facilities which provide pilot briefings, en route
communications and VFR search and rescue
services, assist lost aircraft and aircraft in emergency
situations, relay ATC clearances, originate Notices to
Airmen, broadcast aviation weather and National
Airspace System (NAS) information, receive and
process IFR flight plans, and monitor NAVAIDs. In
addition, at selected locations FSSs provide En Route
Flight Advisory Service (Flight Watch), take weather
observations, issue airport advisories, and advise the
U.S. Citizenship and Immigration Services of
transborder flights.
6.3Supplemental Weather Service Locations
(SWSLs) are 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.
6.4FSS locations, services and telephone information
are available in the U.S. Airport/Facility
Directory, Supplement Alaska, and Pacific Chart
Supplement.
6.5Flight Service Station, Pre−Flight information
service coverage is designed primarily to provide
service within a 500−mile area of the Flight Service
Station. All Flight Service Stations, nevertheless, do
have telecommunications access to all of the weather
and NOTAM information available, on an as needed
basis, for preflight briefing to international locations
with which the U.S. International NOTAM office
exchanges information.

4. General Description of Each Chart Series
4.1VFR Navigation Charts
4.1.1Sectional Aeronautical Charts. Sectional
Charts are designed for visual navigation of slow to
medium speed aircraft. The topographic information
consists of contour lines, shaded relief, drainage
patterns, and an extensive selection of visual
checkpoints and landmarks used for flight under
VFR. Cultural features include cities and towns,
roads, railroads, and other distinct landmarks. The
aeronautical information includes visual and radio
aids to navigation, airports, controlled airspace,
special−use airspace, obstructions, and related data.
Scale 1 inch = 6.86nm/1:500,000. 60 x 20 inches
folded to 5 x 10 inches. Revised semiannually, except
most Alaskan charts are revised annually.
(See FIG GEN 3.2−1 and FIG GEN 3.2−11.)
4.1.2VFR Terminal Area Charts (TAC). TACs
depict the airspace designated as Class B airspace.
While similar to sectional charts, TACs have more
detail because the scale is larger. The TAC should be
used by pilots intending to operate to or from airfields
within or near Class B or Class C airspace. Areas with
TAC coverage are indicated by a • on the Sectional
Chart indexes. Scale 1 inch = 3.43nm/1:250,000.
Charts are revised semiannually, except Puerto
Rico−Virgin Islands which is revised annually.
(See FIG GEN 3.2−1 and FIG GEN 3.2−11.)
