PC-6 B range
Dear Aerobat77 despite your vast experience regarding the PT-6 family i have to notice that you' re misinformed regarding PC-6 operations.
PC-6 are indeed cleared to enter the B range in flight, as you can see in any PC-6 POH, the bit of information that' s probably missing is the fact that the PCL hard stop is set so that a movement of said lever toward idle brings it in the B range without the need to lift up the lever.
Just to clarify even more lifitng up of the PCL to go toward the Reverse range in flight is forbidden on PC-6 too.
I tried to keep it simple and concise, hope it helped.
Regards
