Hi,
I have found it much more clear to refer to the propellor with regard to it's 'blade angle', (at it's reference point), which is usually pretty close to zero, mostly a little negative, because of the blade twist, when the prop is stopped, prior to ground starting.
That's assuming the prop is gear driven, not free turbine driven.
And is at 90 deg, or pretty close to it, when it's feathered.
That would make the cambered side normally forward facing!
Hope I haven't confused you (or me).
Cheers.
