Prop Indexing

The problem is that it's not clear to me whether or not saying "8-2" is with
respect to looking at the prop from the front (as one would be when servicing it), or
with respect to sitting in the pilot's seat (as everything else is always referenced).

The Cessna 172 manual says to position one blade over the TC mark on
the AFT face of the ring gear support (which is straight up when at
TDC), then rotate the prop clockwise (when viewed from the front of the
engine) to the first bushing and locate it there. That puts the prop at
about the 7:30/1:30 spot.
