There is also a switch for a water-pipe, to load water from a lake or the see. Go into floating mode and descent to 25-28 ft, and hold this altitude with a floating pitch of -0,35. When loading water you have to adjust this setting to +1.00 or more, depending on the weight of water. You may fill up to 10000 liters. | |||

To lift the 27 tons of helicopter plus up to 15 tons of cargo (Variant Poschar up to 20 tons of cargo) you don't just need strong engines but also an appropriate main and tail rotor. Appropriate in this case means that the 5-bladed main rotor has a diameter of 35m and turns at about 120 rpm. The resulting circumferecial speed is about 220 m/s. That does of course produce a lot of torque which needs to be counteracted. Therefore the Russian engineers mounted a massive four-bladed tail rotor of 6.3m diameter at the very far end of the helicopter in about 7m height. | To lift the 27 tons of helicopter plus up to 15 tons of cargo (Variant Poschar up to 20 tons of cargo) you don't just need strong engines but also an appropriate main and tail rotor.

The Mi-6 helicopter has two auxiliary wings mounted high over the center of the fuselage. They are tilted upward to the front and provide up to 20% more lift at cruise speed. However they get in the way when hovering, so variants of the Mi-6 helicopter that need to hover a lot, like the fire fighter, often have no auxiliary wings. | The Mi-6 helicopter has two auxiliary wings mounted high over the center of the fuselage.

There is also a three phase 360 volts (400Hz) AC circuit on bord for operating the radios and the deicing equipment. This cirquit is fed by two alternators of 90 kVA each. The helicopter also features an auxiliary power group with an AI-8 gas turbine powering a generator of 24 kW. The auxiliary power group ensures that the engines are supplied with enough power for start-up. | ||
