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
