Subpart A—General
§ 73.1
Applicability.
The airspace that is described in sub-
part B and subpart C of this part is des-
ignated as special use airspace. These
parts prescribe the requirements for
the use of that airspace.
§ 73.3
Special use airspace.
(a) Special use airspace consists of
airspace of defined dimensions identi-
fied by an area on the surface of the
earth wherein activities must be con-
fined because of their nature, or where-
in limitations are imposed upon air-
craft operations that are not a part of
those activities, or both.
(b) The vertical limits of special use
airspace are measured by designated
altitude floors and ceilings expressed
as flight levels or as feet above mean
sea level. Unless otherwise specified,
the word ‘‘to’’ (an altitude or flight
level) means ‘‘to and including’’ (that
altitude or flight level).
(c) The horizontal limits of special
use airspace are measured by bound-
aries described by geographic coordi-
nates or other appropriate references
that clearly define their perimeter.
(d) The period of time during which a
designation of special use airspace is in
effect is stated in the designation.
§ 73.5
Bearings; radials; miles.
(a) All bearings and radials in this
part are true from point of origin.
(b) Unless otherwise specified, all
mileages in this part are stated as stat-
ute miles.
Subpart B—Restricted Areas
§ 73.11
Applicability.
This subpart designates restricted
areas and prescribes limitations on the
operation of aircraft within them.
§ 73.13
Restrictions.
No person may operate an aircraft
within a restricted area between the
designated altitudes and during the
time of designation, unless he has the
advance permission of
(a) The using agency described in
§ 73.15; or
(b) The controlling agency described
in § 73.17.
§ 73.15
Using agency.
(a) For the purposes of this subpart,
the following are using agencies;
(1) The agency, organization, or mili-
tary command whose activity within a
restricted area necessitated the area
being so designated.

14 CFR Ch. I (1–1–24 Edition)
§ 73.17
(b) Upon the request of the FAA, the
using agency shall execute a letter es-
tablishing procedures for joint use of a
restricted area by the using agency and
the controlling agency, under which
the using agency would notify the con-
trolling agency whenever the control-
ling agency may grant permission for
transit through the restricted area in
accordance with the terms of the let-
ter.
(c) The using agency shall—
(1) Schedule activities within the re-
stricted area;
(2) Authorize transit through, or
flight within, the restricted area as
feasible; and
(3) Contain within the restricted area
all activities conducted therein in ac-
cordance with the purpose for which it
was designated.
§ 73.17
Controlling agency.
For the purposes of this part, the
controlling agency is the FAA facility
that may authorize transit through or
flight within a restricted area in ac-
cordance with a joint-use letter issued
under § 73.15.
§ 73.19
Reports by using agency.
(a) Each using agency must prepare a
report on the use of each restricted
area assigned thereto during any part
of the preceding 12-month period ended
September 30, and transmit it by the
following January 31 of each year to
the Manager, Operations Support
Group in the ATO Service Center office
of the Federal Aviation Administration
having jurisdiction over the area in
which the restricted area is located,
with a copy to the Manager, Airspace
Policy Group, Federal Aviation Admin-
istration, 800 Independence Avenue SW,
Washington, DC 20591.
(b) In the report under this section
the using agency must:
(1) State the name and number of the
restricted area as published in this
part, and the period covered by the re-
port.
(2) State the activities (including av-
erage daily number of operations if ap-
propriate) conducted in the area, and
any other pertinent information con-
cerning current and future electronic
monitoring devices.
(3) State the number of hours daily,
the days of the week, and the number
of weeks during the year that the area
was used.
(4) For restricted areas having a
joint-use designation, also state the
number of hours daily, the days of the
week, and the number of weeks during
the year that the restricted area was
released to the controlling agency for
public use.
(5) State the mean sea level altitudes
or flight levels (whichever is appro-
priate) used in aircraft operations and
the maximum and average ordinate of
surface firing (expressed in feet, mean
sea level altitude) used on a daily,
weekly, and yearly basis.
(6) Include a chart of the area (of op-
tional scale and design) depicting, if
used, aircraft operating areas, flight
patterns, ordnance delivery areas, sur-
face firing points, and target, fan, and
impact areas. After once submitting an
appropriate chart, subsequent annual
charts are not required unless there is
a change in the area, activity or alti-
tude (or flight levels) used, which
might alter the depiction of the activi-
ties originally reported. If no change is
to be submitted, a statement indi-
cating ‘‘no change’’ shall be included in
the report.
(7) Include any other information not
otherwise required under this part
which is considered pertinent to activi-
ties carried on in the restricted area.
(c) If it is determined that the infor-
mation submitted under paragraph (b)
of this section is not sufficient to
evaluate the nature and extent of the
use of a restricted area, the FAA may
request the using agency to submit
supplementary reports. Within 60 days
after receiving a request for additional
information, the using agency must
submit such information as the FAA
Service Center Operations Support
Group Manager considers appropriate.
Supplementary reports must be sent to
