ABSTRACT

The A330/A340 project is a twin programme — the first time that an aircraft has been designed from the outset both with four engines, and also with two engines. Both aircraft types have essentially the same passenger and freight capacity. The four-engined A340 is optimized for long-range missions, but is also efficient at shorter ranges. With two engines, the A330 offers even better operating economics for the missions where an airline does not need the very long range of the A340.
