The United Aircraft Corporation (part of Rostec Group) has updated the official characteristics of the MC-21-310 aircraft. According to the new data, the estimated range has decreased from 5100 to 3830 km.
Now the Russian aircraft is significantly inferior in this regard even to the previous generation Airbus and Boeing aircraft — A320ceo and B737NG. What does this mean and why is it critical for the aviation industry — explains "The First Technical".
New Data — A Real Machine Instead of a Project
The UAC website states that the maximum take-off weight of the MC-21-310 remains the same — 85 tons, but the range in a two-class configuration has been reduced to 3830 km. Rostec explained that this is not about a "reduction in capabilities", but rather a clarification of calculations.
The technical specifications of the Ministry of Industry and Trade in 2009 already indicated a range of 3500 km with 180 passengers. The state corporation recalled that any aircraft evolves in the process of refinement and testing.
Why the Range Has Decreased
According to sources, the aircraft became almost 6 tons heavier in the process of import substitution. This ultimately led to a revision of the characteristics and an increase in the maximum take-off weight. But at the same time, the adjustment opens up the potential for future development of the design — with optimization of units and aerodynamics, an increase in range is possible.
Domestic Flights in Priority
Even with a new range of 3830 km, the MC-21 is capable of performing flights from Moscow to Novosibirsk without refueling. According to UAC estimates, this range covers up to 80% of Russian passenger traffic, which falls on routes up to 3000 km.
The situation with the adjustment of the previously declared advertising characteristics of the MC-21 will raise questions among airlines, said aviation expert, Executive Director of the AviaPort agency Oleg Panteleev. In practice, this may mean that the aircraft is not suitable for all operators.
A similar situation was with Soviet aircraft, for example, with the Tu-154. Work on optimizing the design and aerodynamics of the MC-21, on the power plant, units and systems will continue, and therefore we can expect a gradual improvement in the characteristics of the aircraft during the current decade.
The Aircraft Will Not Fly to Dubai from Moscow, But…
However, not everything is so bad. Yes, the MC-21 will not be able to operate on a number of routes. For example, from Moscow it will fly at best to Krasnoyarsk, but not to Irkutsk or Ulan-Ude.
From the regions to Southeast Asia, too, without chances. Dubai from Moscow is also unlikely. However, the technical specifications for the MC-21, as Rostec claims, mentioned 3500 km.
Let's remember that the same Tu-154, which became the main "workhorse" of the narrow-body fleet of Russian airlines until the mid-2000s, had enough range for most destinations. Indeed, now 95% of flights of Russian airlines operating on narrow-body aircraft have a length of up to 4000 km, and 80% – up to 3000 km.
