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

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.)

STRATEGIC PLANNING- Planning whereby

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

SUPPLEMENTAL WEATHER SERVICE LOCATION- Airport facilities staffed with contract
personnel who take weather observations and
provide current local weather to pilots via telephone

FSS.)
SUPPS- Refers to ICAO Document 7030 Regional
Supplementary Procedures. SUPPS contain
procedures for each ICAO Region which are unique

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
