§ Mr. John Mooreasked the Secretary of State for Trade, to the extent that concession grants to offset noise disturbance were provided in the Heathrow area, based on the existing noise limits, and as he has exempted Concorde from these noise limits, if he will consider allowing 157W compensation based upon a more extensive noise print limit in the area and noise beyond the previous limits.
§ Mr. Clinton DavisThe noise insulation grants scheme at Heathrow is based on total noise disturbance as measured by the Noise and Number Index (NNI) contours. At least initially there will be so few Concorde movements at Heath-row that they are unlikely to make any significant difference to the NNI contours. I am not, therefore, considering any further revision of the grants scheme, but I shall continue to watch the position.
