§ Mr. Hayhoe
asked the Secretary of State for Trade and Industry what were the total numbers and monthly totals of all aircraft landings and departures and of jet aircraft landings and departures at Heathrow between 23.30 and 06.00 hours and between 22.00 and 07.00 hours local time from 1st April to 31st October in 1971, 1972 and 1973.
§ Mr. Michael Heseltine
The details of jet landings and departures between 23.30 and 06.00 hours local time are as follows. The other information requested by my hon. Friend is not readily available but I will write to him as soon as possible.
further reduction of about 10 per cent. In addition to this further reduction in the numbers of movements, I am also extending the hours during which the restrictions on departures apply by half an hour on weekdays to 06.30 local time, and by two hours on Sunday to 08.00 hours. The extended period on Sundays will apply to all jet aircraft but on weekdays noise certificated aircraft will be exempt from the effect of the extension. I shall 15W shortly be considering the possibility of restrictions in winter months of 1974–75.
