§ Mr. Greenway
asked 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. 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.
