Airbus Group NV has launched a new twin-engine rotorcraft with the operational start-up of Airbus Helicopters's upgraded EC135 T3/P3 of Aiut Alpin Dolomites, a northern Italy-based Alpine mountain rescue service. Aiut Alpin Dolomites' operations benefit from Airbus Helicopters' enhancements incorporated in this latest variant of the versatile EC135 family, which include significant power reserves for increased safety margins during flight and while maneuvering; an improved flight envelope, especially in hot-and-high environments; and an increased maximum takeoff weight of 2,980 kg. The upgraded EC135 is available in two versions with its corresponding upgraded engine options: Turbomeca's Arrius 2B2 "Plus" for the EC135 T3; and Pratt & Whitney Canada's PWC 206B3 for the EC135 P3.
