There would have to be other factors here that we do not yet know about. The instructor is a very experienced well known gentleman, as was the student.
I remember there being a mod that came out for the C208 that was required for UK certification, that among other things meant some kind of additional "gate" on the power lever to get it forward of flight idle, I don't remember anything being modified or different about the prop lever. My memory is a bit scratchy, does any one else have any thing to add to which might have troubled them in unfeathering the prop?
