The weight of a Boeing 777 with passengers. How it's made, how it works, how it works. Comfortable working conditions for the crew

The Boeing 777-300 is the world's largest twin-engine turbofan passenger airliner, designed for long-haul flights (flight range up to 11,000 km). This model was launched into commercial operation in 1998, the first aircraft was delivered to Cathay Pacific.

Currently, the Boeing 777-300 is included in air parks the main airlines in the world operating long-haul international flights: Emirates, Etihad Airways, American Airlines, All Nippon Airways, Air Canada, Air China, Air France, Aeroflot, Rossiya and others.

The liner can accommodate from 305 to 550 passengers, depending on the cabin layout. Capable of reaching speeds of up to 945 km/h. Dimensions of the aircraft: length - 73.9 meters, wingspan - 60.9 meters.

Modification of the Boeing 777-300ER - with an increased flight range of up to 14,600 km, a larger wingspan - 64.8 meters.

Aeroflot

Aeroflot operates 16 Boeing 777-300ER aircraft. Full list boards: VP-BGB, VP-BGC, VP-BGD, VP-BGF, VP-BPG, VQ-BQB, VQ-BQC, VQ-BQD, VQ-BQE, VQ-BQF, VQ-BQG, VQ-BUA, VQ-BUB, VQ-BUC, VQ-BQM, VQ-BIL.

The layout of all Aeroflot aircraft of this model is the same. There are 3 classes: business, comfort and economy.

Below is a diagram and details about the best seats on Aeroflot’s Boeing 777-300 in all classes.

Business class Boeing 777-300ER at Aeroflot

The most comfortable business class for long-haul flights is located in rows 1-5. The total number of seats in this class is 30, they are arranged in pairs (the configuration in each row is 2-2-2).

All chairs are spacious, leather upholstered, conveniently adjustable, have several positions and even fold out into a horizontal bed.

Dimensions of each chair:

• Length - 195 cm,
• The width of the double block is 144 cm,
• The distance between the armrests is 52 cm,
• The space to the seat in front is 150 cm,
• Passage width - 42 cm.

Other business amenities: large individual monitors with Thales entertainment system, chef's menu, refreshments and alcoholic drinks during the entire voyage.

Separate business class lavatories are located at the front of the cabin.

Comfort class

There are seats in rows 11 - 16, their total— 48. Layout of seats in a row: 2-4-2.

Characteristics of places:

• Seat width - 49 cm,
• The distance between the seats is 96.52 cm,
• All seats are equipped with a USB port and socket,
• 10.6" personal monitors with built-in Thales entertainment system.

Economy

In economy class there are rows 17 - 51.

The best seats in the economy class of Aeroflot's Boeing 777-300ER are Space+, their location is A, B, C and H, J, K on rows 24 and 38, that is, a total of 12 passenger seats. The main advantage of these seats is the increased distance between the rows, you can freely stretch your legs. Compared to regular economy class seats, to fly on Space+ you will have to pay 1000-4500 rubles more or take advantage of offers bonus program airlines.

Seats at the beginning of economy are also considered successful - on the 17th row, where there is also a little more legroom.

When choosing among regular seats according to the Boeing 777-300 cabin layout, Aeroflot has a general rule:

• You should take it from the porthole (A, K) if you are going to get up only in case of emergency or want to enjoy the view (but no one guarantees it - it depends on the time of day and the weather), the obvious advantage is that you will not be disturbed by other passengers who need to get up;
• At the aisle (C, D, G, H) - you can freely get up without waiting for your neighbors in the row, but this comes with a minus: if the passengers nearby turn out to be restless, you will have to get up and let them through;
• The worst seats are always considered to be the middle ones: no personal armrests (we can only hope for passenger ethics), no free access to the porthole and passage. The second option for bad places is near the toilets.

Nordwind Airlines (Nordwind, North Wind)

The Nordwind fleet uses an improved Boeing 777-300ER model. The interior layout is three-class.

Business Class

Number of seats - 38.

Nordwind's business class is divided into two parts by the kitchen area: there are 22 seats in the bow of the plane, and the remaining 16 are behind the kitchen. The best seats in business class are considered to be the first places in each of the two conventional sectors (rows 1 and 8). Layout diagram: 1-2-1. Each seat converts into a full-fledged horizontal bed.

Comfort class

There are 63 seats in comfort class.

Rows 20 - 27, of which 20 - 23 are premium.

Seat diagram in the Boeing 777-300ER in the configuration from Nordwind Airlines: 2-4-2, for the 20th row - 2-3-2.

Economy

Best seats - 18 seats with increased legroom: rows 45 and 60 - A, B, C, H, J, K; rows 46 and 61 - D, E, G (in addition, in front of these seats there are mounts for bassinets - an advantage for passengers with children).

Other good seats in economy are at the window or at the aisle, closer to the exits and not near the toilet.

Russia

The layout of Rossiya Airlines flights is different - there is only business class and economy class without an intermediate comfort class sector. The carrier practices two options for seat placement, a special one for the EI-GET board.

Seats in Rossiya business class on Boeing 777-300/-300ER:

• 1st row - Super Space seats, the best on the entire flight, 4 seats;
• 5th and 6th row - 14 seats, classic business class.

Business class on board EI-GET - 21 seats, rows 1-3.

Economy class:

• from 21 to 61 rows;
• The best seats in economy (with increased legroom) are Space+, rows 21, 36, 49.

The numbering of economy class rows on board EI-GET is from 4 to 49. The best seats (Space+) are located on rows 4, 7, 22, 36.

Depending on the layout, this aircraft has 11 or 12 toilets.

Emirates

Emirates has operated Boeing 777-300 aircraft since 1999. Currently, the core of the Emirates fleet is the improved Boeing 777-300ER aircraft; their number is approaching 130 and continues to grow.

Wrote in July 26th, 2014

It is the world's largest twin-engine jet passenger aircraft. The Boeing 777 set an absolute range record for passenger aircraft: 21,601 thousand km! Boeing 777 (“Triple Seven” or “three sevens”) - this aircraft was developed in the early 1990s, made its first flight in 1994, and has been in operation since 1995. The Boeing 777 was the first commercial airliner to be designed 100% by computers. And this is the safest long-haul airliner in the history of aviation!

I flew on three sevens only once - from Dubai to Male with Emirates airlines and then I was surprised to learn that they saved a lot on the layout of the economy class cabin, we will put one additional seat in a row, reducing the width of the others! In this report I will talk about the history of creation, design features and show the passenger cabin of the largest operator of this type of aircraft in Russia.

History of creation:

In the mid-1970s. The three-engine 777, which was intended as a competitor to the McDonnell Douglas DC-10 and Lockheed L-1011. This aircraft was conceived as a modified version of the 767 with a redesigned wing and tail section. It was planned to create two main options: a short-haul aircraft, which would be capable of carrying up to 175 passengers over a distance of 5,000 kilometers, and an intercontinental airliner, carrying the same number of passengers over a distance of up to 8,000 kilometers.

Work on twin-engine aircraft soon began, but the 777 project was frozen, as difficulties arose with the design of the tail section of the aircraft, and the company also decided to focus on the more commercially promising 757 and 767. As a result, when both aircraft began to roll off the assembly line, it became Clearly there is a missing link in Boeing's aircraft line. There was an urgent need to have an aircraft that would be in the niche between such machines as the Boeing 767-300ER and Boeing 747-400.

At first, Boeing planned to simply modify the 767, resulting in the so-called 767-X concept. It was in many ways similar to the 767, but had a longer fuselage, a larger wing and could carry about 340 passengers over a distance of up to 13.5 thousand kilometers.

1.

But airlines were not impressed with the new aircraft. They wanted an aircraft capable of flying shorter distances and with a cabin configuration similar to the Boeing 747, which, in addition, could be changed by adding or removing the required number of passenger seats in a particular class of cabin. Another necessary condition was to reduce operating costs - they would have to be significantly lower than those of the 767. As a result, the original project was heavily redesigned and the twin-engine Boeing 777 was born.

The Boeing 777 was the first commercial airliner to be designed 100% by computers. During the entire development period, not a single paper drawing was released; everything was made using a three-dimensional design system.

Development of the aircraft began in 1990 and the first order was immediately received from United Airlines. In 1995, the first 777 began commercial flights. Currently, the 777-200LR is the aircraft capable of performing the longest passenger flights in the world.

2.

Modifications:

The 777-200 was the first modification of the aircraft and was intended for Segment A. The first 777-200 was delivered to United Airlines on May 15, 1995. With a range of 5,235 nautical miles, the 777-200 modification was aimed primarily at US domestic carriers. A total of 88 different aircraft of the 777-200 modification were delivered to ten customers. Airbus's competing model is the A330-300.

4.

The stretched version of the 777-300 was intended to replace the Boeing 747-100 and Boeing 747-200 aircraft. Compared to older versions of the 747, the stretched version has similar passenger capacity and range, but uses a third less fuel and has 40% lower operating costs. The fuselage of the 777-300 is extended by 11 meters compared to the basic modification of the 777-200, which allows it to accommodate up to 550 passengers in a single-class configuration. The modification's maximum range is 6,015 nautical miles, allowing the 777-300 to serve heavily trafficked destinations previously served by the 747.

777-200ER

Modification 777-200ER (“ER” means Extended Range, increased range). The 777-200ER has increased fuel capacity and maximum take-off weight compared to the 777-200 modification. Designed for international carriers and transatlantic flights, the "nf" modification has a maximum range of 7,700 nautical miles (14,260.4 km).

777-200LR

The 777-200LR (“LR” stands for Longer Range), a Segment C model, became the world's longest-range commercial airliner in 2006. Boeing called this model the Worldliner, indicating the airliner's ability to connect almost any two airports. The modification set a world record for the longest non-stop flight among commercial airliners - the flight range is 9,380 nautical miles (17,370 km). The 777-200LR modification is designed for ultra-long flights, such as Los Angeles - Singapore or Dallas - Tokyo. The 777-200LR has an increased maximum takeoff weight and three additional fuel tanks in the rear cargo compartment.

777-300ER

The 777-300ER (“ER” stands for Extended Range) is a modification of the 777-300. The modification has beveled and extended wingtips, new main landing gear, a reinforced nose strut and additional fuel tanks. The model's standard GE90-115B turbofan engines are the most powerful jet engines in the world today, with a maximum thrust of 513 kN. The maximum range is 7,930 nautical miles (14,690 km), made possible by increased maximum take-off weight and fuel capacity. The 777-300ER's fully loaded range is increased by approximately 34% compared to the 777-300. After flight tests, the introduction of new engines, wings and an increase in take-off weight, fuel consumption decreased by 1.4%.

And all the modifications in the visual series:

10.

A good illustration for comparing scales is the 737 in front. Please note that the diameter of the GE-115B engine installed on the 777 model is only 30 cm less than the width of the Boeing 737 cabin!

11.

Design elements:

The design of the aircraft's airframe includes the use of composite materials, which account for 9% of the weight of the structure. The interior floor and steering wheels are also made from such materials. The main part of the fuselage has a circular cross-section and at the rear merges into a blade-like tail cone, which houses the auxiliary power unit.

17.

The airliner also has the largest landing gear and the largest tires ever used on a commercial jet airliner. Each tire on the 777-300ER's six-wheel main landing gear can support 27 tons, which is more than the tire load on a Boeing 747-400!

18.

19.

20.

The aircraft has three redundant hydraulic systems, of which only one is needed for landing.
In the wing fairing under the fuselage there is an emergency aircraft turbine - a small propeller that extends out of the aircraft in emergency situations to provide minimal power.

The General Electric GE90 engines powering the Boeing 7777 are the largest and most powerful jet engines in aviation history.

And all five Boeing 777-300 of Transaero are equipped with RR211 Trent 892 engines from Rolls Royse:

22.

Cockpit:

The cockpit is very spacious. The Boeing 777 in all modifications is a long-haul airliner capable of serving non-stop commercial flights lasting up to 18 hours. However, regulations of various aviation regulatory bodies, professional and trade union organizations limit the continuous work time of crew and flight attendants.

26.

Interior:

The 777 interior, also known as the Boeing Signature Interior, features curved lines, extended overhead bins and indirect lighting. Seat configurations range from 4 abreast in first class to 10 abreast in economy class. The size of the windows - 380x250 mm - was the largest of any commercial airliner until the introduction of the 787.

Each airline has its own passenger cabin layout. It depends on certain customer requirements, and not on the type of aircraft!
Please note that in economy class, Transaero has one less seat in a row than, for example, Emirates (!) and Aeroflot. This means that the chairs themselves are wider and more comfortable!

Let's take a look on board the Boeing 777-300 of Transaero Airlines. EI-UNM flew with Singapore Airlines and was transferred to Transaero in 2012. The interior has been completely updated, with a Lumexis entertainment system installed throughout. The upholstery uses wear-resistant Alcantara material, and the seat manufacturer is the Italian company Aviointeriors.

Safety:

This airliner is considered the safest aircraft among all long-haul airliners. During its 18 years of operation, the Boeing 777 suffered eight incidents, including one crash and two hijacking attempts. On July 6, 2013, the first plane crash with human casualties occurred. An Asiana Airlines Boeing 777-200ER, flying from Seoul to San Francisco, crashed while landing at San Francisco Airport, hitting the end of the runway with its tail. 2 people died.

Boeing 777 in Russia:

In Russia, the largest operator of Boeing 777 aircraft is Transaero. This company has 14 aircraft in its fleet: 5 Boeing 777-300, 9 Boeing 777-200ER. In addition to Transaero, this aircraft is in the fleet of Aeroflot, Nordwind and Orenair.

The Boeing 777 is considered one of the largest passenger aircraft over the past 20 years in Russian and world aviation. It is also called Boeng T7, which means Triple Seven, or “Three Sevens”.

The largest number of these airliners are operated by Transaero (14 aircraft) and Aeroflot (16 aircraft).

Boeing 777 interior diagram, best places for flights, specifications- all this is in this article.

Short description

This Boeing model is the very first in history; its design was developed in the 90s of the last century without paper drawings, entirely on a computer using special programs.

This is the most reliable airliner in the history of aviation, which carries out long flights without a single stop.

The Boeing 777 belongs to the wide-body passenger aircraft. It has been in operation from 1995 to the present day.

The capacity is 305-550 people, the flight range is 9,100-17,500 kilometers.

Technical characteristics of the Boeing 777

It is the largest airliner in the world with only 2 engines. These are powerful General Electric gas turbine engines. The landing gear consists of 6 wheels, which makes it different from other aircraft.

Let's look at the technical characteristics of the Boeing 777 for modifications 200 and 300.

Interior and interior layout

The Boeing 777, as noted above, has several varieties. Each of the modifications has 3 or 4 salons - each has its own layout, which directly depends on the customer.

The interior of the cabins is dominated by curved lines, indirect lighting, and wide luggage racks. The size of the porthole relative to the earlier ones is 380x250 mm.

Economy class capacity is up to 555 people. The seats are arranged 10 in a row. Compared to the first Boeing 777 models, since 2011 the interior has been modernized, making it more modern.

In business class, the seats are arranged 6 in a row, and they fold out into a full-size bed, which is very convenient during long flights. Due to the fact that the total number of seats is smaller than in economy class, there is more space here.

Imperial class is designed for the most comfortable and expensive flights. Increased attention Additional services, best cuisine- all this for special guests.

The interior layout of a Boeing 777-300 operated by Aeroflot is shown in the photo below.

The best seats on the plane

Depends on the overall equipment of the cabin. When purchasing tickets, you can choose any seats, but it is preferable to find the most convenient ones so that the flight is pleasant and comfortable.

The best seats are located near the emergency exits: there is additional legroom. Convenient places in the Boeing 777-300, those located in rows 11-16 are considered - these are places where there are 3 seats in a row (except for those next to the toilet). Good places located near the aisle - there is an opportunity to stretch your legs for a short time, but with pleasure.

- if the modification provides double seats near the window, then when flying in pairs it is better to choose them;

In economy classes, the closer to the nose of the plane, the wider the distance between the rows of seats;

Those in the tail shake the most, those near the wings shake the least;

If the airliner is not fully loaded with passengers, then there are fewer people in the tail and, accordingly, more space.

Of course, these are average figures, since different airlines there are some nuances in the design of the cabins of the planes they own, and it doesn’t matter that they are essentially the same Boeing 777.

"Transaero"

The Russian aviation company Transaero owns 14 Boeing 777 aircraft. Of these, 9 are modifications of the Boeing 777-200.

This company uses configurations with a passenger capacity of 306 and 323 people, 4 and 3 cabin classes, respectively.

On a passenger aircraft there are usually only 3 classes. But the airline company supplements the standard set with additional subclasses.

In Transaero they are as follows:

Imperial;

Business class (premium);

Economic;

Tourist.

A photo of the interior diagram of the Boeing 777 (Transaero) modification 200 is presented below.

In imperial class, all seats are as comfortable as possible for flights. There are only 12 seats in the cabin, which can be transformed into a bed if necessary and desired. Near each seat there is an LCD screen and a table for eating or working on a PC. Exit to the bathroom directly from the salon.

Business class (premium) contains 14 soft and comfortable seats. But in the fifth row there are seats whose backrests recline to a limited extent.

Economy class is a spacious cabin with big amount comfortable chairs.

There are several places here that are not as convenient as the others: near the bathrooms, near partitions and emergency exits (10th, 29th rows). The backrests of these chairs are limited in reclining.

Tourist class is a type of economy class. There are many comfortable seats here (for example, row 30, A, B, H, K). Less comfortable seats include seats C, D, E, F, G in the 30th row, 42nd and 43rd rows at the end of the cabin.

Aeroflot

This airline's Boeing 777 for long-distance flights sends modification 300. The passenger capacity of these airliners is about 400 people, 3 cabins, 3 classes:

Comfort;

Business class is located at the front of the aircraft. There are 30 chair-beds in the cabin, arranged in a two-two-two pattern. The cabin has its own improved menu, drinks, Internet, a retractable table for working at a PC, the ability to charge a mobile phone or computer, and an individual approach to passengers.

The comfort class cabin seats 48 seats. These are rows 11-16. Comfortable seats with a width of 49 cm allow you to fly in comfort. Near each chair there is a retractable footrest, which allows you to recline. Provides individual lighting, table, monitor, charging socket mobile phone. In the 11th row there is fastening for a baby cradle. You can pre-order baby food separately. Not the best comfortable places of this class are located near the toilet.

Economy class is the most crowded, with a passenger capacity of 324 people. The seats are arranged in a two-four-two pattern. For each passenger, Aeroflot provided a blanket, pillow, slippers, and a sleep mask. There is a monitor to brighten up the flight while watching a movie or listening to music. It is possible to use the Internet for an additional fee. The width of the seats is 43 cm. There are mounts for a cradle in the 17th, 24th, and 39th rows. You can ask for games and books for children - this is provided by the airline services.

The Boeing 777 is a long-range twin-engine airliner with a wide fuselage. The aircraft has more than three hundred passenger seats and, depending on the modification, can fly a distance from 9,695 kilometers to 21,560 kilometers. Its characteristic feature is the presence of jet engines with the largest diameter in the world. This is approximately 3.5 meters. Eight leading air carriers were consulted before the aircraft was built. The group's first meeting took place in January 1990. It included such airlines as: Japan Airlines, American Airlines, British Airways, Cathay Pacific Airways, Delta Airlines, All Nippon Airways, Qantas United Airlines.

Boeing 777 photo

The Boeing 777 was designed to replace the previous generation of wide-body aircraft, as well as to fill the gap between the Boeing 767 and Boeing 747 models. It is one of the first aircraft from the Boeing aircraft manufacturer to be equipped with the Fly by Wire digital control system. It is also the first commercial passenger aircraft designed using computer technology. Individual components of the aircraft were developed using 3D CAD CATIA software developed by IBM and Dassault Systemes.

On October 14, 1990, United Airlines placed its first order for 34 Boeing 777s, worth $11 billion. On January 4, 1993, the first “triple sevens” began to be produced. And on April 9, 1994, the first Boeing 777 was produced with serial number WA001. The first flight took place on June 12 of the same year. Test flights were carried out over the next eleven months. Nine aircraft were tested in different climatic conditions from the arid deserts of Edwards Air Force Base in California to the cold of Alaska. On April 19, 1995, after passing all tests, the Boeing 777 received a certificate of airworthiness from the Federal Aviation Administration (FAA) and the Joint Aviation Administration (JAA).

The Boeing 777 is available in two lengths. The base model 777-200 has a length of 63.7 meters, which entered service with United Airlines in 1995. After two years, a model with an extended flight radius was released - 777-200ER (Extended Range). This model first entered service with British Airways. The second version of the Boeing 777 is the 777-300 model. This is a version extended by 10.1 meters compared to the 777-200 model, which can accommodate up to 550 passenger seats. This version began flying in 1998.

Boeing 777 interior diagram

In 2004, a version was released - 777-300ER. This version allowed longer flights than the 777-300. And in 2006, the airline received a Boeing 777-200LR (Longer Range). At this time he became passenger airliner with the longest flight range. This model was called "Worldliner". And since 2009, the cargo Boeing 777F (Freighter) began flying. The 777F, 777-300ER and 777-200LR are powered by General Electric GE90-115B engines. Also, to reduce fuel consumption, the curved wingtips became slightly larger. All other models are equipped with GE90, Pratt & Whitney PW4000 engines, or RollsRoyce Trent-800 engines. The cockpit is equipped with multifunctional Honeywell LCD screens. The wings are angled at 31.6 degrees to achieve an optimal cruising speed of Mach 0.83. Each 777-300ER main landing gear tire can carry a load of nearly 27 tons. There is also a modification for the Air Force. This is a KS-777 model used as an aerial tanker.

After 2000, the Boeing 777 became the best-selling model of the manufacturer of the same name. The most common variant purchased by airlines is the 777-200ER.

- a family of wide-body passenger aircraft for long-haul airlines. The aircraft of the family are among the largest passenger aircraft.

The Boeing 777 is a twin-engine turbojet low-wing aircraft with swept wings and a single fin.

It is the first aircraft to be designed entirely without paper drawings, but only using 3D computer graphics.

The first base model Boeing 777-200 aircraft entered service with United Airlines in 1995. Later, versions with increased flight range Boeing 777-200ER (extended range) and Boeing 777-200LR (longer-range) were also released.

In 1998, Cathay Pacific Airways launched Boeing 777-300 aircraft, which differed from the previous model in having a longer fuselage and increased passenger capacity. Since 2004, a longer-range version of the Boeing 777-300ER has also been produced.

Based on the Boeing 777-200LR Worldliner, a cargo modification, the Boeing 777 Freighter, has been developed and is being produced.
Currently, the Boeing Corporation is developing a modernized version of the aircraft under the symbol Boeing 777X, which will be equipped with new engines and a wing made of composite materials.

Boeing 777-200 is an aircraft for transporting 300-400 passengers over a distance of up to 6 thousand kilometers (basic version), 11 thousand kilometers (777-200ER) and 14 thousand kilometers (777-200LR).

Boeing 777-300 (Boeing-777-300) - a version with an extended fuselage that can accommodate up to 450 passengers, a flight range of 7 thousand to 10 thousand kilometers (in the 777-300ER version).

The flight deck is equipped with an Electronic Flight Bag (EFB) system. The EFB system data needed by pilots to control the aircraft has been converted into electronic form, making it easier to use.

In addition to the Electronic Flight Bag system, a number of solutions have been implemented on board the Boeing 777 aimed at improving passenger comfort. In particular, the cabin is equipped with a video system with screens mounted in the backs of the seats, and the seats in the business class cabin have reclining ergonomic backs.

The aircraft is equipped with the Matsushita System 3000i, which provides storage for more than 300 hours of video and audio recordings, played back upon passenger request.

An important advantage of the Boeing 777 compared to other modern airliners is the use of a variety of lightweight but strong alloys and composite materials in its design. The floor beams of the passenger cabin, aerodynamic fairings and other parts are made of composite materials. The total share of composite materials in the total weight of the entire aircraft structure is nine percent. Thus, the weight of the aircraft and the cost of its production are significantly reduced.

Boeing 777 airliners are part of the fleet largest airlines worldwide, including British Airways, Air France, Alitalia, Lauda Air and El Al.
