asked the Secretary of State for Trade what is the forecast of his Department of the annual percentage growth in air passenger travel, air cargo movements and aircraft movements for the period 1975 to 1985 for movements from the United Kingdom to (1) Europe, (2) Africa, including South Africa, and (3) South Africa, respectively.

The preparation of forecasts of this kind is a function primarily of the Civil Aviation Authority. I have asked the Chairman to write to the hon. Gentleman.
