The Boeing Next-Generation 737 Family
A More Advanced Wing Design Results in Longer Range and Higher Speed Capability
The 737-600/-700/-800/-900ER models incorporate a new, advanced-technology wing design that helps increase and improve fuel capacity and efficiency, both of which increase range.
- The total wing area is increased by 25 percent to 1,340 sq ft (125 sq m), providing 30 percent more fuel capacity for a total of 6,875 U.S. gallons (26,020 l).
- The advanced wing airfoil design provides an economical cruise speed of .78 Mach -- compared to .74 Mach for earlier 737 models.
- New-technology Blended Winglets are available on the 737-700, -800 and -900ER, and improve the performance of the 737.
- Range is increased to approximately 3,300 nautical miles (5,926 km), up to 900 nautical miles over earlier 737 models. This allows U.S. transcontinental flights and increases 737-route capability throughout the world.
The Next-Generation 737 airplanes are capable of cruising to a maximum altitude of 41,000 feet, compared to 37,000 feet for the 737-300/-400/-500 models, and 39,000 feet for the Airbus A320.
