Each year Queenstown Airport prepares Annual Aircraft Noise Contours (AANC), which show where noise from aircraft flying overhead averages, over a year, 60 dBA and 65 dBA. Over time, the contours give the public an indication of how aircraft noise at any time compares to the final 2037 noise boundary allowed for in Plan Change 35. The contours also give homeowners in the noise areas an indication of when they are likely to receive offers of acoustic treatment. More properties will become eligible for noise reduction funding as aircraft movements gradually increase.
