Class B and Class C are not special-use airspaces:

SPECIAL USE AIRSPACE- Airspace of defined
dimensions identified by an area on the surface of the
earth wherein activities must be confined because of
their nature and/or wherein limitations may be
imposed upon aircraft operations that are not a part of
those activities. Types of special use airspace a

a. Alert Area- Airspace which may contain a high
volume of pilot training activities or an unusual type
of aerial activity, neither of which is hazardous to
aircraft. Alert Areas are depicted on aeronautical
charts for the information of nonparticipating pilots.
All activities within an Alert Area are conducted in
accordance with Federal Aviation Regulations, and
pilots of participating aircraft as well as pilots
transiting the area are equally responsible for collision
avoidance.

b. Controlled Firing Area- Airspace wherein
activities are conducted under conditions so controlled
as to eliminate hazards to nonparticipating
aircraft and to ensure the safety of persons and
property on the ground.

c. Military Operations Area (MOA)- A MOA is
airspace established outside of Class A airspace area
to separate or segregate certain nonhazardous military
activities from IFR traffic and to identify for
VFR traffic where these activities are conducted.

d. Prohibited Area- Airspace designated under
14 CFR Part 73 within which no person may operate
an aircraft without the permission of the using
agency.

e. Restricted Area- Airspace designated under
14 CFR Part 73, within which the flight of aircraft,
while not wholly prohibited, is subject to restriction.
Most restricted areas are designated joint use and
IFR/VFR operations in the area may be authorized by
the controlling ATC facility when it is not being
utilized by the using agency. Restricted areas are
depicted on en route charts. Where joint use is
authorized, the name of the ATC controlling facility
is also shown.

f. Warning Area- A warning area is airspace of
defined dimensions extending from 3 nautical miles
outward from the coast of the United States, that
contains activity that may be hazardous to nonparticipating
aircraft. The purpose of such warning area is
to warn nonparticipating pilots of the potential
danger. A warning area may be located over domestic
or international waters or both.
