"Movement Area" (airplanes and trucks)

There are "taxiways" and there are "taxiways".


So how do "taxiways" differ from "taxiways"?



What matters is how the
airport operator has defined the non-movement areas. You can easily see
that from the markings on the pavement, or of course you could ask the
controllers or other officials at the airport. Just because a person
might use the word "taxiway" to describe an area on the airport, that
doesn't mean it's subject to the regulation that was quoted.


Why not?



Regardless, there are examples of places where taxiways (that is, long
stretches of pavement on which aircraft are expected to taxi) are simply
not part of the movement area, and are not subject to the regulation that
was quoted.


How does the regulation that was quoted differentiate between those
taxiways?



If it were true that one could not operate an aircraft on a taxiway that
is within a non-movement area without an ATC clearance, then thousands of
pilots each day would be in violation of that regulation. I personally
don't believe that's the case, so through proof by contradiction, the
regulation doesn't apply to taxiways that are within a non-movement area.


If the posted speed limit is 70, but the state patrol doesn't issue speeding
citations for less than 75, is the speed limit then 75?



If someone has some compelling evidence to suggest that these thousands of
pilots ARE violating the regulation, and can explain how that could be and
yet the FAA doesn't seem interested in citing any of those pilots, that
might be an interesting topic. But I doubt such evidence will be
forthcoming.


They're violating the letter of the law, no evidence beyond that is needed.

One kind is in movement areas, the other kind is not.

Why not?

Non-movement areas are defined as not being under ATC control. How would
ATC issue a legal clearance to aircraft operating only within the
non-movement area? By definition, being in a non-movement area means you
are not under ATC control.

taxiways?

It doesn't.

No, it's not.

You have no evidence that they are violating the letter of the law.

I assume it has signage and markings consistent with other taxiways at

Yes.

Any idea why taxiway H is not on the airport diagram?

None. FYI: Up until about a year or two ago, it wasn't a taxiway. It had
no official name. People called P "outer" and what-is-now-H "inner" (I
might have reversed these).



It's the parking area near the east side of 9-27.


Why is it called RN tiedown?

No idea. There's a story that the taxiway and ramp areas were named by one
individual with fits of odd creativity. Taxiway T, for example, is so
named (according to this story) because of its proximity to the tower.

The bravo tiedown is along side of taxiway B. The delta ramp is near
taxiway delta. RN is reached via taxiway N...but that leave the R part of
the name something of a mystery.

Perhaps another CDW-dweller here knows the answer?

Clearly, at least with respect to that regulation, those "taxiways" are

(including being called a "taxiway" by ATC).

This is giving me what I'll choose to call a headache, even if it is similar
to every other headache but for the differences between this headache and
all headaches.

In your case at KCDW, the important question is whether the boundary of
the non-movement area is clearly marked on the pavement.Â*Â*IÂ*don'tÂ*know
whether it is or not; I suspect that because ATC treats it as a
non-movement area, that it is so marked, but it's possible that it's not.

I'm not sure; I'll have to look.

I was under the impression that taxiways had to be named in the order in
which they appear going around a clock face (and they all had to be
renamed if a new taxiway was added).

Any idea why that was considered a good idea?
