beta range... uff c,mon, let it be... its the range betwenn flight idle and ground idle but above reverse. the only range which is not governor controlled and you have a direct control of blade pitch with the power lever. reverse is like alpha range governor controlled again...
Okay, this explains a lot. You appeared like you might have known what you were talking about, initially, but clearly you don't. This is especially true regarding the TPE-331, but evidently you don't understand propeller systems very well, either. Thanks for clearing that up.

All ranges are governed. Do you know which governors manage which range?

Show us you know something about the motor.
seems logical to me , the pt6a has no pitch locks , but then you loose any thrust from the propeller ( you may have an enourmous torque indication due to the resistance when the core tries to drive the feathered prop)
This also backs up the fact that you really don't know your equipment very well, at all. This explains many of your previous comments and questions.
in the meantime ... be careful with claming other people lacking in turboprop operation fundamentals when you say such nonsense ( tpe331 is not a singleshaft, running it in feather is possible...)
Thanks again for once more confirming that you really don't know this material. We get it, thank you.

i a splitshaft you can do it, no question.
A PT6 is not a "split shaft." It's a free turbine. A TPE-331 is not a "single shaft" or "fixed shaft." It's a geared engine with a short drive shaft, driven by gearing, and the arrangement accounts, in part, for the cause of "shaft bow." Not that you should be expected to understand this, of course.

some claim it indeed the range all below flight idle, but, thats not fully true.

now i know you never operated one.
Thus far, you've been nearly 100% wrong with every guess you've made, ranging from operation of the engine to it's mechanical function, to your ideas and misunderstandings about propeller operation and your systems knowledge. Your comment here, then, is no surprise.

You don't understand beta. If you don't understand alpha or beta operation, then you don't know anything about the engine. Your previous comments suggested that you acted as a passenger or possibly a "copilot" in a Conquest (a single pilot aircraft, incidentally), so perhaps that explains your ignorance. If you stopped at ignorance, you'd be okay, but what you are clearly here, is a troll.
