CAA want your views on minimum requirements for noise modelling
The CAA are seeking to specify the minimum acceptable level of sophistication of noise modelling so to provide consistency across different groups of airports.
In order to carry out certain aspects of its regulatory duties, the CAA requires stakeholders (usually from airports) to provide them with outputs from noise modelling. Such outputs are typically in the form of sets of ‘noise contours’, along with the area they cover and/or the number of residents living within them.
Currently, different stakeholders use different levels of sophistication in this modelling, which is as expected since they have different numbers of residents affected by aviation noise, and may respond to the CAA in regard to different of thir duties. Up until now, it has been the responsibility of each stakeholder to decide on the level of sophistication of noise modelling appropriate for its circumstances.
