Pilot/Controller Glossary

3/29/18

PCG S−7

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.)

STANDARD TERMINAL AUTOMATION RE-

PLACEMENT SYSTEM (STARS)−

(See DTAS.)

STAR−

(See STANDARD TERMINAL ARRIVAL.)

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

the verbally reported altitude varies 300 feet or more

from the automatic altitude report.

(See ALTITUDE READOUT.)
(See TRANSPONDER.)

STOP AND GO− A procedure wherein an aircraft

will land, make a complete stop on the runway, and

then commence a takeoff from that point.

(See LOW APPROACH.)
(See OPTION APPROACH.)

STOP BURST−

(See STOP STREAM.)

STOP BUZZER−

(See STOP STREAM.)
