Climatic tests of the newest Russian Mi-171A3 helicopter have started at the Yakutsk International Airport named after Platon Oyunsky. According to the press service of the air harbor, a testing ground has been set up at the airfield to check the operability of the machine in extreme cold conditions.
The tests are carried out by specialists from JSC "National Helicopter Center named after M.L. Mil and N.I. Kamov" as part of experimental design work aimed at confirming the certification characteristics of the aircraft. The main task is to verify the reliability of all helicopter systems at temperatures typical of the Arctic climate.
The flight test program includes 40 to 50 flights in various modes with a mass of 11 to 13 tons. Experts will analyze the behavior of the aircraft during takeoff, landing, and maneuvers in dense frosty fog and low temperatures.
During the tests, engineers will evaluate the operation of engines, fuel and hydraulic systems, and also check the stability of onboard avionics and controls in severe frosts. The data obtained will be key to completing the certification of the Mi-171A3 and its subsequent launch into mass production.
