PCG S−8

STOP SQUAWK (Mode or Code)− Used by ATC to

tell the pilot to turn specified functions of the aircraft

transponder off.

(See STOP ALTITUDE SQUAWK.)
(See TRANSPONDER.)

STOP STREAM− Used by ATC to request a pilot to

suspend electronic attack activity.

(See JAMMING.)

STOPOVER FLIGHT PLAN− A flight plan format

which permits in a single submission the filing of a

sequence of flight plans through interim full-stop

destinations to a final destination.

STOPWAY− An area beyond the takeoff runway no

less wide than the runway and centered upon the

extended centerline of the runway, able to support the

airplane during an aborted takeoff, without causing

structural damage to the airplane, and designated by

the airport authorities for use in decelerating the

airplane during an aborted takeoff.

STRAIGHT-IN APPROACH IFR− An instrument

approach wherein final approach is begun without

first having executed a procedure turn, not

necessarily completed with a straight-in landing or

made to straight-in landing minimums.

(See LANDING MINIMUMS.)
(See STRAIGHT-IN APPROACH VFR.)
(See STRAIGHT-IN LANDING.)

STRAIGHT-IN APPROACH VFR− Entry into the

traffic pattern by interception of the extended runway

centerline (final approach course) without executing

any other portion of the traffic pattern.

(See TRAFFIC PATTERN.)

STRAIGHT-IN LANDING− A landing made on a

runway aligned within 30

_ of the final approach

course following completion of an instrument

approach.

(See STRAIGHT-IN APPROACH IFR.)

STRAIGHT-IN LANDING MINIMUMS−

(See LANDING MINIMUMS.)

STRAIGHT-IN MINIMUMS−

(See STRAIGHT-IN LANDING MINIMUMS.)

STRATEGIC PLANNING− Planning whereby

solutions are sought to resolve potential conflicts.

SUBSTITUTE ROUTE− A route assigned to pilots

when any part of an airway or route is unusable

because of NAVAID status. These routes consist of:

a. Substitute routes which are shown on U.S.

Government charts.

b. Routes defined by ATC as specific NAVAID

radials or courses.

c. Routes defined by ATC as direct to or between

NAVAIDs.
SUNSET AND SUNRISE− The mean solar times of

sunset and sunrise as published in the Nautical

Almanac, converted to local standard time for the

locality concerned. Within Alaska, the end of evening

civil twilight and the beginning of morning civil

twilight, as defined for each locality.
SUPPLEMENTAL WEATHER SERVICE LOCA-

TION− Airport facilities staffed with contract

personnel who take weather observations and

provide current local weather to pilots via telephone

or radio. (All other services are provided by the parent

FSS.)
SUPPS− Refers to ICAO Document 7030 Regional

Supplementary Procedures. SUPPS contain

procedures for each ICAO Region which are unique

to that Region and are not covered in the worldwide

provisions identified in the ICAO Air Navigation

Plan. Procedures contained in Chapter 8 are based in

part on those published in SUPPS.
SURFACE AREA− The airspace contained by the

lateral boundary of the Class B, C, D, or E airspace

designated for an airport that begins at the surface and

extends upward.
SURPIC− A description of surface vessels in the area

of a Search and Rescue incident including their

predicted positions and their characteristics.

(Refer to FAA Order JO 7110.65, Para 10−6−4,

INFLIGHT CONTINGENCIES.)

SURVEILLANCE APPROACH− An instrument

approach wherein the air traffic controller issues

instructions, for pilot compliance, based on aircraft

position in relation to the final approach course

(azimuth), and the distance (range) from the end of

the runway as displayed on the controller’s radar

scope. The controller will provide recommended

altitudes on final approach if requested by the pilot.

(Refer to AIM.)

SWAP−

(See SEVERE WEATHER AVOIDANCE PLAN.)
