HC Deb 23 July 1986 vol 102 c223W
Mr. Carter-Jones

asked the Secretary of State for Trade and Industry what information he has regarding new aircraft and engine developments under consideration by various manufacturers which are expected to generate noise levels which meet the requirements of the International Civil Aviation Organisation, chapter 3, but do not match the noise levels of the majority of aircraft and engine types currently in production; and if he will make a statement.

Mr. Pattie

Annex 16 to the Convention on International Civil Aviation (ICAO Annex 16) applies to complete aircraft and not to engines in isolation. The majority of the subsonic jet types now in production comply with the standards of chapter 3 of annex 16. Any subsonic civil jet aeroplane or large propeller-driven aeroplane currently under development will have to meet these same standards. Until these have flown it is not possible to compare their noise levels with those of other aircraft.
