Russian Helicopters plans to test Mi-171A2 multi-purpose helicopters in adverse weather conditions with air temperatures as low as minus 50 degrees Celsius, the company reported.

Two helicopters, as well as specialists of the Moscow Mil Helicopter Enterprise have already arrived in Yakutia where the helicopters’ trials will be held during a month.

The program of trials envisages about 20 flights at air temperatures ranging from minus 45 to minus 50 degrees Celsius and icing conditions.

In this situation, specialists will check the helicopter’s anti-icing system, its heating and some other auxiliary elements responsible for the rotorcraft’s uninterrupted operation at extremely low air temperatures.
