KIWA Approach Plate Question

Also, how would you identify being outside of 10NM from SNOWL with only the minimum navs required for this approach?

10 miles is your PT protected airspace for up to Cat D aircraft. Cat E aircraft require 15 miles, hence the note on the plate here that says "Cat E procedure turn not authorized", since this approach only has 10 miles (remain within 10 NM). The PT can be flown at up to 250 knots, provided the pilot takes into account speed/bank angle, etc, to remain within protected airspace. FAA recommends 200 kts, unless aircraft limitations don't allow. At all speeds, the pilot must insure his plane remains within the PT protected airspace.

Also, remember that for this type of PT, you're not locked into the 45/180. You can execute an 80/260 reversal, or even a teardrop holding-style entry/course reversal if you're so aligned, and the teardrop course is within 30 degrees of the PT course. In all cases, insure you remain within the PT protected airspace.
