§ Mr. Greenwayasked the Secretary of State for Trade if he will introduce new noise control regulations to restrict the 25W maximum noise level of aircraft using Heathrow to 85 PNdB; and if he will make a statement.
§ Mr. TebbitNo. 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.
