Aircraft Noise

Responsibly Addressing Aircraft Noise

Technological advancements, operational measures, infrastructure and air traffic management enhancements can all contribute to mitigate aircraft noise. Thanks to the efforts of the air transport industry, at many airports the noise climate has improved significantly over the last decades.

In 2001, the ICAO Assembly unanimously endorsed the ICAO Balanced Approach by adopting Resolution A33-7. The Balanced Approach provides a transparent process for managing demonstrated noise problems on an airport-by-airport basis. It consists in the evaluation of all available options with the goal to identify the most suitable measure or combination of measures to achieve the noise abatement objective with minimal negative impacts on the economy. The Balanced Approach identifies four elements to address noise at airports: reduction at source, land-use management and planning, noise abatement operational procedures, and operating restrictions.
