Yak-42 is a medium-hydraulic, narrow-body, three-line passenger aircraft developed in OKB A. S. Yakovlev in the mid-1970s for replacing technically obsolete IL-18 and Tu-134. The first Soviet passenger aircraft equipped with a high degree of dual-circuit vehicles.

The first flight of an experienced aircraft took place on March 7, 1975. In 1980, the aircraft was certified and enrolled.

In total, 183 different series and modifications of Yak-42: 11 were constructed at the Smolensk aircraft plant from 1977 to 1981, most of the side of 172 on the Saratov aircraft factory. In 2003, the production of Yak-42 aircraft was stopped. This aircraft could not be replaced by Tu-134, but to this day is in partial operation.

The location and numbering of places in the cabin, the planning scheme in the aircraft Yak-42. Best and Less Comfortable Places

There are two layout options Yak-42:

1. Single-class - economy class salon by 120 places;
2. Two-class - business and economy class salon per 100 seats.

The entrance to the aircraft is located in the tail. In addition to him, 6 emergency exits are provided. In both ends of the cabin placed Sanzuli.

Salon Scheme, Best and Less Comfortable PlanesYak-42 in a classroom layout for 120 seats

• Row 1. Quite good places. Pros: There are no passengers in front, so no one will open the back of the chair; There are a little extra bed space. Cons: Whole Flight Before the eyes of the partition, there is a toilet. Places "B" and "g" are located near the passage, so passengers going to the toilet may accidentally hurt sitting in these places.
• Row 6. Behind this row emergency exit, fenced by partition. It does not allow you to throw back the backs of the chairs, which can deliver some inconvenience.
• A number 7. Self best places. There is an emergency exit in front, so space is much more than on other rows. Here you can comfortably stretch your legs even with a high passenger. Ahead of the sitting passengers are fenced with a partition, so no one will open the back of the chair. The minus of these places is that there is no overview in the portholes (fully or partially)
• A number 13. Behind there is an emergency hatch, probably the backrest chairs are blocked
• It is possible that the backs of the chairs are blocked, because behind the emergency hatch is located ( this moment It should be clarified by representatives of the airline).
• A number 14. Good places For flight, since the backs of the previous row chairs are blocked and not folded.
• Row 19., places "B" and "G"located near the passage and toilets. Passing passengers can deliver inconvenience, it will also be possible to feel the smell from the toilet (but it depends on the quality of personnel work).
• A number 20. The worst places. The partition is located toilet, so the frequent movement of passengers, additional noise will not add comfort. In addition, the partition does not allow you to learn the back of the chair.

Business Class

• Almost all locations of the business class Comfortable due to a large number of space between armchairs and a wide passage.
• Row 1. Ahead is a partition separating the utility room and a toilet. Such a neighborhood can deliver inconvenience in terms of frequent movement of passengers and flight attendants.
• Row 4. Due to the partition, separating emergency exit and distinguishing salons, the backs of the chairs do not lean.

Best places in business class Yak-42

The most comfortable are the places 2a, 2g, 2a, 3G. They are located at the window and no one will interfere with the passenger.

Economy class

• A number 7.. Great places. A lot of place in front, so you can pull out the legs, no one will fold the back of the chair. Of the minuses it can be noted that the tickets for these places are quickly soldered and you can not put manual jack On the floor, due to the ahead of emergency exits.
• A number 13.The backs of the chairs are not regulated, but if the flight is not long, you can not pay attention to this.
• A number 14.Comfortable places, as ahead of the sitting passengers cannot learn the backs of the chairs.
• A number 20. Not comfortable places. The backs of the chairs are blocked. Behind is a toilet, which adds a bustle, noise, possibly a smell.

Flight and technical characteristics and features of the structure

Yak-42 is a all-metal lowlands with a half-flow fuselage (in width there is a similarity with the fuselage Tu-154), three turbojet two-circuit engines and a three-level retractable chassis. Console swelling wing and T-shaped tail plumage with a stabilizer of a suspended type. The fuel system consists of three tanks, one in the centroplane and two on the sides. Each of them holds more than six thousand kilograms of fuel and has a signaling of the reserve and the ability to combine fuel highways. Braking on the mileage is carried out by the brakes of wheels, spoilers and low seat, as well as the AN-24.

Yak-42d is an improved Yak-42 model. It has improved many operational characteristics: the flight distance by 25% increased, the maximum barometric height of the airfield was increased and the allowable side component of the wind on takeoff and landing was increased, reduced the permissible clutch coefficient with the WFP surface, the chassis brake wheels received fans that improved braking characteristics. The front entrance door was redone taking into account the standards of European telescopic galleries, which made an attractive aircraft for international transport. Increased in size (1700x850 mm) The left entrance door allows the use of telescopic lads, which reduces the time and facilitates landing and disembarking passengers in international Airports. To improve the comfort and safety of passengers, closed luggage shelves are installed on the plane.

The Yak-42D installed aerobatic and navigation and connected equipment, which allows flights along the CIS and Far Abroad tracks. The plane can also additionally installed equipment that allows flying to the European Region. To increase the regularity of flights to the Yak-42d, an automatic control system is installed, equipped with an automatic control of the engines and providing landing in meteo conditions corresponding to ICAO category (30x400 m).

• Yak-42 broke nine world records. The largest record was to overcome the air distance from Moscow to Khabarovsk without landing. Such a distance of Yak-42 was able to fly despite the fact that it is designed for small air routes.
• For Yak-42, a long take-off runway, such as for Boeing-737 and Airbus A319. It can be safely operated on airfields having short, up to 2,200 meters of WFP. To the honor of the creators of Yak-42, it must be said that abroad the machines with such flight weight on the runway of such dimensions are not allowed.
• Also for Yak-42 does not require an aerodrome ladder. Since the landing and disembarkation of passengers is carried out on the tail-ramp, which is simultaneously a hatch cap, which by its design resembles a freight ramp of transport aircraft.
• Yak-42 has high runway characteristics. So, for example, the speed of landing is 210 km / h. There is no other plane with such indicators, nor abroad. The smaller the landing speed, the greater the pilots of the time to think about the difficult situation.

The Yak-42 created in KB Yakovleva belongs to a number of world records in the class of similar machines. This achievement is amazing the fact that the Bureau did not specialize in the creation of passenger aircraft.

During one of the record flights, the car without landing overcame the distance from Moscow to Khabarovsk. The spread and development of the liner was first prevented by the problems of a structural nature, and then - the bankruptcy of the only factory.

History of creation

The development of the Middle Highway Linener Yak-42 started in the early 70s of the last century. The car was intended for replacement (with piston engines) and Tu-134.

For a new aircraft initially adopted a concept with three turbojet engines located in the tail part. Two units placed in the pylons, and the third was installed in the fuselage and equipped with an air intake derived in fortkil.

For this reason, the T-shaped scheme of the plumage was used, horizontal control surfaces were located at the top of the keel.

Several prototypes built in the mid-70s were distinguished by various swings and the presence of additional nodes (for example, parachute for output from the corkscrew).

According to the test results, approval received the third prototype, equipped with sweep tailpoint and enhanced main chassis racks with paired wheels. In this form, the Yak-42 aircraft was shown to the public during the airline in Le Bourget in 1977.

In the same year, the plane was hit in the same year, but the official commissioning and the exploitation of the liner on passenger flights took place only at the end of 1980.

Two years later, the Aircraft Yak-42 aircraft occurred on board 11040104 due to the defect design of the horizontal opament control system.

At the time of investigating the causes of the disaster and the development of a new node, production stopped.

Modernized aircraft began to be built only in 1984, and after four years, the production of an improved version of Yak-42d began, which allowed greater take-off weight and provided a greater range of flight.

The latest aircraft were collected in 2003. In total, 183 copies of Yak-42 and 42d were manufactured (the main production of cars was established at the Saratov Aviation Plant).

Design

When developing Yak-42, KB Yakovlev designers tried to combine the possibility of operation from unprepared runways, fuel efficiency and ability to maintain high cruising velocities.

To reduce the weight of the aircraft glider, monolithic channels of air intakes made of composite materials were applied. The plane of the wing was performed monolithic and did not have the lines of the connector, weighing the design.

On the aircraft Yak-42 uses the chassis with the nasal arrangement of the rotary front rack, which is produced over the flow of air. The main racks are available in the left and right side in the direction perpendicular to the stream.

Drives of chassis release and cleaning mechanisms, rotation of the front rack hydraulic. For fluid supply, the basic and emergency systems are installed.

System brakes are connected to the brakes of wheels equipped with disk mechanisms.

With a hydraulic system, a booster direction of the direction feeds from it. In case of refusal, the steering wheel is manually controlled. Aerons and heights are controlled from the effort of the hands of pilots.

Working pressure in hydraulic systems reaches 170 atm. H is created by two pumps installed on the distribution boxes of lateral engines. In case of refusal of the main pumps, the system is powered by two electrical stations - AC (from the on-board network of the Yak-42 aircraft) and permanent (from rechargeable batteries).

In addition to the chassis, the hydraulics are predicted, flaps, interceptor shields on the surface of the wing and stabilizer.

In the control of the stabilizer it is possible to use the emergency and the main system, each of which brings a separate screw drive assembly.

In normal mode, the deviation of the stabilizer of the Yak-42 aircraft is performed from the main system by rotating the worm mechanism screw.

In case of emergency situations, the stabilizer is controlled by turning the nut.

The primary electrical system of Yak-42 has three phases and an operating voltage of 112/208 volts (at a frequency of 400 Hz). Using transformers and rectifiers, the voltage is converted to an alternating current of 36 volts (400 Hz) and permanent 27 volts.

As sources of current, three generators with a capacity of 30 kW are used (installed on the TRD). There is also a 40 kW parking generator and two rechargeable batteries. If the main generators fails, it is possible to feed all consumers of the aircraft from batteries through voltage converters.

The stock of fuel on the Yak-42 aircraft is located in three tanks installed in the centerlane and on the sides of the fuselage. The tanks have the same container and contain 6170 kg of fuel. When 870 kg reserve, the backup residue is activated, and at 320 kg - alarm residue to the second round of care.

Each tank nourishes its engine with two pumps. For supplying auxiliary installation, a tank is used in the centerlane and a separate pump. In case of breakage of this pump, it is possible to power the installation from medium engine pumps.

In the emergency mode, the tanks are combined with the help of cranes that automatically open when the alarm system is triggered to the second round.

The truster turbojet engines D-36 developed in the Progress KB (Zaporizhia) are used as powerful installations. The engine has a weight of 1124 kg and is able to develop 6500 kgf extraordinct mode.

At the same time, the Yak-42 plane mode is able to take off on two engines. On cruising mode at an altitude of 8000 m, the traction is within the limits of 1600 kgf.

In the standard passenger compartment installed two rows of triple chairs. The first row of places in the plane has an increased space for the feet of passengers. For input and output, the door and sliding ladder is used, located in the tail of the fuselage.

The drive mechanisms of the route on the Yak-42 is made of an emergency hydraulic system. In case of occurrence emergency situations Passengers can leave Yak-42 through six emergency exits located on sides. At the beginning and end of the cabin are bathrooms.

In the cabin there is a partition installed between 6 and 7 rows of chairs.

Next to it are emergency exits. Because of this, passenger places 7 rows are always empty.

The second number of emergency windows is available between 13 and 14 rows. To ensure the unimpeded back of the back of the chairs of the thirteenth row are blocked.
There are options for the Yak-42 aircraft with a salon of 100 passengers with a division into a business class and economy class.

Business class locations are located in the middle of the partition. There are eight double chairs for passengers of this class. The rest repeats the standard interior scheme.

Features of operation

Yak-42 liners supplied for exports had a double cabin, which became a novelty to aircraft the USSR. Such a result was achieved by repeatedly inspection on the stands of all sorts of combinations of dashboard and remote controls and the selection of convenient combinations of automatic and manual drives.

When developing, designers have tried to provide the minimum scope of terrestrial maintenance and regulatory repairs, which should have reduced the downtime of the aircraft.

To download luggage and cargo, both standard containers and ordinary loading can be applied.

In order to simplify operation with flight fields of the 3rd class, an autonomous ladder applied to Yak-42.

The design of the Yak-42 engines does not have a reverse of thrust, but due to low planting velocity, the braking is performed by regular mechanisms of wheels and mechanization on the wing.

At least six airplanes are assigned their own names.

Mark on history

In the late 1980s, work began to create an upgraded Yak-42A based on the model 42d. The new aircraft was assumed to complete the extended fuselage and the cost-effective engines "Progress" D-36.

The first prototype was built at the end of 1992 and received the designation of Yak-142. It was planned to create a family of machines with passenger salons, designed to transport from 39 to 120 people.

Serial production was not expanded due to the bankruptcy of the Saratov Aviation Plant. A single serial aircraft is built, which is operated by LUKOIL airline.

In 1993, the Yak-242 aircraft was developed equipped with two PS-90A12 engines and using the Yak-42 glider elements.

According to mine technical characteristics He had to take an intermediate position between the near hospital and medium-hydraulic machines. The project was not implemented.

To date, the aircraft Yak-42 and 42d continue to be operated on the inner lines. At the same time, the operation of the part of the machines is suspended in accordance with the results of the accident investigation of the RA-42434 side.

Due to the bankruptcy of the Saratov aircraft factory (main manufacturer of cars), the support of the equipment is discontinued. Because of this, the further prospects of Yak-42 foggy, most likely, aircraft will be removed from operation and written off in the near future. As of March 20, 2015, only 38 cars remained in flight condition, and in August 2017 - only 35.

Video

In the mid-seventies in the Final Council Bureau. Yakovleva built a plane for medium length lines.

The Yak-42 passenger aircraft became the first in the Soviet Union by an aircraft, which was installed three turboctive dual-circuit (degree 5.4) of the engine. Since the beginning of the eighties, a serial release was made, which ended in 2003. For 23 years, 183 cars are launched in the sky.

AirChanges who received the order of the USSR government applied technologies worked out when creating the previous version of Yak-40. However, innovations were applied, changes were made to the wing design. This made it possible to improve aerodynamics, speed, handling.

Four prototypes were built in two years, the wing of the first prototype almost repeated the configuration of the Wing of Yak-40, had a small sweatshirt (11 degrees). In 1975, the plane made a debut departure, but showed not too good speed indicators. It was decided to increase stepmithium to 23 degrees to improve speed parameters.

After making the adjustment to the design, tests continued in the sky. Test pilots noted that the aircraft managed well, it is stable and speed.

At the Paris Aviation Salon, Yak-42 flew in 1977, where he successfully demonstrated its qualities. Certified in 1980. The plane awaited not the easiest fate: an accident in 1982, then stop the release and restriction of flights. In 1990, the USSR broke up, the crisis began, the procurement began sharply, the market was empty. In 2011, after the catastrophe in Yaroslavl, all flights of aircraft of this brand were stopped.

Modification Yak-42d

1988 was marked by the appearance of a new version having increased running weight and range (on a quarter), flight height. The Yak-42d aircraft could take off and sit on highly located and hard-to-reach airfields, adapted under the conditions of hot climate.

The machine with the best characteristics was supplied to the overseas market. Pre-consistent certification for European standards: satellite navigation equipment, collision warning systems in the air and earth, installed radio station. Requirements for noise reduction were performed.

In the layout of the passenger salon, it is easy to make changes: from installing more than 120 chairs, before re-equipment in the cargo version.

Currently, high-quality cabins for business transportation and charter flights were individually carried out and constructed.

Flight Specifications:

• Airplane Length - 36.38 meters
• Machine height - 9.83 meters
• Wing span - 34.88 meters
• Mass of an empty aircraft - 34.6 tons
• Run weight - 56.5 tons
• Fuel capacity - 18.5 tons
• Motors - D-36, three turbofan with 6475 kgf
• Maximum speed - 810 km / h
• Speeding speed at the height - 750 km / h
• Range - 4 thousand kilometers
• Height - 9600 meters
• Pilots - 2.
• Passenger capacity - 120 people in an economic version, up to 50 passengers in a business layout

Design features

Aerodynamically Yak-42 is a low-depth, has three reliable engine D-36, a three-voice chassis.

Passengers enter the salon and leave it through the ladder in the tail. It may be serviced by the flight of this aircraft on unpreparedly traditional airfields, they are economical and maneuverable.

Power plants have fuel efficiency, reduced noise level and harmful exhaust to the atmosphere that comply with international certification requirements. Powerful engines will continue to fly when one of them fails, thanks to good traction.

The hydraulic system allows you to remove the chassis and brake, and the wheels are universal (similar to the wheels of Tu-154). Kerosene is located in three tanks that eat a separate engine. The plane is adapted to take off and landing with shortwood.

Details also worked in the cabin. For that time, the aircraft could boast a comfortable lounge with good sound insulation. The portholes in the cabin cabin round and large. Luggage shelves are made closed, for passenger safety.

Nowadays, the operated aircraft Yak-42d have two layouts: classmate and two classes of comfort.

The entrance to board is carried out through the tail hole, there are six spare outlets in case of an emergency.

In the cabin there are two bathrooms, at the beginning and end. The chair has 2/2 chairs, they are wider than in economy class. Two rows, eight places are available in the salon of high comfort.

The economic class (96 seats) looks like this: 3/3. The best places are located in 1, 3 and 10 row. Before the first there is no chairs ahead, here more places For legs, and ahead is partition.

The third and tenth row stand right behind the spare outputs and more space before them. Under their seats are forbidden to place luggage, and tickets for these places will not be sold to foreigners, disabled people, passengers with children and older people.

In 2 and 9 row of the back chairs are limited in folding or blocked, because there are emergency doors from behind.

The worst places will be chairs in 16 row, the toilet is behind it, and the backs are fixed in the same position.

Modern operation

To this day, Yak-42 in different versions is operated in Cuba, in Pakistan, Iran, China, in Russia, CIS countries and former European countries.

Izhavia (Izhevsk) has 9 Yak-42 / Yak-42D aircraft in his fleet. The last board was obtained in 2017, it raises 17 thousand hours (with a limit of 40,000 hours). Flights are carried out within the country by numerous routes. The aircraft delivered to the Izhevian company, decorated in a new way: comfort in the bathrooms, modern cabin upholstery.

Airline Izhavia in the summer of 2018 begins regular post from Chelyabinsk airport in Sochi and Anapa. Twice a week, the Yak-42D aircraft will serve flights. The provided board is comfortable and modern. Ticket sales are already underway.

Designed for small and medium-range flights, Yak-42 was developed in the Soviet Union in the 1970s in KB Yakovlev, to replace outdated IL-18 and Tu-134. The plane has three turbofan engines located in the tail of the fuselage and fortkill. It is able to take off and sit on the weakly prepared airfields with short runways, has high fuel efficiency, has the reliability of engines and maintenance systems.

General information about the aircraft Yak-42

The flight tests were held in 1975, and in 1977, Yak-42 was first presented at the exhibition in France. From 1980, the plane entered the Aeroflot.

For two years of operation on domestic yak-42, one and a half million people were transported, the plane was used on large quantities routes both within the country and on international destinations.

The model with an increased range of Yak-42 D (see photo) enrolled in mass production in 1988

The fate of the aircraft, despite its effectiveness, did not work out. Perestroika and disintegration of the union, reducing the passenger transportation, the diversity of attractive foreign models was not played in favor of the domestic small Yak-42. After the closure of the Saratov Aviation Plant in 2003, the serial production of the aircraft was discontinued.

For 2018 in operation russian air carriers There are 35 yak-42. 2 more - in China, 8 - in North Korea and 4 - in Cuba. Several aircraft are in leasing in Pakistan and Iran.

Flight Specifications

Salon Salon Yak-42 per one service class

Instruction currently, Yak-42 and Yak-42 D have two types of interior layouts: on one and two classes. We will get acquainted with the configuration of the salon of the same class on 120 passengers and we define the best and worst places (see the scheme).

The entrance to the plane is located in the tail part, except for it there are 6 emergency exits.

At the beginning and at the end of the cabin there are two toilets (see the Salon scheme).

1 row - enlarged foot space. Comfortable places With a slight disadvantage because of the proximity of the toilet.

For 6, there is a partition, and immediately behind it - two emergency exit. The backrest seats of the sixth row are deflected on a small angle.

Before 7, there is a large space for free access to the spare doors. Under the seats it is impossible to put baggage. Places near spare outputs are not provided:

• Children under 12 years;
• disabled;
• passengers carrying animals;
• Foreign citizens who do not speak Russian or English.

Two more emergency exits are between 13 and 14 rows. The backs of the chairs in the 13 row are fixed.

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

Best places

For a comfortable flight, it is very important to sit relaxing. This can be done, stretching the legs and throwing the back of the chair. Best places in Yak-42:

• 1, 7 and 14 - completely

Worst places

The worst can be called places in the tail of the aircraft, the place next to the bathrooms and those that the back is not laid out. In Yak-42, this is:

• 6, 13 and 20 - completely

These places have the backs of chairs do not lean.

19 C, D - Places in the passage next to the bathrooms

Places 20 of the last row are uncomfortable. They have fixed backs, for them are toilets and they are located in the tail of the aircraft. Noise of engines are also heard here.

Space Salon Yak-42 into two class of service

In Yak-42, there is a layout of 100 passengers in the cabin into two classes. The business class takes the space of the first six rows (see the scheme). Only 16 seats.

Otherwise, the configuration and the choice of the best places are the same as in the Salon of Yak-42 by 120 passengers. (Starting with 7 rows of schemes coincide)

According to the reviews of passengers, Yak-42 as a whole, like travelers. Landing outwardly by foreign liners, our domestic "yashka" is not inferior to them in reliability, capacity and sustainability. This small plane takes off quickly, flies very smoothly, quickly sits down. The noise in the nose is very small, and in the tail no more than in airbuses and boings, but for some reviews even less. When you go on the salon, does not pump and does not shake. He does not need a long landing band and it stops quickly after landing.

In the time of the USSR, many excellent aircraft were developed and with the possibility of the development of domestic aircraft and investment, Yak-42 with further improvement could take the honorable place in a number of modern commercial liners.

The operation of the Yak-42 aircraft began in 1980. Purchased liner for passenger traffic On the nearmumps. In 1988, the production of its improved version of Yak-42d began. This liner differed a greater range of flight and high weight.

Serial production of both versions continued until 2002. A total of 194 aircraft were built, including 64 Yak-42 and 130 yak-42d.

As of 2017, Yak-42 aircraft continue to be operated. There are such liners in the parks of many Russian companies. Although the main transportation is carried out by foreign aircraft, Yak-42 continues to show its reliability, convenience in operation.

The presence of its own ladder, which is in the tail of the aircraft, makes it possible, without waiting for the supply of the trapping machine, put the landing and disembarking of passengers, which is quite convenient. Since they do not need to wait, sometimes ten and even more than a minute.

Amenities that are offered passengers are large round portholes. There is a good sound insulation in the cabin. Configuration of chairs 3 + 3.

Salon and best places

The entrance to the cabin is located in the tail of the aircraft. There are 6 emergency hatches in the plane. In the nose and in the tail parts of the cabin are toilets. The layout of the cabin has two options. With the first - this is a business class and economy class, with a second-class layout, there is only an economy class.

With a single layout of the salon in the first row of the place are recognized as good, but having some drawbacks. Among the advantages absence of seats ahead. This means that no one will throw back the back, the stainlessness of the passenger. Positive is an enlarged foot space. True, to pull them out far from everyone. The partition is located close.

The disadvantage is too close to the toilet. Especially because of this, inconvenient passengers in the field "B" and "g". They border the passage. Here it is possible to contact with passengers moving along the passage. Sometimes, during the flight, turns to the toilet accumulate. At the first row they accumulate most often. It should also be noted a partition located in front. Look at her during the whole flight is not particularly nice.

The following rows, up to the 6th, standard. There are, of course, in the chairs that are in them, their pros and cons, but they are not particularly significant.

Not the best places are in the 6th row. The main minus - the backs of the chairs do not lean. This is done due to the fact that there is an emergency exit.

The best places are armchairs in the 7th row. Since before this, there is an emergency outlet, a large empty space allows you to stretch with all the amenities of a person of any growth. Another plus - as before the chair, which is far away, no one will prevent the seated back of the back.

There are also cons. But they do not relate to comfort. So, here it is impossible to put a manual stall on the floor. More minus is an almost complete absence of a review in the porthole. You can also call a minus and the fact that in this row is not allowed to be some categories of passengers. These are pregnant women, elderly, passengers with children, children, foreign citizens, poorly knowledgeable Russian or English.

The following 5 rows are standard places. There are no serious advantages about some serious advantages and minuses.

The chairs of the 13th row blocked backs. This is inconvenience, as passengers cannot lean them, and are forced throughout the flight to be in the same position. Cause - behind the emergency exit.

In the 14th row are places comfortable for flight. This is the presence of a large footpace, and the fact that ahead of the seated passenger will not fold the back of his cress and will not create inconvenience.

Places in the ranks from the 15th to 18 are difficult to highlight, both in good and in having disadvantages. They are standard.

In a number of 19th, the place "B" and "g" have drawbacks. They are at the passage. Since the toilet is located near, here during the flight the intensity of the movement of passengers is large.

The worst places in the Salon Yak-42 are recognized in the 20th row. The backs of the chairs are locked here. Behind is the partition. It is located toilet. At the same time it is so close that the passengers are well audible sounds of a drain barrel.

Yak-42 aircraft, inferior to foreign analogues appearance, wins them in reliability

Yak-42 airliner can take on board 120 passengers. In the cabin they will have the level of comfort, sufficient for several hours of flight. During this time, the liner transports them by almost 2 thousand kilometers.

A distinctive feature of the liner - he takes off pretty quickly. Flying it passes exactly. Quickly occurs and landing. In the nose part of the cabin, noise from working engines is almost not heard. In the tail part it is present. But its level is completely insignificant. It has been established that noise in the tail part is less than in the salons of the Boeing and Airbus.

Another positive feature of the aircraft. He does not need extended runways. After landing, Yak-42 stops very quickly, surpassing such foreign aircraft.
