One of the main production differences with the NG is the single moving assembly line, this has the capacity to produce 21 aircraft a month with a flow time of just 13 days. The NG's have 33% fewer parts than the Classics which reduces. Systems: Most systems developed particularly: electrics, powerplant & navigation. Flightdeck: 6 programmable LCD's, replacing EFIS CRT displays and most conventional instruments. Main Gear: Longer to reduce tailstrike risk, one piece titanium gear beam, 43.5' tyres, digital antiskid. Nose Gear: Stroke increased 3.5' to relieve higher dynamic loads and wheelwell extended 3' forward.

Tail: 4ft 8in taller, 60 sq ft root insert, modified rudder, segmented rudder seals, digital yaw damper.įlight Controls: Increased elevator PCU capability, aileron and tab span increase, new double slotted continuous span flaps, new leading edge Krueger flaps, additional slat, additional spoiler. Fuel Tanks: Main tanks smaller at 3900kg each but centre tank much larger giving total fuel capacity of 20,800kg. 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. Next Generation The Boeing 737-X programme was launched on 29 June 1993, with a 63 aircraft order from Southwest Airlines for the 737-300X.
