Mr Jacobi asked the Minister for Transport, upon notice, on 2 April 1980:

(   1 ) What is the effective perceived noise level of Boeing 767 and 737 aircraft, to be purchased by Ansett Airlines of Australia, compared with aircraft currently in use in Australia.

(2)   Will changes need to be made to (a) the runway and taxiways and (b) terminal facilities at Adelaide Airport,

South Australia should these aircraft be introduced on regular flights to Adelaide: if so, what changes will be required.

(3)   Has his attention been drawn to a report in the Australian Financial Review of 28 February 1980 which stated that Trans Australia Airlines had no immediate plans to use Airbus aircraft for flights to and from Adelaide, following their introduction in 1981.

(4)   Is the Airbus quieter than existing aircraft; if so, and as the Adelaide Airport is located in a built-up area, why will there be a delay in the introduction of these quieter aircraft to Adelaide. .

(5   ) Will the new Boeing aircraft to be purchased by Ansett be introduced on the Adelaide services; if so, when.


Mr Hunt -The answer to the honourable member's question is as follows:

(1)   The Effective Perceived Noise Level (EPNL) of the B737-200 aircraft compared with the domestic airline aircraft currently in use in Australia is shown, for the three standard international noise measurement positions, in the table below. The noise levels of the Boeing 767 are not yet known as the aircraft prototype has not flown and therefore no measurements have been taken. However, in its type certification process the Boeing 767 will be required to meet the latest noise standards established by the International Civil Aviation Organisation (ICAO) and these are quieter than the standards applicable to the older comparable aircraft.

(2)   Introduction of Boeing 737 aircraft will not necessitate changes to facilities at Adelaide Airport as these aircraft are less demanding on pavements and terminal building capacity than other jet aircraft already operating to Adelaide.

Larger wide-bodied aircraft such as the Boeing 767 and Airbus A300 will require minor changes such as widening fillets at some intersections of runways and taxiways because of the wider track of these aircraft.

Difficulties are already being experienced at the existing terminal building as a result of overcrowding during peak periods. These problems will become more acute following introduction of wide-bodied aircraft. Proposals are presently being formulated as to the most effective ways of overcoming these deficiencies.

(3)   Yes.

(4)   The Airbus is quieter than all other comparable types of airline jet aircraft currently flying in Australia. The deployment and introduction into service of the Airbus aircraft at any airport is a commercial decision by TAA subject to the operational requirements of the Department of Transport.

(5)   The proposed acquisition of Boeing aircraft by Ansett is currently being assessed by the Depanment of Transport. Ansett have not yet provided information regarding deployment of the new Boeing aircraft.
