In that case, in my view, there's a weakness or a hole in the law and the regulations where they're only required to consult if they wish to make a change to the existing rules and procedures, because if there are a significant number of complaints coming from residents who are directly affected by the flight paths and the hours of the flights, there should be a requirement for further consultation to determine whether or not those procedures and rules and regulations regarding noise abatement for that particular airport are still effective.
