Accommodation on a Boeing 737.

The Boeing 737-800 passenger liner, the brainchild of the Boeing Corporation, entered the Russian air transportation market in 2013, although it has been in operation with well-known global air carriers since 1998. The liner belongs to the third group of Boeings of the Next Generation series. Unlike the previous line, it has improvements.

In contact with

Here are some of them:

modern avionics;
new engines of CFM concern;
modernized tail unit;
elongated wings with vertical winglets - winglets.

Together, this significantly reduces fuel consumption and improves takeoff and landing maneuvers. This novelty is controlled by two pilots.

Flight performance of the Boeing 737-800

The model belongs to medium-range narrow-body aircraft. The key parameters of the Boeing 737-800 are shown in the photo on the right.

The flight range of 5700 km is the distance that the liner flies without refueling. Knowing this value and speed, one can easily calculate that a car with passengers can stay in the air for up to 7 hours. Of course, you want to spend them with relative comfort in good comfortable places that allow you to relax as much as possible.

The layout of the seats in the cabin is a variable value

The layout of the passenger compartment and its capacity are not constant values. They can vary within certain limits both for different companies and for different flight routes. The fact is that each air carrier, based on an analysis of the air transportation market and its needs, determines for itself how many seats are required on its aircraft and flights.

The maximum possible number of seats for installation in the Boeing 737-800 cabin is 189. But this does not mean that this number will be available. It all depends on the demand for the direction of this airliner, the category of flying passengers and the financial and technical capabilities of the airline. Therefore, somewhere 150 seats are enough, somewhere 189 are not enough, somewhere they think that there should be a class of increased comfort, and somewhere they ignore it.

The best and worst seats on an airplane, regardless of its model

A passenger can find out the layout of their aircraft by contacting a representative of the air carrier or by going to its website, which contains the layouts of the cabins of the entire fleet of a particular company. Nevertheless, there are general principles by which the best or worst seats in the cabin of a modern jet liner are determined, regardless of its model. Before giving a specific review of the Boeing 737-800 aircraft, we will impartially point them out:

Boeing 737-800 fleet at Aeroflot

All of the above criteria are also characteristic of the Boeing 737-800. But there are also individual characteristics. For example, let's take a complete set of aircraft of the airline as the largest air carrier in Russia, which has 27 units of this type of aircraft in its fleet. It is interesting that all of them were given personal names in honor of prominent people of Russia. There are Sergei Obraztsov, Aram Khachaturian, Alexander Solzhenitsyn, Leonid Utyosov, Vladimir Dal, Boris Kustodiev, Sergei Ozhegov, Ivan Krylov, Sergei Eisenstein, Nikolai Karamzin and others.

The layout of the seats on each side has its own

Aeroflot uses both two-class and one-class seating arrangements. Moreover, in order to find out which airliner has which configuration, you should not focus on the registration numbers of the aircraft. After all, as mentioned above, it can be changed by decision of the administration in accordance with the needs of the company.

So, in the current 2018, the Igor Stravinsky airliner with registration number VP-BMD has two classes of service, with a total of 158 seats. Over time, the aircraft can be reconstructed into three classes with a decrease in the number of seats, or, conversely, converted into one economy -class with increasing seats to the maximum. Alterations are possible both in the VIP version, and in the corporate version, and for the transportation of a military contingent.

To determine the type of layout in a particular Boeing 737-800 airliner, only a fresh scheme will help, which Aeroflot without fail offers all its passengers to review on the website.

Seats in business class

The location of the business class on the Boeing 737-800 of Aeroflot corresponds to five rows of luxury seats in the nose compartment of the aircraft. There are four seats in each row: two to the left of the aisle under the letters A and C and two to the right of it under the letters D and F.

The wide space between the rows allows you to comfortably position your legs without interfering with the passenger sitting in front. There are no folding built-in tables that would limit personal space. The chairs are mini-offices with individual lamps, armrests, sockets for equipment, touchscreen monitors, flight attendant call buttons, seat adjustment buttons that allow you to recline the back almost at an angle of 180 degrees. All this, together with improved service, costs the passenger 4-5 times more than the economy class.

Economy cabin features

Economy category seats are located from the 6th to the 28th row. There are six seats in each row, three on each side of the aisle. Their letter designation starts from the porthole porthole with the letter A and ends at the starboard porthole with the letter F.

A more private option is a chair by the window, a more open option is a chair by the aisle. The most dependent on its neighbors is the central seat in the row. After all, the passenger occupying it will not only share armrests with his fellow travelers during the flight, but also disturb the neighbor on the right - to look out the window, then the neighbor on the left - to go to the aisle for a warm-up.

The economy rows are not all the same in the Boeing 737-800. The layout of the salon and the best places for yourself in it must be studied in advance. Features of some rows are presented below:

6th. It is located right behind the partition separating economy from business class. The advantages of the row are the absence of front-seated passengers and the presence of wider legroom. However, most often this row is reserved for passengers with infants or young children, since there are brackets above it for attaching hanging cradles.
Seat, A in the 8th row, Seats, A and F in the 9th row. There are no portholes.
11th and 12th. In this part of the cabin, behind rows 11 or 12, there are four emergency hatches. Accordingly, their design does not provide for reclining the backs in full force.
13th. In front of it are emergency hatches with access to the wings. The row is separated from the previous one by a fairly wide space. The backs recline to the fullest. But as a rule, these places do not enter the free space. They are reserved for men with a strong physique, ready to use their strength to open hatches in an emergency.
11th-17th. These places are located in the wing area. Accordingly, the view from the windows from seats A and F will be limited.
18th-28th. This is the tail section of the aircraft. When flying through a zone of turbulence, the bumpiness in these places will be felt more strongly than in the bow or midsection. The same goes for engine noise. But with a low load on the aircraft, the passengers of these seats will be a clear winner. They will be able to freely accommodate alone on all three chairs in a row.
28th. Located in front of the partition that separates the cabin from the toilet. Accordingly, the folding mechanism of the chair will be absent. Flying 7 hours in a seated position with no way to relieve the pressure on your back is going to be tough.

The layout of the seats of the Boeing 737-800 in some airlines

To have greater clarity, let's compare the data on the location of seats for several air carriers.

A/c	Completion of classes	Best Places	Seats in the area of emergency hatches	tail places
Russia, a subsidiary of Aeroflot	Business: 4 rows. Economy: from 5 to 30.	The 16th row has an inter-seat zone SPACE +. Provided for extra. fee.	14 and 15 rows	23 to 30
S7	Business: 3 rows. Economy: from 4 to 29.	4 row. It is located right behind the barrier. Designed for owners of gold and platinum cards.	12 and 13 rows. In the 13th row, the chairs are assembled according to the 2 + 2 scheme.	20 to 29
UTair	Business: 1 row. Economy comfort: from 2 to 9. Economy: from 10 to 28.	12 row has an increased space between the rows of seats.	10 and 11 rows	20 to 28
Ryanair, Europe's largest low-cost carrier	Economy class only. Chairs are not equipped with a reclining mechanism.	Rows: 1, 2, 5, 15, 16, 17 - the most comfortable. Reservation for these places is provided for a fee. All other rows have a narrow step between them.	16 and 17 rows	25 to 33
Turkish Airlines	Business: 5 rows. Economy: from 6 to 28.	14 row has increased space between rows.	12 and 14 rows. Row No. 13 is missing in the numbering.	20 to 28

Thus, the layout of seats in a medium-haul Boeing 737-800 airliner can be of various modifications depending on the volume of passenger traffic of a particular airline on a particular route.

From the above examples, it can be seen that where an air carrier seeks to transport more people over short distances, it is abandoning the costly business class in favor of economical seats. And, on the contrary, on the long-distance routes that Aeroflot has, the availability of classes with comfortable accommodation is a priority and a direct economic dependence on the demand for routes.

The task of passengers is much easier - to choose exactly those places that will meet all their needs according to their interests. And this article is to help them.

Two concerns are considered the largest competitors in the civil aviation market: in Europe - Airbus, in the USA - Boeing. For the former, the A-320 is considered the flagship aircraft. The second responded with a no less successful machine, called the Boeing 737-800.

Boeing has a whole family of 737 aircraft that began their journey in 1967. Since then, the range has been constantly upgraded. 737-800 is a common model that has become a continuation of the successful Boeing 737-400.

History of creation

The 737 family has become popular in the civilian transportation segment. Moreover, the company has achieved such positions within the framework of the entire civil aviation of the world. Statistics say that 1,200 Boeing 737 aircraft are flying in the sky at any given time. And every five seconds, an airliner of this model is landing or taking off.

The countdown of the history of the family began with the models 737-100, and then - 737-200. But they turned out to be costly in terms of fuel consumption. The breakout oil crisis also influenced the change in the lineup.

They continued with the Boeing 737-300 models, and then the Boeing 737-400. The latter turned out to be successful and worked out the time measured for them. When the time came, the 737-800 was created on the basis of the 400th Boeing. Combining economy, technology and good passenger capacity, it quickly won the respect of the world's leading carriers.

To date, 737-800 is considered one of the most popular projects of the entire family.

The first delivery of liners was carried out in 1998. These aircraft are still flying and are used so widely that orders for them are booked for years to come.

The entire Boeing 737 family is currently represented by more than 10,000 models operating around the planet. And the demand for their production does not pass. The model range with the designation -800 is considered modern and technically advanced, and has not yet exhausted its resource to the proper extent.

In general, the 737 family is so large that it is even conventionally divided into generations:

original (which includes the first models with the designation Boeing-100 and Boeing-200);
classic (predominantly represented by Boeing-300, Boeing-400 and Boeing-500 models);
next generation (Boeing-600, Boeing-700, Boeing-800 and Boeing-900);
MAX (a new generation that is designed to replace the popular Boeing-800 and Boeing-900).

Boeing 737-900, which began to go on sale in 2001, differs from its predecessor (737-800) in a longer fuselage. After the presentation, this model received so many pre-orders in one day that it bypassed the entire family ordered for the whole year.

In general, each model of the 737 family has one characteristic feature. In addition to technical and structural changes, each new designation machine was longer than the previous one.

Fuselage, wing and cockpit structure, engines

The Boeing 737-800 differs little from the rest of the Next Generation aircraft in terms of aerodynamic design. But with the ancestors (737-100 and 737-200) there are already few common features.

The fuselage of the aircraft was lengthened by more than 3 meters (in comparison with the prototype - the 400th model), while significantly increasing the passenger capacity.

The new 737-800 models were created to replace the aging 737-400 (170 seats), but were able to receive a number of improvements.

So, the new aircraft already accommodated 189 people as much as possible and underwent significant changes in the design.

The Boeing 737-800 is a low-wing, swept-wing aircraft. A new generation of aircraft was created in order to regain the advantage in the fight with the main competitor - 0. Therefore, serious changes affected primarily the wing structure, control systems and engines.

The wing received a new major difference - special endings (winglets). This design gives a great advantage in terms of efficiency and significantly improves the performance of the liner during takeoff and landing (in terms of takeoff and braking, takeoff speed).

The cabin also received great differences from previous versions, which not only underwent a modified design, but also made significant progress in terms of technical equipment. Thus, traditional analog devices have been completely replaced. At first, beam screens were used, and later - liquid-crystal screens.

New developments have reduced the weight of the aircraft by almost a third, increased flight range and speed, and improved safety in the air.

Two engines are installed under the wing, which operate on turbofan thrust.

There are two power plants (one on each console). Manufactured by CFM International. A series of the applied engines - CFM-56-7B.

Such engines have been installed since 1980, due to their high efficiency and sufficient power at that time. But the design features of the new power plants left their mark on the appearance of the liner. Due to the large diameter, both engines were moved to the pylons under the wing (abandoning the built-in structures). Decreased and ground clearance of the aircraft.

When fully loaded, the distance from the engines to the ground is 46 centimeters. This makes these Boeings low landing (low-wing) and leaves its mark on high requirements for host airports (in particular, the condition of the runway).

Such a low location of the engines, among other things, led to design changes. It was decided to move some mechanisms and parts to the side of the engines (while they were usually located below). This led to some significant changes in the fuselage. It has become narrower and visually a little flattened. This is considered a feature of the new generation Boeing 737s (-600, -700, -800 and -900 series).

Fuel system

The location of the fuel tanks in the models 737-800 is classic. Two are located in the wing of the aircraft (in consoles on both sides). There is also a central tank, on the Next Generation generation it occupies not only part of the fuselage, but also passes into the base of the wing and reaches the pylons on which the engines are suspended.

Fuel consumption is organized in such a way that fuel is first pumped out of the central tank, and then from the wing.

A feature of the Boeing 737 is the inability to dump fuel in case of emergency. To land, you either have to take risks and land the car with the maximum weight, or produce fuel in the air.

Aircraft of the BBJ model range provide for the installation of additional fuel tanks. They can fit in luggage compartments (up to 9 tanks). This method increases the capacity on board for fuel up to 37 tons.

Chassis

The chassis of the Boeing 737-800 differ little from the classic versions, but they also have their own design features.

So, three racks are installed: one is taxiing and is located in the bow, the other two (main) are fixed on the center section. Each rack has two wheels.

A characteristic feature of Next Generation Boeings is their large diameter engines. This feature influenced not only the change in the fuselage, but also led to the redevelopment of the landing gear. They began to be further strengthened and lengthened - to increase the clearance during landing.

A distinctive feature of the Boeing 737 is the rear landing gear that does not close with consoles.

When folded, they are part of the aerodynamic scheme. This measure increases the resistance in flight (though only slightly due to the work of engineers), but is caused by a reduction in additional equipment on board and a reduction in weight. In particular, additional hydraulics for the rear pillars are not installed.

Since 2008, the brakes of Next Generation aircraft have been significantly changed. They began to put carbon brakes on them, which, with less weight and a longer resource, work more efficiently.

Passenger cabin and operating companies

The Boeing 737-800 aircraft is highly popular in the world. He earned special love from low-cost carriers (low-cost airlines), which form for themselves entire fleets of these models of American liners.

The 737-800 is great for medium haul or short haul flights. Therefore, they are most often used within the same continent and it is difficult to find a replacement for them today (except perhaps the Airbus A320).

The Boeing 737-800 is most popular in its home market - in the USA. Most of the largest air carriers are from there:

Southwest Airlines (696 aircraft);
United Airlines (325 aircraft);
American Airlines (328 aircraft);
Delta Air Lines (83 aircraft).

In Europe, the Boeing 737-800 is also popular, although in many airlines it works together with the Airbus A320. The most massive representative of the 800th models is from the Irish low-cost carrier Ryanair (413 aircraft).

In Russia, the aircraft is widely distributed and is used by Aeroflot, Rossiya, Pobeda, Utair and S7 Airlines.

The last of these companies is so ambitious that it orders personalized aircraft at the plant on an individual project, they are called the Boeing 737 800 s7.

The Boeing 737-800 is a narrow-body aircraft (it has one aisle between the rows of seats). The layout of the cabin in the economy class is found in the form of "3-3", and in the business cabin - "2-2".

The maximum capacity of the liners is 189 people. Such a number of passengers can be transported in an aircraft fully equipped with economy class seats.
There are versions of the aircraft with a mixed layout of passenger seats: 12 seats for business travelers and 150 for economy options. The total capacity is 162 people.

Exits from the cabin are provided in the front, in the middle of the fuselage and in the tail of the liner.

It is possible to board passengers and exit on both sides.

The technical characteristics of the Boeing 737-800 are presented in the table:

Length/width (with wing)/height	39.37 m/34.32 m/12.62 m
Fuselage/cabin diameter	3.76 m / 3.54 m (the same for the whole generation)
Ceiling in salon	2.20 m
cruising speed	852 km/h
Range maximum	5765 km
Flight altitude maximum	12.5 km
Empty weight / maximum takeoff	41.4 t/79 t
Fuel	26 000 l
Takeoff/landing run	2241 m/1630 m

Lineup Boeing 737-800

Boeing 737 is used not only for civil transportation. And not only for regular flights. The BBJ2 modification is distinguished by an expensive interior layout (business version, with sofas, trim and low capacity).

The plant works closely with military orders. For them, the company created the 737-800ERX and P-8 Poseidon models.

Place of production

Initially, part of the assembly of the 737 family was carried out at the company's main plant near Seattle. The fuselage and wing were placed in the same place, and the tail section was assembled at the factory in Wichita. Some parts (chassis, technical stuffing) were produced by joint forces or third-party organizations. The final assembly was carried out in Seattle, where the parts of the liners flocked.

Later, the assembly was transferred to Wichita, where both small structural elements and even fuselages with wings were transported by rail.

The scheme with the delivery of parts to the assembly line, tested at the Wichita plant, has been used since 1970 and has been used to this day.

Only today the assembly has been moved further south, to the city of Renton.

prospects

Boeing associates the main prospects for the development of medium-haul transportation with the MAX generation. Since January 2016, final tests have been underway and the first of the Boeing 737 Max models was sold in the spring of 2017. They are also capable of carrying many passengers and are equipped with the latest security systems and avionics.

Already in the short term, they will gradually push out the 737-800 and then 737-900 models from the market.

Conclusion

The Boeing 737-800 is a successful project of an American company, which is distinguished by a very thoughtful combination of high capacity, good performance in terms of economy, flight range and safety.

The liner began to be used by most airlines in the world.

Pilots and passengers note its convenience and safety. Model 737-800 took into account the shortcomings of the past aircraft of the SU family and thanks to this it became so popular. The number of produced cars is so great that it breaks all records. This means that even with the advent of new models, the Boeing 737-800 will be in the sky for many years to come.

Video

The Boeing 737 is classified as a passenger aircraft with a narrow fuselage and turbofan engines. At the moment, he holds the status of the most massive civilian vehicle. In March 2018, the 10,000th copy was assembled in the company's hangars, while the company had a queue of another 4.5 thousand orders.

The start of the production of the machine was given in 1967. Now, according to statistics, about 1200 737s are constantly in the world airspace, 12 aircraft come in for a landing per minute.

Under the Boeing 737 index, not just one model is produced, but more than a dozen.

The history of the development of the Boeing 737 passenger aircraft

The development of a new aircraft was seen as an opportunity to replace the machines of the 60s:

BAC 1-11;
DC-9.

They were intended for short-range flights and had a small capacity. We needed a technique capable of more, as the civil aviation market was constantly growing.

A competition was announced for the development, and Boeing at first lagged far behind competing firms. The drawings appeared at a time when other participants in the competition were already undergoing certification. However, the sales department predicted the creation of about 600 new machines for the market and the development was forced.

The process was accelerated by borrowing some of the solutions from the company's models that already existed at that time:

In particular, the fuselage shape of the 737 was borrowed from these aircraft. Nevertheless, the first tests were failed: when exposed to the load-bearing elements, the wing was torn off by a 95 percent load.

The redesign made it possible to create a new wing, which was distinguished by a large margin of safety, and could also lift the car on short runways. In addition, increased cruising altitude, increased efficiency in terms of fuel consumption. By using the experience of previous developments and a number of their solutions, it was possible to minimize the development time and cost.

The resulting sample of engineering thought had an important advantage over its competitors: the seats were arranged 6 in a row (for others - 5), which significantly increased the capacity.

In early 1965, the completion of the design stage was announced. The resulting car had the following features:

Passenger capacity has increased from 60 planned to 103 seats;
Ailerons of the 727th, the drive of which came from a double hydraulic system;
Identical to the 727 were the elevators, rudders, Kruger flaps and slat;
The 707 had an identical stabilizer tilt setting system that had manual override.

Lufthansa asked to increase the capacity of the aircraft, which was the first to purchase a novelty. Since the end of development, 22 new Boeing 100s have been ordered immediately, and in the spring United Airlines ordered 40 more, but already 200s.

In the company's hangars, the first aircraft was assembled in January 1967.

Description and technical characteristics

The aircraft is a low-wing aircraft equipped with two engines. The wing is swept, the tail unit is single-keel. Under the wings are turbofan engines, which, when the machine is fully loaded, are raised above the runway by only 460 mm.

The air conditioning system uses the auxiliary power unit and motors.

Air is needed to perform the following tasks:

air conditioning of residential areas;
lowering the temperature of the installed equipment, blowing;
for anti-icing system of wings, engines;
used when starting engines.

The role of the air conditioner is performed by the SLE air conditioning system, which has two channels. Cabin air may be used for recirculation.

The extended versions (737-400, -800 and -900 SLE) have a larger cabin, which required a change in the SLE. It has two temperature zones in the cabin in these models, temperature control occurs with the use of more advanced devices.

The Classic and Next Generation engines are equipped with air intakes that are not round in shape. In addition, the engine units are placed in the influx of the wings.

Aircraft power supply is divided into two types:

primary;
secondary.

The first type is based on a system of two alternators that are connected to the engines. They give out voltage of 115 V and frequency of 40 Hz. The power of the installations is 40 KVA, they are not able to work synchronously.

The secondary power supply system provides a voltage of 28 V, and three rectifiers and a large-capacity battery are responsible for generating energy. If necessary, generators of constant frequency and variable speed can be installed on 737 "classic".

The described scheme is used on the "Original" and "Classic" models, but on the NG series, the power supply is carried out according to a different principle:

distribution principles have been changed;
new generators installed;
another battery installed;
pointer devices on the electric control panel are replaced by digital ones.

The generators are combined with a constant speed drive with a power of 90 KVA.

The flight control system of the Boeing 737 also includes primary and secondary. The first one consists of traction with cables, duplicates its booster control, it is possible to switch to a non-booster scheme. The behavior of the machine in the air is influenced by the elevators and rudders, as well as the ailerons. The direction does not have a manual control method, the steering wheel is controlled by the main drive or emergency.

The secondary system has the following nodes:

three outer slats from section pylons;
Krueger slats on two inner sections;
three-slotted, two-section flaps;
5 spoiler sections include flight and ground spoilers, they are activated in appropriate conditions;
adjustable stabilizer.

The NG series features wings extended by 5.5 meters, which made it possible to improve the control system by adding sections of spoilers and slats. Also in the design used new flaps - double-slotted.

The fuel system uses the space of the center section, wings and luggage compartments.

Capacity and consumption depends on the model:

737 Original holds 12.7-15.6 tons (depending on options and modification);
737 Classic holds 16.2 tons;
737 NG holds 20.8 tons, the capacity of the tanks in the center section has been increased;
737 BBJ can be equipped with additional tanks with a total volume of up to 37.7 tons.

It should be noted that there is no emergency drain system, therefore, during an emergency landing, it is necessary to make several circles over the airfield to generate fuel or land urgently with excess weight.

The chassis of the car has a classic scheme - three supports, the front of which is the steering one. Each rack is equipped with two wheels, which are retracted into niches on the center section, but are not closed by doors. This spoils the aerodynamics, but greatly simplifies the layout of the hydraulics.

Boeing 737 flight characteristics

The specific characteristics of the machine depend on the model and class to which it belongs. Only the width of the fuselage and cabin remains unchanged for everyone.

Scheme of the cabin and location of seats

Consider the Boeing 737 interior layout using the 800NG as an example. Armchairs are arranged in 6 rows - three in each, separated by a passage. There are three toilets, two of which are located in the tail section. There is also a large kitchen, another one in front of the plane, it is smaller. There are two exits in front and behind, emergency exits approximately in the middle between the passenger seats - there are four of them, separated by a row of seats.

The distribution of seats is as follows:

Between the front and emergency entrances there are three rows ABC and DEF, separated by a walkway. The first group has 42 chairs, of which 3 with increased legroom, 3 with non-reclining backs. The second group has 39 seats;
Between emergency exits, 6 more seats with increased legroom;
In the back, two identical groups of 51 seats.

The exact layout of the space depends on the specific wishes of the customer. Configurations vary by model. The maximum capacity varies from 103 to 200 seats in MAX-9.

Aircraft safety

The most dangerous moment in the entire flight of an airliner is takeoff and landing. Takeoff weight does not significantly affect the characteristics of the machine, but is taken into account during the takeoff run. If there is an overload, then the strip should be significantly longer than with the minimum mass.

Headwind or tailwind during takeoff does not play a special role, only side wind is taken into account: it should not exceed 19 m/s, otherwise the risk of displacement of massive equipment to the side of the runway increases.

Landing weight is very important: the acceptable value for the Boeing 737 800 is 65.3 tons.

So far, over 200 aircraft have been lost. The first crash occurred in the USA (Philadelphia), the takeoff was canceled by mistake, it was decided that the engines had failed. The tire then skidded off the runway.

Over the years, a total of 5386 people died in air crashes. Terrorist acts involving 737s, in particular, attempts to steal, were committed 115 times, while 326 people died.

More than half of the disasters happened to the Original 100 and 200 family

One of the latest unfortunate events happened in the United States. On landing, the aircraft skidded off the runway and into the river. Fortunately, no one was hurt.

Advantages and disadvantages of Boeing

Given many years of experience in flying, operating and modernizing Boeing airliners, engineers managed to eliminate all serious shortcomings. Basically, the nuances relate to the service and other subjective moments.

The advantages of Boeing are as follows:

The cabin is ergonomic, well-equipped and easy to use for passengers and staff;
Takeoff and landing are easy and with maximum comfort;
Companies using machines maintain a high level of service.

Among the shortcomings are:

Pilots do not receive angle of attack data despite being equipped with wind vanes. This data can play an important role in case of doubts about the reliability of the altitude and speed readings of the computer, if an error occurs when entering the weight values, when the pilots have to taxi from difficult positions in the air or when the mechanics fail;
Safety is reduced due to the lack of restrictions in case of exceeding the permissible temperatures of gases behind the turbine;
When the flaps are extended, the lateral stability is excessive. This reduces comfort when flying in turbulent conditions.

Another important problem is improper maintenance of equipment, which causes a decrease in comfort and an increase in risks, especially with an increase in service life.

Boeing 737 lineup

Airliners were produced and are produced in the form of 4 families, each of which has at least two models.

Original

The first family is called the "Original" - this is the basis from which the era of 737 flights began. There are two versions - 100 and Boeing 737 200.

Boeing 737-100

This is a 1965-69 car that could accommodate no more than 103 passengers. "Sotka" became the base for the entire family of liners.

Boeing 737-200

The car was increased by 2 meters and was able to accommodate more passengers and fly long distances. Its release started in 1967 and lasted until the end of the 80s.

Classic

The Boeing 737 classic family is already more diverse and includes three versions of the aircraft at once.

Boeing 737-300

In the "classic" 300, the fuselage was further increased in length, which made it possible to add passenger seats. It has been in operation since the mid 80s.

Boeing 737-400

In this version, the body continued to lengthen, which required a redesign of the air conditioning system. In return, the companies received even more seats for customers.

Boeing 737-500

Compared to the 300th, the model has become shorter, but the flight range has increased by 5.2 thousand km.

new generation

Further development of the aircraft led to the emergence of the NG family, already represented by five versions.

Boeing 737-600

This "Boeing" was the first modification in the family. It was considered at the time of its appearance as an alternative to 500. However, it did not receive popularity, since it did not differ in efficiency.

Boeing 737-700

It became more successful than its predecessor, as it had a greater flight range and passenger capacity. This model was produced in the form of an even more "long-range" version with the ER index in the name.

Boeing 737-800

This machine came to replace the 300th model, the fuselage is lengthened, it can accommodate 190 people.

Boeing 737-900

The longest version of the family is 42 meters, the number of seats is 190.

Boeing 737-900ER

On the basis of the previous version, a liner with a capacity of 215 people was created. Flight range increased.

MAX

This is a new generation of 737s. The customer received the first aircraft only in 2017.

Boeing 737 MAX 7

This version came to replace the 700 and 700ER models. Unlike previous generations, the airframe of the aircraft has changed slightly, with regard to the entire generation.

Boeing 737 MAX 8

This option is intended for those companies that used the Boeing 737 800. New, more powerful and modern engines appeared at MAKS.

Boeing 737 MAX 9

This aircraft replaces the 900ER.

Boeing 737 MAX 10

The new machine, the largest and most spacious in the family, the first samples should be delivered to customers in 2020.

Thus, the history of the glorious machine continues. Soon the biggest MAX will be released from the hangars!

Despite the abundance of opportunities to get to any corner of the world, one of the fastest and most convenient ways is considered to be traveling by plane. Often, airlines use Boeing 737 series aircraft of various modifications to deliver passengers. The American corporation "Boeing" began to produce these liners from the end of the 90s of the twentieth century (the first tests of the industrial design took place in 1998) as opposed to the legendary model of the entire passenger aircraft "Airbus A320". "Boeing 737-200" (300, 400, 500) were originally produced with a smaller number of VIP-class seats (2 rows of 2 seats on both sides of the central aisle, total - 8 seats) and only in the 737-800 model they became reach the number of 12, 16 and even 20.

Currently, the aircraft has about 10 modifications, including the Boeing 737 800W liner, equipped with wiggles (vertical wingtips upwards) and even a model for the transfer of military personnel. Many companies have equipped their fleets with these aircraft, buying them on lease or on a prepaid basis. The Dubai airline "Fly Dubai" did not bypass them with its attention.

general information

Fly Dubai Aircraft Design

Flydubai is a budget airline established by the Dubai government in 2008 and assigned to the second terminal of the Dubai airport. Since 2009, as a result of acquiring ownership of the aircraft, the organization began to operate regular flights to Jordan, Amman, Beirut and Lebanon. By the beginning of 2014, the number of flight destinations covered by the company, as well as the aircraft fleet, had increased several times and reached 68 different settlements. By the middle of 2014, the fleet of aircraft in use by the airline was replenished with the fortieth unit, the total period of use of which did not exceed 5 years.

Note! The corporate identity of the company's aircraft, designed by designer Martin Snelling, stands out in the sky thanks to the bright orange and blue stripes on the aircraft's body. The former speak of the warmth of relations with passengers, while the latter remind of the vast expanses of blue skies, seas and oceans.

Boeing 737-800 "Fly Dubai" interior layout

From the inside, the aircraft is equipped with a personal electronic entertainment system, a comfortable modern interior with an increased volume of luggage racks, a number of seats and floor-to-ceiling space (allows even professional basketball players to get up from the seat at full height). Flydubai became the first company to receive the Boeing NG aircraft of the third generation (Next Generation) of the most convenient modification 737-800 with a Sky Interior flying cabin.

Economy class seats Boeing 737 800 NG

The cabin of this model of the liner is equipped with the Inflight Entertainment (IFE) system and monitors built into all the boarding seats of the liner, and not just in the VIP-zone seats, as in all the others. The left side of the user-friendly interface includes paid services (duty-free food and shopping, movies, series), while the right side includes non-commercial services in the form of flight information, audio channels and games.

It usually takes passengers no more than 30 minutes to familiarize themselves with the new features of the cabin and the Inflight Entertainment (IFE) system. And the rest of the time can be spent playing games, tracking the location of the liner on an interactive map, making purchases of goods available from flight attendants and ordering coffee, water and any other food without getting up.

Design features and main technical parameters of the liner

Most of the aircraft fleet (21 airliners with economy class cabins for 189 landing seats and 14 aircraft with 12 VIP class seats and 162 economy seats) of Fly Dubai are turbofan narrow-body passenger aircraft Boeing 737-800. The characteristics of an aircraft performing regular air travel are as follows:

double-circuit turbofan engines CFM International CFM56-7B24s with a thrust of 107.6 kN or CFM56-7B27s with a thrust of 121.4 kN, allowing to increase the carrying capacity of the liner;
digital avionics EFIS, North American company Honeywell and 6 multifunctional LCD monitors for displaying all flight and onboard data;
the length of the airliners is 39.49 meters, the wingspan and area are 34.31 m and 125 sq. m. respectively. The height of the aircraft reaches 12.51 meters, and the maximum developed speed is 851-920 km/h. At the same time, the volume of fuel tanks does not exceed 26,020 liters, which allows flights to a distance of up to five thousand four hundred kilometers. The width of the cabin is 3.54 meters, and the number of crew seats does not exceed two;
one-class cabins up to 189 seats and two-class cabins - up to 162 economy class seats (the number of seats may vary depending on the aircraft modification purchased by a particular airline).

Seat selection

Let us consider in more detail the layout of the rows and the layout of the cabin of the Boeing 737-800 "Flydubai" for the optimal selection of a seat for travel. We take into account the configuration of the cabin to determine the best and most comfortable seats, as well as less comfortable, from the point of view of practice, flights over long distances.

Aircraft B. 737-800" of Flydubay may contain seats of one or two comfort classes. The most convenient and safe are:

ergonomic business class chairs;
first row after the VIP zone;
the first rows of the economy class cabin of the aircraft;
15th and 16th row near emergency exits.

The layout of the seats in the cabin "Boeing 737-800" company "FlyDubai"

Description of seats depending on their location in the cabin

Rows: 4 or 1 (if there is no partition separating the VIP area from economy class seats or business class seats), 15, 16 - seats with extra legroom;

Rows: 14, 15, due to safety measures, are fixed in such a way that the backs do not recline;

Rows: 15, 16 due to their proximity to emergency exits are not intended for passengers with children under 16 years old, animals and the disabled.

The number of seats in economy class only and VIP cabins varies from carrier to carrier and model to model. Therefore, it is important to study the parameters of the location of seats in the cabin before buying tickets. It would be useful to know that Pobeda Airlines has in its fleet the majority of aircraft with a similar seating configuration in the aircraft cabin.

Note! The last row of seats in any modification of the Boeing 737-800 is considered the most mediocre in terms of comfort and convenience, since it is located right next to the toilet.

Considering that there are only 3 restrooms in the liner (1 - in the "head" and 2 - in the tail of the aircraft), then a constant queue, and therefore noise, and not always pleasant smells - all this awaits passengers traveling in the last seats. Do not discount the state of turbulence (the area of \u200b\u200bwaves in the air, which creates a specific shaking of the aircraft).

The first rows, if not given over to the VIP zone, are very convenient when traveling. It is always quiet here, the shaking is almost not felt, the places are serviced by stewards in the first place, and also contain a wardrobe and special fastenings for baby carriages. But the very first seats, if the entire aircraft contains only economy category seats, are located immediately after the staff rooms, and, therefore, have a partition in the form of a wall, which will be very inconvenient for people suffering from claustrophobia (fear of enclosed space).

Seats in rows "A" and "F", located near the windows, are contraindicated for passengers who are afraid of heights. The seats located in the center (row "B" and "E") should not be taken by solo travelers, since, in addition to other irritants, they will be "clamped" on both sides by strangers.

Considering the fear of some people before flying, to feel “relative” safety, one should choose seats in the VIP zone, and if it is absent, then in the head of the liner, due to their proximity to the pilots and staff, as well as the seats of the 15th and 16th row due to for their equipment with emergency emergency exits.

Note! The seats of the 15th and 16th rows are among the most convenient, as they are located with a large distance between the rows, but they can only be occupied by adults and healthy persons (without disabilities), traveling without children and pets. In a critical situation, it is they who are assigned the mission of opening emergency exit hatches.

For novice travelers, to get a positive flight experience, the following tips on choosing passenger seats will help:

If possible, do not take tickets for seats in the last row and those that do not recline (How many seats in the Boeing 737-800 have similar functionality limitations, you can find out before purchasing an air ticket).
Before the flight, study the seating chart of the aircraft cabin or ask an airline company representative for advice on selected seats.
Do not choose the first row seats (does not apply to salons containing business class seats) and near the porthole for people who are afraid of confined spaces, flights and heights.
Do not choose places in the center for people traveling alone.

With a careful and responsible attitude to the process of selecting an air carrier company, sitting in the cabin of an airliner and following the above recommendations, a positive flight experience is almost always guaranteed. With the experience of flying, the choice will be given each time easier and easier, and the sensations of turbulence and not always adequate cabin neighbors will no longer be a stress for the psyche.

Every year, airlines increase the number of flights and open new destinations due to the increase in demand for air travel. The cost of tickets is gradually decreasing, the number of hours in the air in the same directions is decreasing. Today, everyone can afford to buy a ticket for this type of transport. But not everyone imagines what the location of seats on board the aircraft looks like, where it is preferable to sit down for a comfortable time in the sky. And there are those who are simply afraid to fly, and detailed information about the structure of the Boeing 737 800 will allow them to be convinced of the reliability and convenience of the aircraft.

Brief information about the Boeing 737 800

Boeing 737 800 is a popular model among top air carriers: in Russia it is Aeroflot, UTair, Nord Wind and others. More than 150 airlines around the world have these models in their fleet, so the developers have tried to make it as convenient as possible. A model was created as a competing product with the Airbus A320. It differs from the previous release of the Boeing 737 line with elongated wings, a new modification of the tail section and an improved engine. The aircraft were put into operation in 1998, and production continues to this day.

Liner device

The model is available in two versions:

Aircraft with budget class seats (maximum 189 seats).
An analogue with a division into business class and economy (maximum 160 seats).

The option with the maximum number of passengers is less convenient for lovers of increased comfort: the width of the cabin is only 3.5 meters, many complain that the aisles between the seats are very narrow. The flight range is up to 5,700 m at a speed of up to 850 km/h, the flight time is 1-3 hours, so it is important for many to have spacious comfortable seats. You can first check the availability of a business class on the plane when booking a ticket on the airline's website.

Features of the structure of the aircraft Boeing 737 800 (189 seats)

Consider the first modification of the Boeing without business class (189 seats).

In the bow are the first 10 rows of seats. It is here that you should choose seats during check-in for a flight (if possible). Less noise from rattling engines, you will be served first during meals and drinks, and you will also be the first to leave the plane after landing.

The 1st row of the aircraft is well suited for passengers with children: here you can place a cradle (you will need to order it from the airline staff no later than 36 hours before departure) and there is a little more space here than between the rows. But the table will not be in front, but will slide out from the side of the armrest.

In the 10th and 11th rows there are places where there may not be a porthole (marked in yellow in the diagram). Rows 13 and 14 have an advantage in the width between the rows, but the seats do not recline and are usually colder there than in the rest of the cabin. Green seats from row 16 will allow passengers to stretch their legs, and the owners of seats in row 31 will not be able to recline their seats, and the entire flight will enjoy the slamming of the toilet door. Also the last 5 rows (i.e. the tail section) tend to shake the most during turbulence.

Wing emergency exit seats not available to all categories of citizens for security reasons. In the event of a malfunction of the aircraft, these passengers must strictly follow the commands of the personnel. List of prohibited categories of citizens for these places:

Passengers with children under 12 years old.
Minor passengers without accompanying persons.
Long term pregnant.
Passengers with pet carriers.
Citizens who do not speak English and the language of the staff.
Disabled and people with disabilities.

Do not worry if you were given these seats, and you fall into one of the categories - before the start of the flight, the flight attendants interrogate the passengers of these two rows and change seats if necessary.

How to choose seats on the Boeing 737 800 (160 seats)

The two-class modification of the aircraft has a zone of increased comfort in the nose of the aircraft, which is clearly seen in the diagram.

Business class passengers sit two on each side, there is a monitor on the backs of each seat (in economy class it is one at the beginning of the row). The seats are very comfortable, wide, the distance between rows is noticeably greater. But the first row is inconvenient due to the proximity to the toilets and the staff room, from where you can constantly hear rustling, voices and slamming the toilet door.

Economy class starts from row 7 and the first seats have the same characteristics as the first row in the single-class Boeing 737 800 model (places for a cradle and children, uncomfortable tables, inability to stretch your legs because of the partition). In the 10-11th row there may be blind windows, and in the 30th row the backs of the seats do not recline due to the back wall. The 13th row will upset those who like to sleep with their backs reclined (all because of the emergency exits from the next row), and the owners of seats in the 14th and 15th rows will be able to stretch their legs between the seats, but bags and backpacks will have to be used after landing.

Experienced travelers recommend finding out the layout of the aircraft in advance and booking the most comfortable (depending on requests) seats. Negligence in choosing a seat can spoil the mood during the flight and affect the overall impression of the trip. Previously, seats were selected at check-in for a flight, now it can be done online a day before the flight.

In the aircraft, the seats are arranged in 2 rows of 3 seats. If you are a big fan of sleeping, reading in silence, or adore looking out the window, then you need to take seats by the window. A great place where other passengers will not ask you to let them out to the toilet. This is especially true for night flights.

For those who are afraid of flying, it is better to take the middle seat or by the aisle. The latter option is also suitable for those who want to stretch or straighten their legs. And you can get up more often without pulling neighboring fellow travelers. Sleeping in places near the aisle is not very comfortable: from time to time the neighbors ask to be let out, then they touch the carts and passengers passing through the cabin.

For those who wish to have a calm flight, it is better not to take seats in the tail section of the aircraft - there is always a busy queue for the toilet and you can hear the slamming of the door, the rustle of food preparations from the personnel area. In the tail section, turbulence and shaking during takeoff are especially strongly felt.

Pet owners should choose seats near the aisle and closer to the staff / toilet area in order to less disturb neighbors and immediately turn to flight attendants for help. For passengers with infants, the first row seats with the possibility of installing a cradle and the absence of seat backs reclining on them are suitable. And the children will be more comfortable there, you can always quickly contact the staff.

If you know that you are flying on a lightly loaded flight, then there is a high probability that there are empty rows in the tail of the aircraft. You can take a seat in the penultimate rows and stretch out at full length on long flights without remorse.
