Airbus A320 is a computer in the sky. The best seats on the Airbus A320: make your flight comfortable

The Airbus a320 is considered one of the most frequently used passenger airliners. Today, there are more than 3.5 thousand aircraft of this series in the world air fleet. The largest Russian air carriers, such as Aeroflot, S7, Rossiya have 50-60 Airbuses in their fleet. Due to its performance, the A320 aircraft fly in the skies of Europe, Asia, as well as the Americas and Australia.

Manufacturer

The Airbus A320 is produced by the Airbus S.A.S. aircraft manufacturing group, its headquarters is located in Toulouse, France, and the aircraft itself is assembled at factories in three countries: France, Germany (Hamburg) and Britain.

Since 2011, another assembly line has been launched - in China. The staff of the Airbus corporation exceeds 50 thousand people. The very name of the liner - "airbus" is translated as "air bus", it was the only acceptable linguistic option for the French management of the company.

Start of release and modification

The most popular aircraft of this series can be considered the Airbus 320, which was designed to compete with the popular Boeing 727 series. The release began with modifications of the A320-100 (capacity 130 people) and A320-200 (150 people). Today, the "A320 line" also includes models 318, 319 and 321 modifications of the airbus.

For the first time, a narrow-body (there is only one passage between the rows of seats in the cabin) novelty from the airbus industrie a320 took to the skies in February 1987. For this aircraft, for the first time in the world, a plane control system was mounted not from the steering wheel, but from external devices via a hydraulic drive system. Despite being classified as narrow-body, the Airbus A320 has one of the most impressive fuselages in size - about 20 cm wider than similar airliner models. This feature makes it possible to make passenger seats even more comfortable and install up to six seats in each row.

Flight characteristics

Liner A-320 has the following technicalcharacteristics:

• wing length - 34.1 m;
• aircraft height - 11.8 m;
• vessel length - 37.6 m;
• takeoff weight - 73.5 tons;
• empty aircraft weight - 42.2 tons (a significant reduction in weight was achieved by designers through the use of light composite materials: plastic reinforced with carbon or fiberglass).

Of the flight characteristics should be highlighted:

• maximum flight range - 6150 km;
• cruising speed - 840 km per hour;
• maximum developed speed - 890 km per hour
• maximum flight altitude - 11.3 km;
• fuel consumption - 2.5 t / hour.

For your information. The cost of 1 unit of Airbus A-320 is about 94 million dollars.

Meating on the plane

• maximum - 180;
• with two-class accommodation - 150.

In the liners of this model, the height of the cabin has been increased, which made it possible to make the shelves for hand luggage more extensive.

The Airbus A320 was the first to use wingtips called sharklets. These parts, about two and a half meters long, are made of lightweight composite materials and serve to improve the aerodynamics of the airliner's wings, as well as increase the efficiency of engines (up to 4 percent). Airbus wings elongated in this way do not prevent them from easily maneuvering on the runway and taxiway. There is a technical possibility to mount sharklets on already produced and flying liners. These details also visually enhance the design of the aircraft, giving it a futuristic, memorable look.

The scheme of seats in the cabin

Airbus cabin layout has two main options. So, the Aeroflot A320 airliner in one of the layouts has a 5-row system of seats for business class, and the remaining seats are intended for economy class. Less used scheme: two-row business class and more more places for the economy.

From 1 to 5 (or 1-2) rows are reserved for business class passengers, 2 seats on each side of the aisle.

6 row (or 3) - economy class seats located in front of the partition between classes. Rows 8 to 10 (12 to 14) are located along the escape hatches (on both sides of the aircraft body). All other rows of seats are ordinary standard business class seats. Toilets are located behind 24-25 (29-30) rows.

Description of seats by blocks of rows

The location of the most convenient seats for flying in the cabin of the Airbus A320 is easier to imagine on the diagram of the liner used by Aeroflot.

The first row of business can hardly be called convenient - the entire flight has to look at the wall. There is no room to stretch your legs, and there will also be no footrests that are mounted on the seats in front. In addition, cradles for babies are usually attached to the partitions, and there is a high probability of listening to children's cries for the entire flight. They may also be disturbed by smells from neighboring toilets and kitchens. One plus is still there - no one will recline the back of the seat to the passenger on his knees.

Seats of the 6th row of the economy class also rest against the wall, which brings the same inconveniences and advantages as for business passengers. The impossibility of reclining the back of the front seat due to the lack thereof is even more pleasing, since in the economy class there is even less space between the rows than in the business class. The disadvantages of these places include the location folding tables not in the back of the chair from the previous row, but in the armrest - this is unusual and not very convenient. In-flight catering service starts from here, so passengers have the opportunity to choose what they like, and not what is left. For passengers with children, the first rows of seats are the best and recommended: for babies, you can attach the cradle to the wall, and with older children, you can not be afraid that the child will kick in the back of the passenger sitting in front.

Rows 8 to 10 (12 to 14) are adjacent to emergency exits, this has both advantages and some inconvenience. The seats in these places are slightly slanted due to the presence of hatches on the sides of the cabin, for the same reason it can be a little colder here (the problem is solved simply - with the help of a flight attendant's blanket). Hand luggage will have to be unequivocally placed on the luggage racks above the seats, because you can’t put anything in front of your feet, because. this will make it difficult to evacuate. Despite these shortcomings, rows 8-10 are the most convenient (although they are not available to everyone: due to the peculiarities of these places, the elderly, pregnant women, the sick and passengers with small children are not placed here - they will not be able to help the crew in emergency situations). Best Places in the airbus a320 aircraft are marked in green on the diagram. This is row number 10 (14), except for seats A and F. They even sell tickets for it with a small extra charge for comfort (the so-called space seats) - due to the location of the seats immediately behind the emergency exit hatches, an increased space is formed where you can stretch legs, while the backs of the seats are easily lowered (but in the previous two rows they are blocked).

The comfort of seats C and D in the 24th (29th) row (highlighted in yellow) has been reduced, by which people constantly walk and wait in line trying to get to the toilet.

The most unfortunate in terms of comfort are seats 25 (30) of the last row (they are marked in red on the interior plan). Since toilets are located through a thin partition from them, all unpleasant smells and sounds will disturb passengers for the entire flight. Those wishing to visit the bathroom will constantly walk and slam the door. There is also no way to recline the seat back. comfortable position. And, as a conclusion, by the last row of the proposed food and drinks, there is practically no choice left. Tickets for these seats can be taken only in extreme cases.

Armchairs in other rows are ordinary, with no special advantages or disadvantages.

Amenities on board

Due to the large weight and high cost equipment, A320 aircraft are not equipped with Wi-Fi based entertainment systems. For passengers, there are screens in the backs of the front seats (they also provide data on the current location of the liner, flight altitude and temperature overboard). Powerful air conditioners work to purify the air, and there are also individual directional lighting devices - quite bright, but not disturbing others. There are two sockets for every three adjacent chairs, gadgets can be charged via a USB port. It should be noted that not all boards are equipped with these amenities, it all depends on the particular liner.

Airbus A-320 continues to be a very popular aircraft passenger aviation in Europe. Manufacturers continue to improve and upgrade it. So at the beginning of 2016, the new Airbus A320-Neo was put into operation, which is distinguished by increased efficiency and reduced engine noise.

Video

The A320 development program was launched in March 1984. The A320 made its first flight on February 22, 1987. It used CFM International CFM56-5A1 engines. After passing flight tests, on February 26, 1988, the JAA (Joint Aviation Authorities) certificate was received and the aircraft began to arrive at Air France. And the airline "" became the first customer from the USA.

The original version, the A320-100, was built in small numbers, but then an improved version of the A320-200 was produced. Improvements mainly concerned the increase in the volume of fuel tanks. The A320-200 received its final certification in November 1988. Since then, the A320-200 has grown into a family of medium-haul airliners, the Airbus S.A.S consortium, based on which the following models have been produced: A318, A319 and A321.

Many technical innovations were made to the aircraft design. A320 became the first passenger airliner on which the Fly-by-Wire control system was installed. The advantage of this system is that a computer with a given program controls many parameters of the aircraft, for example, it does not allow excess angle of attack or overload. The liner is equipped with EFIS digital avionics from Thomson CSF. The A320 also uses a relatively high percentage of composite materials compared to previous models.

The A320-200 is powered by two CFMI CFM56-5B or IAE V2500 turbojet engines with a thrust of 113 kN to 120 kN each.

Aircraft models have different variants of installed engines. The serial number of the modification depends on the type of installed engine. For example: A320-211 uses CFM56-5A1 motors, A320-231 is equipped with IAE V2500-A1 motors, etc.

Airbus a320 salon

Compared to others aircraft in its class, the A320 has a wider cabin, ample cargo space with large doors for easier loading and unloading. A low cost of operation and Maintenance are a pull factor for low cost airlines. For example, the American low-cost airline JetBlue Airways Corporation, located in New York, acquired for its air fleet 233 such machines. Other low-cost carriers with significant A320 orders include Britain's EasyJet Company Limited and Malaysia's Air Asia.

To date, Airbus S.A.S is developing an improved A320 model. The new version of the A320 was named A320neo. The New Engine Option program is the latest step in the A320 upgrade. The Neo modernization program includes such improvements as: weight reduction, a new, modern interior with extended luggage compartment. The new airframe will be made using new composite materials. And thanks to the installation of new fuel-efficient CFM International LEAP-X and P&W PW1000G engines, it is planned to reduce fuel consumption by 10-15 percent.

Compared to previous A320 models, the new A320neo will produce less noise and emissions. The wing of the aircraft will also undergo modifications, in particular the wingtips, which now, according to the standard, will have the shape of a shark fin, the so-called “sharklets”. Such a modification of the wing reduces fuel consumption by 2-3 percent. Thanks to innovations, it will be possible to increase the flight range by 950 km and increase the carrying capacity.

Airbus A320 video

If you want to see photos of the Airbus A320, you will immediately notice that many people have this model in their fleet. Aeroflot is one of them.

If you look at the characteristics of the A320 aircraft, you can easily see why it is in such demand among all companies. Capacity Airbus aircraft The A320 and the weight of the Airbus 320 are all impressive about this aircraft. Passengers themselves speak of it more than positively.

This liner began to be created so that the company would have suitable competitor for and 727. Its developers wanted to make its similar size, but at the same time improve the technologies that were used at that time in aircraft.

Airbus A320-200.

One of the innovations was fly-by-wire control system in the cockpit. This means that handles were introduced instead of handwheels. Also in the very design of the Airbus were applied composite materials.

The aircraft was assembled in Toulouse and then in Hamburg, as it began to be in demand.

March 1984 work began on the production of this aircraft. So the first flight of the new model was carried out in 1987. In 1988 Air France has acquired the first aircraft of this type.

Features of the Airbus A320

It refers to narrow-body types passenger liners , with enough wide fuselage. This aircraft was designed for routes near and far. Him two engines - turbofan, which are located under the wings.

The same liner was the first on which the so-called sharklets. These are special wingtips that allow increase the aerodynamic characteristics of the wings, as well as reduce fuel consumption.

Inside the cockpit.

In addition to innovations in the cockpit, he the cabin of the aircraft has also undergone changes. He more spacious, and the shelves for hand luggage are large and roomy. Also have individual lighting for each passenger in the cabin. A photo of the Airbus A320 cabin is presented below.

The cargo deck has also been expanded., as well as hatches for loading luggage.

Aircraft maintenance is also less expensive. This was one of the reasons for the popularity of this aircraft. The aircraft noise level has also been reduced.

Cabin.

Its flight range is 4900 km. cruising speed reaches 840 km/h. Salon can accommodate up to 140-180 passengers. Empty aircraft weight 42 100 kg.

It is easily recognizable by one small feature - the front landing gear is slightly beveled.

Interior layout

As a rule, the salon has only one central aisle. Available 4 passenger exits and 4 emergency exits.

A typical layout is two seats in a row in Business and three in a row in Economy.

As you can see, due to its characteristics, the Airbus A320 has become very popular not only in Europe and America, but also in Russia and Asia. About 6,092 of these aircraft are currently in operation.

The Airbus A320 is a narrow-body passenger aircraft developed by the Airbus concern. Serial production of the liner continues from 1987 to the present day.

Salon overview and layout of the best places

Airbus A320 with a two-class layout passenger cabin(business and economy) accommodates 150 passengers.

The business class cabin accommodates (according to the passenger cabin layout) six seats, occupying rows with numbers from 1 to 3. There is a wider (compared to the economy class cabin) central aisle, and the seats are arranged according to the “2-2” pattern. The business class is located in the forward part of the passenger cabin of the Airbus A320, has softer seats and a slightly more varied menu than for economy class passengers. The distances between the chairs here are large, which ensures proper rest for the legs even for tall people.

The best seats in business class are in the second row, especially at the windows. Somewhat unsuccessful are the places of the first and third rows. This is due to the fact that the seats of the first row, although they have more legroom, are at the same time located directly at the toilet and utility rooms. This feature causes sometimes heavy traffic here, which can seriously interfere with relaxing holiday. The third row seats are located close to the partition separating the business class cabin from the economy class. The movement of attendants and the noise coming from the economy class can also cause some inconvenience.

Behind the business class cabin is the economy class with a narrower central aisle, as well as seats arranged in a 3-3 pattern. Economy class seats are occupied (according to the scheme) in rows numbered from 4 to 27.

The best seats for economy class are in the fourth row. This is due to their some distance from the noisy middle and somewhat large space for passenger feet. Not the best for the economy class are the seats located at the very end (in the 27th row). Their inconvenience lies in the proximity of the toilet and utility rooms, which can cause a lot of inconvenience. When booking tickets, these not-so-best places should be avoided if possible.

Airbus A320 variants

To date, there are 4 variants of the Airbus A320: A318, A319, A320 and A321.

The Airbus A318 is the most compact of the entire A320 family, with seating capacity ranging from 107 in two-class to 132 in one-class. One of the most important qualities this liner is that it can take off from shorter runways.

It is also worth noting that it was on the Airbus A318 that the advanced on-board systems were first installed, which are now equipped with all aircraft of the A320 family.

Commercial use of the aircraft began in 2003.

The Airbus A319 is a slightly shortened version of the Airbus A320 by removing the last two rows of passenger seats in the economy class cabin. Thanks to this, the aircraft can use a shorter runway. The base model has a passenger capacity of 116 people, but there is another version that can carry up to 156 people.

Operation of the A319 began in 1996.

Airbus A319 has the following modifications:

• Airbus A319LR - the main difference from the base model is additional fuel tanks, which allow to increase the flight range up to 8000 km.
• Airbus A319CJ is a business modification with an increased flight range.
• The Airbus A320 is a narrow-body aircraft with a maximum passenger capacity of 180 people. Commercial use has continued since 1988.
• Airbus A321 is an extended version of the Airbus A320 with increased (up to 220 people) passenger capacity. The aircraft is medium-haul (flight range - up to 5950 km). Operated since 1994.

Specifications A320

Structurally, the Airbus A320 is a low-wing aircraft. The wing is swept. Plumage - vertical single-keel. Power point Airbus is represented by two turbofan engines, the brand of which depends on the model of the aircraft.

The Airbus A320 was created as a replacement for the obsolete A300 aircraft of the Airbus concern, as well as to compete with the Boeing 727 and Boeing 737 aircraft that had gained at that time (mid-80s of the XX century). The main innovation was the complete modernization of on-board electronics, as well as an improved dashboard: cathode ray tubes were used instead of pointer instruments.

Another important difference between the A320 family and the early Airbus aircraft is that instead of standard steering wheels for pilots, a sidestick (side control stick) was used, which, coupled with modern electronics at that time, made it easier to control the aircraft and limit its crew to two pilots.

Flight performance of the A320 family aircraft:

The Airbus A320 is a family of short and medium haul passenger commercial twin-engine aircraft manufactured by a European company. Airbus Industry. It consists of A318, A319, A320, A321 airliners, as well as ACJ (Airbus Corporate Jet) business class models. The A320 is sometimes referred to as the A320ceo (current engine option). The assembly of these models takes place at the company's factories in Toulouse (France) and Hamburg (Germany). The family of aircraft can carry up to 236 passengers and has a maximum range of 5,750 to 11,100 kilometers, depending on the model.

Aircraft modifications A320

During the production of the liner, several modifications appeared:

• A321. The model was the first derivative of the A320, released in 1988. The fuselage length was increased by 6.94 meters. Maximum takeoff weight increased by 9,600 kg and amounted to 83,000 kg. The first flight of one of the prototypes took place on March 11, 1993.
• A319. This is a shortened version of the model. In comparison, it has a 3.73 m shorter fuselage and a simplified wing. Has less weight. It is capable of transporting 124 people over a distance of 6,650 km (or 6,850 with the new Sharklets winglets. On April 23, 1995, the assembly of the first liner of this type began.
• A318. It is the shortest aircraft in the series. It can carry 107 passengers in a 2-class layout (maximum - 132) for a distance of up to 5,750 km. It made its first flight in July 2003. Can be used on short runways, as opposed to similarly sized aircraft.

In 2011, Airbus was introduced with special sharklets wingtips resembling a shark's fin, hence the name.

They are designed to improve the aerodynamics of the aircraft by increasing the effective wing aspect ratio and reducing the induced drag that is created by the vortex shedding from the end of the swept wing.

The A320 aircraft operates, depending on the modification, on CFM International CFM56 (A 320-21x series) or IAE V2500 (A 320-23x series) engines. With a typical two-class seating arrangement, it is capable of carrying up to 150 passengers over a distance of up to 6,100 kilometers

The first flight took place on February 22, 1987, since then 7,533 aircraft have been produced. The main competitor is the Boeing 737.

The interior layout options are as follows:

• Airbus A320-100
• Airbus A320-200

A total of 21 copies of the 100th series were manufactured and delivered to airline Air Inter.

Of the main changes in the 200 modification compared to the 100 series, it is worth highlighting the appearance of special Whitcomb washers on the side ends of the wings and the expansion fuel tank to increase the flight range of aircraft.

The passenger capacity of both options is the same - 150 seats, classes differ only in flight range and load.

In the first half of 2003 Skytrax (UK) carried out a study to find out the preferences of passengers. As a result of the study, more than 69 thousand people were interviewed, who had to answer questions regarding various criteria (engine noise in the cabin, seat comfort and distance between rows). As a result, about 59% of respondents recognized the cabin of the Airbus 320 as the most comfortable. Another nominee at the same time - "Boeing-737" - scored a little over 25% of the vote.

WITHinterior planAirbus A320

Different places in the cabin have their pros and cons. Many people prefer to choose seats near the windows to admire the opening landscapes. But the disadvantages of such places can be called the need to disturb the neighbors in order to go to the toilet. The advantages of aisle seats include freedom of movement, but you will have to endure anxiety from neighbors who need to go to the restroom.

During the production and use of the aircraft, a large number of various modifications of the cabin of the airbus. The Airbus A320 is a narrow-body aircraft with one central aisle, four passenger entrances and four emergency exits.

The Airbus 320 can accommodate a maximum of 180 passengers. In the standard 2-class layout (2+2 in business class and 3+3 seats in economy class), up to 150 passengers can be accommodated in this modification.

Best Places Airbus a320 .

When choosing a cabin with one class - economy, it is necessary to take into account the following recommendations when choosing seats:

• Passengers seated in the front row can receive in-flight meals and drinks the fastest. Also, the first row provides the most legroom, there are no front-seated passengers. Also, those traveling in the front row can exit the cabin the fastest when landing. The disadvantage of such places is the reduced width of the seats, due to the fact that the tables for eating are attached to the armrests.
• In the 12th and 13th rows there are emergency exits, which gives the greatest legroom for seated passengers, but the distance of reclining the backs of the seats is reduced.
• Seats in the tail are considered the worst due to the fact that the backs of the seats most often do not recline, and the kitchen and toilets are located nearby. But this can be a plus, as some prefer to choose places precisely because of the proximity of the toilet.

Note! Salon schemes various airlines may differ, so you should study the seating arrangement on the website of the air carrier.

The scheme of the cabin with a business class was taken from the official website of the Aeroflot airline (Moscow), since it is she who is the most in demand among various airlines. As follows.

The manufacturer Airbus a 320 seats in the cabin provides for two passenger accommodation schemes:

• Location with 20 seats in business and 120 in economy.
• Location with 8 business seats and 150 economy seats.

Business Class

The first seat installation scheme with 5 rows of business class. The most comfortable are the places in the middle. The chairs are wide and comfortable, there are footrests, which is convenient for long flights. The seats recline strongly, which allows you to comfortably spend the time of the flight. A separate toilet is provided. On the last row there is a partition that separates the business layout from the economy class.

Economy class

The most comfortable are the seats of the 6th row, since there is a large distance between the wall separating the salon and the chair in order to stretch the legs. From these places, in-flight meals and drinks are served, and therefore the greatest choice is provided, in contrast to the tail section passengers. The downside is the need to go to the toilet through the entire cabin of the aircraft.

The 8th row seats are in front emergency exits, in connection with which the backs practically do not recline. A similar situation is in the 9th row, which is also located in front of the emergency exits. The seats provide plenty of space for those in front, which allows you to freely go to the restroom.

The seats of the 10th row are located near the emergency hatches, but unlike the 8-9 rows, it allows you to freely recline the backs of the seats. At the same time, many complain that the seats themselves are not very comfortable for long-distance flights. Of the minuses: these places have restrictions, for example, tickets for this row are not sold to people with handicapped, passengers with children or animals, pregnant women, as well as teenagers under 16 years old. Do not place in front of you or under seats. hand luggage, bags, suitcases.

The 10th - 23rd rows, inclusive, can be called comfortable, but you need to carefully weigh all the above pros and cons to choose seats near the windows or seats in the central aisle. For example, lovers social networks, beautiful photos and landscapes, it is recommended to choose places near the windows, but you will have to constantly disturb the neighbors to get out. Should be considered weather and time of day, since at night the probability of taking beautiful pictures is extremely small. In addition, it must be taken into account that in 15-20 rows the entire view overlaps the wing of the aircraft.

People who are afraid of flying, as well as those traveling with children, are advised to choose seats in the aisle.

The 24th and 25th rows are the least comfortable in many respects. This is due to the fact that all passengers going to the toilet will pass by, which is extremely uncomfortable. Passengers in the 25th row will have to experience this to the maximum extent, since queues often form at the toilets, people knock on doors, they can hurt the passengers of this row. The backs of the seats practically do not recline. You will also have to endure the wafting unpleasant odors and sounds.

Airbus A320 seats in the cabin of other airlines

S7

A two-class layout is practiced here: this is business (8 seats) and economy (150 seats). Business class passengers are offered individual meals. Food and drinks are served from the 3rd row, so it is recommended to choose seats closer to the start. It is advisable to choose the 11th row, but be prepared for the restrictions associated with the prohibition of placing bags under or in front of the seat, as well as observe safety.

Ural Airlines

Rows 1-3 are reserved for business class. Next comes the economy, which is standard, the scheme is similar to that described above for Aeroflot. In rows 9-10, the backs do not move, but there is plenty of legroom. Experienced travelers recommend row number 11, but there are no armrests for seats A and F.

wizz Air

All aircraft of the airline are presented with the same cabin layout for 1 class and up to 180 seats. Best and worst places are identical to the 1-class scheme of Aeroflot. But there are some differences in conditions. Since Wizz Air is a low-cost carrier, they do not provide boarding passes During registration. But in this situation, there are several ways out of the situation:

• The company provides priority boarding services, it is called Wizz Xpress priority boarding. The system provides the possibility of initial boarding, before other passengers and the possibility of choosing a seat if it is not already booked.
• There is such a service as the ability to reserve seats for a fee, usually rows 1-2 and 12-13

Airliner Airbus A320 is one of the most common models in the world. Although the aircraft was developed back in the 80s of the last century, it remains comfortable for flights of any duration and range. It is enough to correctly approach the choice of the best places. It is always necessary to clarify which Airbus A320 cabin layout is presented in the airline on which the trip is planned, since they can vary significantly. It is necessary to clarify how many seats the carrier has allocated for each class. All experienced travelers we recommend that you familiarize yourself with the location of seats in the cabin and its division into classes on the carrier's website.
