    Great videos Matt. Technical question– what is the logic of having a propeller pitch control since direct drive engines (Garretts and Allisons) operate for all practical purposes at a constant rpm? In free turbine engines are there throttle/propeller rpm relationship constraints as on a reciprocating engine set up? Thanks, Paul.

      Hi Paul,

      I’m not familiar with direct drive turboprops as the Porter uses a P&W PT6 free turbine. On the whole, the propeller pitch control lever is left fully forward throughout all stages of flight to maintain a propeller rpm of 2000. There’s no requirements to change it like there is with a piston driven engine as it’s self governing. In the C208 I used to fly (also with a PT6) we only changed the propeller rpm for passenger comfort during climb and cruise.
