Has retained all the best qualities of the Mi-8T helicopter and is able to carry a greater weight of the cargo (up to 4000 kg). To increase the flight distance, the helicopter can be equipped with additional fuel tanks both inside the helicopter and outside. The design and equipment of the helicopter makes it possible to operate it in an autonomous basing on unequipped platform. By improving the flight performance on the Mi-8MTV it is possible to perform specific types of work (such as laying the lines of high-voltage gears, conducting gravimetric survey of the terrain).
