Why haven’t you analysed the effect on Leq noise contours or SEL noise footprints?
The majority of this consultation relates to route positioning above 4,000ft; these changes are beyond the point where changes to route alignment are expected to have a significant effect on noise contours/footprints.
Part B relates to changes in the vicinity of Gatwick airport below 4,000ft. Assessment of noise contours/footprints requires assessment of specific routes; these will be determined in the on-going design process that will consider the feedback from this consultation.
During this design work we will undertake assessments required by the CAA and should there be any changes to noise contours and footprints we will undertake further consultation with any areas adversely affected.
