Airbus A318

The A318, also known as the "Mini-Airbus" or "baby bus", is the smallest member of the A320 family, and the smallest Airbus of any kind. It originated from the AVIC andAirbus Industrie Asia cooperation programme AE31X. During development, it was known as the "A319M5," thus indicating its history as a direct derivative of the A319. "M5" indicates "minus five fuselage frames." The aircraft is six metres shorter and four tonnes lighter than the A320. To compensate for the reduced moment arm it has a larger vertical stabilizer, making it 80 centimetres taller than the other A320 variants. Pilots who are trained on the other variants may fly the A318 with no further certification, since it features the same type rating as its sister aircraft.

Airbus A319

The A319 is a shortened, minimum change version of the A320. With virtually the same fuel capacity as the A320-200, and fewer passengers, the range with 124 passengers in a two-class configuration extends to 3,600 nautical miles (6,700 km), the highest in its class. A319s are among the most popular variants of the A320 family. In 2003 EasyJet took delivery of A319s with smaller galleys (as EasyJet does not serve meals on some of its shorter flights) and 156 seats in a single class configuration. To satisfy evacuation regulations, additional over-wing exits were included. Easyjet later became the largest A319 operator.

Airbus A320

The A320 series has two variants, the A320-100 and A320-200. Only 21 A320-100s were ever produced; these aircraft, the first to be manufactured, were delivered only to Air Inter (an airline later acquired by Air France) and British Airways (as a result of an order from British Caledonian Airways made prior to its acquisition by British Airways). The A320-200 features wingtip fencesand increased fuel capacity over the A320-100 for increased range; other than that differences are minimal. The last five A320-100 aircraft, operated by British Airways, were disposed of at the end of 2007. Typical range with 150 passengers for the A320-200 is about 2,900 nautical miles (5,400 km). It is powered by two CFMI CFM56-5 or IAE V2500 with thrust ratings between 25,500 to 27,000 pounds force (113 kN to 120 kN). The direct Boeing competitor is the 737-800.

Boeing 737-600

The 737-600 replaced the 737-500 in Boeing's line up, and was also intended to replace airlines' DC-9s. The 737-600 was launched by Scandinavian Airlines System in 1995 with the first aircraft delivered on September 18, 1998. The -600 is the only Boeing 737 still in production that does not include winglets as an option. WestJet was to be the Boeing launch customer for the 737-600 with winglets, but announced in their Q2 2006 results that they were not going to move ahead with those plans.

The 737-600 competes with the Airbus A318, Embraer 195, and the upcoming Bombardier CSeries jet. A total of 69 -600s have been delivered with no unfilled orders as of 2009.

Boeing 767-400ER

The 767-400ER is the final extended variant and was launched in 1997 on an order for Delta Air Lines and Continental Airlines to replace their aging Lockheed L-1011 andMcDonnell Douglas DC-10 fleets, respectively, following both airlines rejection of Boeing's previous 777-100X proposal. Other airlines also placed orders, but these were eventually canceled or converted to other Boeing models.^[46] The 767-400ER is a major development over the 767-300. The -400ER was stretched 21.1 ft (6.43 m) from the -300 for a total of 201.4 ft (61.4 m). It also featured a new glass cockpit, redesigned wings with a wingspan increase of 14.3 ft (4.36 m) over the previous two variants, larger passenger windows, new passenger cabin and redesigned landing gear. The -400ER is the only 767 variant to also feature "raked" wingtips for increased fuel efficiency. Its first flight was on October 9, 1999,^[47] and entered into service with Continental Airlines on September 14, 2000. This variant is only available as the 767-400ER, as there was no 767-400 variant. However it has less range than the other two ER variants.

Boeing 777-200ER

The 777-200ER ("ER" for Extended Range), the B-market version of the -200, was originally known as the 777-200IGW for its increased gross weight. The -200ER features additional fuel capacity and an increased maximum takeoff weight (MTOW) over the -200. Aimed at international airlines operating transatlantic routes, the -200ER's maximum range is 7,700 nautical miles (14,300 km). In addition to breaking the eastbound great circle "distance without landing" record, the -200ER also holds the record for the longest ETOPS-related emergency flight diversion (177 minutes under one engine), on a United Airlines flight carrying 255 passengers on March 17, 2003, over the Pacific Ocean.

The first -200ER was delivered to British Airways on February 6, 1997. As of April 2010, -200ER deliveries to 33 different customers numbered 413, ranking the -200ER as the best-selling variant of the twinjet to date. As of July 2009, 407 aircraft were in airline service. The competing aircraft from Airbus is the A340-300

Boeing 747-400F

The 747-400F (Freighter) is an all freight version which uses the fuselage design of the 747-200F. The aircraft's first flight was on May 4, 1993 and it entered service withCargolux Airlines on November 17, 1993. Major customers include Atlas Air, Cargolux, China Airlines, Korean Air, Nippon Cargo Airlines, Polar Air Cargo, and Singapore Airlines. The -400F can be easily distinguished from the passenger -400 by its shorter upper-deck hump.

The 747-400F has a main deck nose door and a mechanized cargo handling system. The nose door swings up so that pallets or containers up to 40 ft (12 m) can be loaded straight in on motor-driven rollers. An optional main deck side cargo door (like the 747-400M (Combi) allows loading of dimensionally taller cargo modules.

Boeing has delivered 126 Boeing 747-400F aircraft with no unfilled orders as of November 2009.The last -400F was delivered to Nippon Cargo Airlines.
