§ Mr. Matherasked the Secretary of State for Trade and Industry what plans 111W he has for reducing night jet movements at Heathrow during the summer period.
§ Mr. OnslowThe ban on night jet departures between 2330 and 0600 hours, local time, is to apply from 1st April to 31st October, with exemptions only in exceptional circumstances, on the same lines as in 1972. But the time after which jet arrivals may not be scheduled to depart is being changed from 2315 to 2300 hours with effect from 1st June. Following consultation with airlines, and with the experience gained in operating the ban last year, the aim is to reduce total night jet movements—landings and departures combined—by about 10 per cent. as compared with 1972. Additionally, it is the intention to explore with airlines, and with the British Airports Authority, the possibility of extending in 1974 the night hours during which the restriction on departures applies, and of reducing the number of night movements by jet freight aircraft.
