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? Stan |

It is presumed you'll be arriving via airways to begin an instrument approach
procedure in a non-radar environment. If ATC has you on radar and wants to clear you direct to a feeder fix or IAF on an RNAV IAP, then that action supercedes those types of notes. The reason for the note is to enforce the 120 course change limitation after a feeder fix or IAF. Those limitations have always been in TERPs, but the FAA didn't chart such restrictions until within the past couple of years.

![]() "J Haggerty" wrote in message news:TvCid.98487$tU4.22080@okepread06... Tim is absolutely correct regarding the 120 degree turn. As for non-radar entry, you could file for airways to ELKED for the procedure, since that turn from the airway does not exceed 120 degrees, or arrive at ROCKET on other than those 2 airway radials. As for the wording, it probably should have been "Procedure NA for arrivals at RQZ VORTAC via V-xxx Eastbound and V-XXX Southbound", rather than the phrase used, which would have made more sense if there was more than the 2 airways within that spread. JPH Yes, I understand about the 120 degree turns, and agree that ELKED is viable, as it is an enroute waypoint on an airway, and the turn from there is only about 90 degrees. And your comment about the note supports my suspicion that it was just unskillfully worded. But what I am really still wondering about is not a TERPs issue but an ATC issue in a nonradar situation. If for whatever reason I was arriving on the airway from the northeast, if I flew all the way to the VOR, then the procedure is NA because of the large turn. However, if about 5 miles from the VOR on the airway, I gave a position report and requested direct HATAS, could ATC give me an unpublished off-airways route for the 5 miles or less to HATAS if I was at or above their MVA in that area. I observe that the note says "Procedure NA for arrivals **AT** RQZ...". I am trying to determine if the prohibition can be overcome by not arriving AT the VOR but leaving the airway before reaching the VOR so that the turn will be less.

I never say never about how controllers do things, but generally they won't use
MVAs (TRACONS) or MIAs (centers) if they cannot see you on radar. Stan Prevost wrote: "J Haggerty" wrote in message news:TvCid.98487$tU4.22080@okepread06...
