Boeing 757
The Boeing 757 is an American narrow-body airliner that was designed and built by Boeing Commercial Airplanes. The 757 has a 2,000 sq ft supercritical wing for reduced aerodynamic drag and a conventional tail. It keeps the 707 cross-section and its two-crew glass cockpit has a common type rating with the concurrently designed 767. The jetliner is powered by 36,600–43,500 lbf Rolls-Royce RB211 or Pratt & Whitney PW2000 underwing turbofan engines.
About Boeing 757 in brief
The Boeing 757 is an American narrow-body airliner that was designed and built by Boeing Commercial Airplanes. The 757 has a 2,000 sq ft supercritical wing for reduced aerodynamic drag and a conventional tail. It keeps the 707 cross-section and its two-crew glass cockpit has a common type rating with the concurrently designed 767. The jetliner is powered by 36,600–43,500 lbf Rolls-Royce RB211 or Pratt & Whitney PW2000 underwing turbofan engines for a 255,000–273,000 lb MTOW. It was commonly used for short and mid-range domestic routes, shuttle services, and transcontinental U.S. flights. In July 2017, 666 were in airline service; Delta Air Lines was the largest operator with 127 aircraft. The airliner has recorded eleven hull-loss accidents, including eight fatal crashes, as of June 2019. It has been customized by private and government operators as VIP carriers like the US C-32. Boeing offered the largest 737 NG variants as a successor to the 757 in 2004, but the 737 NG did not receive any orders and was dropped; 737s later fulfilled its role as a narrow- body airliner. The then-named 7N7, a twinjet successor for the 727, received its first orders in August 1978. The prototype completed its maiden flight on February 19, 1982 and it was FAA certified on December 21, 1982. Eastern Air Lines placed the original 757-200 in commercial service on January 1, 1983.
A package freighter variant entered service in September 1987 and a combi model in September 1988. The stretched 7 57-300 was launched in September 1996 and began service in March 1999. After 1,050 had been built for 54 customers, production ended in October 2004, while Boeing offered a successor, the 737NG, to replace the 7 57 as the next-generation passenger jet. The 737NG was not intended to be more efficient and capable than the preceding 727, but to be a more capable and more efficient aircraft than the earlier 727-200. It can haul a 72,210 lbs payload over 2,935 nmi. Passenger 757s have been modified for cargo use as the special freighter. Major customers for the757 included U. S. mainline carriers, European charter airlines, and cargo companies. United Airlines provided input for the proposed 7 27-300, which Boeing was poised to launch in late 1975, but lost interest after examining development studies for the sevenN7. The aircraft was officially designated the 7N200 version in March 1979, when Boeing officially announced the aircraft was to be the 756-100. It is the first aircraft to be officially designated as the 755-100, when the aircraft became the 758-100 and the 759-100-200-300-400-500-600-600.
