717 Airliner

The Boeing 717 is a twin-engine, single-aisle jet airliner, developed for the 100-seat market. The airliner was designed and originally marketed by McDonnell Douglas as the MD-95, a derivative of the DC-9 family. Capable of seating up to 134 passengers, the 717 has a design range of 2,060 nautical miles (3,820 km). It is powered by two Rolls-Royce BR715 turbofan engines mounted at the rear of the fuselage.

The first order for the airliner was placed with McDonnell Douglas in October 1995 by ValuJet Airlines (later AirTran Airways). With McDonnell Douglas and Boeing merging in 1997 prior to production, the airliner entered service in 1999 as the Boeing 717. Production of the Boeing 717 ceased in May 2006 after 156 were built. As of July 2018, 148 Boeing 717 aircraft were still in service.

Design

The 717 features a two-crew cockpit that incorporates six interchangeable liquid-crystal-display units and advanced Honeywell VIA 2000 computers. The cockpit design is called Advanced Common Flightdeck (ACF) and is shared with the MD-10 and MD-11. Flight deck features include an Electronic Instrument System, a dual Flight Management System, a Central Fault Display System, and Global Positioning System. Category IIIb automatic landing capability for bad-weather operations and Future Air Navigation Systems are available. The 717 shares the same type rating as the DC-9, such that the FAA approved transition courses for DC-9 and analog MD-80 pilots that could be completed in 11 days

The Douglas World Cruiser (DWC) was developed to meet a requirement from the United States Army Air Service for an aircraft suitable for an attempt at the first flight around the world. The Douglas Aircraft Company responded with a modified variant of their DT torpedo bomber, the DWC.
