Description of the instrument panel of the ssj 100 aircraft. Cabin features and amenities

During the 12th International Aviation and Space Salon MAKS-2015 United Aircraft Corporation - UAC invited bloggers to visit, who were able to get acquainted with some of the aircraft that are part of the corporation. I would like to tell you about the plane Superjet 100. This was my first encounter with this car. The first time I boarded this plane was just a day early. And today I was given a full tour of this aircraft.
1.

We visited the plane SSJ 100-95LR(RA-89034), intended for Yamal Airlines. This is a short-haul passenger aircraft with a normal aerodynamic design with a low-swept wing and a single-fin tail. It is intended for regional aviation. The first regional jet aircraft was the domestic Yak-40, which was also supplied for export. Previously, regional transportation was carried out either on Boeing 737 aircraft, which are expensive for such transportation, or on turboprop aircraft. In the late 1980s, Bombardier turned its large business jet, the Challenger, into a regional jet, the CRJ. It first flew on May 10, 1991, becoming the first modern 50-seater regional aircraft. Then came the Embraer planes. They are larger in passenger compartment dimensions than the CRJ. However, the Sukhoi Civil Aircraft company (SJSC GSS) has created a regional aircraft with passenger cabin characteristics similar to airliners designed for “hub to hub” flights, that is, between major cities. This condition allows airlines to attract additional passengers on their flights.
2.

The excursion was conducted by Alexander Viktorovich Dolotovsky, deputy chief designer of JSC GSS for aerodynamics.
4.

The aircraft is configured to carry 103 passengers in a full economy class cabin. The seats are installed in a 2+3 configuration. Seat width 465 mm.
5.

The first three rows of seats are installed with an increased pitch of 33 inches. They are separated from the rest of the cabin by an optional curtain, which serves as a class separator. The measure allows airlines to sell the first three rows as business class. This approach is often used in various airlines, when passengers are provided with not much more comfort on the plane, but are given business service, which consists not so much of seats, but of the speed of passage through airport terminals, baggage claim, and so on. For example, the airline Lufthansa uses this. Also, the size of the fuselage of a Superjet allows, if necessary, to install a full-fledged business class seat in the bow, the size of which is not inferior to those found in the A320 or Boeing 737 aircraft. This is exactly the layout that Superjet aircraft of Aeroflot airline have.
6.

Next are the chairs with 30-inch pitches. The space for passengers here is provided not only by the step, but also by the size of the seats themselves. Even though these are not the slim seats that are now available and are half as thick, these seats are thinner than those that fly on airplanes produced in the 90s. So even with a 30-inch pitch, occupants feel the same as with standard 31- or 32-inch pitch configurations.
7.

The luggage racks in the passenger cabin have been selected in such a way that passengers who have previously traveled on a wide-body aircraft will not have difficulty with their hand luggage. The luggage compartment located above the long row (right) is slightly larger than what the A320 provides in its standard configuration. The shelves opposite (on the left) are smaller in depth, but a standard suitcase will still fit into it. And considering that this shelf stands above the two-chair unit, there is enough space for everyone. That is, the volume of the luggage compartment per passenger here does not depend on which side he is flying from. Moreover, if we compare the size of the shelf with the direct competitor of the Superjet - Embraer 190, the height of the shelf of our aircraft is almost twice as large as that of Embraer.
8.

The wide aisle between the seats was chosen for reasons aviation security: width of Trolley (food cart) + 1 passenger. This is due to the absence of emergency exits to the wing on the plane. This decision was made initially. The presence of emergency exits to the wing limits designers when creating the cabin layout. In the area of the wing exits, there should always be an increased seat pitch. Plus, a row of chairs with non-reclining backs may appear in the exit area. Wherein aviation regulations When an aircraft is configured with up to 110 seats, it is allowed not to make emergency exits to the wing if, during special tests for emergency evacuation, passengers fall within the limits of special standards. This is about 90 seconds. Thanks to the wide passage, the tests were completed without injuries, and all standards were met. The aisle width on the Superjet is 510 mm, and the cabin height is 2.13 m.
9.

The rear toilet is specially made large. It is equipped with a changing table. This is convenient for passengers traveling with small children. In addition, the size of the toilet is convenient for people with disabilities. There is also a changing table in the forward toilet. I was surprised by the presence of an ashtray in the door. It turned out that this is a container for small garbage, which is labeled as an ashtray by default. Therefore, if you need to spit out the gum, you don’t need to glue it to the chair. Airlines spend a lot of money cleaning them. Walk to the toilet and put it in the container.

An ATLAS standard kitchen is installed in the aft service area. It consists of modules and on this particular aircraft it is equipped with one oven, boiler and coffee maker. It also comes with three full-size food carts. Optionally, there can be a large kitchen with four ovens, in which there will be six carts. This is necessary for airlines that plan to transport passengers long distances and provide hot meals. The galley in the bow is equipped with half-size food carts rather than full-size ones. Optionally, a full-size kitchen with two ovens can stand in its place. The photo shows the aft kitchen food carts.
10.

All interior lighting is LED. There is not a single incandescent lamp here. LED lamps are much more durable. This reduces the cost of aircraft maintenance.

Regarding individual airflow nozzles. They are installed on older planes because the air conditioning system does a poor job of equalizing the temperature throughout the cabin. The Superjet aircraft has a modern digitally controlled air conditioning system. Therefore, individual airflow nozzles are not needed here. They are optionally installed at the request of airlines. But the plane is very comfortable with the air conditioning system working.
11.

The windows installed on the aircraft are the largest not only in the class of regional, but also narrow-body aircraft. The line of windows is located in such a way that it is convenient for passengers to look at the ground. The designers proceeded from the fact that in flight it is more interesting to look at what is happening below you.
12.

Why such a comfortable interior? This aircraft is designed to be operated under a “Hub and Spoke” system. These are flights between major cities (so-called “hubs”), and then on regional planes to individual regions. “Hubs” are storage areas, and regional airports are distributors of passenger flow. Today, a regional jet is usually a fairly serious compromise in terms of passenger comfort. For example, if along the route from major airport CRJ plane flies to the region, you will have to give your hand luggage in luggage because it won't fit in the shelves. In Europe, such aircraft are beginning to be squeezed out of the market by high-speed railways. People really don't want to embarrass themselves. Therefore, when forming the technical specifications for the Superjet aircraft, a lot of work was done with marketing specialists. The goal was to provide passengers with the same level of comfort as on narrow-body aircraft and wide-body aircraft in economy class. So that passengers do not feel any damage to their comfort. So that they do not have to check in their hand luggage as checked luggage, thereby increasing the speed of aircraft turnover at the airport. Therefore, today the Superjet 100 is new standard comfort for regional transportation.
13.

The large cross-section of the fuselage clearly dictated very stringent requirements for the level of aerodynamic perfection of the layout. Because the larger the fuselage, the worse the aerodynamic quality of the aircraft. Comfort is bad for aerodynamic efficiency. Therefore, in order not to waste more fuel than competitors, the designers went for an unprecedentedly large wing extension. The aspect ratio of a wing is the ratio of the square of its span to its area. Today this is one of the few passenger aircraft with a metal wing with an extension of 10. There are no winglets on the wing. They are installed when it is impossible to make a high aspect ratio wing. Although this idea is being considered and, perhaps, winglets will still appear on Superjets.
14.

The wing is formed from supercritical airfoils. When an airplane flies at transonic speeds (more than Mach 0.75), it comes close to the sound barrier. In this case, on the upper surface of the wing the air flow speed becomes supersonic. The appearance of supersonic zones leads to the appearance of wave drag, which can increase the aircraft's drag by 30%. If we take a standard profile, then at speeds of Mach 0.72 it will push very hard and the plane simply cannot be accelerated further. They have been struggling with this problem for a long time. There are different ways. The simplest is to reduce the thickness of the wing profile. Therefore, on all fighter aircraft the wings are very thin and flat. On all old transonic aircraft the wings are also very thin. But such a wing is very heavy and it is difficult to fit fuel into it. Back in the 60s, the so-called supercritical profile was invented. But not everyone knows how to do it well. From the very beginning, the creators of the Superjet worked closely with industry institutions. And when the question arose about wing profiling, they turned to TsAGI. As a result, the wing turned out to be high-speed. The aircraft was optimized to fly at a mach of 0.78. In reality, he flies at a swing of 0.79. As a result of the fact that the designers made such a good wing, the Superjet 100 with a large fuselage is more fuel efficient than the Embraer 190 with a small fuselage by about 7%.
15.

We arrived at the cabin. During its design, a lot of changes were introduced based on the results of communication with airlines about what a passenger aircraft should look like. One of the important changes is the switch to an Airbus concept cabin, rather than the Boeing concept cabin that was originally envisioned. Airlines have made their assumptions quite clear that Airbus concepts are the future. As a result, the aircraft has a side-stick cockpit and a highly automated control system in both manual and automatic mode.

In the basic configuration, two FMS (Flight Management Systems) are installed in the cockpit. This is a computer flight control system that includes an on-board sensor, a receiver and a computer with navigation and data bases. flight performance aircraft. The aircraft is capable of automatic flight immediately after takeoff, since the FMS provides not only horizontal but also vertical navigation. The aircraft is certified and performs automatic approaches in the 1st, 2nd and 3rd categories, including automatic landing.
20.

The aircraft is approved for flights in the precision area navigation zone - P-RNAV (Precision Area Navigation). Area navigation RNAV is a navigation method that allows aircraft fly along any desired trajectory. This is the first Russian aircraft to have such a certificate. At the same time, the certificate was issued based on the results of tests that were carried out in Finland under the close attention of Eurocontrol.
21.

The aircraft can perform approaches in vertical navigation mode, when a three-dimensional trajectory of space is formed by the Flight Management System using navigation tools that are on board. These are two sources of satellite navigation: GPS and GLONASS. Three inertial systems with high resolution- IRS (Inertial Reference System). All radio navigation aids: VOR (Very high frequency Omni directional radio Range), DME (Distance Measuring Equipment). In addition, an automatic radio compass - ADF (Automatic Directional Finder) - can be optionally installed on board. This is an automatic direction indicator that allows for approaches in northern regions. In particular, aircraft with two optional ADFs are supplied to Yakutia Airlines.
22.

23.

The aircraft is certified for operation in the temperature range from -55° to +45°. Traditionally, low temperature tests are carried out in Yakutia with the aircraft completely frozen. During the tests, testers showed the possibility of operating the aircraft without hangars in conditions of average temperatures below -45°.

This machine has an optional weather radar with wind shear detection system. Plus, this radar has mapping and turbulence detection capabilities.
24.

A little about the control system. Taking the Airbus cockpit concept as a basis, the designers did not engage in simple copying. Together with TsAGI, completely unique control laws were developed, which were completely written here in Russia with the active participation of the 15th TsAGI department - the department of stability and controllability. These laws include not only those features that are already implemented in Airbus, but also a number of those that are just now appearing on the A350. The plane featured a certain mix between the Airbus ideology and a traditional aircraft. The fundamental differences are that the level of automation here is the same as on Airbus, but at the same time, for the automatic thrust control function, the Superjet has an automatic thrust control with actuators. That is, when the autothrottle is operating, the engine control handles (throttles) move, which is not the case on Airbus, where the throttles are in the “Climb” position the entire flight. If pilots forget to remove the throttles during landing, a sudden increase in thrust begins for them. For this reason, there was at least one A320 crash in Sao Paulo on July 18, 2007. In addition, the Superjet, from the point of view of flight characteristics, behaves like a conventional aircraft with a mechanical control system. The Airbus has major differences in its behavior in both the longitudinal and lateral channels from mechanically controlled aircraft. This is the developer's decision. But the Superjet designers decided that this idea was not a very good one. Because a pilot begins his training on an airplane with a mechanical control system. He develops certain skills. In order to ensure that, if a pilot finds himself in a stressful situation, he does not receive additional factors that result in the aircraft’s behavior not meeting his expectations, the designers made the aircraft’s dynamics in such a way that pilots would not feel any difference when switching from an aircraft with a mechanical control system to a Superjet. This introduction is very good feedback, both from Russian pilots and from foreign ones, starting from Airbus pilots. Philippe Castaing, who is currently involved in testing the A350 aircraft, worked for 6 years on the EASA (European Aviation Safety Agency) team to certify the Superjet aircraft. He really likes this car.

Glass in the cockpit provides maximum viewing angle for the pilot civil aircraft. This is important for regional aviation. Because you have to fly to bad airfields in poor visibility conditions. The glass is heated and, at the same time, it is absolutely transparent. The technology was developed specifically for the Superjet. Now the Sully-Gobaine company (France) is the only manufacturer in the world that can produce heated glass of such an area and such a level of transparency.

After getting acquainted with the cockpit and passenger compartment, we went down the stairs and walked around the plane.

All aircraft design was carried out digitally from the very beginning using the CATIA V5 3D modeling system. This made it possible to analyze various compartments in 3D. In addition, the experience of the team that had previously worked in different time with different planes. Thanks to this, the smallest details were worked out. For example, the fuel refueling control panel hatch, which is always accessible. The plane is made to be very short term turnover Time on the ground should not exceed 30 minutes. At this rate, it happens that people forget to close the hatches. To prevent it from being torn off in flight, the hinges are made in such a way that it is closed by the incoming air flow.
29.

There is not a single analogue system on the plane. All systems are digitally controlled. The fuel system is also digital. It has its own fuel density meters, which are located in the tanks and provide measurement of fuel density. Therefore, fuel is taken on board not in liters, but in kilograms. The measurement is carried out with high accuracy. Thus, the crew always knows the exact amount of fuel in kilograms, regardless of whether the fuel was brought to them cold or hot. This is both savings and safety. IN fuel system there are free water sensors. They are designed to detect water in fuel. Traditionally, this procedure is done as follows: samples are drained from the drainage of fuel tanks, into which potassium permanganate is poured. In this way, the presence of water in the aircraft tanks is checked. If the car flies with the frequency with which a regional jet flies, and the Superjet makes 3-4 return flights a day (that is, 6-8 takeoffs and landings), you may not even notice. Therefore, the fuel system contains sensors for detecting free water, which will light a lamp during the refueling process when it is detected.
30.

The main landing gear of the aircraft is made according to a two-strut design. Typically this design is used on large wide-body aircraft. It is significantly superior to a single-strut aircraft both in terms of strength against a side impact (when landing with a side wind) and in weight. Despite the fact that the stand itself is heavier, its weight with the entire surrounding structure is lighter.

This is a new generation of regional engines. The most modern technologies were used in its design. First of all, this is 3D optimization of all aerodynamic surfaces. Since it is intended for regional jet, great attention was paid to the entry of foreign objects into it. All fan blades can be changed without removing the engine from the wing. The engine is built using a modular architecture. This allows most repair work to be carried out without removing the engine. If there is still a need to replace the engine, it is changed in 1.5 hours by a team of 2 people.
38.

On a Superjet plane it is not only convenient passenger compartment, but also the luggage compartment. Let's compare it to the luggage compartment of an Embraer 190 aircraft, whose height is less than one meter. Since luggage on both planes is loaded in bulk, in order to load/unload the flight, it is necessary to place a person there. On the Superjet plane, the height of the luggage compartment was specially chosen to be more than 1 meter. This allows loaders to work in more comfortable conditions. In addition, despite the fact that the Superzhedt is larger than the Embraer 190, the height of the lower edge of the luggage hatch is lower. For the Embraer 190, this height is more than 2 meters. That is, standing on the ground, it is very difficult to reach the hatch opening handle without rolling up a stepladder. To load luggage on board last passenger, who has just arrived, you need to roll a stepladder up to the Embraer 190. On a Superjet aircraft, the hatch can be opened from the ground without the use of additional devices.

Today, there is a serious need in the world for a 100-seat narrow-body aircraft, which will allow airlines to manage their costs in times of crisis. And the Superjet 100 fits this role very well. That is why the GSS company operates in all regions of the world.
41.

Additional information on the number of aircraft and their delivery times can be found here.
The percentage of the share of Russian and imported parts in the Superjet design is very well written in this article.
As for production under sanctions, it is difficult to get a clear answer to this question. Nobody knows what will happen tomorrow. And one can only guess about it.

Many thanks to Alexander Viktorovich Dolotovsky for the excursion. And also to the United Aircraft Corporation for the invitation.

Report by Igor Kudryavin from the cockpit of an SSJ100

Did you have a dream as a child? Personally, I dreamed of being a pilot, a pilot specifically civil aviation, and even more specifically, I dreamed of flying a Yak-40 aircraft. I had his models, photographs from magazines, pictures, I found out where the pilot school was located and they sent me documents for admission, but fate made me an air defense officer. I was able to fly on airplanes more than once, but only as a passenger, for whom the cockpit was a restricted area. But yesterday I was lucky, I visited the holy of holies of the Russian aviation industry: KnaF ZAO "GSS", this is the same glorious place where the SSJ100 civil aircraft is assembled. I visited a place I never even dreamed of visiting: THE PILOTS COCKPIT!

I saw a lot more, for example, what an engine looks like without casing and many other interesting things.

The heart of the plane

There are things that you look at and understand that there is no limit to admiration for human engineering. Such man-made masterpieces can easily include an airplane engine. He is beautiful! Moreover, when the engine was produced in your homeland, like the plane itself

Beautiful? Do you know what exactly is involved in metal protection? So know this:

This is the front view

It's behind

There is a myth that the engine for the Sukhoi SSJ100 aircraft is imported, which is not true. This engine was designed and assembled at our Russian enterprise, in cooperation with the French, while 2/3 of its components are manufactured in Russia.

If you are planning a short-haul flight, there is a chance that a Sukhoi Superjet 100 will be served on the ramp: the cabin layout and the best seats are presented below. The airliner with the certification name RRJ was developed by Russian aviators with the participation of foreign companies. It became the first product of the domestic aviation industry whose noise characteristics received good marks when tested for compliance with European standards.

Model features

Superjet is designed according to classical aerodynamic design: the liner has horizontal tail(stabilizer) located after the wing. The design is common in military and civil aviation, as it ensures flight safety and optimizes takeoff performance.

The model is equipped with SaM146-1S18 engines: they are produced at a Franco-Russian plant. The option made it possible to increase the range of flights, passenger capacity and take-off weight (the indicator at which a ship can take off while complying with safety rules).

Another feature of the Sukhoi Superjet is the use of composite materials to reduce the weight of the aircraft. In the future, designers plan to increase their share, but the process is slowing down due to additional research. Representatives of JSC Sukhoi Civil Developments emphasize that they are going to study the impact of sudden temperature changes on materials.

As for the cockpit, it is equipped not with standard steering wheels, but with sidestick joysticks. This made it possible to free up space for a convenient and ergonomic arrangement of other devices, as well as improve visibility of the panel. To ensure effective operation of the sidesticks, the Fly-by-wire system has been introduced: the movements of the joysticks are transmitted by electrical signals.

Development history

After the collapse of the USSR, the production of airliners stopped, and airlines used aircraft, released earlier. But in the 2000s. the resource turned out to be exhausted, so the state announced a competition: projects of new models were presented at it.

The future version of the Sukhoi Superjet won, and after 3 years the designers began the 1st assembly. The model was put into operation in 2011 on flights of the Armenian carrier. Now Aeroflot has become the main operator.

Aircraft modifications

In addition to the basic modification, the following options have been developed:

Sukhoi Superjet 100B-VIP is an administrative and business version of the aircraft. It combines the comfort and versatility of airliners designed to transport officials with the reliability of designs for scheduled airlines.
Sukhoi Superjet 100LR (SSJ100 LR) is designed for short- and medium-haul flights. The modifications, which at one time became revolutionary for the Russian Federation, made it possible to increase the range by 1,400 km. Based on this version, the Sukhoi Superjet 100LR-VIP model was also released.
Sukhoi Business Jet is produced according to individual orders. The model is operated by the Border Service of Kazakhstan.

All models have received international certificates, so they can also be used by foreign carriers.

What projects are in development

The designers expect to implement the following projects:

The Sukhoi Superjet 100SV is planned for production in 2019, and it will be able to make its first flight in 2020. The capacity is going to be increased to 125 passengers.
Sportjet by Sukhoi will be designed to transport athletes.
Suhkoi Superjet 75, designed for 75 passengers, will be operated on routes up to 2 thousand km long. The developers hope that it will allow companies to reach a new business segment.
Sukhoi Superjet 100R will include an increased share of Russian components.

As for the results of the already created models, in 2018 it turned out that their flight hours on Russian airlines decreased. But for foreign companies the indicator increased, and there were no complaints about profits. This is due to the fact that Russian carriers are having problems with the supply of components. To correct the situation, a set of measures was introduced to increase flying hours: it is too early to assess its effectiveness.

Specifications

Which companies operate it: present and prospects

As for the operation of the Sukhoi Superjet 100 aircraft, reviews from companies are positive. The liners are used by the following carriers:

There are also models in the air fleets of Armenia, Laos, Mexico, Indonesia and Switzerland. The manufacturer plans to expand cooperation with companies operating in Ireland and Italy. There is also the possibility of concluding contracts with Asian carriers.

How to choose the best seats: interior layout

For those wishing to board the Sukhoi Superjet 100, the cabin diagram will help them find the best options. The standard seating arrangement, designed to carry 87 passengers, is used by both Aeroflot and foreign enterprises.

Business class features

The seats in this class of service on the Superjet 100 are comfortable. They are arranged in 3 rows according to a 2-2 pattern. True, passengers seated in the first row will have less legroom due to the partition; You won't be able to put things on the floor either. There is also a toilet nearby, which can be a nuisance. But in any case, you will be more comfortable than in economy class.

Having extra space will allow you to stretch your legs.

The best options in the business compartment are the 2nd and 3rd rows. The legroom here is 1.5 times more than in the budget part of the cabin. In the 3rd row, noise can be heard from the "economy" mode, since the partition is quite thin.

Economy class cabin

As for the location of economy seats on the Superjet 100, they occupy rows 6 to 20. The seats are placed according to a 2-3 pattern, with seats E considered the worst option: they are located far from the porthole, which does not allow you to enjoy the views, and from the aisle. But, if you often get up to go to the toilet, then the option will be more convenient than choosing a seat by the window. After all, you only have to bother one neighbor!

The design of the cabin does not imply the presence of seats near emergency exits, so the Space + category is represented only by the 6th row.

When choosing, consider the following:

Best places are in the 6th row as you will get more legroom. There are no seats in front, and you won’t encounter a situation where your neighbor reclines his back, preventing you from sitting comfortably with your laptop. But the width of the seat will be slightly smaller, since the pull-out tables are mounted on the armrests. The latter do not fold completely, which can cause inconvenience. The disadvantages include the fact that this row is occupied by passengers with small children. Also, companies charge an additional fee for reserving seats in the 6th row, since they are classified as Space +.
Seat 6D has the added disadvantage of bumping into the seat for business class passengers who decide to use the rear toilet.
In rows 7-19 there are standard options: there is not much legroom, but you will not feel much discomfort.
Traveling in row 20 will not be a pleasant experience. The backs of the seats do not recline, so sleeping will be difficult. The proximity of the toilet, where other passengers constantly look, also plays a role. It's a little more comfortable in seats 20A and 20F, located near the windows: you won't be disturbed by people scurrying along the aisle. The worst options are 20C, 20D and 20E.

Choose places by checking the map and make your trip comfortable. And a photo of the interior of the Sukhoi Superjet 100 will help you finally get your bearings (click to enlarge).

The open architecture of the avionics complex was designed by THALES based on integrated modular technology. This made it possible to reduce the number of structural units of the complex by approximately 15% and thereby simplify its maintenance. To simplify maintenance of the aircraft as a whole, an on-board maintenance system is provided that is capable of detecting failures down to a structural unit in all major aircraft systems. At the same time, the basic avionics configuration is more functional compared to its closest competitors: it includes a triple VHF communication system with the ACARS function, a second-generation T2CAS collision avoidance system, and the ability to land according to ICAO category IIIA.

Due to the automatic piloting mode of the aircraft, not only additional gains in fuel efficiency are achieved, but also high flight safety, because in this mode, the fully remote flight control system (FCS) is protected from accidental errors. The fail-safe remote control architecture eliminates the need for mechanical redundancy entirely. Repositioning of the horizontal stabilizer is also carried out electrically. This helped optimize its dimensions for a high degree of controllability. The Superjet 100 is the first to use algorithmic protection against runway tail contact during lift-off, eliminating the need for mechanical shock absorbers found on other aircraft.

SaM146 engines are manufactured by PowerJet, a joint venture between Snecma (France) and NPO Saturn (Russia), taking into account all the requirements of the Sukhoi Superjet 100 family of aircraft. The new modular SaM146 engine combines the successful experience of using CFM56 with the use of modern technologies and a reduction in the number of components by 20%, significantly reducing operating and maintenance costs while achieving unrivaled performance and reliability. The latest third-generation Autonomous Digital Engine Control (FADEC) system with redundancy optimizes flight operations while reducing fuel consumption. The interchangeability of components of the left and right engines allows us to reduce the range of necessary spare parts. It is possible to replace the blades without removing the engine from the wing. Thanks to new technologies embedded in the SaM146 engine, all aircraft in the family exceed current ICAO noise and emissions requirements. Nacelles with high sound absorption and low drag provide increased comfort inside the cabin.

The SSJ100 cockpit is equipped with intuitive controls and an electronic display and alarm system the newest complex avionics from Thales and a fully digital fly-by-wire flight control system. Fully digital fly-by-wire flight control system with side-stick controls optimizes aircraft performance, reduces crew workload, reduces fuel consumption and provides protection against aircraft overrun.

The "dark and quiet cockpit" concept provides superior situational awareness and crew environment through an ergonomic cockpit design with five large LCD displays.

The DSUP is based on three upper-level computers (PFCU - Primary Flight Computer Unit) and complementary lower-level computers (ACE - Actuator Control Electronics). PFCUs process cockpit commands to the ACE and optimize aircraft performance in all flight modes. At the same time, at the first serious failure there is no need to switch to direct control, and the flight characteristics remain at a sufficient level of controllability. The high performance technology and weight perfection of the Sukhoi Superjet 100 is also achieved by the implementation of a fully fly-by-wire control system for retracting/extending the landing gear and the braking system.
