PT6C
High powered performance for medium-class helicopters.
1,600 to 2,000 shaft horsepower class
The latest technology for the new-generation medium-class helicopters and tiltrotors. Unmatched performance, continuing the PT6 legacy.
Overview
Setting a new standard in its class
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.
Versatility on a wide variety of applications
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. More than 2,650 PT6C engines delivered to power helicopters in service with 308 operators in 78 countries in such applications as oil exploration, emergency medical service, maritime patrol, business and utility operations.
