HC Deb 26 July 1977 vol 936 c156W
48. Sir Anthony Royle

asked the Secretary of State for Trade if he will make a statement about the noise effect of the standardised revised take-off procedures for all Trident aircraft.

Mr. Clinton Davis

I am advised by British Airways that the minor revisions to the take-off procedure introduced on 20th July will make no perceptible difference to the noise heard on the ground.
