HC Deb 18 December 1958 vol 597 c222W
79. Mr. Mikardo

asked the Minister of Transport and Civil Aviation whether he will now arrange for the reconsideration, and possible re-establishment, of performance schedules for the Viking aircraft.

Mr. Neave

New safety performance regulations will come into force on 31st March, 1960. Before that date a revised and expanded performance schedule will be issued.

86. Mr. Gresham Cooke

asked the Minister of Transport and Civil Aviation if, before he gave permission for the Boeing 707 aircraft to land at London Airport, he satisfied himself it was fitted with a silencer; and to what extent his approval was made conditional on an improvement in the silencing method.

Mr. Neave

Before allowing the Boeing 707 to use London Airport we were satisfied not only that a silencer was fitted but that the operating techniques to which we gave approval would reduce, as far as was practicable, any disturbance which this aircraft might cause.
