ICCAIA Welcomes ICAO Agreement on Airplane Noise Reduction

  • January 1, 2014

February 12, 2013 - The International Coordinating Council of Aerospace Industries Associations (ICCAIA) welcomes the new agreement on noise reduction reached by the International Civil Aviation Organization’s (ICAO’s) Committee on Aviation Environmental Protection (CAEP), during its ongoing meeting in Montréal, Canada. The agreement lowers the maximum allowable noise levels required by the ICAO noise certification Standard for civil airplanes. This is another major step in how civil aviation is addressing environmental concerns on a global basis.

The new ICAO agreement establishes a more stringent maximum allowable noise level that is 7 decibels (EPNdB or “effective perceived noise dB”) lower than ICAO’s current Chapter 4 noise Standard implemented seven years ago. Following the agreement by CAEP, the new noise Standard, Chapter 14, will be presented for review and final approval by the ICAO Council later in 2013. The noise reduction requirement will be applicable to larger aircraft in 2017; followed by smaller aircraft in 2020.

Industry members of ICCAIA – alongside ICAO member states, intergovernmental agencies, nongovernmental organizations and other concerned stakeholders – contributed extensively to the analysis in order to help inform ICAO-CAEP on the environmental, technological and economic impacts of new noise reduction levels. ICCAIA members are also working within CAEP to achieve a first-of-its-kind CO2 standard for aircraft as quickly as possible. Progress in developing a certification standard for CO2 emissions was made at the recent ICAO-CAEP meeting as well.

Investments by aerospace manufacturers continue to lead to significant advancements in aircraft, engine, and nacelle noise reduction systems and technologies. Today’s most efficient and environmentally progressive airplane has only a small fraction of the noise footprint of its equivalent 1970s predecessor. New airplanes designed to this latest ICAO standard will be instrumental in helping meet ICAO's goal of limiting or reducing the number of people exposed to aircraft noise around the globe.

Note to editors
ICCAIA is the international organization of aerospace industry manufacturing associations. ICCAIA was established in 1972 to provide the civil aircraft industry a means to be represented with observer status in the deliberations of the UN’s International Civil Aviation Organization (ICAO). ICCAIA was constituted by the Aerospace Industries Association of America (AIA) and the European Association of Aerospace & Defence Industries (ASD). Subsequent members of ICCAIA now include the Aerospace Industries Association of Canada (AIAC), the Society of Japanese Aerospace Companies (SJAC), the Aerospace Industries Association of Brazil (AIAB) and the Russian Union of Aviation Industrialists.
