HC Deb 27 August 1968 vol 769 cc291-2W
Mr. Onslow

asked the President of the Board of Trade what proposals he has to introduce noise limits for light aircraft and helicopters.

Mrs. Gwyneth Dunwoody

The initial noise certification plan excludes both helicopters and aircraft less than 12,500 lb. maximum take-off weight. Each category presents special problems of noise reduction and, pending further study, we do not think it expedient to defer the substantial benefits which the initial plan is intended to secure.
