Boeing 737 Next Generation

The Boeing 737 Next Generation, commonly abbreviated as 737NG, or 737 Next Gen, is a twin-engined narrow-body aircraft produced by Boeing Commercial Airplanes. Launched in 1993 as the third-generation derivative of the Boeing 737, it has been produced since 1997. The 737NG is an upgrade of the 737 Classic (–300/–400/–500) series. Compared to the 737 Classic, it has a redesigned wing with a larger area, a wider wingspan, greater fuel capacity, higher maximum takeoff weight and longer range. It has CFM International CFM56-7 series engines, a glass cockpit, and upgraded and redesigned interior configurations. The series includes four variants, the –600/–700/–800/–900, seating between 108 and 215 passengers. The 737NG's primary competition is the Airbus A320 family.
