This paper was requested to deal with (1) the future relations between designers and production; (2) the special problems to be faced by the production people and the assistance to be expected from the designers; and (3) how such design problems as pressurisation, silencing and the fitment of turbine engines were being tackled.

These terms of reference are very broad and probably can only be touched upon in a general way. I, personally, have been engaged entirely on the design side for the past thirty years and therefore it might have been more fitting if a member of the production organisation had been asked to give this paper.
