Sectional Chart Question

IIRC, The yellow represents areas under the FAR's which are
considered congested areas and require 1000' clearance within a 2000'
radius.


From what do you recall that?

Well no. Don't think you can find any legal reference to support your
claim. If you compare the yellow on a sectional and a terminal area chart
they don't match.

On a sectional chart, around cities, are yellow areas.
What are they?
Where on the legend can this be found?


"From the Ground Up" P:177

Communities, Roads, Railways
Yellow squares represent towns and small villages. Hamlets are
represented by small circles. A city is depicted by a yellow area
outlined in black that corresponds to the actual shape and size of the
community.

Amazing. Nobody ever told me that!

What would we do with newsgroups to consume our time and fill our
minds with facts?

Useful pointer--thanks!

Note though that it refers to "populated" places, not "congested" places.
"Congested" has technical meaning in the FARs (regarding altitude rules),
and it's not clear whether "populated" means the same thing.

It doesn't. According to the local FAA, the beaches around here are congested
areas during the summer season. They aren't congested in the winter. Sandy Hook
during summer is an example of an unpopulated congested area.

Good point. I wonder though about the converse--are populated areas always
considered congested, or can there be (sparsely) populated areas that are
considered uncongested?

Yes ... I meant Populated, not congested.
Thanks for catching that.

Well, the purpose of the detail on the chart is to provide visual cues
as to your location with respect to the populated area. Not (as far as
I know) to determine whether or not you are over a "congested" area.

However, when I was flying ultralights (which cannot be flown over
congested areas at all), my instructor would not let me fly over areas
depicted as populated on the sectional. I think he was going overboard,
but as a training rule, it was fine.

From what I've seen/read, what is or is not a congested area is not
defined well. Perhaps there are some 'legal interpretations' out there
that I've not seen yet.

Note that you will not find a definition of "congested" in any FAA
document. It is deliberately undefined to allow for broadly varying
enforcement.
