The MD-80 and MD-90 families of jetliners are built on the same assembly line in Long Beach, Calif.
Conceived as another stretched variant of the DC-9, the MD-80 made its first flight as the DC-9 Super 80. The MD-80 Series of twinjets, featuring many advances in technology, was certified by the Federal Aviation Administration in August 1980 and entered airline service three months later.
The MD-90 is the newest member of twinjet family of aircraft that started with the DC-9. The MD-90 is an advanced midsized, medium-range airliner that was first delivered in 1995 and entered service two months later.
The MD-90's advanced flight deck includes an electronic flight instrument system, a full flight management system, a state-of-the-art inertial reference system, and LED dot-matrix displays for engine and system monitoring.
