I'm hoping one or more of you instrument pilots (or controllers) could help
me with an IAP question. The airport involved is RKW, which is Rockwood,
Tennessee. The IAP in question is the VOR/DME RWY 22 into Rockwood. If you
have the plate or know the procedure, I hope you can help me out.

RKW airport lies about 2 miles west of the common Atlanta (ZTL)
ARTCC/Knoxville (TYS) Tracon boundary. Center owns the airport, but because
of the close proximity to TYS airspace, Center has to coordinate with Tracon
for clearances in and out of RKW unless the aircraft is arriving from the
east. TYS coordinates with Center for RKW arrivals from the east, and TYS
issues the approach clearance, as most of the IAP lies within TYS airspace.

Here's the situation. I'm instructing a newbie on the radar. We're working
combined sectors and we're busy working the main bang out of Atlanta on
our other freq. We have a RKW arrival from the east, an Army UH60/G. Route
of flight is Asheville NC direct RKW, a 30 minute delay at RKW, and then on
to Fort Campbell KY. The aircraft whopping along at 6,000 and "PLA RKW" is
in remarks on his flightplan. There is a large thunderstorm sweeping south
over the Knoxville airport and the TYS controllers are busy holding their
own arrivals for the storm to pass. To ease their workload, TYS calls my
trainee and begs him to work the approach into RKW. The trainee agrees
(good training experience). Good experience for me too, as I don't get to
work east arrivals into this airport very often.

The aircraft checks on at 6000 with a request. We issue the CSV altimeter
and take the request. The request is "Center, Army 569 would like to shoot
the full VOR/DME 22 into Rockwood, followed by a missed approach and a ten
minute hold at MINES and then on to Campbell." My guy and I do a quick
huddle as we dig out the chart.

Normally I would have keyed the mic and asked the pilot what he was going
to do when he asked for the "full" approach, but I sit behind my trainee
when he works the radio. I can over-ride him, but he's a Yank from
Pennsylvania and I'm from the Low Country of SC. Our accents are as
different as night and day, and the last thing I wanted to do was let all of
the Delta pilots on our other freq know they were dealing with a trainee.
Like dogs, they work in packs, smell fear and love to shred new meat. I try
to stay off the radio when I train.

The MIA for the area is 5000. The trainee clears the aircraft to "Descend
and Maintain 5000, cleared direct MINES, I have your request for the
approach". This is followed a minute later with:

"Army 569, twelve miles northeast of Rockwood, cross MINES at 5000 inbound,
cleared VOR/DME Runway 22 approach Rockwood, report established on the
approach."

Look at the plate. The aircraft is approaching MINES on about a 270
heading. He's maybe ten miles due east from MINES when he checks on with
his request for the approach and we clear him -MINES. I am expecting the
aircraft to proceed to MINES at 5000, turn left to intercept the HCH 060R
inbound, and fly down the approach on a 240 track towards the airport, doing
a drive and dive. In the event, the aircraft proceeds to MINES, turns left
all the way around to a 060 heading, and flies one turn in the published
holding pattern at MINES. Somewhere in the trip around the pattern, he
calls established on the approach. We put him on the CTAF, he does his
thing, later misses as planned and life goes on.

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,

Chip, ZTL

With the web, everybody's got all the plates. There's a bunch of sites;

Yup, that's what he was cleared to do. The AIM says:

I'm assuming you're thinking your trainee gave him radar vectors, but he
didn't; he cleared the flight direct to the IAF. Radar vectors would
have been:

"Army 569, twelve miles northeast of Rockwood, flying heading 270 to
intercept the final approach course, cleared VOR/DME Runway 22 approach
Rockwood, report established on the approach."

The pilot knew that. I'm guessing your trainee knew that, since he's
fresh out of studying this stuff in school. The only question is
whether the pilot's instructor knew that :-)

To be fair, the clearance as issued was a little funky. If the intent
was to have the flight fly the PT, I would expect the clearance to sound
like:

"Army 569, seven miles northeast of MINES, cross MINES at 5000 inbound,
cleared VOR/DME Runway 22 approach Rockwood, report procedure turn
inbound."

but I don't think what the pilot did was a deviation from his clearance
as issued.

Chip, I set up that scenario in my CNX80 simulator, to see what IT would =
do.
Indeed, the simulator wants to go once around the holding pattern at =
MINES,
unless I select "Vector to Final", in which case it foregoes the hold.

The same is true even if I set up inbound to MINES on a 240 track.

Since the UH60 pilot asked for the "full" approach, not vectors, I'd =
assume
either that his GPS unit wanted to behave the same as the CNX80,
or else he just needed to log some holding-proficiency time. Maybe =
both.

What the pilot did was correct. A charted course reversal must be flown
unless the pilots receives radar vectors or the route is charted as No PT.
Even if the pilot were perfectly setup for a straight-in at the ideal
altitude, the course reversal is required unless the above criteria area
met.

See AIM 5-4-8:

The procedure turn or hold in lieu of procedure turn is a required maneuver.
The procedure turn is not required when the symbol "No PT" is shown, when
RADAR VECTORING to the final approach course is provided, when conducting a
timed approach, or when the procedure turn is not authorized. The hold in
lieu of procedure turn is not required when RADAR VECTORING to the final
approach course is provided or when "No PT" is shown.

Chip, even if he had been coming in from the northeast, tracking HCH R-060,
he would still have had to turn around at MINES and fly the course reversal,
if he were cleared direct MINES rather than being given Vectors To Final.

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...

Roy, I agree with your phraseology here. Trainee and I tried to discuss
phraseology before he issued the clearance, but we were busy and had a lot
of irons in the fire. One of our problems is that the MINES fix does not
exist on the radar scope- it's not adapted into the ATC computer database.
For the controller, the fix must be interpolated by eyeballing the paper
approach plate, eyeballing the radar scope, and guess-timating about where
MINES really is in space. Because of the computer limitations, the correct
"Seven miles northeast of MINES" phraseology is virtually impossible to come
up with unless ATC is slow enough to make several low priority computer
entries using the slewball/trackball (like a mouse pointer) to pinpoint the
whereabouts of MINES and then the aircraft's relationship to it.

In the event, my guy had his hands full on the other freq and he had his ATC
computer slewball engaged in higher priority duties. I have been hammering
him for weeks about making precise location calls to aircraft, especially on
instrument approaches. Due to his lack of experience with the radar map
display, he can be wildly off when he makes a position call reference a fix.
You may be 15 miles from XXX, and he might tell you "Five miles from XXX,
cleared blah blah blah." Or you could be ten miles out and he tells you "20
miles from XXX, cleared blah blah blah." If I were the pilot on an IAP,
I'd have some serious questions about a ten mile difference in what I showed
to be my position and where ATC just told me I was. In the case of my
trainee, ATC would be wrong quite often, simply because ATC was just tossing
out a figure based on an inexperienced glance at the scope. Because of his
tendency, I have been forcing this developmental to engage his computer
slewball and to make certain involved computer entries to get a fairly
precise position fix before he makes the position call. In the case of
MINES, he couldn't do it easily (quickly) so he used the distance from the
airport instead.

As for the "Report procedure turn inbound", my misunderstanding of this
approach probably led the trainee down the primrose path. The trainee asked
me about the course reversal and I said "I'm not sure...but don't you think
we'd better get higher on that Delta before he smokes the RJ out in front of
him?!?" In other words, I was looking at a higher priority duty when the
question came up. We never got back to the question. The trainee, who is
aggressive, likely said to himself "I'm done asking questions, I need to get
this Army cleared in now and move on. We can discuss the semantics in the
coffee shop later." I believe the trainee knew about the PT but since I
didn't jump on it when he asked me the question, he left the "Report PT" out
of his clearance.

Regards,

Chip, ZTL

Chip brings you out an interesting point about atc advising pilots of
their position.
I've always listened carefully to the atc postiion when they've first
get me on radar, as a cross check to ensure they've got the right
aircraft.
However, when it comes to clearing me for an approach, I've never
really cared to ensure the atc distance is all that close, what with
dual dme's, gps', fms' etc.
Does anyone consider this inappropriate?
After all, the time immediately after being cleared for approach can
be about the busiest, what with changing freqs, final settings to nav
aids, descents, intercepting etc

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

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.

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.

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?

I agree with you.

In addition, Chip should be aware that there are cut-and-dried requirements
in his 7110.65 in order for him to be able to give legal radar vectors to
the FAC so that the pilot will not do the PT. (7110.65 5-9-1)

It does not seem to me as if the requirements were met.






--ron

What the hell, I'll jump in. Just doing a quick search on "full approach",
I didnt find anything relating to the FARS, the AIM, or the 7110.65. If
someone else wants to look through the hundreds of hits, go at it. But
I did find one interesting reference to it in an old AOPA article
http://home.columbus.rr.com/lusch/aopa_article01.html
in part it says...."A pilot training for an instrument rating learns to fly
a full approach* cross the initial approach fix, fly outbound for a minute
or two, execute a procedure turn to get headed the opposite direction, and
fly inbound on the final approach course while descending to decision
altitude or the missed approach point. A full approach is a staple of
instrument flying, yet some pilots rarely, if ever, have to fly one other
than during initial or recurrency/proficiency training. That's because a
full approach usually is required only when radar service is not available,
and radar is available at most larger and busier instrument airports. Pilots
come to expect radar vectors to final approach courses and that ATC will
keep an electronic eye on them all the way to a successful conclusion of
every approach...."

Full approach, which isnt exactly what the pilot said, he said "would like
to shoot the full VOR/DME 22 into Rockwood". This may be splitting hairs,
but he didnt say it (which I'm not convinced there is any such phraseology),
but even if he did, that was a REQUEST, which is not always which is
given by the controller.

I dont think it's so simple that the pilot is expected to do a PT.
On procedure turns, the AIM, as earlier stated does indeed say....
5-4-9. Procedure Turn

a. A procedure turn is the maneuver prescribed when it is necessary to
perform a course reversal to establish the aircraft inbound on an
intermediate or final approach course. The procedure turn or hold in lieu of
procedure turn is a required maneuver.

First off, as we are reminded quite often, the AIM is not regulatory.
Secondly,
if you read that verbatim, it says "when it is necessary". Giving someone
a vector, or this clearance where it's within 30 degrees or so, basically a
straight-in to the IAF, I do not consider the PT "necessary". You can't
tell
me that a course reversal on damn near a straight-in could ever be mistaken
in court as "necessary" for the establishment of this intermediate part of
the approach, UNLESS the airplane is way too high, which in this case is
not applicable as the altitude was good and in accordance with the IAP.

Also in 5-4-9a5 "A procedure turn is not required when an approach can be
made directly from a specified intermediate fix to the final approach fix. "
Is MINES an intermediate fix? It's not the FAF, it is an IAF, can it also
be an intermediate fix in the context of this clearance which includes a
non-published route prior to it? Tough to say.

Lastly on 5-4-9b1 "In the case of a radar initial approach to a final
approach fix or position, or a timed approach from a holding fix, or where
the procedure specifies NoPT, no pilot may make a procedure turn unless,
when final approach clearance is received, the pilot so advises ATC and a
clearance is received to execute a procedure turn."

This is the one the FAA, if it so chose, could go after the pilot. They
would
argue that the non-published route (direct MINES) was in essense a
RADAR VECTOR. This particular clearance can only be done with
radar service provided. This is not an arc, a victor airway, or a published
transition. That's why it was correctly included in the clearance that the
pilot should cross MINES at 5,000', which is above the MIA (Minimum
IFR Altitude) and keeps him in radar contact. The clearance also included
(which is also phraseology I'm not sure exists) "cross MINES at 5000
INBOUND". That "inbound" I'm not so sure of, and could cause confusion
with the pilot. It could mean hit MINES and continue inbound, no PT, or
it could mean once he's inbound, cross MINES at 5,000'.

There was confusion on both sides here, the way I see it. The pilot made
his REQUEST, figures he got what he asked for. The controller heard
the request, used questionable phraseology to get what he wanted to get
across, and the end result was the pilot doing something other than the
controller expected. "Report PT inbound" wouldve probably made it
real clear, and if the pilot didnt intend on doing a PT, that would have
raised a warning flag to him. I guess you can ask if he's going to do
the course reversal, and if I hear "full approach", I'd at the very least
protect the airspace either way, or just ask the pilot.

You ask any controller, or Airspace & Procedures specialist this
situation, you'll get lots of different interpretations. They'll all
probably agree that the communication was hazy (you didnt
"break the chain" as they love to shove down our throats), and
the pilot may have been a little guilty of hearing what he wanted
to hear - although we dont have the exact tapes. A REQUEST
means nothing without a CLEARANCE. I'd be interested in
hearing the pilots readback, I'm willing to bet that it wasn't
exactly standard phraseology either.

But the FARs are:

FAR 91.175

(j) Limitation on procedure turns. In the case of a radar vector to a final
approach course or fix, a timed approach from a holding fix, or an approach
for which the procedure specifies "No PT," no pilot may make a procedure
turn unless cleared to do so by ATC.


OK, a second point.
A radar vector is a heading to fly. A clearance to a fix is not a vector,
it specifies a specific point to fly to.
A vector to final will be a heading to fly (the vector) followed by an
instruction to join the final approach course.

No, but Part 97 is, and prescribes a mandatory procedure turn for that
approach unless one of the exceptions in Part 91 is met.

And none of them were met.

The 7110.65 requirements for issuing radar vectors to a final approach
course were also not met.

Subpart (i) right above that starts touching on unpublished routes, but
seems
to mostly talk about altitudes to maintain, not routes to fly. You could
say
that (j) above covers that, but it doesnt talk about unpublished routes.
The
only way I could see the whole issue perfectly cleared up is if they added
in (j) "on an unpublished route within XX degrees of the
intermediate or final approach course", but it doesnt. It is a vague area
between (i) and (j) and the AIMS 5-4-9a5 (PT not required when...).
(j) is the only place in 91.175 where PT's are mentioned. Regs and
our 7110.65 seem often to be written in the negative, like this one where
it says when you CANT do a PT. I'd be sweating in court as a pilot
trying to dig a positive statement that I COULD do one in that limited
paragraph.

In 7110.65 5-6-2e METHODS, and this is a clearance we give daily
whether the airplane is GPS/FMS/RNAV or not....
FLY HEADING (degrees). WHEN ABLE, PROCEED
DIRECT (name of fix),
That above is a vector, it is also a specific point to fly to, and a
perfectly legitimate clearance. So are you saying if he said the
above, a PT would NOT be authorized because of 91.175, yet
it would be authorized if it was MINUS "fly heading"?

And you can be vectored to a radial outside the IAF, and not just
direct to the IAF. Many times I get that request so they can set
up and established a little before the IAF. So vectors are not just
for the FAC.

Regardless, I still dont see the "necessary" part of the PT in this
scenario. Ya, I know that's only in the AIM, but how would you
be able to defend that part if you were set up a mile outside of
the IAF on the radial, or 10 miles, or 100 miles out. I can easily
see an FAA attorney using this argument.

I wasn't vectoring to the FAC. I do not/cannot/would not vector to the FAC
at this airport anyway because nothing of this approach is depicted on the
radar scope except for the airport. None of the fixes on the approach even
exist in the ATC database. I had no intention of vectoring for the FAC. My
mistake was in misunderstanding the procedure.

Interesting discussion, since in my view the answer is cut-and-dried and
unequivocal: vector-to-final or "NoPT" => no procedure turn, otherwise =>
procedure turn.

I've also found that some controllers seem surprised by this, so I make a point
of informally making sure the controller and I have the same expectations, but
from a legal point of view, the answer is clear.

BTW, I don't see where the controller has discretion to waive the requirement
for a procedure turn, either, as they sometimes want to do. Seems to me if the
controller doesn't want me to do a PT, they need to either put me on a NoPT
segment or give me vectors to final. If I'm navigating on my own to the IAF, I'm
going to do the PT.

This brings me back to something you mentioned in your original post,
that got my attention. You said:

How does this work? Can two facilities really swap airspace back and
forth between themselves with something as informal as a phone call?
There's a reason I ask...

A while back, I was flying into MMK (Meriden, CT) on a training flight
with a student. We were IFR, conditions were night, but clear skies.
The approach chart says Bradley Approach runs the approach control, but
my experience has been that radio contact with Bradley is usually pretty
poor. MMK is right on the edge between Bradley and New York Approach.
That night was no exception, and we lost contact completely with Bradley
while on a vector downwind. This was actually a good thing, because it
gave me the opportunity to hold an impromptu lesson on lost comm
procedures.

We tried calling Bradley a few times, and then got a message relayed by
another flight in the area to call Bradley on a different freq. No joy
on that freq either, and by that time we were out of radio contact with
the other aircraft. I decided to try one more trick and punch up
"Nearest ARTCC" on the GPS. Wonderful feature, that. It put us in
contact with Boston Center, loud and clear. It took just a moment to
explain the situation to the center guy, and he quickly got us a new
freq for NY Approach (by now we were probably pretty deep into NY's
airspace).

I expected the NY controller would give us vectors back towards MMK and
then hand us off to Bradley again, but that's not what happened. To my
surprise, he gave us vectors to final, cleared us for the approach, and
issued instructions to contact Bradley on the missed (the missed takes
you deeper into Bradley territory and radio comm is usually much better
on that side of the airport). We flew the approach, called Bradley on
the missed, and the controller acted like nothing strange had happened.

So, could you fill me in on what was happening behind the scenes? Once
I went lost comm, how did ATC deal with that? Did the Bradley guy just
hand me off to NY when he saw me leaving his airspace? And, most
interesting to me, how was the NY controller able to clear us for an
approach to an airport that he didn't own?

The trainee and I did discuss where the "full approach" began. Since we
rarely work aircraft approaching RKW from the east, it was a legitimate
question in my mind. We had literally about 20 seconds to huddle with the
plate during the OJTI. We had our hands full with higher priority ATC stuff
and airplanes were calling right and left. This aircraft had GPS, so I said
I though the full approach in this case begins at the IAF (MINES) and we
could clear him to MINES via GPS-direct. The trainee thought that the
"full" approach began at HCH Vor, and involved flying out on the 060R to get
to MINES, then doing a course reversal. He asked if he should clear the guy
to HCH to start the full approach. HCH was 30 miles west of the position
from which the approach request was made and would have involved a serious
detour.

Now I'm wondering what I could have done with this UH-60 if it had been a /A
instead of a /G. We don't clear /A's direct to intersections. Where does
the "full approach" begin for a non-RNAV on this procedure. I can't vector
to final at this location.

The direction from which the aircraft was approaching MINES likely
contributed to my misunderstanding. He was approaching MINES on a track
that intercepted the FAC at 30 degrees or less. The VOR/DME Rwy22 is also
the GPS Rwy 22. I got it in my head that he didn't need a PT. What the
heck, on many of the newer GPS approaches, aircraft make 90 degree turns
between waypoints to get to the FAF. I had the wrong site picture here.

I believe that the phraseology "inbound" slipped in there because we have an
approach to another airport where this is required phraseology. He had
issued this other clearance earier in the session. My Dev only has about 60
hours on this position, working on his first two R-sides.

Yeah, we were protecting the airspace anyway. I didn't really have my radio
to use, so I didn't ask like I normally would.

The phraseology that I wrote for the ATC side of things is 100% accurate for
the event, but not 100% correct by the book. The Army pilot was
transmitting on UHF, so even if we could pull voice tapes, we'd likely not
fully understand him. Our UHF receivers are old, worn out and often
unservicable. His initial request was stepped on by an air carrier on VHF
in our other combined sector asking about the freaking ride. (Jeeze is
*that* is getting OLD!!!). His subsequent request was hard to understand,
but he did emphasize a request for the *full* approach.

I'd love to find an Airspace and Procedures guy anywhere in my Region who
had a clue to begin with. Down here in ZTL, we have a total disconnect
between the guys maintaining procedures for the facility, the guys
publishing new procedures up at the Regional level (Terps guys) and the men
and women keying the mic at the sector. For example, GPS approaches are
dropping into my airspace like landmines. We don't get briefed on the
changes anymore. Heck they aren't even "read and initial" items these days,
likely because the 530 guy doesn't even know about them. They even change
things like a missed approach procedure and the only way you can spot it is
by reading the paper IAP plate before issuing the clearance. They plop new
approaches in the airspace and you discover them when the pilot requests the
procedure and you scramble for the plate. We are so short staffed right now
at ZTL, we don't even do crew/team training anymore. I haven't had a Team
Training in three years. Everyone is months behind on CBI's. Our facility
Airspace office doesn't even pretend to try anymore. Yall are probably the
same way out there- it's getting pretty bad all over the Enroute community.

Thanks for the insight.

The general answer to where a full approach can begin is "any fix that's marked
IAF on the approach chart". For this approach, the only IAF is MINES. So for a
non-RNAV aircraft, I'd think the only way to give a non-RNAV the full approach
would be to send him to HCH and let him navigate himself to MINES, or give him a
vector to the radial and let him navigate to MINES.

If I heard "cleared to MINES via heading <x>, join the HCH 060 radial and track
it inbound (or outbound), cross MINES at or above 5000, cleared for the
approach", I would do the PT.

On the other hand if I heard "fly heading <x>, vectors for the final approach
course, maintain 5000 until MINES, cleared for the approach", I would not do the PT.

On the third hand, if I thought there was any confusion about whether a PT would
be done, I'd tell ATC what my plans were.

I don't have an en-route chart of the area, just the approach plate off
the net, so I may be missing something. The only legal way I see to fly
this approach pilot nav and /A is "Direct Hinch Mountain, Hinch Mountain
060 radial, MINES, cross MINES at or above 5000, cleared VOR/DME 22
approach". It's about 60 miles out of the way, but them's the breaks.
Hope he planned on that when he fueled up for the flight.

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.

Chip, I'm honestly not trying to be a pain, but while the question was
a legitimate one in your mind, it wasn't legitimate regulatorily. In
other words, I think the source of the confusion is a less-than-ideal
understanding of the applicable rules. Don't feel too bad - I just
saw the same level of understanding in a 1500+ hour multi/IFR pilot I
flew with recently.

The full approach ALWAYS begins at the IAF (or an IAF if there is more
than one) regardless of how the aircraft is equipped.

> and we could clear him to MINES via GPS-direct.

There's the difference. Since the aircraft had RNAV (not necessarily
GPS - any kind of approved RNAV would be fine, since the approach does
not start until the IAF is crossed) you could clear him direct to
MINES. Without RNAV, you would need an alternate plan.

Well, he was wrong - but as a trainee he has every right to be wrong.

I'm pretty sure you can vector an aircraft to intercept an airway -
can you do the same for a random VOR radial? How about "Fly heading
XXX, intercept the HCH-060 radial, track the radial to MINES, cleared
for the full approach, report procedure turn inbound?"

I understand.

But others have brought that up that possibility in this thread and I
thought it worthwhile that the point be absolutely clear to everyone (not

FAAO 8260.19 requires any arcs in a radar environment to be removed
unless they are operationally required. It appears that someone deemed
that they were not needed back in 1992, when they were removed from the
procedure. GPS was overlayed later, so had nothing to do with removal of
the arcs.
The arcs probably had the annotation "NoPT" on them, since a course
reversal would not have been required from the arcs based on the TERPS
criteria in effect back in 1992.
An interesting point that might help ATC understand the PT/NoPT question
is that anytime a route is published that allows elimination of the
course reversal, then the procedure specialist must indicate that by
publishing "NoPT" on that route segment. Otherwise, the PT is expected.
Since ATC was substituting radar flight following (not vectors) combined
with center's MIA to protect the GPS equipped aircraft on his flight to
MINES, then it would be up to ATC to indicate that the course reversal
was not necessary by stating that to the pilot.
In the case of the UH-60, though, once he asked for the "full approach"
it would have alerted me that he wanted a little more than a quick
straight-in, and I would have queried him further to confirm exactly
what he wanted, (hold-in lieu, clearance to Hinch Mountain for the
feeder, or what?).
We used to routinely vector military aircraft to intercept the final,
but whenever one requested the full procedure, that was our clue to
clear them via non-radar routes to the IAF, even if it was 20 miles
further out.

Chip, there's a web
