What You'll Learn
The 737-700 has a greater fuel capacity than the 737 Classic
The Boeing 737 has been in production for nearly 60 years, with four distinct generations: the Original, Classic, Next Generation (NG), and MAX. The 737-700 is part of the Next Generation series, which also includes the -600, -800, and -900. The Next Generation series offers improved performance and commonality with previous 737 models.
The 737 Classic series, which includes the -300, -400, and -500, was first introduced in 1984 with the 737-300. The Classic series was a transformation from earlier models, focused on increased capacity and better fuel efficiency. The main difference was the addition of new engines, with the 737-300 using CFM56 turbofan engines.
The 737 Next Generation series also features auxiliary fuel tanks in the cargo hold and winglets. The CFM56-7B Evolution nacelle, tested in 2009, was used on the new 737 Performance Improvement Package (PIP) that entered service in 2011. This improvement shaved at least 1% off overall drag and improved fuel burn by 2% on longer stages. Split Scimitar winglets, introduced in 2015 for the 737-700, produce up to a 5.5% fuel saving per aircraft compared to 3.3% for blended winglets.

The 737-700 has a range of 6,878 gallons of fuel
The Boeing 737-700 has a maximum fuel capacity of 6,878 gallons (26,035 litres). This is part of the Next Generation (NG) series, which also includes the 737-600, 737-800, and 737-900ER. The 737NG is an upgrade of the 737 Classic series, featuring a redesigned wing with a larger area, a wider wingspan, greater fuel capacity, higher maximum takeoff weight, and longer range. The 737NG series offers seating for between 108 and 215 passengers.
The 737-700 was first delivered to Delta Air Lines in July 2008, featuring Messier-Bugatti-Dowty's new carbon brakes. These brakes reduce the weight of the brake package by 550-700 pounds (250-320 kg), resulting in a 0.5% reduction in fuel burn. The 737-700 also features the CFM56-7B Evolution nacelle, which improves overall fuel burn by 2% on longer stages.
The 737-700 has the option of up to two auxiliary fuel tanks in the cargo hold, which can further extend its range. This feature is also available on the 737-600, 737-800, and 737-900ER. The 737-900ER, launched in July 2005, has a maximum seating capacity of 220 passengers.
The 737-700 is similar in dimensions to the Boeing Business Jet (BBJ), which is based on the 737-800. The BBJ features stronger wings and landing gear from the 737-800, as well as increased range through the use of extra fuel tanks. The BBJ was first rolled out on August 11, 1998, and 113 BBJ1s were delivered to customers.

The 737-700 has improved fuel efficiency with carbon brakes
The 737-700 is part of the Boeing 737 Next Generation (NG) series, which was launched in 1993 and produced from 1997 onwards. The 737NG is an upgrade of the 737 Classic series, with a redesigned wing, a wider wingspan, greater fuel capacity, higher maximum takeoff weights, and a longer range. The 737-700 has a seating capacity of between 108 and 215 passengers.
In terms of fuel efficiency, the 737-700 offers a notable improvement over its predecessor, the 737 Classic. The 737-700 is equipped with CFM International CFM56-7 series engines, which contribute to reduced fuel consumption. Additionally, Boeing offered Messier-Bugatti-Dowty's carbon brakes as an option for the Next-Gen 737s starting in July 2008. These carbon brakes are designed to replace the standard steel brakes, resulting in a significant weight reduction of 550 to 700 pounds (250 to 320 kg).
The weight savings from the carbon brakes directly contribute to improved fuel efficiency. For example, a 700-pound weight reduction on a 737-800 results in a 0.5% reduction in fuel burn. While the specific fuel burn improvement for the 737-700 with carbon brakes may vary, it is reasonable to expect a similar or proportional impact on fuel efficiency.
Furthermore, the 737-700's wing design also plays a role in its fuel efficiency. The redesigned wing on the 737NG series has a larger area and updated airfoil sections, contributing to enhanced aerodynamic performance and reduced drag. This, coupled with the carbon brakes, further contributes to the overall fuel efficiency of the 737-700.
In summary, the 737-700, as part of the 737 Next Generation series, offers improved fuel efficiency compared to its predecessor. The combination of CFM International CFM56-7 series engines, the redesigned wing, and the option of carbon brakes all contribute to reduced fuel consumption and improved operational efficiency. These advancements not only reduce fuel costs but also contribute to more environmentally sustainable operations.

The 737-700 has a CFM56-7 series engine
The 737-700 is part of the Next Generation (NG) group of aircraft, which also includes the 737-600, 737-800, and 737-900ER. These aircraft were a significant update to the previous 737 models, with redesigned wings and improved performance.
The 737-700 is powered by the CFM56-7 series engine, which is a high-bypass turbofan engine. This engine has a two-shaft or two-spool design, with a high-pressure and low-pressure turbine, each powered by its own turbine section. The CFM56-7 series is an upgraded version of the CFM56 engine, which has been serving the industry since the 1980s and is known for its reliability, fuel efficiency, and low maintenance costs.
The CFM56-7B engine, specifically, is manufactured by CFM International, a joint venture between General Electric (USA) and Safran. This engine variant offers improved aerodynamics and engine cooling, resulting in reduced maintenance costs and improved fuel consumption. The CFM56-7BE, also known as the CFM56-7B Evolution, further enhances these features and aims to reduce the overall part count.
The CFM56 engine family powers both the Airbus A320ceo and the Boeing Next-Generation 737 families of aircraft. With a thrust range of 18,500 to 34,000 pounds, these engines provide high performance and durability, contributing to the success of the 737-700 and other aircraft in their respective classes.

The 737-700 is part of the 737 Next Generation (NG) series
The 737-700 is indeed part of the 737 Next Generation (NG) series. The 737NG is a group of aircraft that includes the 737-600, 737-700, 737-800, and 737-900ER. The first NG to be introduced was the 737-700, which rolled out on December 8, 1996, and first flew on February 9, 1997. The 737NG series is a significant update to the previous Boeing 737 models, with improvements in performance and range.
The 737NG series features a redesigned wing with greater chord and an updated airfoil section, increasing the wing span by 16 feet (4.9 m) and the wing area by 25%. This redesign, along with new CFM56-7B engines, increased the 737's range by 900 nautical miles to over 3,000 nautical miles (5,600 km). The new wing design also improved takeoff and landing performance, reduced community noise, and increased total fuel capacity by 30%.
The 737-700, as part of the NG series, also features improved fuel efficiency. The addition of blended winglets, which stand approximately 8 feet (2.4 m) tall and are installed at the wing tips, helps to reduce fuel burn by reducing vortex drag. These winglets, along with other improvements, contribute to an overall fuel efficiency improvement of up to 5%.
The 737NG series offers enhanced strategic partnerships, spare parts pooling, and fleet expansion due to its high degree of commonality and standardization. All 737NGs share the same efficient CFM56-7BE engine, which provides improved engine performance and durability while reducing maintenance costs. The 737NG is also equipped with advanced navigation and situational awareness technologies, giving it access to routes and approaches unavailable to less advanced aircraft.
