Mi-171A2 is the most up-to-date modification of Mi-8/17 type of helicopters. The aircraft is equipped with new engines with a digital control system, an effective rotor system with composite blades and an improved aerodynamic profile. As a result of the modernization, the power reserve has increased significantly, the cruising and maximum speed of Mi-171A2 compared to commercially produced Mi-8/17 helicopters have increased by 10%. The helicopter may be efficiently operated in the daytime and at night, in high altitudes, in high and low temperatures, high humidity environment and over water. The use of helicopter digital onboard equipment complex on Mi-171A2 made by the "glass cockpit" principle has reduced the crew to two people. For safety enhancement modern systems for prevention of the collision with terrain, other aircraft and obstacles in the flight path have been installed.
