ability to detect targets.
j. Visual Obstructions in the Cockpit.
1. Pilots need to move their heads to see around
blind spots caused by fixed aircraft structures, such as
door posts, wings, etc. It will be necessary at times to
maneuver the aircraft; e.g., lift a wing, to facilitate
seeing.
2. Pilots must insure curtains and other cockpit
objects; e.g., maps on glare shield, are removed and
stowed during flight.
k. Lights On.
1. Day or night, use of exterior lights can greatly
increase the conspicuity of any aircraft.
2. Keep interior lights low at night.
l. ATC Support. ATC facilities often provide
radar traffic advisories on a workload‐permitting
basis. Flight through Class C and Class D airspace
requires communication with ATC. Use this support
whenever possible or when required.

9-1-4. General Description of each Chart
Series
a. VFR Navigation Charts.
1. Sectional 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 9-1-1 and FIG 9-1-11.)
2. VFR 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 revised annually.
(See FIG 9-1-1 and FIG 9-1-11.)
3. World Aeronautical Chart (WAC). WACs
cover land areas for navigation by moderate speed
aircraft operating at high altitudes. Included are city
tints, principal roads, railroads, distinctive landmarks,
drainage patterns, and relief. Aeronautical
information includes visual and radio aids to
navigation, airports, airways, special-use airspace,
and obstructions. Because of a smaller scale, WACs
do not show as much detail as sectional or TACs, and;
therefore, are not recommended for exclusive use by
pilots of low speed, low altitude aircraft. Scale
1inch= 13.7nm/1:1,000,000. 60 x 20 inches folded
to 5 x 10 inches. WACs are revised annually, except
for a few in Alaska and the Caribbean, which are
revised biennially.
(See FIG 9-1-12 and FIG 9-1-13.)
