I have been the go-between in a previous life re noise, operators, communities etc. In the UK rule 5 applies, also importantly, there is no statutory definition of 'on or off-track', so a prosecution for poor track keeping is to date, impossible. The best way to progress these issues is by having local procedures to adhere to and ensuring all pilots are properly briefed and aware of the issue. The primary issue should always be safety, tie that to rule 5 and you won,t go far wrong. If you are in the London area or anywhere on the A1 corridor my assistance can be bought for BEER!. There is a precedent in the courts at Heathrow but can't recall details, where the issue of tresspass (overflying a property) was addressed, and the plaintiffs lost.
