Why do you suppose they charted this with redundant names and flags?

You would be surprised how much harder it is to take something off an existing chart, than to add the new improved depiction. They quit half done.:oops:
 
Odd. I was going to say it was a software mosaicking two charts together (this is usually when you see this), but this seems double printed on the raw Charlotte sectional. At least they put the same information in both blocks.

Anyhow, it's a mistake. I reported it.

Well, today I learned something (and I thought there was darned little I didn't know about charting as I started on this years before I became a pilot):

Thank you for your inquiry regarding the labels and flag symbol for SUT (Cape Fear Regional Jetport) on the Charlotte Sectional Chart. The reason for the duplicate labels is due to the way that the paper copies of the charts are folded horizontally. In the area of the fold between the "front" and "back" of the sectional, data will be shown twice. This is done purposefully so that the paper copy, when fully open, does not have to be flipped back and forth, and so that pertinent information in the fold area can be easily seen and not missed. Digital copies of the charts do not need, nor show, the area of the fold that would be needed for a paper copy, and it can end up looking like some items are printed twice.

It took me a moment to figure out what they meant by "fold" and that it means (in my mind) the frontside/backside cut.

But in any case, I did some scrolling around and found Blythe (BLH) to be another example, minus the 2 flags...

What’s the point? Once you unfolded them you could never get the folded back up. :)
It's not a fold, it's actually a cut. The northern half of SUT (or BLH) would be on the front side of the paper chart and the southern half on the back side of the paper chart. Supposing only the label on the northern side of the airport were printed, you wouldn't be able to read the information if you were looking at the back side of the chart which only has the southern half of the airport.
 
That is CFI GOLD right there!

For a long time there was a NDB called INSTITUTE in downtown Baltimore. I figured it had to be on the UMAB campus somewhere. Years later when I was touring Shock Trauma with the local fire department, we walked into their comm center and I found the transmitter sitting on top of one of the cabinets. So that's where it is, I said.
