I'm wondering if the NACO chart shows the barb at EXUPY as a
*recommended*
PT commencement point, because one can initiate a nice three degree
stabilized descent from there.

According to what others have written in the past, it is there only for
charting convenience. In other words, whoever designed the chart thought
things would look less cluttered that way.


Yes, it could have been purely for that reason. However, it seems that the
PT barb could have easily been shown inside 10 DME without clutter. And it
is interesting that EXUPY is the point at which a three degree descent would
begin to the VOR, and that invites speculation as to coincidence or intent.
One could do worse than choosing EXUPY as a point for initiating the PT.
Coming in from IAF KIKII, one would begin descent from 3600 at EXUPY, and a
stabilized 3 degree descent could be made all the way to the airport from
there, and it seems possible that the charting person chose to show the PT
barb outside EXUPY, on the 3600 ft segment, as a suggestion to the pilot as
to where to execute the PT. Since s/he has the discretion.....

I don't use NACO charts so that's why I ask these questions:

Do you have any documentation to indicate that the location of barb
placement on a NACO chart is determined by this method?

Is it a standard for NACO charts that the barb is placed at the 3° descent
point?
