The Boeing 767 DELTA AIRLINES is a mid-size wide-body twin-engine airliner produced by Boeing Commercial Airplanes. Versions of the 767 can carry between 181 and 375 passengers. The first wide-body twinjet produced by Boeing, the 767 was conceived and designed in tandem with the narrow-body Boeing 757 twinjet. Both airliners share design features and flight decks, enabling pilots to obtain a common type rating to operate the two aircraft. The 767 was the first Boeing wide-body airliner to enter service with a two-person crew flight deck, eliminating the need for a flight engineer. Following in-service indications of its twinjet design reliability, the 767 received regulatory approval allowing extended transoceanic operations beginning in 1985.
Boeing 767 models have a range of 5,200 to 6,590 nautical miles (9,400 to 12,200 km) depending on variant and seating. The 767 has been produced in three fuselage lengths. The original 767-200 first entered into airline service in 1982, followed by the 767-300 in 1986, and the 767-400ER in 2000. Extended range versions of the -200 and -300 models, the 767-200ER and 767-300ER, have been produced with added payload and operating distance capability. The 767-300F, a production freighter version, entered service in 1995.
Through the 1990s, the Boeing 767 became commonly operated on medium- to long-haul routes, and the aircraft has ranked as the most widely used airliner for transatlantic flights between the United States and Europe. The aircraft is regarded as an ETOPS pioneer, being the first to receive 180-minute approval by the FAA. There have been over 1,000 Boeing 767s ordered with over 990 delivered as of 2010. The -300/-300ER models are the most popular variants, accounting for approximately two-thirds of all 767s ordered. There were 863 Boeing 767s in service with over 40 airlines as of July 2010.
