For 2016, Pilatus’ best-selling single turboprop PC-12 NG offers greater speed, better takeoff and climb performance, more cabin comfort, greater range, and a quieter cabin with no increase in fuel burn or operating cost. This boost in overall efficiency is exemplary of the core Pilatus tenet of being an environmentally conscious aircraft builder. The 2016 Pilatus PC-12 NG cruises at a new maximum top-speed of 285 knots (528 km/h) thanks to an aerodynamic optimization effort which analyzed every square inch of the exterior of the PC-12 NG to come up with a number of enhancements to reduce drag. Several subtle, but important changes contribute to the increased speed with no additional power. The under wing flap actuator fairings for example were redesigned for smoother airflow around them and the cabin entry door handle was changed to a flush fitting design. Gaps and joints around the flaps were sealed, and several antennas were repositioned to align with localized air flow patterns. The most noticeable change to the 2016 PC-12 NG is the standard five blade graphite composite propeller. Designed specifically for the PC-12 NG by Hartzell, this new propeller reduces cabin noise levels, improves takeoff and climb performance, reduces life cycle maintenance costs, and is easily repairable in the field. The propeller blades feature a nickel cobalt leading edge and are fabricated using aerospace-grade carbon fiber monocoque structural design. The thin blade shape is also optimized for low drag. The new propeller is certified for unlimited life. With a composite propeller, repairs are performed using epoxy, as opposed to filing away material on an aluminum propeller. In this manner, the composite blades are restored to factory-new dimensions at each overhaul interval. By the third overhaul cycle, the composite prop returns a significant value relative to the metal prop.
