VOR/DME Approach Question

As a procedures sort of guy I think it was stupid to remove the DME ARC,
especially since it is a VOR/DME IAP. If the system worked the way it should,
AVN-100 would not have removed the ARC because GPS overlay was added; rather,
they would have removed it because your airspace staff for that area asked for
it to be removed. Or, in the alternative the DME ARC might have failed a
periodic flight inspection, which is more common these days as the VORs get old.

My question concerns the course reversal at MINES. If you were flying
this
approach from due east of MINES, "cleared approach", what do you do at
MINES
to get on the approach course?

Thanks everyone. When I learned this IAP back in the day, it had a DME
arc
off of HCH Vor to get to the IAF, and then you turned down the approach
course. When they slipped GPS into the system, they changed the IAP and
eliminated the arc. Of course, no one told the controllers about the
change- as usual they just published it. I never thought about the
difference. Looks like I need some refresher training...

Chip, not to be argumentative, but IMO the change to the procedure
makes absolutely no difference here.

Obviously it made a difference to me. :-)


What the pilot did was absolutely correct. Had the DME arc been
charted as before, his actions would still have been correct provided
the hold-in-lieu was still charted. Removal of the DME arc is not a
function of adding the GPS overlay; there are VOR/DME approaches with
GPS overlays out there that include a DME arc as an option. UTS
VOR/DME or GPS-A (http://www.naco.faa.gov/d-tpp/0408/05813VDGA.PDF) is
one example, though it's NoPT all the way around.

I have no doubt that the pilot made no mistake.


The key here is this - if you're vectoring the guy to the FAC, no
procedure turn. If you've cleared him direct to the IAF, he does the
PT. It's just that simple.

No kidding...


I guess my question is this - why was this a problem? The pilot asked
for the full procedure, and your traineed cleared him for it. The
phraseology was not quite perfect, but well within the range of
variation, at least based on my experience. What am I missing?


No one said this was a problem. I posted this to gain personal insight, and
nothing more. I don't think you're missing a thing.
