Introduction

The McDonnell Douglas MD-80 is a series of five-abreast single-aisle airliners developed by McDonnell Douglas. It was produced by the developer company until August 1997 and then by Boeing Commercial Airplanes. The MD-80 was the second generation of the DC-9 family, originally designated as the DC-9-80 (DC-9 Series 80) and later stylized as the DC-9 Super 80 (short Super 80). Stretched, enlarged wing and powered by higher bypass Pratt & Whitney JT8D-200 engines, the aircraft program was launched in October 1977. The MD-80 made its first flight on October 18, 1979, and was certified on August 25, 1980. The first airliner was delivered to launch customer Swissair on September 13, 1980, which introduced it into service on October 10, 1980.

Keeping the fuselage cross-section, longer variants are stretched by 14 ft (4.3 m) from the DC-9-50 and have a 28% larger wing. The larger variants (MD-81/82/83/88) are 148 ft (45.1 m) long to seat 155 passengers in coach and, with varying weights, can cover up to 2,550 nautical miles [nmi] (4,720 km; 2,930 mi). The later MD-88 has a modern cockpit with EFIS displays. The MD-87 is 17 ft (5.3 m) shorter for 130 passengers in economy and has a range up to 2,900 nmi (5,400 km; 3,300 mi).

The MD-80 series initially competed with the Boeing 737 Classic and then also with the Airbus A320ceo family. Its successor, introduced in 1995, the MD-90, was a further stretch powered by IAE V2500 high-bypass turbofans, while the shorter MD-95, later known as the Boeing 717, was powered by Rolls-Royce BR715 engines. Production ended in 1999 after 1,191 MD-80s were delivered, of which 116 aircraft remain in service as of August 2022.

A small note from me:

I’m having an exam later on, so I might post the work a bit slow, but I’ll try to post 1 to 2 works each week, since I only have 2 hours of free time and heavy HWs.

That’s it
