§ Mr. MacdonaldTo ask the Secretary of State for Defence if he will list the aircraft types whose source noise and operational flight profiles are held in the data bank for(a) the Airnoise I aircraft noise model and (b) the Airnoise II aircraft noise model.
§ Mr. FreemanAll the aircraft types used for the Airnoise computer models are listed in a report called "External noise of MOD military aircraft", a copy of which is in the Library. At RAF Stornoway, the noise source data and operational flight profiles for the Phantom and Tornado aircraft have been used to produce the predicted noise contours.
