Senator CARRICK (NEW SOUTH WALES) - Has the Minister for Civil Aviation seen the published statement that in 1970 approximately 26,000 supersonic flights took place over the United States of America? How does the airfield noise level of the Concorde aircraft compare with that of current commercial aircraft such as the DC8 and Boeing 707? How will the smoke emission of the operational type Concorde in take-off and landing compare with that of current commercial aircraft?

Senator COTTON - The number of flights of supersonic aircraft over the United States referred to by the honourable senator is substantially correct. I asked for this information and was advised that in the last year about 26,000 supersonic flights were made over the United States. As to noise, the prototype Concorde is the aircraft likely to make a flight to Australia. On approach and take-off its noise level is very close indeed to that of the Boeing 707 and DC8 now in service. The sideline noise on take-off is slightly higher. The commercial version of the Concorde which will enter service in due course will be quieter in all respects than the Boeing 707 and DC8 now in service. As to smoke emission in the prototype model, some smoke will be seen but when the production model enters commercial service there will be no smoke.
