Boeing 737 passengers. The layout of the best seats in the cabin. Design Features and Benefits

Many people often have to use airplanes when traveling on vacation or business trip. And what does everyone think about when they are going to fly somewhere? Of course, about a calm, safe and comfortable flight.

To do this, before taking a plane ticket, you need to make sure it is reliable and find out how the seats are located in the cabin. The main aircraft manufacturer is Boeing, which produces a wide range of aircraft. different types and configurations.

On this moment the world's most widespread narrow-body jet passenger aircraft aircraft are Boeing 737.

Since the Boeing 737-800 medium-haul aircraft has received the greatest popularity among the world's airlines, this article will be devoted to its characteristics and the location of seats in it.

This is the third group of aircraft from the Boeing 737 - Next Generation group, created in the company's competition with manufacturer Airbus A320. The aircraft differs from its predecessors in that a new generation of aircraft is being produced with digital cockpits, new wings extended by 5.5 m, tails and an improved engine.

The Boeing model 737-800 aircraft was developed to replace the Boeing model 737-400, began to be used in 1998-1999 and flies today. Produce two modifications aircraft of this model: the passenger flight version of the Boeing model BJ2 and the modification used for military purposes - the Boeing 737 type 800ERX.

The main characteristics of the Boeing 737-800

We list the main characteristics of the Boeing type 737-800 aircraft:

• his dimensions are 39.49 m (length) and 12.51 m (height);
• the span of each wing is 34.31 m and their area is 125 m.
• fuel tanks are quite capacious (volume -26,020 l), allowing the aircraft to fly over distances up to 5400 km;
• the aircraft allows you to reach speeds of up to 851 km / h, while the length of the run is 1,630 m;
• the aircraft is controlled by two pilots (there are only 2 seats for the crew).
• Salon can not be called so spacious. Its width is only - 3.54 m. This aircraft has seats for the first (189) and second (16) classes. By the way, the developer provides for the possibility of changing the location and changing the number of seats depending on the requirements of the customer. For example, in most airlines in the first (tourist) class there are 184 seats, and in the second - 12 (16) seats for business class and 144 seats (or 148) for economy class.

The number and location of seats in the Boeing 737-800

This plan shows a model of a Boeing 737-800 with 184 first class seats (no second class). In the diagram, red and yellow colors indicate following places with a low degree of comfort:

• first-row seats located near the galley (there is less legroom and a folding table is attached to the armrest);
• in rows 10 and 11 (there is no porthole);
• 13 and 14 rows (there, due to the location near the emergency exit, the chair cannot be folded back and there is a lower temperature near these seats).

The greatest discomfort is felt by passengers sitting in the seats of the last row. There, the seats do not recline and are located near the toilet. Places of increased comfort are marked in green (16th row). Due to the lack of front-facing chairs, you can freely stand up and stretch your legs.

This plan shows the cabin of a Boeing 737-800 with 16 seats for business class passengers and 144 for economy class passengers. In economy class, increased comfort can be experienced in the 15th row due to the lack of front seats.

Low comfort in the seats of the 7th row (the front partition between the classes is located there), in the 10-11th rows (there is no porthole), in the 13-16th rows (there are emergency exits and the wing closes the view from the window) and in the last row (there is toilet).

Boeing 737-800 security

Sometimes, unfortunately, accidents in aviation happen, but the frequency of their occurrence is constantly decreasing, thanks to the constant work of the designers of the Boeing concern to improve the level of safety in aircraft structures.

So, in the aircraft of this company, the probability of losses is very low - several times lower than the general world indicator, for this reason Boeing aircraft can rightly be called safe. Use Boeing aircraft and all your fears about accidents and discomfort will definitely not be confirmed.

Surely, many passengers asked before the flight the question of how much the plane weighs, on which they will travel. The imposing appearance of the iron bird makes one think that the weight of an aircraft hovering in the air actually reaches hundreds of tons.

Of course, any aircraft is designed for a certain number of passengers, baggage and fuel, so the weight of individual aircraft models can vary significantly.

Each model has an allowable takeoff maximum, which consists of the own weight of the aircraft, the weight of fuel required for the flight, the weight of passengers with luggage and hand luggage. Considering the takeoff maximum, airlines set a limit on the number of passengers and luggage they can carry.

The restrictions are caused by security considerations - after all, even a few extra pounds for each passenger can create an emergency in flight. In larger aircraft models, the limit hand luggage and baggage, respectively, higher. Therefore, it would be useful to find out how much the planes of the most popular models in commercial aviation weigh.

Boeing 747 aircraft weight

The Boeing 747 passenger aircraft has rightfully topped the rating of the largest and heaviest liners for transcontinental flights for thirty years. Its first flight took place back in 1969, and since then it has been operated by all major world airlines. The crew of the aircraft consists of two people.

It can fly without refueling up to 15,000 km at top speed 1102 km / h with six hundred passengers on board. There is a kind of record in the history of the Boeing 747: during the hostilities in Ethiopia in 1991 (Operation Solomon), 1112 Ethiopian Jews were taken aboard the liner to Israel and saved.

Involuntarily, the question arises - how much does the plane itself weigh, and what is its maximum takeoff weight. With a length of 76.4 meters and a wingspan of 68.5 m, an equipped empty Boeing 747 weighs, taking into account the amount of fuel, within 162-215 tons. The maximum allowable takeoff weight of modifications is given in the table:

This model of airliners "distinguished" also by the fact that on board the Boeing 747, the Space Shuttle ships were transported to the cosmodrome.

How much does a Boeing 737 weigh?

One of the most reliable passenger aircraft, the Boeing 737 has excellent technical characteristics. The model was developed and put into operation in 1964. Since then, the aircraft has occupied the first positions in the ranking of the safest and best-selling passenger liners. The weight of an empty equipped Boeing 737 is in the range of 27-45 tons. You can find out the maximum take-off weight of its modifications from the table:

How much does an Airbus plane weigh?

Despite the huge popularity of Boeing for passenger traffic to near and long distance, today they are not the largest commercial airliners. Since 2007, the first position in the ranking of the largest transcontinental aircraft in operation has been taken by the double-decker Airbus A380 model.

This giant was developed in 2005 by the European airline Airbus S.A.S. To reduce the weight of the aircraft, the inventors used in the design composite materials. The aircraft is capable of speeds up to 1020 km/h in flight and overcoming 15200 km without landing.

Today it is the largest airliner in the world, with a wingspan of about 80 meters, a length of over 70 meters, and the allowable number of passengers on board in a three-class version is 555, in a single-class cabin - 850 people. Despite its huge size, the crew of the liner consists of two pilots.

The Airbus A380 is a worthy competitor to the Boeing 747, which has already begun to become obsolete. According to the size, the net mass of the airliner ready for flight, depending on the modification, is:

It is not surprising that with such a "net weight" the maximum takeoff weight of these aircraft is 560-590 tons.

Aircraft weight Tu 154

The most exploited on the territory of the USSR and on post-Soviet space is a jet passenger aircraft Tu - 154, named after its designer - Tupolev A.N. The production of Tupolevs was carried out from 1968 to 2013, during which time 998 aircraft were put into operation.

The main modifications of the Tu-154 are Tu-154B, Tu-154M. Tu-154B production started in 1975. During this time, 378 Tu-154B-1, Tu-154B-2 aircraft were produced. The length of the Tu-154 B-2 is 47.9 m, the wingspan is 37.55 m. Net weight passenger aircraft Tu-154 B-2 - 92 tons, and the maximum takeoff weight– 98t.

The crew of the aircraft consists of 5 people, the number of passengers is up to 180.

The Tu 154M aircraft began its flights in 1982. Until the end of serial production in 2013, more than 400 aircraft of this modification were put into operation, which is still in operation today. civil aviation.

With an aircraft length of 48 m, the wingspan is 37.55 m. An empty Tu-154M weighs 53 tons, and its maximum takeoff weight is 102 tons.

Tu-154 is piloted by a crew of 3 people, maximum amount passengers on board - up to 175 people. At the same time, the flight range of the Tu 154 B-2 is up to 2,780 km at a top speed of 950 km/h, while the Tu-154M has a higher flight range of up to 3,900 km at a maximum speed of 935 km/h.

How much does the largest plane in the world weigh?

If among passenger airliners By right, the largest aircraft in the world is the Airbus 380, then the championship among all types of aircraft from the beginning of their operation to the present day belongs to the Ukrainian giant AN-225 "Mriya" (Dream). This is a transport aircraft developed by the designers of OKB im. Antonova (Ukraine).

If we talk about the technical characteristics of the aircraft, it should be said that the machine has a length of 84 m, and its wingspan is 88.4 m. Its movement is provided by six turbojet engines, which makes it possible to fly with a range of 15,000 km at a cruising speed of 850 km/h .

An-225 was designed to provide transport system during the construction of the reusable spacecraft "Buran". The task of Mriya included the delivery of the spacecraft and elements of the launch vehicle from the construction site to the cosmodrome. In addition, it was planned that Buran could be delivered from an alternate airfield in the event of an emergency landing.

What is the weight of this truly unique machine? Takeoff maximum weight"Mriya" is 600 tons, and the weight of the transported cargo is 250 tons. At maximum load, the aircraft is capable of covering a distance of up to 4500 km.

At the same time, it is possible to transport monocargoes with non-standard dimensions and weight up to 200 tons on the aircraft fuselage (outside).

Mriya made its first flight in December 1988. Unfortunately, at present, only one aircraft is in working order in Ukraine, which is operated by Antonov Airlines for commercial purposes for international transportation.

It is difficult to imagine modern civil aviation without Boeing family aircraft. These machines fly on all medium and long-range passenger routes, connecting cities and entire countries with each other. Quantity aircraft wearing the logo on board Boeing, impressive. To date, this American aerospace corporation has managed to manufacture and deliver to customers more passenger airliners than others. More than 8,000 units of Boeing-737 aircraft alone were produced. This figure is an absolute record for today.

New Boeing - a problem with two unknowns

The market for passenger aircraft of small capacity, capable of carrying out domestic passenger air transportation, was a huge field for activity in the early 60s. The British, with their machines from the aircraft manufacturing firms BAC (British Aircraft Corporation) and the aircraft manufacturing corporation McDonnell Douglas, could become monopolists in this segment of passenger ships. Unlike Boeing, passenger liners BAC 1-11 and DC-9 were already ready and passed the stages of certification. In the future, it was planned that these two aircraft could become the basis of the aircraft fleet of the majority European airlines. The Boeing Company, carried away by the construction of long-haul aircraft, could remain on the sidelines in the division of such a huge market. To correct similar situation, was solved by creating a new jet passenger aircraft based on the Boeing-727 aircraft.

These are Boeing-737 300 aircraft today, Boeing liners-737 400 and Boeing-737 500 series aircraft are the main vehicle most of the world's airlines, and then, 50 years ago, the situation for Boeing began with a modest aircraft designed for 100 passenger seats.

The new airliner was supposed to squeeze British cars and aircraft from MCDonnelL Douglas, Boeing's age-old competitor, from the short-haul air transportation market. Work on the creation of a new machine began in 1964. In order to speed up the process of creating a new aircraft, the existing technological reserve used in the construction of the 707 and 727 series liners was used. The situation was similar in the case of the Boeing 737. The base machine has become a technological platform for the production of the largest series of passenger aircraft in the history of civil aviation. The plane, created 50 years ago, continues to fly today. The Boeing-737 800 modification remains today the most massive passenger aircraft on medium-haul airlines, sharing the palm with its European counterpart, the Airbus A320.

This was subsequently clearly manifested in the external similarity of the new aircraft with its predecessors. However, the planes also had significant differences. The new Boeing had a new wing design, which allowed the aircraft to be operated on shortened runways. The cabin of the Boeing-737 aircraft has also changed, which has become a two-seater. From that moment on, almost all subsequent Boeings had a crew of two.

At the same time, work was underway to create an aircraft for the European market and for the needs of American airlines serving the domestic market. Accordingly, both machines differed in capacity and some flight performance. The first-born received the Boeing-737 100 index and was built under the order of European airlines. The Boeing-737 200 was supposed to fly 3500 km, carrying up to 130 passengers on board.

One of the main conditions for Boeing's customers was precisely the ability of the new aircraft to be operated at provincial airfields and airports in the Old World, where the length of the runway is limited (up to 2000 m).

Subsequently, it turned out that with the new wing, the aircraft turned out to be more economical than planned. Significantly increased cruising speed machines and practical ceiling.

The internal structure has also changed. The Boeing-737 had an interesting cabin layout. Unlike traditional way placement of seats 4-5 in one row, it was decided to install passenger seats of 6 pcs. in one row. As a result, the salon has become coach. By the spring of 1965, the basic concept of the car was formed and ready. Instead of the previously announced 60 seats, the number of seats on the new aircraft has increased to 100. It should be noted that the increase in the capacity of the aircraft occurred under the influence of customers. The largest German airline Lufthansa placed an order for the first 22 aircraft at the stage of aircraft development. For the American market, another version of the Boeing-737 200 was created. This aircraft had 1000 km more flight range and accommodated 30 more passengers. The main customer was the American airline United Airlines. For its needs, the company placed an order for the construction of 40 machines of this type.

Serial production began in February 1965 at the Boeing Field plant in Seattle. Since 1967, the fuselages of all subsequent modifications of the Boeing were assembled at a plant in the city of Wichita. In 1970, all production was transferred to the plant in Renton. For three years, from 1967 to 1970, 271 first-generation machines were assembled at all assembly sites. Of this number, only 40 units account for the very first version of the aircraft. Subsequently, it was decided to switch to a more economical and cost-effective Boeing-737 200 liner. In total, from 1967 to 1988, 1114 aircraft of this type were produced in various modifications. Aircraft were supplied to airlines all over the world, flying in Europe and Asia, serving passenger air transportation in Latin America and Africa.

It will take almost 10 years before the next modification, the second-generation Boeing-737 300 aircraft, enters the line. Later, next-generation aircraft, 400 series liners, Boeing-737 500, 600, 700 aircraft and Boeing cars, will begin to roll off the assembly lines of the Boeing factory. -737 800 series created directly for a specific customer. The huge reserve of strength in the design of the aircraft allowed manufacturers to quickly and easily improve the aircraft in the future, responding to changing market conditions.

The subsequent fate of the most numerous passenger aircraft

At the end of the 70s, it became clear that the Boeing-737 200 aircraft began to lose to their main competitor - another American DC-9 aircraft in terms of profitability. In 1979, work began on improving the basic model. The main task was to increase the passenger capacity of the aircraft. By the new year 1980, a new Boeing-737 300 was ready, capable of carrying up to 150 passengers. The avionics of the Boeing 757 and 767, a new generation of wide-body airliners, was used in this aircraft.

IN new car used an old airframe from the "200" version. The control system and the internal layout of the aircraft remained unchanged. However, the fuselage was lengthened by 3 meters. Unlike the previous machine, which used analog avionics, the Boeing-737 300 already had more advanced digital instruments and control and monitoring devices. The car was equipped with new engines, increased the comfort of the cabin. On your first flight new Boeing went in the winter of 1984. The novelty was capable of flying at a distance of up to 5000 km. The conditions for passengers on board have significantly improved, the aircraft control system for two crew members has been simplified. The next aircraft, the Boeing-737 400, was built in a similar way, which began to be produced in 1988. The reason for creating another modification of the aircraft was a request for charter flights. Many private airlines in the mid-80s are switching to serving tour operators, who often have to use charter flights.

In this version, American aircraft designers again lengthened the fuselage, which now had a length of 36.4 meters. Due to this, the number of passengers on board again increased by 19 people. The version of the Boeing-737 400 was created for private airlines operating charter flights. The air conditioning system on the plane has changed, additional emergency doors have appeared - two on each side. The fuselage of the car received a support heel in the aft part, protecting tail section during takeoff from touching the concrete runway.

All subsequent versions were produced with a difference of 5-8 years, confirming the idea that the first machine-737 had a huge technological and design potential.

In 1990, the old Boeing 200 series was replaced by the new Boeing-737 500. Then came the turn of cars with indices 600 and 700. The number of cars produced was limited by the size of the order. These liners were created for the needs of low-cost air carriers operating on international and domestic airlines in Europe and North America.

Boeing aircraft today

The logical conclusion of the story with the Boeing-737 aircraft was the appearance on the air routes of a full-fledged airbus - the Boeing-737 800 aircraft. The car was created as an alternative to the European car, the Airbus A320. This modification had a fuselage length of almost 40 meters. The number of passengers increased to 190 people. The main customer of the new aircraft was the transnational corporation Hapag, headquartered in German Hamburg. The appearance of the Boeing-737 800 was a commercial deal designed to shake the position of the European aircraft corporation Airbus S.A.S, whose aircraft became last years serious competitors to American cars.

Boeing 737- is one of the most famous and operated model ranges of narrow-body aircraft. Boeing has been on the market since 1967 and to this day holds a leading position: in 2014, the company announced that it had launched its 8,000th anniversary airliner. The largest operator of Boeings of different generations is an American airline. Southwest Airlines. In her aircraft fleet is in total Boeing 684.

Boeing 737-700 from Southwest Airlines' Next Generation series

Boeing 737 is not an aircraft model, but the name of a whole "family", which includes 3 + 1 series:

1. original;
2. classic;
3. NG (Next Generation);

This group is the smallest, it includes only 2 modifications: 737-100 And 737-200 . These aircraft were produced from 1967 to 1988. To date, the first model is not operated due to fuel inefficiency, expensive service, and its technical characteristics are very outdated. The second modification is quite rare for the same reasons. The specific fuel consumption of the Boeing 737-200 is about 33 g/pass-km. For example, it is worth noting that the next model required fuel of about 26 g / pass-km.

According to Boeing, not a single 737-100 remained airworthy after 2007, so this model can only be seen in aviation museums or in photographs. The 737-200 modification is mainly found either with low-cost carriers or with airlines owned by developing countries.

Boeing 737-100 aircraft

Classic

Over time (by 1979), the need to design new aircraft became extremely relevant, since in addition to high fuel costs, as well as expensive and time-consuming maintenance, the "original" aircraft had another problem - an increased noise level on board. Already in 1980 based on Model 737-200 Advanced engineers presented to the world a modern liner for that time with 150 passenger seats - 737-300 . He received both new engines and an improved interior. The main differences of this aircraft, due to which it could no longer be classified as "original", were changes in aerodynamics and the appearance of a forkil. The length of the aircraft Boening 737-300 has increased by 3 meters compared to its predecessor and amounted to 33.18 meters. Flight range - 4,400 km.

Boeing 737-400 was developed primarily on the basis of numerous requests from charter carriers in order to increase the cabin, which required a complete redesign of the air conditioning system.

Airplane Boeing 737-400 it is easy to recognize two by the missing portholes on each side, additional escape hatches leading to the wings, and the so-called tail heel, which protects the structure from destruction as a result of touching the runway.

The latter feature was later carried over to other stretch liners (-800 and -900). The length of the fuselage of the 400th model is about 36 meters, and the cabin capacity is 168 people. The maximum range of flights is 5,000 km.

Boeing 737-400. Missing portholes and 2 emergency exits are clearly visible

Boeing 737-500- the smallest representative of the classic series (2 meters smaller than its predecessor), but at the same time it can cover distances up to 5,200 km and is still operated by many airlines. Serial production ceased in 1999, as the company introduced a more modern alternative - the Boeing 737-600, which already belongs to the "new generation".

next generation

Aircraft of the new series ( -600 to -900) received improved and economical engines, a wing with the possibility of installing aerodynamic wingtips, as well as an improved interior. In addition, the Boening NG liners began to cover longer distances: from 5,648 km to 10,502 km (modification 737-700ER), depending on the model. The first liner from this series was released in 1997, and production continues to this day. The takeoff speed of a Boeing 737 aircraft is on average 220 km/h, but much depends on the aircraft model and external conditions.

MAX

The release of this series is just planned. The Boeing 737 MAX has already been tested. Boening claims that the new aircraft will use on average 16% less fuel than the Airbus A320. The new series will not include an aircraft based on the 737-600 modification. So far, the company has already received more than 2,000 orders from 47 airlines. The launch of the first Boeing 737 MAX aircraft is scheduled for 2017.

New Boeing 737 MAX

Main technical characteristics of Boening 737

Passenger capacity Boeing 737 is different. The smallest number of passenger seats among the Boeing aircraft that are used today has one of the modifications of the 737-500 model (102 seats). The largest salon was received by the model 737-900ER (215 seats). Separately, it is worth mentioning the "pioneer" variation - 737-100. In the cabin of this salon, 99 seats were installed.

If you are interested, how many engines in the Boeing 737, there are 2 of them on all models. Aircraft from the Original series were equipped with Pratt & Whitney JT8D-1 engines, but later they were replaced by JT8D-7 with the same thrust - 63 kN. "Classic" liners operate on other devices - CFM56-3 with a thrust of 82-105 kN. The New Generation series received more modern engines - CFM56-7B with thrust up to 121 kN. In addition to the modified device, they make it possible to control the liner using the Fly-by-wire electrical system.

Three fuel tanks are located in the central part and wings of the liners. First of all, fuel is consumed from the first. The total capacity of the tanks of "original" aircraft is from 12 to 15.5 thousand kg, "classic" - 16 thousand kg, liners of the "new generation" - 20.8 thousand kg. Boeing's plans for the MAX series include the installation of up to 9 additional fuel tanks, which will increase the flight range by several times.

Can't answer unambiguously what is the price Boeing 737 aircraft, since a lot depends on technical condition liner, model, modification and other factors. Estimated price various aircraft can be seen in the table.

In contact with

Despite the fact that the American corporation produced the first Boeing 737 half a century ago, the aircraft is still in demand among air carriers. The liner continues to be manufactured to this day, with more than 9,500 units already produced. Aircraft of the 737th series have a narrow fuselage and are designed for flights on medium-haul routes.

Boeing 737 modifications

Behind long history liner developed and produced several modifications of the aircraft belonging to four generations.

Original

The first-generation Boeing 737 liners did not gain much commercial success, as they consumed a lot of fuel, were noisy and expensive to maintain. The last 737-100 aircraft has been out of service since 2007, and the 737-200 is still used by air carriers in Africa and some other countries.

On the basis of the Boeing 737-200, cargo and passenger-and-freight variants were created, and the 737-200 Executive Jet was produced for private owners.

Interesting! Prior to the release of the Boeing 737, a passenger aircraft was piloted by 3 people, including a flight engineer. Here, for the first time, a cockpit with two pilots was used, which became a revolutionary decision and was taken as the basis in all subsequent models of passenger liners.

Classic

Despite all the improvements of the Original generation aircraft, they began to lose significantly to their competitors. The new model was developed with significant changes. The aircraft received new engines, the fuselage became longer, and the number of passengers carried increased. The aerodynamics have changed, the liner was equipped with new digital avionics (on-board electronic systems).

The model 737-400, due to the enlarged cabin, changed the internal air conditioning system and added a second pair of emergency exits in the wing area.

Version 737-500 has a shortened fuselage, less capacity, but greater range.

new generation

The new generation Boeing 737 has been redesigned even more radically. The wingspan not only grew, but their geometry changed. Amendments have been made to the tail unit. The passenger cabins of New Generation aircraft and Boeing 757, 767 have much in common, since the design of the interior space of the Boeing 737 was based on design developments for these liners.

Each successive version of the New Generation has great length with a virtually unchanged fuselage diameter, and the latest 737-900ER engines, thanks to an improved wing design, consume less fuel at cruising speed.

Interesting! Based on the Boeing 737-700, 737-800 and 737-900, BBJ, BBJ2 BBJ3 (Boeing Business Jet) are produced, which are the most popular in the world among private customers. On board, at the request of the customer, a bedroom, a shower room (bath), a hall for business meetings, etc., are arranged).

The layout of the passenger compartment

The device of the passenger compartment depends on its dimensions, which can differ significantly in various modifications. In addition, different layout options are ordered by airlines. The most common cabin option is a two-class one:

• Business Class;
• Economy class.

There are options with one economy class cabin. The total capacity ranges from 103 passengers in the 737-100 version to 220 people in the 737 MAX-9.

Business Class

The business class has soft comfortable seats with a large folding angle. The location of seats in most layout options is according to the 2-2 scheme. In total, there are from 2 to 5 rows in the bow cabin. Most often - 4 rows.

In front of the aircraft, in front of the seats, there is a kitchen for clients of the elite cabin and toilets. Most quiet places are the seats of the 2nd and 3rd rows. Seats in the 1st and 4th row may not seem as comfortable due to the presence of nearby toilets, a kitchen, and in the case of the last row, a more crowded economy class. On some airlines, economy class is separated only by a curtain.

Economy class

In almost all economy class cabins, the seats are arranged according to the 3-3 pattern. Above are luggage racks. Toilets and a kitchen are located at the tail of the aircraft.

All airlines consider the seats of the first row, immediately behind the business class, to be the most comfortable in the Boeing 737. It provides more legroom. Often tickets for this row are more expensive or sold to holders of bonus cards.

Inside the cabin, in the middle part, there is one pair of emergency exits or two, depending on the version of the liner. Seats near emergency exits also have an increased distance between the seats, but passengers can be uncomfortable with the rigid fixation of the seatbacks and side bulges on the aircraft wall. But the seats right behind emergency exits recline fully and have extended space. Row numbering is specified by the carrier.

Important: The worst seats are in the last row of the aircraft. The proximity of the bathrooms and the kitchen creates fuss and noise, and the seat backs do not fold out or recline slightly.

Design Features and Benefits

Each aircraft component has its own characteristics and associated benefits:

1. The design of the liner is a monoplane with two engines placed on pylons and swept wings.
2. Tricycle chassis have a front swivel leg. The main support is not closed by the flaps after folding is completed. This can be seen from the visible wheels. This solution simplified the design and reduced the weight of the liner, but somewhat worsened the aerodynamics.
3. Since the engines are located low, it was necessary to slightly reduce their vertical dimensions. To do this, partially lower equipment for the engine was placed on the sides and the air intake was slightly extended horizontally. The engines received a flattened shape, especially noticeable in the latest versions.
4. Winglets (wingtips) on the wings underwent changes in the course of the evolution of the Boeing 737. At first, winglets of minimal size were made on the 737-200 modification. Subsequent generations of Classic and New Generation received large endings, which are now widespread. MAX generation aircraft use twin winglets.

• Messier-Bugatti equipped the liner in 2008 with carbon brakes. This allowed to reduce the weight by 320 kg and reduce fuel consumption by about half a percent.
• The cockpit with seats for two pilots originally had analog devices and instruments. Now all aircraft are equipped with digital control systems with liquid crystal displays. Previously, there were additional windows on top of the cockpit, which improved visibility when maneuvering and made it possible to navigate through the starry sky. Later they were removed due to the installation of modern orientation devices.
• The most serious changes were made to the internal structure of the cabin. For almost every generation of liners, it was redesigned taking into account the increase in comfort and the optimal location of passenger seats.

General advantages of the Boeing 737:

• ease of takeoff, climb, landing;
• high load capacity;
• reliability and long term operation;
• low maintenance costs;
• comfortable, well-equipped interior.

History of creation

When design work began on the creation of the new Boeing 737 in 1964, competitors from the British Aircraft Corporation and Douglas Aircraft were already well advanced in the production of their machines. They were ready to certify new short haul aircraft with small capacity. Boeing, in an effort to reduce the development time of the liner, took as a basis the technologies used in the production of aircraft of previous models - 707 and 727. But tests showed the unsuitability of the old wings for the new version. The newly created wing helped aircraft fly on higher altitude by reducing the consumption of aviation kerosene.

Seats in the Boeing 737-100 were located 6 in each row, providing more seating than competing aircraft manufacturers.

Interesting! Initially, 60 passenger seats were designed inside Boeing cabin 737-100, but subsequently settled on the 103-seat version at the insistence of the first customer, Lufthansa.

The development program was completed quickly and without the investment of large material resources. The assembly of the first aircraft was completed in the winter of 1967. In April, the liner took to the air for the first time, and in August it made a test flight of the Boeing 737-200.

The decision to operate the aircraft with a two-pilot crew caused serious discussions and resistance from trade unions, as the unit of a flight engineer or a third pilot was reduced. However, after trials and flight tests, the company proved the possibility of using two people for piloting, and airlines were even interested in this because of the cost savings.

At the end of 1967, both versions of the new Boeing were certified, and after 2 months Lufthansa began operating the liner.

In parallel, the aircraft was being finalized so that it could land on an unpaved runway. The tests were completed successfully and the Boeing 737 immediately became in demand for flights to distant towns in the northern United States and Canada. The extended model 737-200 was in great demand and was produced until 1988.

In the 80s of the last century, the Boeing 737 was redesigned, equipped with new engines and improved cabin. The first flight of the next generation Classic aircraft took place in 1984. Subsequently, two more were added to the 737-300 modification - 737-400, 737-500.

The European airliner A-320 in the 90s replaced the Boeing 737 in the segment of narrow-body aircraft, having technical superiority. And the airline corporation began to create a new series of modifications - New Generation. A total of 5 modifications were released - 737-600/700/800/900/900ER. Increased cruising speed large quantity fuel on board allowed long flights with reduced travel time. Thanks to this, the company opened up new markets.

Interesting! New Generation aircraft, except for the fuselage structure, are completely different from the first 737 liners. They have modified engines, completely new wings, and different avionics. Ideas for the interior of the cabin for passengers were even borrowed from the design of the Boeing 777.

The latest version of the NG Boeing 737-900 ER was released in 2007.

In January 2016, the Boeing 737 MAX 8 took off for its maiden flight. Aircraft of this series are designed to replace the New Generation liners.

Place of production

The geography of production of aircraft components is extensive. These are many European and Asian countries. Assembly work is carried out in the United States.

1. The fuselage for the Boeing 737 is assembled at the company's plant in Wichita, Kansas.
2. At the second stage, the aircraft body is transported to Renton (Washington State), where the final assembly is carried out. Final assembly takes approximately 2 weeks.

Operating companies

Boeing 737s are operated by world airlines in 115 countries. The largest number of liners of this type belongs to air carriers:

The aircraft is used both for transcontinental flights and for ultra-short flights. This is the main liner for flights to Alaska, to the northern regions of Canada, to the Pacific Islands.

Interesting! The shortest route operated by the Boeing 737 is 14 km. Transportation is carried out by the Japanese Japan TransOcean Air between the two islands in pacific ocean(Minami Daito - Kita Daito). Air Tanzania serves flights from Dar es Salaam to Zanzibar (65 km).

The cost of different models

The cost of the first generation models started at $ 49.5 million, but the price may vary depending on the configuration. Now only New Generation and MAX modifications are produced.

Development prospects

Prospects for the development of the 737 model are associated with a new generation of aircraft - MAX. Their production has already started.

Main changes and features:

1. New powerful engines have been installed. With increased power, they consume less fuel.
2. Changes have been made to the geometry of the airframe of the aircraft.
3. Chevron teeth are installed on the rear of the engines, which significantly reduce the noise of operation.
4. The cockpit will remain almost unchanged, but the interior of the passenger cabin will be produced with luggage racks and LED lighting, like the Dreamliner.

Recent improvements breathed new life into the Boeing 737 liners, which have already won wide popularity. The company's portfolio of orders is constantly replenished. Increasing comfort for passengers is added to reliability and safety.
