mounted transponder antenna (required for TCAS II

installations) will be better received by SBA, especially at latitudes
below 45 degrees.

SPACE LAUNCH AND REENTRY AREA

-

 Locations where commercial space launch and/or reentry

operations occur. For pilot awareness, a rocket

-

shaped symbol is used to depict space launch and reentry areas

on sectional aeronautical charts.

SPEAK SLOWER

-

Used in verbal communications as a request to reduce speech rate.

SPECIAL ACTIVITY AIRSPACE (SAA)

-

 Airspace with defined dimensions within the National Airspace

System wherein limitations may be imposed upon operations
for national defense, homeland security, public

interest, or public safety. Special activity airspace includes but is
not limited to the following; Air Traffic Control

Assigned Airspace (ATCAA), Altitude Reservations (ALTRV), Military
Training Routes (MTR), Air Refueling

Tracks and Anchors, Temporary Flight Restrictions (TFR), Special
Security Instructions (SSI), etc. Special Use

Airspace (SUA) is a subset of Special Activity Airspace.

SPECIAL AIR TRAFFIC RULES (SATR)

-

 Rules that govern procedures for conducting flights in certain areas

listed in 14 CFR Part 93. The term "SATR" is used in the United States
to describe the rules for operations in

specific areas designated in the Code of Federal Regulations.

(Refer to 14 CFR Part 93.)

SPECIAL EMERGENCY

-

 A condition of air piracy or other hostile act by a person(s) aboard
an aircraft which

threatens the safety of the aircraft or its passengers.
SPECIAL FLIGHT RULES AREA (SFRA)

-

 An area in the NAS, described in 14 CFR Part 93, wherein the

flight of aircraft is subject to special traffic rules, unless
otherwise authorized by air traffic control. Not all areas

listed in 14 CFR Part 93 are designated SFRA, but special air traffic
rules apply to all areas described in 14 CFR

Part 93.
SPECIAL GOVERNMENT INTEREST (SGI)

-

 A near real-time airspace authorization for Part 91 or Part 107

UAS, which supports activities that
answer significant and urgent governmental interests. These include:

national defense, homeland security, law enforcement, and
emergency operations objectives.
SPECIAL INSTRUMENT APPROACH PROCEDURE

-

(See INSTRUMENT APPROACH PROCEDURE.)

SPECIAL MILITARY ACTIVITY ROUTE (SMAR)- A route, which may also be
charted on the VFR Sectional

Chart, that shows the extent of the airspace allocated to an associated
IFR Military Training Route within which

the Department of Defense conducts periodic operations involving
Unmanned Aircraft Systems (UAS).
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 are:

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 Arere conducted in accordance with

Federal Aviation Regulations, and pilots of participating aircraft as
well as pilots transiting the arere 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)

-

Permanent and temporary MOAs are airspace established outside of

Class A airspace area to separate or segregate certain nonhazardous
military activities from IFR traffic and to
