Not only are circling minimums
NA for Cat C and D, but so are straight-in mins.
There is no free lunch, of course, so remember that the new circling criteria expand the area of protected airspace, generally, by raising circling minimums

You can call up an approach chart without fear (or guilt) that maybe the circling minimums

In other words, a straight-in procedure is authorized, but you must use the higher circling minimums
They have only circling minimums

Some will restrict themselves to taking off only when circling minimums

Good to know, even accepting that's 1200 feet above the runway, or a 24-degree descent angle to land straight in, and it's 600 feet above circling minimums
In a circle-to-land maneuver, you must maintain circling minimums
until you are in a position to make a normal rate of descent to the touchdown point.
Add departure minimums like, "Departure ceilings and visibility must be at or above circling minimums
for an available approach.
Many current RNAV approaches list several different sets of minimums, including circling minimums
, and an "LNAV MDA," as if you were using GPS in lieu of a localizer on a non-precision approach.
