Innovative Winglet Technology

  • Increase range, payload, and takeoff performance
  • Reduce fuel consumption and engine maintenance cost
  • Reduce noise
  • Increases residual value

Adding blended winglets to the highly efficient Next-Generation 737 wing boosts range, payload, takeoff and landing performance, and fuel economy. The improved performance allows pilots to use takeoff procedures that decrease wear and tear on engines and reduce community noise. The distinctive appearance of blended winglets can help differentiate the airline's brand. And as an additional benefit, winglets increase the airplane's residual value.

Superior Aerodynamic Design

Greater aerodynamic efficiency

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

Advanced Engine

One Engine Multiple Thrust Options Offer Market Versatility

Increased asset value from commonality

Strategic partnerships, spare parts pooling and fleet expansion are easier for the 737, thanks to a high degree of commonality and standardization. Asset value and liquidity are enhanced because all three Next-Generation 737s share the same efficient CFM56-7BE engine. A range of available thrust ratings allows airlines to match engine performance to operational requirements for longer time on-wing.

CFM56-7BE Engine Improvements

CFM International (CFM) is using advanced computer programs and three-dimensional design techniques to improve airfoils in the high- and low-pressure turbines for enhanced engine performance. In addition, CFM is improving engine durability and reducing parts count to achieve lower maintenance costs. The CFM56-7BE engine enhancement program entered airline service in mid-2011 to coincide with Boeing Next-Generation 737 airframe improvements.

The CFM56-7BE-powered Next-Generation 737 enhanced airplane/engine combination provides a two-percent improvement in fuel consumption, which equates to a two-percent reduction in carbon emissions.

Engine performance improvements lower fuel consumption by approximately 1%.
  • Improved high pressure turbine
  • Optimized low pressure turbine
  • Improved primary nozzle and plug
  • Refined aft strut fairing heat shield

Advanced Flight Deck

Innovative Flight Deck Technologies

First to demonstrate flight deck technology advantages

The Next-Generation 737 is leading the way in the development and implementation of flight deck technologies that will enable the aviation industry to meet the strong demand for air transport. No airplane has gained as much operational experience using technologies such as head-up display (HUD), vertical situation display, Global Navigation Satellite System (GNSS) Landing System (GLS) and Required Navigation Performance (RNP). These systems enhance safety, and pilots can fly more stable and precise paths with little or no new ground infrastructure. Air traffic controllers can grant a suitably equipped Next-Generation 737 the most direct and economical routes and clearance to land and takeoff under weather conditions that 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.

RNP Benefits

The first commercial airplane certified for RNP of 0.10 nautical miles

With Required Navigation Performance (RNP) certified at navigation precision of 0.10 nautical miles, the Next-Generation 737 qualifies for the most economical routes in busy airspace and the most direct approaches to runways restricted by noise regulations or terrain. Able to fly precise, preselected, 3D RNP flight paths without ground-based navigational aids, the Next-Generation 737 can maintain punctual schedules while other airplanes follow less efficient flight paths, circle in holding patterns, divert to other airports or stay on the ground. RNP capability delivers immediate operational advantages and supports evolving efforts to minimize flight delays and improve airspace utilization.

The Next-Generation 737 is the first airplane in its class certified to meet 0.10 nmi RNP.

Advanced Structure

Better Structural Efficiency

Next-Generation 737 is the first single-aisle jetliner designed concurrently as a family using 100% 3D digital design and manufacturing technology.

Higher Quality Assembly

Improved Servicing and Maintenance

Passenger Experience

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.

Continuous Innovation

Proven Performance


More range with more Payload

Superior range enables the Next-Generation 737 to serve more markets, with a full revenue payload. All three 737 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 a route — virtually without concern about range limitations — gives airlines unparalleled ability to match capacity to actual demand and to respond to near- and long-term demand fluctuations.


Next-Generation 737 is More Efficient

The Next-Generation 737 was developed by listening to our 737 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 Next-Generation 737s are less likely to experience schedule delays due to mechanical issues.

Next-Generation 737 is designed for maintainability
  • Next-Generation 737 was designed with the latest technology and is the industry leader in reliability.
  • More than 20 airlines participated in defining design solutions to meet operational maintenance needs.
  • The maintenance program was designed under MSG-3 Rev 2 requirements to optimize maintenance tasks.
  • Maintainability by design approach utilizes 100% digital design to verify access and removability.
  • Fuel efficient engines stay on-wing longer than any other single aisle airplane engine in commercial aviation.
  • The Next-Generation 737 design offers a flexible maintenance program with longer check intervals and more revenue flying days.


With three sizes, the Next-Generation 737 family offers airlines unequaled opportunity to optimize capacity and performance to actual demand and range requirements, while maintaining the powerful economic advantages of a single-type fleet.

One airplane in three sizes

As new market opportunities develop, Next-Generation 737 operators can grow their fleets with a lower investment in parts, equipment, and training:

  • Common flight deck
  • Common engines
  • Common airframe spares
  • Common ground handling equipment

Environmentally Progressive

Quieter for the Community

Next-Generation 737 Family Noise Contours

Decreasing the noise of airplane arrivals and departures is an important measure of environmental performance, especially to communities near airports. The Next-Generation 737 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, 737 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 737 enjoys access to highly regulated airports, even during restricted hours of operation.

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. With improved fuel efficiency for significantly lower CO2 emissions, the Next-Generation 737 already meets future emissions standards and surpasses current standards for noise and NOx emissions. Boeing continues to apply technology advances to make the Next-Generation 747 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 Next-Generation 737 is well ahead of today's environmental standards. Beyond the economic benefits of thrifty fuel consumption, the Next-Generation 737 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 Next-Generation 737 achieve excellent fuel economy and low emissions in all emission categories.
