Aircraft noise
Reducing aircraft noise is a major component of environmental policy on air transport. Over the last 30 years, aircraft noise has been cut by as much as 75% as a result of a combination of technological innovations and international policies on aircraft noise (EC, 2013c). Europe’s vision for aviation is a further 65% reduction by 2050 in perceived noise emission from flying aircraft relative to new aircraft in 2000 (EC, 2011a). This target is to be achieved through a combination of measures including more stringent noise standards for new aircraft, sustainable management of areas around airports, operational procedures to reduce noise impact on the ground, and allowing operating restrictions (EC, 2013c).
