American Airlines was the first US major carrier to order the MD-80 when it leased twenty 142-seat aircraft from McDonnell Douglas in October 1982 to replace its Boeing 727-100s. It committed to 67 firm orders plus 100 options in March 1984, and in 2002 its fleet peaked at more than 360 aircraft, 30% of the 1,191 produced.
The Pratt & Whitney JT8D is a low-bypass (0.96 to 1) turbofan engine introduced by Pratt & Whitney in February 1963 with the inaugural flight of the Boeing 727.It was a modification of the Pratt & Whitney J52 turbojet engine which powered the US Navy A-6 Intruder and A-4 Skyhawk attack aircraft.
The 727 is equipped with a retractable tailskid that is designed to protect the aircraft in the event of an over-rotation on takeoff. The 727's fuselage has an outer diameter of 148 inches (3.8 m). This allows six-abreast seating (three per side) and a single aisle when 18-inch (46 cm) wide coach-class seats are installed.
The MD-80 series, the first derivative or the second generation of the DC-9 family, entered service in 1980.The aircraft series was originally designated as Series 80 or stylized as the Super 80, [5] which was a 14 ft 3 in (4.34 m) lengthened Series 50 with a higher maximum take-off weight (MTOW) and higher fuel capacity, as well as next-generation Pratt and Whitney JT8D-200 series engines and ...
[26] [27] It was a lengthened DC-9-50 with a higher maximum takeoff weight (MTOW), a larger wing, new main landing gear, and higher fuel capacity. [28] The MD-80 series features a number of variants of the JT8D turbofan engine that had higher thrust ratings than those available on the original DC-9 series. [29]
It would have carried 150 passengers and was touted as the successor to the successful Boeing 727. [1] It was initially planned to enter service in 1992. [1] This was intended as a highly fuel-efficient aircraft employing new technologies, but it was postponed indefinitely as the price of oil dropped during the 1980s.
Laundry detergents can provide an easier way to do your laundry, but we were skeptical about how well they work. We put nine popular brands to the test to see how they performed.
Airbus A320 (foreground) and Boeing 737-900 (background), both narrow-bodies. Historically, beginning in the late 1960s and continuing through the 1990s, twin engine narrow-body aircraft, such as the Boeing 737 Classic, McDonnell-Douglas MD-80 and Airbus A320 were primarily employed in short to medium-haul markets requiring neither the range nor the passenger-carrying capacity of that period's ...
