The IOA have responded to questions relating to noise in the Civil Aviation Authority consultation on the Future of UK Aviation. In addition to reporting the number of people exposed to aviation noise in the UK, the IOA would like to see metrics reported to cover both the national noise impact, which will be of interest to track progress to achieve DfT aviation noise policy aims and to assist stakeholders affected by noise from individual airports in understanding their noise, how it has changed and how it is being managed.
