Boeing 737 400 interior diagram Yamal. Boeing flight characteristics

Transaero Airlines operates 5 Boeing 737-400 models. This aircraft is an extended version of the Boeing 737-300 (3 meters longer). Increasing the volume of the passenger compartment required engineers to redesign the air conditioning system. Another difference of this model is the additional two emergency exits on the wing of the aircraft. Operation of the model began in 1988 and until 2000, 486 aircraft were produced.

In total, the Boeing 737-400 Transaero has 140 seats, of which: 8 seats in business class (1-2 rows), 60 seats in economy class (10 - 20 rows) and 72 seats in tourist class (21-32 rows ). Let's take a closer look at the cabin layout of this aircraft and highlight both the best and worst seats for passengers.

With the development of the Internet, many services have made great strides forward. If earlier, when going somewhere, you had to get tickets in advance, now all this is done much easier. For example, you are flying on vacation. Using the Internet, you can book hotel rooms, provide a taxi from the airport to your place of residence, buy an air ticket, and all this without leaving your favorite chair.

Moreover, when ordering tickets, you can see in detail any information you need about the company and its fleet of vehicles. Take, for example, the layout of the cabin, the best seats, the location of the wings, kitchens and bathrooms - these questions can be found out without leaving the computer. Specialized sites can even book your chosen seat. At the same time, it is chosen by you, which is important, because on the plane there are both the best seats and standard ones.

Static design

While the model is on assembly lines, it can be improved, modified, and some blocks can be changed. This happens to all developers in the aviation industry. At the same time, developments are mainly carried out in terms of updating control systems, flight characteristics, tank volumes and other details that the average passenger will not see. This happened with the Americans, the developers of the Boeing 737 aircraft. The interior layout, regardless of model modifications, usually does not change its parameters. In terms of modifications, not a single company has moved, for example, the kitchen to the middle of the cabin. All cars have the same internal layout. With one caveat - unchanged within this model. And if you fly the 737 frequently, switching companies could mean you get better (or worse) service. The cabin of the Boeing 737 will not change - and after flying once, you will already know where exactly you were sitting, and whether it is worth choosing the same seat on your next flight.

Aircraft capacity

Speaking of passenger and cargo capacity, one cannot help but note the fact that this aircraft, which first took to the air in 1967, is still in demand among airlines. Over the 40 years of production, the aircraft has become more comfortable and safer. Components and parts were changed, navigation devices were added, and in some rare cases, passenger seats were added. At the same time, if you depict the number of places on a diagram, there will be peaks and drops, but the overall direction will increase. So, the 737-400 was one of the “giants” in the class. It carried 168 people and consumed resources, including refueling, much less than its class neighbors (737-300 and 737-500). The following modifications had a lower carrying capacity. This continued until the departure of 737-800, which took 189 people on board. Like all Boeings, with the exception of the 747 version, the Boeing 737 has a cabin layout that repeats the type of earlier versions - 6 seats in a row with one aisle between them (3+3), which made it possible not to change the width of the body. With the release of new versions, only the length of the aircraft changes.

737-400 and Transaero

Let's look at the interior diagram of a Boeing 737-400 from Transaero. Like many other American-made models, the aircraft has three classes: business, economy and tourist. Business class is represented by only 2 rows, but neither the first nor the second row can be called particularly comfortable. People sitting in the first row will have limited legroom due to the partition in front. The second row of seats, moreover, has another partition at the back, as a result of which the backrests do not recline. The partition is not that dense, so these passengers will hear the noise of their neighbors from the Economy.

Seats in the following salons are already three in a row. The entire economy class of the aircraft is designed so that rows of seats can move freely forward or backward, resulting in rows 14 and 16 having no windows. The next 17th (as well as 18th) row do not have the ability to recline the backrest due to the emergency exits located at the rear. At the same time, those sitting in the 18th row have a little more legroom. Those sitting near the window in the 19th row may not have one armrest - there is an emergency exit here, while those sitting in the same row in other seats do not have these problems.

The tourist class does not need any special introductions. Anyone who has flown in this class knows about the small legroom and other “conveniences” of flying in this cabin. We will only mention those who sit in the rear of the cabin. The entire last row is adjacent to the block of bathrooms, so it is quite noisy here, and the backs do not recline. The passenger sitting in the penultimate row at the aisle will feel the same way.

Best places

Above we looked at the standard layout of one of the most successful models of the Boeing 737 aircraft. The best seats on the plane are located in the 10th row, the first row of economy class. Passengers sitting at the aisle have the ability to recline their backrests, and at the same time, due to the narrower partitions than the aisle, the partitions between business and economy classes will have additional legroom. The same partition can cause trouble for neighbors in the row.

Airplane photo

And to complete the conversation, we will provide several photographs of the appearance of the Boeing 737 aircraft. Photo of the passenger version - model 737-400, Transaero airline, Russia.

For comparison - also the 400th, but a cargo version. If you look closely, you can see the outline of a pair of emergency exits above the wing (aircraft 737-400, Iceland.)

Their presence is explained by the fact that initially this aircraft was not planned as a cargo aircraft, but no one canceled the formula “demand creates supply,” and since all aircraft were produced for a specific order, this one flew out of American assembly shops in a cargo version.

Conclusion

A lot has already been said about the number “13”. It is all the more surprising that this topic also affected the developers of the Boeing 737 aircraft. The interior layout has row 10, row 12, 14... But 14 comes right after 12. The cabin has seats in the 32nd row, but they won’t sell you seats in the 13th row. This number is simply not available in the salon.

Boeing is a word strongly associated with a high-quality American-made passenger airliner. The popularity of the aircraft is so high that it is used by most airlines around the world. Boeings can be found at almost any airport. According to statistics, more than a thousand of these airliners are constantly in the air.

History of the 737 brand

The Boeing Company turned 100 years old in 2016. It can confidently be called the most famous corporation producing civil and military aircraft.

Production of the Boeing 737 began in the late 70s in America. The first test flight took place on April 9, 1967.

Over time, the 737 gave rise to a whole family of commercial aircraft. Today there are ten varieties of Boeing 737, capable of carrying from 85 to 215 passengers.

In the eighties, with the advent of new engines and digital avionics, a new group of Boeing 737s was born under the general name “Classic”. These include models: -300, -400 and -500.

More information about the history of the Boeing 737 aircraft can be found in the video:

Characteristics of the Boeing 737-400

The Boeing 737-400 is an improved version of the main aircraft of this series, the 737-300. The changes affected:

• the length of the aircraft, it has been increased by 3 meters;
• air conditioning systems;
• increasing the number of passenger seats;
• increasing the number of emergency hatches to 4 with exits to the wings.

When making changes, 2 windows were missing from both sides, making these aircraft easy to distinguish from others.

Look for cheap tickets for any type of transport without leaving your home:

Flight tests of the -400 were carried out in February 1988, and in October of the same year the first aircraft was purchased by Piedmont Airlines.

Designed for 150-160 passengers, this airliner is used for short and medium-range routes.

From the start of serial production in 1988 until its end in 2000, a total of 486 aircraft were produced.

Specifications

Boeing 737-400 interior diagram

There are 8 seats in the business class cabin (see diagram): A, B – left side and F, G – right side. Porthole seats - A and F.

Scheme for 140 places

Economy class can have 132 seats in a two-class cabin or 159/168 in an economy class cabin only.

The Boeing 737-400 economy cabin has more or less comfortable seats. The comfort of the flight depends on the choice of seat, especially if it lasts more than an hour. The greatest inconvenience during the flight is caused by:

• narrow space between seats;
• engine noise;
• disturbance by people passing along the corridor;
• inability to recline the back of the chair.

Therefore, comfortable places should eliminate all these inconveniences. On all planes these are the seats in the first row and near the emergency exits.

The best seats in the Boeing 737-400

After studying the interior layout, it is very easy to determine the best places. In Boeing 737-400 it is:

• 10 A, B, C, D, E, F
• 19 A, B, C, D, E, F

The 18th row is also not bad, there is increased space between the seats, but the backs of the seats are fixed for safety reasons.

There are no portholes in two rows; according to our scheme, these are rows 14 and 17. If this is important to you, please ask when checking in for your flight.

The last 9-10 rows in the rear of the plane are less comfortable. Sometimes airlines split economy class into two and sell those seats cheaper. But there are also advantages here:

If boarding has ended and there are still empty seats, you can change to a more comfortable seat.

Each airline's seat layout may vary slightly. Therefore, look for the cabin layout of the exact airline you will be traveling with, and remember the rules for choosing the best seats.

Compared to its analogue 737-300, the 400 model has become 3 meters longer. longer Therefore, the designers had to completely redesign the air conditioning and ventilation system. As a result, there are two missing windows on each side of the airliner. Instead of them there is a blank wall. And we will definitely touch on this when we select the best seats in the Transaero Airlines Boeing 737-400 scheme.

This diagram can be seen on the carrier’s official website.

Ask an airline employee for advice

If possible, carefully study the diagram of the airliner you will fly on.

Do not take seats where the seats do not recline or are limited in their ability to do so.

Do not take places near toilets, kitchens and other technical rooms at the very end.

1-2 r. business class was noted as not very comfortable, but you need to understand that “not very comfortable” for business class as a whole. Of course, they are much more convenient than both tourist and economy ones in this aircraft configuration. Let us explain this point of view. Places 1 r. They have a little free leg space, because the partition is located quite close. Places 2 p. They have a slight limitation in reclining and are closer to the noisier economy class, which causes inconvenience. These are, of course, trifles. However, business is business, we pay extra money for comfort.

10 rubles, seats F, E, B, A - due to the proximity of the partition, these are not very comfortable seats. It’s unpleasant to look at the wall the entire flight.

10 rubles, places D, C. Due to the fact that the partition does not span the entire width of the row, there is a small additional free space for the legs.

14-16 p., places F, A. On every plane, seats can move back/forward, the width of the aisle between the rows can change, and so on. At Transaero, the rows are arranged in such a way that there is a “window” next to almost every seat. But remember, this is where the section of blank wall is located. Such options are that the window is completely absent, inconveniently located, or still present. If this is important to you, please clarify this point when registering!

17 rub. - do not recline due to emergency exit. Places A and F may be “higher” by a few centimeters. thereby reducing the already narrow passage between the rows.

18 rub. - the backrests do not recline, but there is additional free space for the legs.

19 rubles, A,F - on the window side, the armrest does not move, as it is attached to the emergency door. It's also cooler here.

19 rub. E, D, C, B are good seats in economy class. There is legroom, the chair reclines without problems.

31 rub. C,D. Being close to the toilets means that passengers will constantly be walking back and forth and standing next to you, waiting for their turn.

32 rub. - the backrests do not recline, as they rest against the wall of the toilet. And other troubles, as they say All Inclusive: vanity, sounds of the tank, walking, and so on. The worst places on board.

A couple of general points about the seat arrangement in the Boeing 737-400 - their disadvantages and advantages.

1. The seats that are located next to the window have the advantage that you can look out of it during the flight (this, of course, depends on the flight time and weather). If you fly at night, this advantage does not count. Also, your neighbor will not bother you if he wants to get up. These places have one drawback - it is not very convenient to leave it yourself. Therefore, if you don’t need to go to the toilet often or you intend to sleep through the entire flight, choose seats by the window.

2. The seats located near the aisle have their own advantage - it is very easy to get up from if you need to go to the toilet. The disadvantages are that a neighbor may be disturbed if he needs to get up. Flight attendants with trolleys and passengers who walk through the cabin to the galley and toilets can also interfere. Therefore, if you are flying with a child and, most likely, you will have to go to the toilet often. Or you yourself need to go to the restroom more often, then choose from the edge of the seat.

Clear skies to you, as the pilots say, and a soft landing!

In the field of civil aviation, the Boeing 737 family of airliners has remained the most popular for many years. There are three generations of these aircraft - Classic, New Generation and MAX. "Boeing 737-400" is one of the modifications of the classic type, which is still used in passenger transportation to this day.

Development history

This type of aircraft was developed in 1985. Its main task was to become a transitional modification to the Boeing 737-200 type. The airliner competed with the Airbus 320 and MD-80.

The Boeing 737-400, compared to the previous 737-300 type, has a fuselage lengthened by 3.45 m, which allows it to carry up to 170 passengers. To prevent impacts on the runway, a bump stop is provided. The spars on the wing planes and the landing gear were also strengthened due to the increase in take-off weight.

Since the length of the fuselage was increased, this was followed by modifications to the cabin air conditioning system.

The 737-400 was first used by American regional carrier Piedmond, which at the time had 25 of the aircraft on order.

Nevertheless, there was also a need for air cargo transportation, which was the reason for the development of a new model. The cargo modification was named “Boeing 737-400F”. However, it was not widely used. While the combined modification of the Boeing 737-400 Combi, capable of carrying out passenger and cargo air transportation simultaneously, is still in use today.

This type was produced until 2000. Over these 12 years, 486 aircraft were created, most of them are used in air transportation to this day.

Flight performance parameters

The aircraft of this modification has the following parameters:

• Fuselage length/width/height - 36.5/3.76/4.11 m.
• Wingspan - 29 m.
• Total height - 11.1 m.
• The empty weight of the aircraft is 33.2 tons.
• Maximum take-off weight - 66.05 tons.
• Maximum landing weight - 56.1 tons.
• The maximum volume of transported cargo is 39 m3.
• The maximum flight range is 4204 km (approximately 1907 miles), at maximum load - no more than 3500 km.
• Engine volume - 23.8 dm 3.
• Engine type - CFMI.
• The aircraft speed at flight level is 800 km/h.
• The maximum flight altitude is 11.3 km.
• The maximum capacity of the cabin is up to 160 people.
• There are four emergency exits on the wing plane.

Boeing 737-400 cabin (Transaero): layout

Until October of this year, five 737-400s were in the fleet of one of the largest domestic air carriers, Transaero Airlines. They carried out both domestic and international regular and charter passenger flights.

The Transaero airliner is designed to carry 137 passengers.

The plane has only eight emergency exits, two of which are located in the nose and tail, and four on the plane of the wings. The cabin has lounges for business and economy class passengers.

If we consider the layout of the Boeing 737-400 model (Transaero), there are 42 rows only formally. The fact is that for business class passengers there are 8 seats at the beginning of the cabin, while the rows are numbered 5 and 6. And for economy class passengers there are 23 rows, numbered starting from 21 and ending with 42 .

The economy class passenger compartment is divided by a partition, which is located between the 29th and 30th rows.

The most comfortable seats are considered to be the first row of the economy cabin and the seats near the emergency exits. In the second cabin, row 30 is also the most convenient. The seats in the 41st and 42nd rows are considered uncomfortable places, since they are located near the toilets and have a non-reclining back.

Operators of the Boeing 737-400 model

As of 2010, 1,651 Boeing 737s of the classic type are in operation, including 419 units of the 737-400 modification. Asian and South American states, as well as the countries of the Persian and Gulf of Mexico, use the aircraft not only as passenger, but also military, and even government transport.

Domestic airlines also operate the Boeing 737-400 aircraft, including:

• "Transaero".
• "UTair".
• "Yamal".

The Boeing 737 aircraft, modification 737-400, is one of the most advanced aircraft of its time. It replaced the outdated type 737-100/200. Its design used more advanced electronic equipment and the latest jet engines. This aircraft has not been produced for almost 15 years. Despite this, many airlines and even government agencies use it for passenger air transportation. The 737-400 was replaced a few years later by the more advanced Boeing 737NG.
