approach. The outbound segment, if flown with positive course
guidance, gives you a chance to establish the crosswind component.
Fly it by DR, and you miss the chance.

Needle position and movement trend will indicate what you're dealing
with. At best I will grant you there is a theoretical reduction of
precision of measuring the x-wind component, but I suspect in most
cases the difference in the two approaches will be nugatory.

If it were unsafe
the procedure would not be allowed.

You truly need to disabuse yourself of that notion before it kills
you. Check out the VOR-B for LVJ sometime - a perfect example of how
you can fly an approach with equipment well within allowable
tolerances, to well within PTS standards, and still die.

Yes, and we allow people to drive 55MPH, despite the fact that some
people get killed doing just that.

I agree that final approach segments often demand higher precision
than what "the rules" require. My favorite is the ILS 5 to Lawrence,
MA, which ought to be called the cannonball run:

I'd be more interested however to find a case where a hold-style
procedure turn *clearly* increases risk versus the 45-180 PT. I
haven't seen one yet but it's a big planet, I suppose there's one out
there somewhere.
