The Boeing 737 is a popular, twin-engine, short- to medium-range aircraft that stands out by its simplicity, reliability and low operating costs and maintenance.
The first Boeing 737-700 was released in 1998, to Southwest and after that, more than 2,240 Next Generation 737s aircrafts have been sold in worldwide.
The 737-700 and -600 are the smaller members of Boeing’s popular Next Generation 737-600/700/800/900 category and the the 737-700 aircraft replaced the 737-300 variant in Boeing’s lineup, and also its direct challenger - the A319.
Another aricraft model, Boeing 737-700C is a convertible version, where the seats can be detached, also the airplane has a large door on the left side, being used for transporting cargo.
In 31 January 2006, Boeing put on sale one of the newest models of the popular Next-Generation 737 family, the 737-700ER model.
This airplane is a passenger version of the BBJ1 and 737-700IGW. It combines the 737-700 fuselage with the wings and landing gear of a 737-800.
This new aircraft model offers a range of 5,510 nautical miles (the longest range for a 737), with seating for 126 passengers in a traditional 2-class configuration.
All Nippon Airways, Japan’s second-biggest carrier, is to pioneer the model in Asia with a daily service between Tokyo and Mumbai. ANA’s service, supposed to be the first all-business class route connecting to a increasing country, was to begin in September 2007 and use a Boeing 737-700ER equipped with an extra fuel tank and 36 seats.
Boeing 737-700 Exterior
The airplane’s versatility, range performance and low operating costs can serve all new airline business necessities including low-cost carriers that wish to increase their market reach across the Atlantic Ocean and traditional carriers that wish to compete in niche markets such as all-premium-class service.
The 737’s new wing has greater chord, span and wing area, while the tail surfaces are also larger. The 2.4m (8ft) high winglets first developed for the Boeing Business Jet development are now offered as an option on the 737-700 (and -800).
There are some important characteristics that should be mentioned :
- the new carbon brakes manufactured by Messier-Bugatti, now certified by the Federal Aviation Administration, weigh 550–700 lb (250–320 kg) less than the steel brakes;
- wing tip extensions, called Winglets, have been added to the Boeing 737-700 wing layout to extend range, increase payload and also to save fuel. The Winglet measures are: 8-ft long (2.44 meters) and 4-ft (1.22 meters) in width;
The Boeing Business Jet, designed for corporate and VIP applications, is a special, high-performance derivative of the 737-700.
The Boeing 737-700C model can transport up to 18,200 kilograms of cargo and fly up to 2,880 nautical miles (5,330 kilometers).This aircraft has strengthened wings identical to those on the Boeing Business Jet (BBJ), it also has a new main-deck cargo door and a new cargo handling system.
The 737-700C permits aircrafts to alternate between passenger and cargo layouts on a daily, weekly or seasonal basis depending on market necessities.
The Boeing 737-700ER has the same aerodynamic and structural changes as the successful BBJ, offered through the Boeing Business Jets Program. This aircraft has additional fuel capacity that permits it to fly up to 2,280 nautical miles farther than the original Boeing 737-700.

Boeing 737-700 Interior
The customer can install specific interior configurations and the resulting aircraft performs and has some commonalty, as the landing gear for example.
The 737-700ER offers the ultimate in flexibility when it comes to seating arrangements. The twinjet can seat 48 passengers for premium service; or up to 126 passengers in a two-class configuration.
The 737-700, the basis for the Boeing business jet (BBJ), is the midsize version transporting 126 to 149 passengers, in a two-class or one-class arrangement. This aircraft was designed for long-range commercial applications.
Boeing and General Electric formed a joint venture – Boeing Business Jets – in 1996 to produce the BBJ with nearly three times the cabin space of traditional long-range business jets at a comparable price. The BBJ can fly from Paris to Los Angeles – or even farther – nonstop.

Boeing 737-700 Engine
The 737-700 model is powered by new CFM56-7B engines produced by CFM, a joint venture of General Electric Co. of the U.S. and Snecma of France. The engines meet strict international noise restrictions.
The CFM56-7 combines the core of the CFM56-5 with the CFM56-3’s low pressure compressor and a 1.55m (61in) fan.
Like all Next-Generation 737 models, the 737-700C is also powered by CFM56-7 engines.
The high-performance derivative equipped with an option for up to nine auxiliary fuel tanks, providing it a maximum fuel capacity of 10,707 gallons (40,530 liters) and a maximum range of 5,630 nautical miles (10,425 km).
The new engines and wings allow the 737 to cruise at Mach 0.78 to Mach 0.80, while the larger wing allows greater fuel tankage and transcontinental USA range.
The 737-700ER has the longest range capability of any 737 category and permits airlines to profitably serve new nonstop, point-to-point routes. The 737-700ER aircraft has the same performance characteristic of the other models of the Next-Generation 737 family (737-600, 737-700, 737-800 and 737-900ER) such as lower maintenance costs, reliability, lower operating costs and state-of-the-art flight deck systems.
Boeing 737-700 Avionics
Having six-screen LCD glass cockpit with modern avionics, the 737-700 maintains crew commonality with previous generation 737.
In the flight deck, large liquid-crystal displays are complemented by flight-management software and industry-leading display that decrease flight delays and enhances safety and flight-crew efficiency: Vertical Situation Display, which give us the current and predicted flight path of the aircraft and shows potential conflicts with terrain, and the Head-Up Display (HUD), which provides “eye-level” flight and useful knowledge.
The Boeing 737-700 aircraft has the identical fuselage as the 737-300 and fixed with new wing, tail sections and stabilizer.
Advanced-technology Blended Winglets are presented on the 737-700, 737-700ER, 737-800, 737-900ER and Boeing Business Jet (based on the 737-700 and 737-800). Performance advantages comprise : fuel burn reductions of up to 3.5 percent and increased range.
Other characteristics - contain a 777 style EFIS flightdeck with six flat panel LCDs which can be programmed to show information as on the 777 or as on the 737-300/400/500 series, permiting a common pilot type rating for the two 737 families.
The improved Next Generation Boeing 737 family (originally covered by the 737X designation) was launched in November 1993.
For the digital cabin pressure control system on the 737 Classics, the step to manually open the valve (step 3C) is removed, since the valve is opened using the AUTO mode in the steps that follow.
For the procedures applicable to the -600/ -700/-800/-900, steps 5 and 6 to open the valve are removed since the valve is normally open at the beginning of the procedure. Also added step to verify that valve is open at the beginning of the procedure and standardized wording of steps.
Boeing 737-700 Safety
Here a Boeing 737-700 recently completed successful technical demonstration test flights that proved its performance capabilities and in high-elevation, high-terrain environments.
The versatility of the aircraft allows owners to make a unique environment tailored to their specific requirements and seating necessities, whether it’s for eight or 100 passengers; for private use, corporate, charter or government transport.
In February 2003, a Boeing 737-700 successfully completed 11 test flights at Paro International Airport. The series included two technical demonstration flights and eight customer relations flights with Druk Air Royal Bhutan Airlines, the national airline of Bhutan.
The rigorous test flights demonstrated that the 737-700 is able of meeting all performance and procedural necessities for safe operations at Paro and other airports in high-elevation, high-terrain environments.
The 737-700 performed flight maneuvers as expected and met or exceeded performance expectations for simulated one-engine-inoperative maneuvers, which were accomplished by decreasing thrust on one engine to idle power.
The 737-700 demonstrated engine-out takeoff procedures engine-out missed approach and go-around procedures, and Druk Air procedures for landing on both directions of the runway at Paro.
