Balanced Approach to Aircraft Noise Management - In 2001, the ICAO Assembly endorsed the concept of a "balanced approach" to aircraft noise management. The Assembly in 2007, reaffirmed the "balanced approach" principle and called upon States to recognize ICAO’s role in dealing with the problems of aircraft noise . This consists of identifying the noise problem at an airport and then analysing the various measures available to reduce noise through the exploration of four principal elements, namely reduction at source (quieter aircraft), land-use planning and management, noise abatement operational procedures and operating restrictions, with the goal of addressing the noise problem in the most cost-effective manner. ICAO has developed policies on each of these elements, as well as on noise charges. The recommended practices for balanced approach are contained in Doc 9829 - Guidance on the balanced approach to aircraft noise management.
