapter 4 noise standard neither reflects the noise performance of the best available in current production, nor provides a reference for future aircraft performance. ACI GB directed it s Environment Standing Committee in April 22 to draw up a tool for rating aircraft noise In October 22, the ACI Aircraft Noise Rating Index was adopted by ACI s GB

2 The objectives of Noise Rating Index Encourage global consistency in the implementation of effective airport noise management programs Enable airports to communicate effectively with communities and governments about noise issues Provide an effective tool that is compatible with the ICAO system of noise certification standards Provide a consistent reference point to encourage manufacturers to develop and market the possible quietest aircraft and encourage airline industry to upgrade their fleets as rapidly as possible Noise Measurement Points for ICAO Aircraft Noise Certification Sideline(lateral) 45m 65m flyover 2m approach

3 ACI Aircraft Noise Rating Index The Index places aircraft into six categories of noise performance, ranging from A to F The index applies to aircraft with noise certification data stated Aircraft must be required to meet both criteria, upper and lower Criteria to be met concurrently Cumulative EPNdB reduction from ICAO Chapt er3 st andard of at least : Individual EPNdB reduction from ICAO Chapt er3 st andard at each Noise measurement point of at least : Cat egories F E D C B A Less than Not applicable How to calculate the Index =22.9 (cumulative) Class A

7 Conclusion The ACI Environment Standing Committee drew up the Noise Rating Index linked to ICAO Noise Certification Standard In order to promote the use of low-noise aircraft, Narita Int l Airport introduced a new landing charges based on ACI Noise Rating Index from October 25 Though we cannot exactly determined the contribution of introducing new landing charges, ACI Noise Rating Index works well as an incentive to reduce noise at source As the lower Index Classes A through C can have lower fuel consumption and gas emission, the Index system leads to a reduction of environmental burden at the airport.
