See also the TERPS. Look how much airspace is protected if you don't go below PT altitude.

1) Go to FAA Order 8260.3B - United States Standard for Terminal Instrument Procedures (TERPS)

2) Click on Basic including changes 1 thru 18

3) Find Chap 2, Page 12-1

4) look at figure 5 and table 1A

If you haven't seen how much airspace is protected before check it out; At or below 6,000 MSL you're protected out to 7 NM on the side opposite the PT, and 8 NM past the PT distance...for a total of 18NM from the VOR on the PT side. Thus, from end to end you have 25NM protected. The thickness works out to be about 16NM at the widest point. You do have room to get turned around for the PT. (I am including the secondary areas, just FYI)
