The aerodynamic efficiency of the 737NG wing increases the speed at which the airplane can cruise economically. Improved takeoff and landing performance translates to better performance at high-altitude airports and on short runways.

Commonality increases versatility

By using the same efficient CFM56-7BE engine, all 737NG models have a high degree of commonality and standardization, providing opportunities for strategic partnerships, spare parts pooling, and fleet expansion. With a range of available thrust ratings, airlines can match engine performance to operational requirements for longer time on-wing.

Innovative flight deck technologies

The 737NG flight deck incorporates a number of new technologies that enhance safety and allows air traffic controllers to grant suitably equipped 737NGs the most direct, economical routes as well as clearance to land and takeoff when weather conditions would require other airplanes to divert or stay on the ground.

Familiar look and feel

All Boeing flight decks feature large-displacement flight controls. Controls are interlinked so that both pilots are immediately aware of any control input — whether from the other pilot or from the autopilot. Flight deck automation can smooth the flight and relieve the flight crew of many routine tasks, while keeping pilots aware of the airplane's situation. Pilots always have full authority to fly the airplane and to make crucial flight decisions.

These flight deck technologies are offered as optional features. This allows the customers to design their flight deck configuration to their specific requirements while minimizing weight and maintenance costs.

The spacious, comfortable look and feel of the 737 Boeing Sky Interior is further enhanced by soft LED lighting, thoughtfully balanced for leisure, work or rest. The lighting can gently simulate a full flying day for longer flights, gradually changing through a spectrum of lighting from day into night. Because LED lights have no filament, they last 10 to 20 times longer than incandescent lights that are used on airplanes today. The LED lighting also generates less heat than conventional cabin lighting.

More range with more payload

The 737NG is able to serve more markets with a full revenue payload. All three 737NG models can fly transcontinental distances and all can be equipped and certified for ETOPS flights. The ability to assign any of the three airplane sizes to most routes gives airlines unparalleled ability to match capacity to actual demand and to respond to near- and long-term demand fluctuations.

Efficiency

The 737NG was developed by listening to our customers to understand where we could improve all aspects of 737 operations. That collaboration allowed us to identify the right new technologies to greatly reduce maintenance costs. Travelers benefit directly from the dramatically lower maintenance requirements, as passengers on 737NGs are less likely to experience schedule delays due to mechanical issues.

NextMaintainability

The 737NG was designed with the latest technology, with more than 20 airlines participating in defining designs that meet operational maintenance needs. The maintenance program was designed under MSG-3 Rev 2 requirements to optimize maintenance tasks, with an approach that utilizes a 100% digital design to verify access and removability. The 737NG design offers a flexible maintenance program with longer check intervals and more revenue flying days.

The 737NG family offers airlines opportunity to optimize capacity and performance to actual demand and range requirements, while maintaining the powerful economic advantages of a single-type fleet. Operators can grow their fleets with a lower investment in parts, equipment, and training because 737NGs share a:

737NG family noise contours

Decreasing the noise of airplane arrivals and departures is an important measure of environmental performance, especially to communities near airports. The 737NG is quiet enough on takeoff and landing to give operators maximum flexibility to schedule flights into and out of restrictive airports, including London's stringently regulated Heathrow Airport.

Noise stays within the boundary of the airport

At most airports, 737NG 85-dBA noise levels stay within the airport boundary. This is the approximate noise of a truck driving along a highway. Because community noise impact is low, the 737NG enjoys access to highly regulated airports, even during restricted hours of operation.

Environmentally progressive cleaner, quieter and more efficient operations

People want to feel that they can be environmentally responsible when they fly, whether it is to visit with family and friends, to conduct business or to explore new places. The 737NG already meets future emissions standards and surpasses current standards for noise and NOx emissions. Boeing continues to apply technology advances to make the 737NG even cleaner, quieter and more fuel-efficient. Because when it comes to the environment, less is more.

Clean flying and a clean conscience

Airlines and passengers can rest assured that the 737NG is well ahead of today's environmental standards. Beyond the economic benefits of thrifty fuel consumption, the 737NG uses resources sparingly and produces less carbon dioxide per seat than other airplanes in its class.

Clean by all emission metrics

Structural efficiency, an advanced wing and the latest engine technology help the 737NG achieve excellent fuel economy and low emissions in all emission categories. All 737NG family members beat NOx emission targets established by the International Civil Aviation Organization (ICAO) Committee on Aviation Environmental Protection (CAEP)/6 by a margin of at least 20 percent.

ISO 14001 certification planned for all manufacturing sites.

Our environmental commitment spans the entire life cycle of our jetliners—from the offices where airplanes are designed, through the manufacturing process, to the operation and maintenance of the airplane in commercial service, and ultimately to the recycling of resources from retired aircraft. As a recognized Lean+ innovator, Boeing Commercial Airplanes has or will achieve certification for all manufacturing sites under stringent ISO environmental management standards.
