Douglas developed the MD-90, an IAE V2500-powered derivative of the MD-80, to satisfy a customer need for a more environmentally - friendly 150-seat, short/medium range jet transport. The program was launched in late 1989 with requirements to:
significantly reduce community noise and engine emissions
improve aircraft fuel efficiency
make other technical improvements where cost effective for the customer.
The aircraft was certificated in November 1994 and entered airline service in April 1995. The MD-90 meets all of its technical requirements.
