Many thanks.

Because of the clutter and close proximity of the three airports, this
is not an easy chart to read. I presume the thick, blue, slashed,
concentric circles centered on El Toro depict the Class C airspace,
and the thinner blue dashed 'keyhole' shaped circle centered on El
Toro depicts its Control Zone much the same as Class D airspace is
currently depicted on current charts. The wedge shaped area south of
El Toro refereed to in the Special Notice, doesn't appear to be
depicted as Class D nor part of the CZ, as it isn't bounded by the
typical Class D boundary depiction. However, it is effectively Class
D, as it is necessary to contact ATC (the tower?) to operate within
it.

So when you said:

El Toro MCAS used to have Class D airspace adjacent to the Class C
airspace that didn't even reach the surface.

was it the Special Notice airspace to which you were referring?


Did you download both charts? They were uploaded separately due to their
size.

Airspace reclassification happened in 1993. The 1987 chart depicts the El
Toro ARSA which became the El Toro Class C and is depicted on the 1997
chart. The area of concern is south of the MCAS, it overlies Dana Point and
extends to the north to abut and underlie the El Toro ARSA/Class C. On the
1987 chart it is designated "MCAS El Toro Special Air Traffic Rules", see
the bold blue arrow at the bottom left of the image. On the 1997 chart it
is designated Class D airspace, see the not quite as bold blue arrow in a
similar position.
