Congrats on getting your ticket. IMC flying is the best part of flying to
me.
Your examiner is right. Your problem with understanding this situation is
conceptual I think. A circle to land manuever is a visual procedure and
circling procedures and techniques aren't compatible with precision
approaches and DHs. On a precision approach, you're descending until a
specified decision height. The theory is at that height you make a decision
to go missed or continue straight ahead with the approach to landing.
You'll note that DHs are much lower in nearly all cases than MDAs and that's
why you either see the rwy and land or you go missed. Not so with an MDA
where you level off and drive in to the MAP. You'd be cutting yourself out
of a lot of time to search for the rwy if you treated the Circling MDA as a
DH.
On a circle to land, you're flying an IAP to do a visual manuever to another
rwy. The theory is to descend to the minimum obstruction clearance altitude
(Circling MDA) and drive toward the airport while looking for the runway
environment. If you don't have it by the MAP, you aren't going to have it
on that pass and you must go missed. I searched the CFR/AIM for a reference
and didn't find one. The reference for the above is found in AF Manual
11-217, Instrument Flight Procedures.

Well, first of all, there is no such thing as "circle-to-land" DH.
Presumably, you mean MDA.
You can remain at the MDA until you reach the MAP. Wht you are
describing, unless I am missing something, is an old-fashioned
localizer approach.
One word of caution, there are a few ILS IAPs in mountainous areas that
require descent on the G/S, even for circling, but that is noted on the
chart. Also, there are some ILS IAPs that do not have circling minimums
but, again, that is apparent from the chart. Finally, there are some ILS
IAPs where the non-precision (LOC) MAP is prior to the runway threshold.
The non-precision MAP is always the "do not pass" line for continuing the
approach without the required visual references. And, the required
visual references for circling are quite permissive; only the airport
must be in sight. But, before you can descend below the circling MDA to
land on any authorized runway, then the visual reference requirements are
the same as they are for straight-in.
Another thing that is often missed by new instrument pilots is that
circling is sometimes restricted to a portion of the circling maneuvering
area. This is noted on the IAP chart, but is very difficult to visualize
on the fly; it is best to understand such restrictions before using the
approach.

Circle-to-land is not a precision approach, but if conducted on an IAP with
the title "ILS," it certainly *is* an ILS approach.

I guess the difference in our responses to this new instrument pilot is
that I actually tried to be helpful rather than confrontational.
So you're a failure and imperceptive as well.

Well, that's an interesting point. Is there any reason I can't track the
GS down to the circling MDA, or do I need to follow the LOC descent
profile, which may have stepdown fixes. Given a choice, I'd much rather
track the GS (especially if I had an A/P which could do coupled approaches).

I have seen some ILS approaches (no I'm not going to spend time digging for

If the plate says ILS you should be cleared for an ILS.

That is not correct. ATC must clear you by the name of the approach on the
chart. Only when the chart says "LOC" can you be cleared for a localizer
approach.

You are. It is your call to follow the G/S or the non-precision profile,
stopping descent in both cases at the circling MDA if you intend to circle.
Folks seem to be confusing ILS with precision approach, which it is only when
flown to DH/A for a straight-in landing.

Did I say anything to the contrary? When cleared for an ILS approach you can
fly the non-precision or precision approach at your election.
As to circling minimums, I don't follow you. Most, but not all, ILS approach
charts have circling minimums.
Actually, it is both.

Aren't depicted? What do you mean by that? Most approaches have circling
minima, quite a few have only circling minima, but I've never seen one which
had any specific circling maneuver depicted on the chart.
No. The reason you can't shoot a circling approach is because ATC didn't
clear you for the circling approach.
Depiction (or lack thereof), has nothing to do with it.

ATC may give circling approach instructions only at airports with operating
control towers. At uncontrolled fields you are free to circle as you see
fit, ATC will not clear you for a circling approach, and ATC cannot prevent
you from making a circling approach.
Well, ATC can assign you a circling approach as well.

The reason they don't depict a circling approach is because the
"pattern" is left up to the pilot. He may draw it out in his head anyway
he wants, as long as he complies with any ATC instrucion or local
pattern requirement, and any notes published on the approach plate.
Absent an emergency.

BS. At an uncontrolled field, ATC has NO IDEA what the weather is. They clear
you for the approach (FDK ILS 23 for example) and you as the PIC determine
which runway you will land on. If the winds favor another runway, you
descend down to circling MDA, and then press on and circle.
At a controlled field, approach may clear you for the ILS, and then the Tower
may clear you to circle. Happens ALL the time here at DCA.

Not true, lots of uncontrolled fields have weather reporting.
I know the fields with an FSS do, but there are few of them anymore.
Are you talking about the automated equipment?

Yup. At many of those fields with FSSs the weather observation is automated
as well.

You are correct but many do not. Anyway, the point was that ATC does not
assign circle-to-land at uncontrolled fields unless the runway served by the
ILS is closed.

Now this is a BS statement.
Yes, but you said "At an uncontrolled field, ATC has NO IDEA what the
weather is." At many uncontrolled fields ATC has a very good idea what the
weather is.

OK, I agree then that saying the controller has "no idea" of the weather
would be an overstatement, however, the AWOS/ASOS equipment has some
pretty severe limitations. Last I knew it only looked essentially
straight up and had a few other limitations. Also, it seems like they
are "OOS" way too frequently. Still hard to beat a human on the ground
for good weather.

We are saying the same thing. Also, if the approach is to an airport without an
operating control tower, no further clearance is needed to circle, if that is
what you need to do.
Norm Melick wrote:

When cleared for an approach that has circiling minimums those minimums are
available to you if you need or elect to use them. At airports with operating
control towers you need the concurrence of the tower to circle. But, at an
airport without an operating control tower (which is the majority of airports with
IAPs), ATC has no jurisdiction whatsover over whether you elect to circle-to-land.

I presume you mean by "the circiling approach isn't depicted because you have
to request it" to mean an approach chart that does not have circling minimums.
In that case you cannot circle because there are no circling minmums and AVN
has not evaluated the circling area for obstacles. Approaches without circling
minimums are typically at major airports where every runway end has a
straight-in IAP.
Without published circling minimums ATC cannot create them out of thin air.
The authorizations and protections of an approach chart are a flight operations
"contract" between you and the FAA Flight Standards Service, not ATC. ATC
determines, based on airspace availability, whether you will be granted an air
traffic clearance to use a given approach procedure.

It distresses me that he seems to enjoy attacking people and engaging in
name-calling. We know that he is a working air traffic controller. Whether he
likes it or not, once so identified he represents the FAA, indirectly at
least. It's like someone signing on here and saying "I am a captain for
Skyblast Airlines" then goes on to conduct himself like SM. It wouldn't
reflect too well on Skyblast Airlines.
