Hi, y'all -

The RNAV (GPS) RWY 18R into KHSV

http://www.naco.faa.gov/d-tpp/0411/05488R18R.PDF

has a transition route from RQZ VORTAC to an IAF, HATAS. The transition
route is bearing 322 degrees, 2.1 miles. There is a note "Procedure NA for
arrivals at RQZ VORTAC on Airway Radials 261 CW 010". There is an airway at
RQZ on radial 261 and one on radial 010, nothing in between. The note
specifies a prohibited arrival sector, but also implies that the prohibition
applies only applies if arrival is on an airway. I don't understand the
reason for the word "airway" in the note. Anyone have a clue?

Also, how would one fly this approach in a nonradar situation, given an
arrival on one of the two airways? Would one give a position report and
request direct HATAS when a few miles from RQZ? One might have to be at a
higher altitude to make an uncharted off-route transition. I believe the
MVA in that area is 3000; can ATC apply MVAs in nonradar conditions?
