Higher payload by increasing the maximum take-off weight.
Airbus Helicopters Deutschland proposes the increase of the maximum take-off weight (MTOW) to 2950 kg. Thus, the payload is increased by up to 40 kg and can be used for operations in low altitudes (see flight manual FLM and Supplements FMS). An important content is the improvement of the main rotor system by installing a new generation of lead-lag dampers in the main rotor blades.
