HC Deb 10 November 1980 vol 992 cc24-5W
Mr. Greenway

asked the Secretary of State for Trade if he will introduce new noise control regulations to restrict the maximum noise level of aircraft using Heathrow to 85 PNdB; and if he will make a statement.

Mr. Tebbit

No. As even the quietest modern jet aircraft would be unable to meet the limit of 85 PNdB at the present fixed noise monitoring points at Heathrow the imposition of such a restriction would effectively close the airport to commercial operations.
