Let L-410 Turbolet is a Czech (Czechoslovak) passenger and transport aircraft designed for regional transportation. It can carry up to 19 passengers or 1.7 tons of cargo. Among the advantages of the model are reliable design, safety, heat resistance (-50 ... +50 ° C), the ability to land on a short unpaved runway. The first prototype took off on April 16, 1969, and more than 1200 units have been produced since production began in 1971. The main buyers of these machines are Russia and the CIS countries. They are also used in Asia, Africa, Europe and South America.
History reference
The development of the L-410 aircraft began in the mid-1960s by the Czechoslovak aircraft building plant Let Kunovice according to the drawings of the Taganrog design bureau Beriev. The Soviet airline Aeroflot was looking for a replacement for the outdated Antonov An-2 turboprop models. The new aircraft were supposed to communicate with regional settlements located in various climatic zones - from the tundra to the subtropics. The most important conditions were compactness (capacity up to 20 passengers), high efficiency, short acceleration, the ability to land on unpaved runways. The turboprop scheme was perfect for these purposes.
The production was entrusted to the company Let as a member of the Council for Mutual Economic Assistance of the socialist bloc. The XL-410 prototype performed a test flight on April 16, 1969 under the control of factory pilots Vladimir Vlk and Frantisek Svinka. The first examples were equipped with Pratt Whitney Canada PT6-A27 engines and Hamilton Standard three-blade propellers.
When the development of the Czechoslovak-made Walter M601 engines was completed, the PT6 power plants were replaced with the M601A (later the M601B), and the three-bladed Avia V508 propeller appeared on the aircraft. A prototype with new equipment was prepared in 1973, and in 1974 it made its first flight. The model received the designation L-410M. In 1975, deliveries to the USSR began.
Description
Turbolet belongs to the class of non-pressurized all-metal aircraft, for this reason, the flight altitude is limited to 4200 km above sea level. The aircraft is capable of climbing above 6,000 km, but in this case the use of oxygen masks is required.
Two 3/5 blade turboprop engines are highly efficient and have sufficient thrust for short-range takeoffs. However, the speed had to be sacrificed - 300-335 km / h in older versions and 417 km / h in the new NG version. However, this is not critical for regional flights.
The passenger compartment is compact, 5-7 rows. To the right of the aisle there are 2 chairs, to the left - one at a time. The seats are comfortable enough. In the back there is a toilet with a washbasin and a mini-wardrobe. There are VIP versions with a sofa (sleeping place), soft armchairs, a coffee table, a TV, a kitchen-bar and a refrigerator.
Flight safety is ensured by a double hydraulic circuit (main and emergency) and an automatic reduction system (availability depends on the modification) in the event of a breakdown of one of the motors. The main electrical system operates at 28 VDC. Anti-icing is provided by front pneumatic defrosters as well as electrically heated propellers, cockpit windshields and air pressure taps.
Specifications
The parameters of the L-410 aircraft of various modifications are presented in the table.
Since 2014, a special version of the Let-410 E20 with skis on the chassis has been developed. In April 2017, this modification was successfully tested at a Russian polar station 100 kilometers from the North Pole, deployed on drifting ice.
This is a modification with a shortened take-off and landing length, the take-off run is only 456 m. It differs from the classic version:
- extended fuselage;
- improved braking system;
- increased wing area;
- reduced to 15 seats with a capacity;
- fixed stabilizer (vertical tail).
The wings are equipped with spoilers and an automatic emergency control system (ABC). They help to control the rate of descent (lift) and are triggered in the event of a failure of one of the engines.
The first aircraft were powered by M601B engines. Later, their own modification of the M601D power plants was developed for them. The model entered production in 1976.
Let UVP-E
The E series is the most common UVP range. She possesses:
- increased maximum takeoff weight;
- stronger engines Walter M601E;
- five-blade V510 propellers.
The most productive version is the L-410 UVP E20. It allows you to transport 1.8 tons of cargo or 19 passengers. It can be equipped with a pair of Walter M601E (2 × 750 hp) or GE H80-200 (2 × 800 hp) engines. External fuel tanks can be installed at the end of the wing. The first flight took place in 1984, serial production started a year later.
Let L-410 NG series
In March 2018, the serial production of an improved version of the UVP E-20 started. She received the index L-410NG. The twin-engine turboprop transport / passenger aircraft manufactured by the Czech company Aircraft Industrie received an elongated fuselage, which made it possible to increase the volume of the luggage compartment.
The model is equipped with:
- a more powerful and quieter GE H85-200 powerplant with Avia-725 propellers;
- modern cabin from Garmin;
- wings of a new design with built-in fuel tanks.
The new engine meets stringent European noise and environmental regulations. The carrying capacity was increased by 400 kg, the speed was increased to 417 km / h, and the flight range was a record 2570 km for this model. The operating altitude remained the same - 4200 m, the maximum ceiling - 6096 m. The aircraft can operate continuously for up to 10 hours.

Production
The L-410 Turbolet turned out to be extremely successful. So much so that it is still being produced in various variations. Compact dimensions, short acceleration, loyal requirements for runways, the ability to transport both passengers and cargo, high efficiency, low operating costs allowed the technology to gain a foothold in the market of Eastern Europe and especially Russia for a long time.
The L-410 is manufactured by Aircraft Industries (formerly Let Kunovice) from the Czech city of Kunovice. Today the enterprise belongs to the Russian State Corporation "Ural Mining and Metallurgical Company". According to available data, from 1971 to 2016, about 1200 units were sold. There are about 350 aircraft of this brand in operation in the world today, both in civilian and military versions. Approximately 50 boards are used in Europe.
Several years ago, a project was launched to localize the production of Turbolet in Russia. On July 7, 2015, specialists from the Ural Civil Aviation Plant in Yekaterinburg assembled the first aircraft from Czech vehicle kits. In the future, it is planned to increase the share of spare parts, assemblies and mechanisms manufactured by domestic manufacturers.
Operators
Turbolet is operated by the Air Force and civilian airlines in more than two dozen countries in Europe, Central and South America, South Asia, North and Central Africa. Among commercial air carriers, the following companies have the largest fleet of Let L-410 aircraft (according to data for 2006-2016):
- "Universal-Avia" - 13 units (Ukraine);
- Atlantic Airlines de Honduras - 10 (Honduras);
- SEARCA - 9 (Colombia);
- Orenbuzhie - 7 (Russia);

- NHT Linhas Aéreas - 6 (Brazil);
- South East Asian Airlines - 6 (Philippines);
- Petropavlovsk-Kamchatsk Aviation Enterprise - 5 (Russia);
- Kin-Avia - 5 (DR Congo).
According to data for 2012-2016, military modifications are in service with the armies of Russia (27 copies), Libya (15), Slovakia (8), Czech Republic (6), Tunisia (3), Bulgaria (2), Honduras (2), Comoros (2), Estonia (2), Bangladesh (1), Djibouti (1), Latvia (1), Lithuania (1), Slovenia (1).
The L 410 UVP-E20 / L 420 aircraft, which is the latest and most modern successor to the renowned L 410 series aircraft, is a well-proven 19-seater turboprop small passenger aircraft with excellent technical parameters and operational reliability, ease of control and simple technical service.
My first acquaintance with this aircraft took place in Kamchatka. It was used very extensively on local airlines. He also flew to the Commander Islands. About this as something separately. Childhood....

The American engine company GE Aviation has announced the signing of a five-year contract for the supply of M601 and H80 engines to the Czech aircraft manufacturer Aircraft Industries. These engines will be supplied for the L-410-UVP-E20 turboprop aircraft assembled in the Czech city of Kunovice. The Czech company expects the production of this 19-seat twin-engined aircraft for local airlines to exceed 10 units per year in the coming years.
The M601 is already in use on the L-410. The H80 engine is an improved modification that will allow the aircraft to operate in hotter conditions and at higher altitudes. Aircraft Industries plans to certify the L-410 with the new engine in mid-2012. After that, owners of versions of the aircraft with the old power plant will be offered a re-engined H80.

Universal aircraft for local airlines (MVL), which replaced the An-2. The first foreign-made aircraft to enter domestic air routes. Other names: L-410, Let, Let L-410, Turbolet, Cheburashka.
Description
The development of the aircraft began in 1966.The first prototype aircraft, equipped with the Pratt-Whitney Canada PT6A-27 (2 x 715 hp), began to undergo flight tests on April 16, 1969. Regular operation of the L-410A aircraft at the end of 1971 was the first was opened by the Czechoslovakian airline "Slovo Air" from Bratislava, serving local airlines - by the beginning of 1974 it had received 12 aircraft. A total of 31 aircraft were built. Five aircraft (serial No. 720103-06 and No. 720201) L-410A with RT 6A-27 engines, built by the end of 1972 under the designation L-410AS, were transferred to the USSR the following year. The aircraft received Soviet registration numbers from USSR-67251 to USSR-67255. The first of them was brought to the airfield of the State Research Institute of Civil Aviation by the Czech test pilot Frantisek Svinka. The airfield people immediately called the handsome newcomer "Cheburashka". In 1973, flight tests of the L-410M aircraft, equipped with the Czech theater of operations Walter M 601A, began. The L-410M became the second serial modification of the Turbolet. In total, by the end of 1978, 100 L-410M / MU aircraft were received for the USSR Ministry of Civil Aviation.
In 1979, the production of the improved modification L-410UVP began, which became the main production model. This aircraft differed from the previous versions by an elongated fuselage, increased wing and vertical tail dimensions, the use of spoilers and the installation of a Walther M 601 V theater (2 x 730 hp). This aircraft passed the certification program in the USSR and was accepted into operation by Aeroflot. A further development was the L-410UVP-E variant with the more powerful M 601 E turbofan engines. The first flight of this aircraft took place on December 30, 1984. It is distinguished by improved takeoff and landing characteristics and a reduced noise level in the cockpit. In March 1986 he was certified in the USSR. A modification of the L-420 with more powerful turbofan M601 F (2 x 778 hp), increased take-off weight (6.8 t) and improved flight characteristics (flight tests of the aircraft began in November 1993) was developed.
Since 1969, 1104 L-410 of various modifications have been built, 862 of them ended up in the Soviet Union. By the beginning of 1992, about 750 L-410 aircraft remained in the USSR.
Modifications
L-410UVP Short-haul passenger aircraft, modification of the L-410 aircraft, in which the take-off and landing distance is reduced. The abbreviation "UVP" means "shortened take-off and landing". The first launch took place in 1976. Produced by the Czechoslovak company "Let". The aircraft is equipped with a common Soviet-Czechoslovak joint avionics complex. This aircraft differs from the previous versions by an elongated fuselage, increased wing and vertical tail dimensions, the use of spoilers and a more powerful engine.

The development of the L-410 aircraft began in 1966. The first sample rose into the air after 3 years. He carried the first passengers at the end of 1071. This flight was carried out by the Czechoslovakian company Slov Air. The following year, Czechoslovak developers transferred 5 vehicles to the USSR. Despite the good flight characteristics, work on improving the aircraft continued. So, already in 1973, the L-410M, equipped with an engine manufactured in Czechoslovakia, took to the air.
The next, more advanced modification of the L-410UVP appeared in 1979. It was distinguished by its large wings, vertical tail, and a longer fuselage. This modification became a production model.
But her improvement continued. In 1984, the L-410UVP-E variant appeared, featuring more powerful engines. After 2 years, the aircraft, which received a certificate in the USSR, again received a different, powerful engine.
In the 90s, due to a decrease in demand, aircraft production fell to 2 - 5 per year, although before that they were produced by 50 per year. This continued until 2008, when 51% of the shares were purchased by the Ural Mining and Metallurgical Company. The production of aircraft increased and reached 11 units in 2013. There was no further increase. Currently, most of the aircraft are in poor condition. But some of the L-410s continue to fly.
This small plane has enjoyed and continues to enjoy some popularity. It has been exploited and continues, albeit without its former intensity, to be operated in 40 countries. On local airlines, it has proven itself well even in Australia and Greenland.
In Russia, the L-410 is rarely used, since a significant part of local flights are not operated. These aircraft are available in the parks "KrasAero", "Orenburg" and the airline PANH, located in Buryatia. Interest in the aircraft is shown in the Ministry of Transport and the Ministry of Industry and Trade, as well as in some regions with large territories with an undeveloped road network.
Although the developments used in the L-410 are far from new, a number of innovations introduced into it in subsequent years make it possible to operate the aircraft with an efficiency no less than existing modern models. Due to the use of new engines, its flight range has been significantly increased, and various cabin options allow it to be used not only as a passenger one. The advantage is the ability to use this aircraft at temperatures from minus 40 to plus 50 degrees. It should also be clarified that the L-410 can land on an unpaved runway.
The liner salon: comfortable and uncomfortable seats
Although the cabin of this small plane is designed for short-haul passengers, it offers all the comforts you can get. The seats are not much different from those installed in large airliners. Of course, sitting in them for a long time will be tiring, but this machine does not perform long-distance flights.
The chairs are arranged in 7 rows. But there is an option in which there are fewer rows. In this case, the number of seats is not 19, but only 17. In the first option, those in the first row are recognized as the best seats. There are only 2 of them here: A and C. They are located on the left and right at the windows. For a tall passenger, seat B, located in the second row, is most comfortable. There is no chair in front of him, which makes it possible to quite comfortably place his legs.
During the flight, the noise of working engines is clearly audible in the cabin. But it is not very loud. So passengers can talk to each other, as they do in any form of transport. There is no need to shout in the cabin.
A well-installed heating system ensures a comfortable temperature during the flight. So even in winter you can stay here without warm jackets, coats, fur coats. They fit easily into overhead racks. These shelves are enough for all passengers, but you cannot place something voluminous there.
It is also difficult to accommodate passengers with large bags. Going on a trip with more or less substantial luggage, you should place it in the luggage compartment. There are two such compartments in the plane. Although they do not differ in large volumes, there is enough space for everyone.
Usually, when flying, many passengers simply do not know what to do so that the travel time passes unnoticed. In the cabin of this aircraft, passengers in the front rows are usually engaged in monitoring the work of the pilots. There is no blind door between the passenger compartment and the cockpit, so it is easy to observe what is happening in the cockpit.
Since flights are carried out at a low altitude, usually not exceeding 3 thousand meters, the pictures floating below are clearly visible through conveniently located windows. The advantage here is that you can look at the ground from any row. The view is not obscured by the wings above the windows.
Of course, we should also mention such convenience in this small plane as the toilet. It is located in the tail section. Of course, for those in the sixth (seat A) and seventh (seat B) rows as a passenger, such a neighborhood brings inconvenience. However, the toilet door opens not towards the aisle, but towards the front door, and there are not many passengers in the cabin.
The narrow aisle is also a special feature of the cabin. It is almost impossible for two to miss each other. But there is no movement towards each other on the plane. In addition, flight attendants with carts do not appear in the aisle, as is the case in large planes.
In the cabin layout for 19 passengers shown below. In the cabin layout for 19 passengers shown below, the numbering usually starts from the left as usual. The order of the seats is A, B, C. Number 5 denotes a toilet, number 11 - a luggage compartment.
Does the plane have a future
In recent years, measures have been taken to revive small aviation in Russia. This also applies to the L-410 aircraft. Workshops for its production are mounted in the "Titanium Valley", where it was decided to place them UZGA. The commissioning of production facilities should take place in 2018. It is planned to produce aircraft not only for civil aviation, but also capable of performing a number of other tasks. This will also include the production of vehicles intended for the armed forces.
In all cases, the production will use the latest technology, which will make the aircraft safer and more comfortable. The passenger version of the L-410 will be used on intraregional lines, as well as for communication between cities of different regions with an insignificant passenger flow between them.

Conclusion
The available information suggests that the L-410 aircraft has not exhausted its possibilities for continued operation and further improvement. Its special advantage is the ability to take off and land, where other airliners cannot. The ability to fly at high and low air temperatures allows it to be used in a wide variety of climatic conditions.
The number of passengers carried, although not as large as that of larger liners, is, in most cases, sufficient for passenger requests, since the plane is usually used on intraregional lines, or on routes between cities that are not so far apart from each other. When flying, passengers are in conditions that are almost equal to those of a large airliner. Further improvements will make it possible to make these conditions more comfortable.
Calculating the cost of a taxi to the airport
The Let L-410 Turbolet airliner was born in the late 60s thanks to the Czechoslovak aircraft engineers from the Let company. This aircraft was to be used only by local airlines, the main customers of such aircraft were the USSR. Also Let L-410 Turbolet was delivered to Bulgaria, Brazil, Hungary, East Germany, Libya, Poland.

The cabin of the Let L-410 Turbolet aircraft
The seats in this aircraft are arranged according to the 2 + 1 principle, which automatically makes the single row more comfortable than others, but the double row is perfect for flights with a company or for those people who cannot be without communication throughout the flight.
There are only two crew members in the airliner, a pilot and a flight attendant; due to the small number of passengers, she manages to pay attention to all her passengers, leaving no one unattended or without providing any service.
Due to the fact that the wings of the aircraft are located in the upper part of the side, all passengers can enjoy the views from the windows without any difficulties, and they will not be obstructed by the view from the window of the wing of the aircraft or other parts of it.
If you look at the diagram of the aircraft, you can immediately determine the best places, the diagram of the aircraft will be presented below. You can see this for yourself. There are only 6 rows in the plane, but the seats under the letter "A" located on the right side of the plane have only five seats.
Not the best places
Row 1. It seems that it can be called the best row, but if you consider this row in detail, then it cannot be called the best row. Firstly, it is located close to the technical room, light can be constantly on in it, and various noises can be heard from there during cooking or when using other equipment. Also, place B in this row is located next to the partition, which makes it impossible to calmly stretch out your legs and enjoy the flight.
But this series also has its advantages, you will always receive food first, and thanks to this you will have a large assortment to choose from. You can also safely go to the kitchen to ask for something. And the main plus of the first row is that you do not have to constantly collide with other passengers, and you can get out of the plane very first.
Row 6. It has only two seats, it is located on the walls, which is why it may not be possible to recline the back of the chair in order to make the flight in a comfortable position. You will also have to observe the constant movement of people to the toilet, it is possible that there will be a queue, and one of the passengers may lean on your seat, which will cause some discomfort. Also, unpleasant sounds can be heard from the toilet, but this is not the worst thing, from the toilet it can go, an unpleasant smell that will have to be put up with throughout the flight.
Row 5. The main disadvantage of this row is that it is located close to the restroom and along the way, people will accumulate near your seats, waiting to turn to the toilet, and an unpleasant smell can come from the toilet, which will cause a lot of inconvenience during the flight.
The best seats L-410
The best places include rows from the second to the fourth, on the second row there are all the privileges of the first row, but the estimates and noise from the technical room will not cause you such inconvenience as the first row. The third and fourth rows are located in the middle of the cabin, the technical rooms will in no way be able to disturb their harmony during the flight. Since the toilet is far enough from them and the queue simply does not reach them, and even more so the sounds and smells from the toilet. The same can be said about the kitchen, estimates and sounds also do not reach them, thanks to this they can safely enjoy flying in the L-410 airliner.
