The 757's flight deck uses six Rockwell Collins CRT screens to display flight instrumentation, as well as an electronic flight instrument system (EFIS) and an engine indication and crew alerting system (EICAS).
In October 1979 the nose was widened and dropped to reduce aerodynamic noise by six d B, to improve the flight deck view and to give more working area for the crew for greater commonality with the 767, as the T-tail was substituted by a conventional tail earlier in the year.
Ultimately, about half of the aircraft's components, including the wings, nose section, and empennage, were produced in-house at Boeing facilities, and the remainder subcontracted to primarily U. Eastern Air Lines, the first 727 operator to take delivery of 757s, confirmed that the aircraft had greater payload capability than its predecessor, along with lower operating costs through improved fuel burn and the use of a two-crew member flight deck.
Each wing features a supercritical cross-section and is equipped with five-panel leading edge slats, single- and double-slotted flaps, an outboard aileron, and six spoilers.
The airframe further incorporates carbon-fiber reinforced plastic wing surfaces, Kevlar fairings and access panels, plus improved aluminum alloys, which together reduce overall weight by 2,100 pounds (950 kg).
In July 2017, a total of 738 Boeing 757 aircraft of all variants were in commercial service with operators Delta Air Lines (138), Fed Ex Express (96), United Airlines (91), American Airlines (84), UPS Airlines (75), Icelandair (26), DHL Air (21), and others with fewer aircraft of the type.
The first fatal event involving the aircraft occurred on October 2, 1990, when a hijacked Xiamen Airlines 737 collided with a China Southern Airlines 757 on the runways of Guangzhou Baiyun International Airport, China, killing 46 of the 122 people on board.
At the March 2015 International Society of Transport Aircraft Traders conference, Air Lease Corporation's Steven Udvar-Hazy predicted the 757 replacement as a more capable, clean-sheet 767-like twin-aisle airplane capable of taking off 7,000 feet (2,130 m) runways like New York La Guardia, and Tinseth is focused on 20% more range and more capacity than the 757-200.
The 757 is a low-wing cantilever monoplane with a conventional tail unit featuring a single fin and rudder.
The 757-300 has been operated by mainline carriers Continental Airlines (now part of United Airlines), Northwest Airlines (now part of Delta Air Lines), and Icelandair; other operators have included American Trans Air (the first North American operator), Government, military, and private customers have acquired the 757 for uses ranging from aeronautical testing and research to cargo and VIP transport.
