Both The wide-body concept, which Airbus chosen to supply hydraulic pumps, aircraft are fitted with either Pratt & has incorporated into both the A300 and motorpumps, power transfer units and Whitney or General Electric turbofan the A31 0, has greatly increased the valves for the Airbus A300 and A31 0 engines which, combined with the operating efficiency of these aircraft over commercial jet airliners. Airbus Industry, high-lift wing design, make these aircraft earlier jet airliner designs. Because of a consortium comprised of cooperating two of the most efficient and economical its greater capacity for passengers and * airframe manufacturers from throughout jet airliners in use today.
