• Our noise envelopes review, published as CAP1129, is designed to inform the definition of a noise envelope concept which can be applied to airports looking to increase their capacity. Possible envelope parameters are presented, and consideration is given to setting parameter limits in the context of sharing the benefits of quieter aircraft technology and providing assurance to stakeholders. The process of implementing a noise envelope is looked at, as are operational aspects such as how compliance with the limits is monitored and enforced.
