Wings: New airfoil section, 25% increase in area, 107' semi-span increase, 17' chord increase, raked wing-tip, larger inspar wingbox with machined ribs. Fuselage: Strengthened for increased tail loads and design weights, new wing-body strake. While once the domain of just wide body aircraft, FANS is now becoming required capability on some Boeing 737's in commercial use.Įngines: FADEC controlled CFM56-7, 2.5deg nozzle tilt, redesigned struts, improved nacelles with increased airflow and improved noise treatment, 7% more fuel efficient than CFM56-3. Performance: Faster cruise M0.78, Higher ceiling 41,000ft, Lower take-off & approach speeds, Higher MTOW, lower fuel burn.īoeing has developed a self-paced, 737 based Future Air Navigation System (FANS) course. The main differences of the 737 Next Generation (NG) are as follows. This became the 737-700, 22cm (9in) longer than the original 737-300, seating up to 149.
