unctuous thanks that was the pic I was trying to load the pt6 has 3 governors. one for the FCU, two for the prop, and one for prop runaway ie: the hydraulic overspeed governor. The N1 or FCU controls fuel flow governing N1 speed set on a rear mounted accesory pad. prop governor sets speed of prop with the FTG set at normally 106% of selected prop releases p3 bleed air which reduce fuel flow on the FCU mounted on the top of the reduction gear box primary prop gov/FTG are combined, the HOG releases prop hub oil to govern as a last ditch in Prop overspeed situations. Don't know if the Turbo Mallard has the centripetal start lock system, this allows props to start in the ground idle position.

There are many versions of the PT6A. Don't confuse the engine with the accessories. These can vary depending on what airframe to which the engine is fitted, and what type of propeller is powered.
