Default 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).

: engine. The air cleaner damps some of the pulsation. Re-indexing the
: prop might improve smoothness and maybe performance.

Re-indexing our O-360 prop reduced the perceived vibration... not sure if it
was real or "we did all that work so it *must* be better." Unfortunately, we
reindexed it to make it less conducive to hand-propping.
