Jim should have used "Face" instead of "Front," but the "Back" side of the blade
is indeed the side the pilot cannot see. Think relative wind. When the engine
is turning the prop on a tractor engine, the side the pilot CAN see is the side
that is impacted by the oncoming air. Only when the engine is windmilling does
the relative wind hit the side of the blade seen from in front.

This is a boat site, but it illustrates the issue:
