BackThe four pillars of the ICAO Balanced Approach
A useful framework for understanding aircraft noise management can be found in the International Civil Aviation Organisation’s (ICAO) ‘Balanced Approach’. ICAO’s overarching policy on aircraft noise, especially comprehensive guidance on its reduction, is published in ICAO Doc. 9829 – Guidance on the Balanced Approach to Aircraft Noise Management, and consists of four key pillars:
Pillar 1 – Reduction at the source
Noise reduction at the source with quieter aircraft and noise-reducing engine/wing technologies and advancements in airframe design
Pillar 2 – Land use planning & management
Land use planning and development controls to safeguard and protect local communities from aircraft noise disturbance and passive noise control programs
Pillar 3 – Noise abatement operational procedures
Noise abatement operating procedures in the air and on the ground
Pillar 4 – Operating restrictions
Operational restrictions imposed on certain aircraft types and airport runway use and hours of operation
