Sir - The editorial "Noise blight" (Flight International, 16-22 July) points out a flaw in the proponents of aircraft-noise reduction.
Frequently, our cause is diluted by these apparent inconsistencies and unrealistic demands which occur between the various interested parties. This same inconsistency is used against us at seminars and debates, by the aviation industry and by the media when discussing aircraft-noise issues, which in turn weakens our case.
While we advocate any reduction in the noise climate from whatever method, the Federation realises that there are many commercial pressures and trade-offs, which have to be taken into account. There is a strong need, however, for common cohesive agreements to noise regulations across national and international borders (not just those of Europe). Then we might be able to work together and move forward in conjunction with the airline industry.
Lastly, as in many other areas of European legislation, there is a need for an injection of large doses of common sense. If a Chapter 2 aircraft becomes a Chapter 3 one by a combination of hushkitting and new operating procedures, then a Chapter 3 aircraft it becomes.
