In early May 1961, the first ''Turbo Porter'', powered by a Turbomeca Astazou II turboprop engine, performed its initial flight.[Fricker 1962, p. 38.] In comparison to its earlier piston engine-powered incarnation, the Astazou II-equipped ''Turbo Porter'' had an increased gross capacity and top speed, as well as benefitting from the engine's automatic handling functions. These benefits came at the expense of the greater initial purchase cost and higher fuel consumption

The initial turbine-powered models of the PC-6 were equipped with the Astazou II powerplant, however complaints on the reliability of this engine led to another early turboprop powerplant becoming available for the PC-6. This was the Garrett AiResearch TPE 331. Some operators such as Air America chose to retrofit their Astazou II-powered PC-6s with the TPE 331 engine.[Leeker, Joe F]

Due to the type's favourable STOL characteristics, described by the magazine ''Flying'' as being "one of the most helicopter-like airplanes in terms of takeoff performance", Pilatus has deliberately marketed the PC-6 towards helicopter operators at times, feeling the type to be complementary to their typical mode of operation. According to Pilatus, the PC-6 can provide very similar surveillance capabilities to a rotorcraft at a significantly lower cost to operate and procure.[Moxon, Julian]
