The purpose of the "R" is to denote airports that have ASR but that do not
fit into any of the categories you noted, which would have ASR by default.
It indicates the existence of ASR at locations where there would be no other
indication to a pilot that it existed.

You're wrong; go look at the legend on a Sectional and review
the AIM.


No, I'm not wrong. Every airport with Class B or Class C airspace or a
TRSA
has ASR. Hell, the reason they're established is to provide radar
services,
how could they do that without radar? There's no need for the little blue
R
at these airports because the presence of Class B or Class C airspace or a
TRSA indicates they have ASR, the R would be superfluous.



This subject is of zero importance to me; I have no interest in
discussing
it with you further.


If it had no importance to you why'd you join the discussion?
