The Boeing Next-Generation 7373-800

The Boeing 737-800 is the best-selling version of the successful Next-Generation 737 family.

Known for its reliability, fuel efficiency and economical performance, the 737-800 is selected by leading carriers throughout the world because it provides operators the flexibility to serve a wide range of markets. The single-aisle jet, which can seat between 162 to 189 passengers, can fly 260 nautical miles farther and consume 7 percent less fuel while carrying 12 more passengers than the competing model.

The 737-800 was launched on Sept. 5, 1994, with commitments from customers for more than 40 airplanes. The first delivery was to German carrier Hapag-Lloyd in spring 1998. On March 13, 1998, the 737-800 earned type certification from the U.S. Federal Aviation Administration. JAA type validation of the 737-800 followed on April 9, 1998.

The 737-800, along with the other models of the Next-Generation 737 family (737-600, 737-700 and 737-900ER), offers a modern flight deck using the latest large flat-panel-display technology. Airlines can choose to provide their flight crews with either the latest display format, common with the 777, or opt for data format commonality with earlier 737 models.

The flight deck is equipped with optional technologies such as vertical situation display, which shows the current and predicted flight path of the airplane and indicates potential conflicts with terrain; and Head-up Display, which provides pilots with "eye-level" flight and safety information. Leading-edge display and flight-management software allows the airplane to fly the most restricted navigation routes through use of industry leading Required Navigation Performance. The Next-Generation 737 is the first commercial jet certified for Ground Positioning System landings, which use satellite technology to make landings more efficient, accurate, and environmentally friendly.

Advanced Engine Technology

In April 2009, Boeing and CFM introduced the New CFM56-7BE engine enhancements program to coincide with 737 airframe improvements. The combination reduces fuel consumption by two percent.

CFM's engine hardware changes will improve airflow, and the engine will run at cooler temperatures resulting in a one percent reduction in fuel consumption. Boeing's airplane structural improvements will reduce drag, reducing fuel use by about one percent. The combined improvements also equal a two percent reduction in carbon emissions.

Depending on the engine's thrust rating, the new engine will provide up to four percent lower maintenance costs.

The CFM56-7BE engine will be rolled into Boeing's production line in mid-2011. Boeing will introduce its airframe improvements into production as they become available, and all will be in place by early-2012.

The 737-800 incorporates an advanced-technology wing design that helps increase fuel capacity and efficiency, both of which increase range. The advanced wing airfoil design provides an economical cruise speed of .789 Mach (530 mph) - compared to .745 Mach for earlier 737 models. The Next-Generation 737 airplanes are capable of cruising to a maximum altitude of 41,000 feet, compared to 39,000 feet for the competition.

In addition, advanced-technology Blended Winglets are offered as a production option on the 737-800. These eight-foot long wingtip extensions enhance range, fuel efficiency and take-off performance while lowering carbon emissions, engine maintenance costs and noise. Performance benefits include fuel consumption and emissions reductions of up to 3.5 percent.

737 Boeing Sky Interior Now in Service

Drawing from years of passenger research, the 737 Boeing Sky Interior features new, modern sculpted sidewalls and window reveals that draw passenger eyes to the airplane's windows, giving passengers a greater connection to the flying experience. The new design offers larger, pivoting overhead stowage bins that add to the openness of the cabin. The bins give more passengers room to store a carry-on roll-aboard near their own seat, adding both extra convenience and extra leg room.

Boeing redesigned reading-light switches so passengers can find them more easily and avoid accidentally pressing the flight-attendant call button.

Speakers integrated into each row's passenger-service unit will improve sound and clarity of public address operations, while the new integrated air vent and improved noise-dampening materials will reduce overall cabin noise.

Deliveries of the new 737 Boeing Sky Interior began in late 2010.
