§ Mr. Jesselasked the Secretary of State for Trade if he intends to restore the Heathrow sound insulation grant scheme, and to extend its boundaries to include additional areas severely affected by aircraft noise such as Whitton, Twickenham, Teddington and the Hamptons.
§ Mr. Clinton DavisWhen I have received the British Airports Authority's proposals I shall consider them, together with the many other representations that I am receiving on the subject, and decide what further noise insulation measures may be necessary.
§ Mr. Jesselasked the Secretary of State for Trade when, and why, the scheme for sound insulation grants near Heathrow Airport ceased; whether he is satisfied with the noise and number index as a 400W measure of aircraft noise nuisance in general and as a basis for determining insulation schemes against aircraft noise in particular; whether he intends to replace or consider replacing the noise and number index as a measure of aircraft noise nuisance; and if he will make a statement.
§ Mr. Clinton DavisThe noise insulation grants scheme for Heathrow closed to applications on 31st December 1977, as provided in Statutory Instrument 1975 No. 917. The noise and number index remains as good a general measure of aircraft disturbance as is available, but consideration of possible new statutory noise insulation measures will include the question of the appropriate measure of disturbance for this particular purpose.
