HC Deb 06 April 1970 vol 799 c13W
Mr. Onslow

asked the Minister of Technology when he expects to be in a position to assess the noise characteristics of the production model of Concorde.

Mr. Carmichael

The assessment of engine noise on Concorde is a continuous process: estimates will be brought up to date as new flying evidence is accumulated. Our design aim remains that Concorde's noise should be no greater than that of existing subsonic jets.
