The pay-off, in the final analysis needs to be a better air transport system for the traveller. This will, in turn, generate more traffic for the airline and hence more business for the aircraft manufacturer. To achieve a substantial and profitable share of the available market for new aircraft the manufacturer's product must be produced at the right time, meet the requirements of the airlines, and be competitive in terms of price and capability with the products, both new and existing, of his competitors. Advanced technology, applied in a cost effective manner, can be one of the ways of achieving this competitiveness and of improving the air transport system.
