High powered performance for new-generation medium-class helicopters and tiltrotors. 1,600 to 2,000 shaft horsepower class and the latest technology. Unmatched performance, continuing the PT6 legacy.
The PT6C Series, with its latest advanced technologies, has been designed in the tradition of Pratt & Whitney's first helicopter engines to deliver outstanding reliability, durability and operating economics.
The PT6C Series sets a new standard in its class for power-to-weight ratio, fuel consumption, as well as durability in harsh operating environments. Advanced engine control ranging from Electronic Engine Control (EEC) to Dual Channel Full Authority Digital Engine Control (FADEC) further advances ease of pilot operation and maintenance diagnostics.
The 1,600 to 2,000 shaft horsepower class PT6C Series has been produced in four models and its versatility has been demonstrated on a wide variety of applications.PT6C engines have been delivered to power helicopters in service around the world for offshore, emergency medical services, search & rescue, business and utility operations.

The PT6C remains a PT6 in basic configuration, with its two-shaft layout consisting of a multi-stage compressor driven by a single-stage compressor turbine and an independent shaft coupling the power turbine to the output shaft. It also incorporates the latest advanced compressor, combustion and turbine technologies to provide an impressive power-to-weight ratio while delivering low fuel consumption, low emissions, high durability and excellent operating economics. With its modern engine control ranging from Electronic Engine Control (EEC) to Dual Channel Full Authority Digital Engine Control (FADEC), the PT6C Series provides ease of pilot operation and enhanced maintenance diagnostics to maximize engine refurbishment intervals.
