McDonnell Douglas MD-11 cutaway

The McDonnell Douglas MD-11 is a three-engine medium- to long-range widebody jet airliner, manufactured by McDonnell Douglas and, later, by Boeing Commercial Airplanes. Based on the DC-10, it features a stretched fuselage, increased wingspan with winglets, refined airfoils on the wing and smaller tailplane, new engines and increased use of composite materials. Two of its engines are mounted on underwing pylons and a third engine at the base of the vertical stabilizer. It also features an all-digital glass cockpit that decreases the flight deck crew from the three required on the DC-10 to two by eliminating the necessity for a flight engineer

The A350-900 is the first model scheduled to enter service (EIS) in 2013 and seats 314 passengers in a 3-class cabin 9-abreast layout. It has a standard design range target of 15,000 km (8,100 nmi). Airbus says that the A350-900 will have a decrease of 16% MWE per seat, a 30% decrease in block fuel per seat and 25% better cash operating cost against the Boeing 777-200ER. The -900R and -900F variants also have been proposed but not yet launched. These are to feature the higher engine thrust, strengthened structure and landing gear of the -1000. Range of the "standard" A350-900R was estimated to 17,600 km (9,500 nmi), which would be boosted to about 19,100 km (10,315 nmi) by these design improvements to compete with the Boeing 777-200LR and be capable of Non-stop flight from London-Heathrow to Auckland. The -900 is designed to compete with the Boeing 777-200ER and replace the Airbus A340-300.
