Boeing 737-700ER

The Boeing 737-700ER is a long-haul passenger airliner, a modification of BBJ (aircraft aimed at serving wealthy citizens), designed for ordinary passengers.

The Boeing Company began implementing a program to create a Boeing 737-700ER modification with an increased flight range on January 31, 2006, after receiving an order for the conversion of two Boeing 737 aircraft from ANA (All Nippon Airways). Commissioning was scheduled for early 2007. The Boeing 737-700ER modification has the longest flight range among aircraft belonging to the Boeing 737 family. This airliner provided airlines with the ability to efficiently perform non-stop flights and serve longer routes. ANA Airlines exercised its right to replace Boeing 737-700s with a Boeing 737-700ER. Two 737-700ER aircraft are part of an order for 45 Boeing 737-700s, which was placed by this airline on June 23, 2003.

The Boeing 737-700ER is another modification of the Boeing 737 that opens up new perspectives for customers. He is a great example of addressing the new challenges facing companies in the aviation industry. The first Boeing 737-700ER was delivered to ANA in early 2007. This aircraft opened up new opportunities for the airline to expand its route network, as it was able to operate flights on routes that served only wide-body aircraft, and also made it possible to increase passenger comfort.

The creators of the Boeing 737-700ER modification relied on the experience gained in the design of the Boeing Business Jet. It is similar in size to its prototype, but additional fuel tanks are installed on it and the maximum take-off weight is increased. The aircraft is operated by airlines on long-haul routes. On the fuselage of the standard Boeing 737-700, a wing and landing gear from a larger modification of the Boeing 737-800 are installed. The flight range of the Boeing 737-700ER increased by 3900 km compared to operating Boeing 737-700 aircraft.

At the choice of airlines, a beveled wingtip and up to nine additional fuel tanks can be installed on a Boeing 737-700ER, and then the aircraft will be able to carry out flights on routes up to 10,000 km long. The new Boeing 737 will have the same high operational reliability as other Boeing 737s. The Boeing 737-700ER is also characterized by low operating and maintenance costs. The appearance of this airliner made it possible for airlines to fight for new markets, for example, using aircraft equipped with first-class cabins for long-haul flights.

The Boeing 737-700ER is almost ideal for airlines with low ticket prices that seek to open long-haul routes. Modification of the Boeing 737 Next-Generation was created ten years later than its main competitor. Aircraft of this modification has a larger ceiling, greater speed, and range compared to similar aircraft of a competing company.

By that time, 95 airlines had placed orders for more than 2,960 Boeing 737 Next-Generation aircraft. The volume of orders for the Boeing 737 to be completed by Boeing is more than 1,130 airliners. Their cost at catalog prices is approximately $ 69 billion. The 737NG series is noticeably different from the first aircraft of the 737 families.

The Boeing 737NG is a completely new series that has little in common, besides the fuselage design, with the original Boeing 737 aircraft. The biggest changes are new wings, new avionics, and improved engines. On NG, the so-called “glass cockpit” equipped with displays on cathode ray tubes (on a Boeing 737-900 – on liquid crystals) instead of the usual “alarms” – analog devices, and digital systems. Most of these systems were borrowed from the Boeing 777, as well as the design of the cabin and passenger compartment. The total number of aircraft parts was reduced by a third, which reduced its weight and improved handling. Additional conversions also include vertical wingtips, significantly reducing fuel consumption and improving take-off and landing performance.

The vast majority of the 737 families are commercial aircraft of the Classic and Next Generation generation, including 737 Next Generation (NG) NG: 737-600, Boeing 737-700, 737-700ER, Boeing 737-800, 737-900, 737-900ER (manufactured since 1997), developed in the mid-1990s. Since then, these aircraft are the fastest-selling 737s in history, and on April 20, 2006, sales surpassed the Classic 737, with an order for 79 aircraft from Southwest Airlines.
