The Mi-26t is the world's largest heavy-lift helicopter. It is capable of lifting large size cargo items weighing up to 20 tons, either inside the cargo compartment or on an external sling. A combined internal and external load configuration is also permissible, providing the total load does not exceed 20 tons.

The helicopter can be widely employed at construction sites, airlifting and mounting heavy industrial equipment, drilling rigs, electric power line installations, bridge construction, logging operations and other complex civil engineering operations as well as on fire-fighting duties.

High placement accuracy of external loads is achieved using the special front and rear auxiliary cabins.

A clearance control system is available for handling items of large volume during loading.

The helicopter is provided with engine starting facilities using internal power, special ladders are not required as both engine and gearbox cowling, when in open position, serve as maintenance platforms.

The APU (Auxiliary Power Unit) provides ground power for internal engine starting, electrical and hydraulic systems together with air conditioning of the flight crew compartment.

The flight crew compartement is pressurised and affords excellent visibility, with a well laid out, integrated flight/navigation system that meets with modern requirements.

The Mi-26t can fly day or night in good and bad weather conditions.
