Senator KEEFFE asked the Minister for Civil Aviation, upon notice:

Can the Minister inform the Parliament of the measured amount of fall-out which could enter the atmosphere following flights by (a) Concorde supersonic jet airliners, and (b) various types of pure jet passenger aircraft now being used by Australian airlines.

Senator COTTON (New South WalesMinister for Civil Aviation) The answer to the honourable senator's question is as follows:

(a)   I have no detailed information on the amount of fall-out pollution which will occur from the Olympus engine installed in the Concorde supersonic transport. However, the production engine is expected to be relatively smoke-free and it is anticipated that the exhaust emissions will be comparable to those of the Pratt and Whitney JT9D engine with the new combustion chamber as installed in the Boeing 747B aircraft.

(b)   There is no really authentic measured figure for the exhaust emissions of current pure jet transport aircraft used by the Australian airlines. However, the exhausts of the various engines are estimated to contain pollutant, when measured as a percentage of the total air passing through the engine somewhere in the range of 0.002 per cent to 0.05 per cent.

In the total scene, experimental and observational work in the United States, particularly at Washington D.C., Los Angeles and New York, has shown that aircraft of all kinds are only responsible for between 1 and 2 per cent of the total emission of air contaminants produced in and around a typical metropolitan area. There is no reason to question the applicability of this information to the larger industrialised cities in Australia.
