McDonnell Douglas MD-80

The McDonnell Douglas MD-80 series is a family of twin-engine, short- to medium-range, single-aisle commercial jet airliners. The MD-80 series was lengthened and updated from the DC-9. The MD-80 family can seat from 130 to 172 passengers depending on variant and seating configuration.

The MD-80 series was introduced into commercial service on October 10, 1980 by Swissair. The series includes the MD-81, MD-82, MD-83, MD-87, and MD-88. These all have the same fuselage length except the shortened MD-87. The series was followed into service in modified form by the MD-90 in 1995 and the MD-95/Boeing 717 in 1999.

Design and development

Background

Douglas Aircraft developed the DC-9 in the 1960s as a short-range companion to their larger DC-8. The DC-9 was an all-new design, using two rear fuselage-mounted turbofan engines, and a T-tail. The DC-9 has a narrow-body fuselage design with five-abreast seating, and holds 80 to 135 passengers depending on seating arrangement and aircraft version.
