The Next-Generation 737-900ER (Extended Range) is the latest member of the 737 airplane family, the world's best-selling jetliner family. The higher-capacity, longer-range derivative of the 737-900 was launched on July 18, 2005 with an order for 30 airplanes from Indonesia's Lion Air.
The first delivery to Lion Air took place on April 27, 2007.
Aerodynamic and structural design changes such as an additional pair of exit doors and a flat rear pressure bulkhead increase interior volume. The airplane is capable of carrying up to 180 passengers in a two-class layout and is certified for up to 220 passengers in a one-class layout.
Other changes include:
- a two-position tailskid for improved takeoff and landing capability; a stronger wing to accommodate the 13,500 pound (6,100 kg) maximum takeoff weight increase;
- enhancements to the leading and trailing edge flap systems, also for improved takeoff and landing capability;
- and optional Blended Winglets and auxiliary fuel tanks that increase the range of the 737-900ER to 3,235 nautical miles (5,990 km).
The 737-900ER has substantial economic advantages over heavier competing models including 7 percent lower trip cost and 5 percent lower seat-mile cost.
The 737-900ER shares the same performance attributes of the other models of the Next-Generation 737 family (737-600, 737-700 and 737-800): reliability, lower maintenance costs, lower operating costs and optional state-of-the-art flight deck systems such as Head-Up Display (HUD), Global Positioning Landing System and Vertical Situation Display.
The 737-900ER also has the same advanced-technology wing design that helps increase fuel capacity and efficiency. The advanced wing airfoil design provides an economical cruise speed of .791 Mach (525 mph).
The 737-900ER model is powered by new CFM56-7BE engines produced by CFM, a joint venture of General Electric Co. of the U.S. and Snecma of France. The engines meet the latest noise regulations and, through a tech insertion package introduced in 2007 and further refinements in 2011, have reduced fuel use and increased engine time on wing because the engine burns cooler.
