HC Deb 21 March 1977 vol 928 cc378-9W
28. Sir G. Sinclair

asked the Secretary of State for Trade what is his latest estimate of the number of people affected by noise at Gatwick as measured by the population living within the 35 noise number index contour at the following dates: 1970, and 1975; and what is his estimate for 1980.

Mr. Clinton Davis

NNI contour calculations were not prepared for 1970, but, using 1972 instead, the comparative figures are as follows:

1972 30
1975 34
1980 61
The 1980 estimate assumes a passenger throughput of 10 million and 106,000 aircraft movements.

29. Mr. Jessel

asked the Secretary of State for Trade how many representations he has received in the last 12 months concerning the rate of climb of aircraft taking off from Heathrow.

Mr. Clinton Davis

Precise figures on the number of representations which have included the point are not readily available.
