Since it's such a nice day, I'm going to quibble. Where is it written that
you have to track the inbound course when outbound? IOW (I sense that you
fly in the Northwest, specifically western Washington), if I am coming from
the west to shoot the ILS into Paine, and my outbound turn over RITTS takes
me east of the extended runway/localizer, I am perfectly justified in flying
parallel to the localizer if I want to....the protected airspace is plenty
wide. I have seen dozens of instrument students work themselves into a
frenzy trying to get established outbound on the inbound, if you catch my
drift (no-wind conditions g).

Well, required in the sense of geometry or what?


Yes, in the sense of geometry.

If you have to turn around, you have to turn around. And since the
procedure turn =shape= is not usually prescribed (except that it happens
on one side of the course) it's just a sexy u-turn.


The *inbound* turn is usually not prescribed. The outbound leg is
required to be flown along the depicted route. In the case of the example
here, that requires a greater than 130 degree right-hand turn from the
transition route.

You only get to make up your turn on the way back in.

If the procedure allowed one to simply fly a standard-rate right-hand turn
after crossing the VOR, to return to the inbound leg, I might not have as
big an issue with the idea that the procedure turn is required. That's
still more complex, but it's reasonably efficient, does result in one
being established on the inbound course earlier, and is much less likely
to wind up with the airplane outside protected airspace (because there's a
lot less maneuvering going on).

But it doesn't. It requires that one first turns outbound, gets
established on the outbound course, and only then reverses course (again)
to come back inbound.

Not quite. As you quoted:

"A procedure turn is the maneuver prescribed when it is necessary to
perform a course reversal..."


It doesn't say "only when it is necessary", and the quote does not imply
it's the =sole= purpose of the PT.


It's the introductory sentence to the entire section on procedure turns.
I don't think it's a stretch *at all* (as opposed to some of my other
interpretations) to believe that they are describing *exactly* why a
procedure turn exists.
