transponder; e.g., “Squawk three/alpha, two one zero
five, low.”

(See TRANSPONDER.)

STA

−

(See SCHEDULED TIME OF ARRIVAL.)

STAGING/QUEUING

−

 The placement, integration,

and segregation of departure aircraft in designated
movement areas of an airport by departure fix, EDCT,
and/or restriction.

STAND BY

−

 

Means the controller or pilot must

pause for a few seconds, usually to attend to other
duties of a higher priority. Also means to wait as in
“stand by for clearance.” The caller should
reestablish contact if a delay is lengthy. “Stand by” is
not an approval or denial.

STANDARD INSTRUMENT APPROACH PRO-
CEDURE (SIAP)

−

(See INSTRUMENT APPROACH PROCEDURE.)

STANDARD INSTRUMENT DEPARTURE (SID)

−

A preplanned instrument flight rule (IFR) air traffic
control (ATC) departure procedure printed for
pilot/controller use in graphic form to provide
obstacle clearance and a transition from the terminal
area to the appropriate en route structure. SIDs are
primarily designed for system enhancement to
expedite traffic flow and to reduce pilot/controller
workload. ATC clearance must always be received
prior to flying a SID.

(See IFR TAKEOFF MINIMUMS AND

DEPARTURE PROCEDURES.)

(See OBSTACLE DEPARTURE PROCEDURE.)

(Refer to AIM.)

STANDARD RATE TURN

−

 A turn of three degrees

per second.

STANDARD TERMINAL ARRIVAL (STAR)

−

 A

preplanned instrument flight rule (IFR) air traffic
control arrival procedure published for pilot use in
graphic and/or textual form. STARs provide
transition from the en route structure to an outer fix
or an instrument approach fix/arrival waypoint in the
terminal area.

STANDARD TERMINAL ARRIVAL CHARTS

(See AERONAUTICAL CHART.)

STATE AIRCRAFT

−

 Aircraft used in military,

customs and police service, in the exclusive service
of any government or of any political subdivision
thereof, including the government of any state,
territory, or possession of the United States or the
District of Columbia, but not including any
government-owned aircraft engaged in carrying
persons or property for commercial purposes.

STATIC RESTRICTIONS

−

 Those restrictions that

are usually not subject to change, fixed, in place,
and/or published.

STATIONARY RESERVATIONS

−

 Altitude

reservations which encompass activities in a fixed
area. Stationary reservations may include activities,
such as special tests of weapons systems or
equipment, certain U.S. Navy carrier, fleet, and
anti-submarine operations, rocket, missile and drone
operations, and certain aerial refueling or similar
operations.

STEP TAXI

−

 To taxi a float plane at full power or

high RPM.

STEP TURN

−

 A maneuver used to put a float plane

in a planing configuration prior to entering an active
sea lane for takeoff. The STEP TURN maneuver
should only be used upon pilot request.

STEPDOWN FIX

−

 A fix permitting additional

descent within a segment of an instrument approach
procedure by identifying a point at which a
controlling obstacle has been safely overflown.

STEREO ROUTE

−

 A routinely used route of flight

established by users and ARTCCs identified by a
coded name; e.g., ALPHA 2. These routes minimize
flight plan handling and communications.

STOL AIRCRAFT

−

(See SHORT TAKEOFF AND LANDING

AIRCRAFT.)

STOP ALTITUDE SQUAWK

−

 

Used by ATC to

inform an aircraft to turn off the automatic altitude
reporting feature of its transponder. It is issued when
