Recommended Method for Computing Noise Contours Around Airports
|Publication Date:||1 January 2018|
This manual on the Recommended Method for Computing Noise Contours Around Airports (Doc 9911) replaces similar material contained in the Recommended Method for Computing Noise Contours Around Airports (Circular 205), which was approved by the ICAO Committee on Aviation Environmental Protection (CAEP) at its first meeting in 1986.
This first edition of Doc 9911 contains material developed by CAEP with the assistance of aviation stakeholders, including regulatory authorities, air traffic management providers, airport operators, manufacturers, airline associations and airlines, as well as the ICAO Secretariat. It was approved by CAEP at its seventh meeting in February 2007.
This manual is intended to assist States in the computation of noise contours around airports, using the most up-to-date procedures and the most recent aircraft noise and performance information available. It describes the major aspects of the calculation of noise contours for air traffic at an airport, including three ways in which most practical noise models calculate aeroplane single event noise levels. This manual is an important advance on Circular 205 in that it is linked to an international aircraft noise and performance (ANP) database which is accessible online at http://www.aircraftn
