Overview
The S-76D helicopter is truly the next step in helicopter technology, setting a new standard of excellence that S-76® helicopter operators have come to expect. Power and performance are enhanced by all composite main rotor blades and optimized Pratt & Whitney Canada PW210S engines with dual FADEC controls. Its quiet tail rotor will allow for reduced external acoustic signature and gain acceptance with the communities where it operates. Pilots will appreciate the state-of-the-art integrated Thales cockpit, its increased range and its ability to launch into known icing conditions. With the increased measures for a quieter cabin, passengers will enjoy a heightened travel experience.
