The Boeing 767 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 original -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.
