How do you legislate to ensure that charter flights do not use an airport? Surely pricing them out of the airport is the best solution but can this really be set down in law?
While I see your point that BHD affects many more people, the number of people it affects to an intrusive extent is very small indeed. While for a few people having a barbeque in their back garden on a sunny saturday might be a bit pissed off, these flights pass close to where I live (albeit at a higher altitude) and cause virtually no problems, disruption or irritation.
And while roads may have lay in the same place for 100 years, the vivo truck clattering up the streets around when I live hasn't been. Change can be a pain in the hole but it's necessary and we might just have to limit our NIMBY mentality to take account of this.
