AERIAL REFUELING− A procedure used by the
military to transfer fuel from one aircraft to another
during flight.
(Refer to VFR/IFR Wall Planning Charts.)
AERODROME− A defined area on land or water
(including any buildings, installations and equipment)
intended to be used either wholly or in part for
the arrival, departure, and movement of aircraft.
AERODROME BEACON [ICAO]− Aeronautical
beacon used to indicate the location of an aerodrome
from the air.
AERODROME CONTROL SERVICE [ICAO]− Air
traffic control service for aerodrome traffic.
AERODROME CONTROL TOWER [ICAO]− A
unit established to provide air traffic control service
to aerodrome traffic.
AERODROME ELEVATION [ICAO]− The elevation
of the highest point of the landing area.
AERODROME TRAFFIC CIRCUIT [ICAO]− The
specified path to be flown by aircraft operating in the
vicinity of an aerodrome.
AERONAUTICAL BEACON− A visual NAVAID
displaying flashes of white and/or colored light to
indicate the location of an airport, a heliport, a

landmark, a certain point of a Federal airway in
mountainous terrain, or an obstruction.
(See AIRPORT ROTATING BEACON.)
(Refer to AIM.)
AERONAUTICAL CHART− A map used in air
navigation containing all or part of the following:
topographic features, hazards and obstructions, navigation
aids, navigation routes, designated airspace,
and airports. Commonly used aeronautical charts are:
a. Sectional Aeronautical Charts (1:500,000)−
Designed for visual navigation of slow or medium
speed aircraft. Topographic information on these
charts features the portrayal of relief and a judicious
selection of visual check points for VFR flight.
Aeronautical information includes visual and radio
aids to navigation, airports, controlled airspace,
restricted areas, obstructions, and related data.
b. VFR Terminal Area Charts (1:250,000)− Depict
Class B airspace which provides for the control
or segregation of all the aircraft within Class B
airspace. The chart depicts topographic information
and aeronautical information which includes visual
and radio aids to navigation, airports, controlled
airspace, restricted areas, obstructions, and related
data.
c. World Aeronautical Charts (WAC)
(1:1,000,000)− Provide a standard series of aeronautical
charts covering land areas of the world at a size
and scale convenient for navigation by moderate
speed aircraft. Topographic information includes
cities and towns, principal roads, railroads, distinctive
landmarks, drainage, and relief. Aeronautical
information includes visual and radio aids to navigation,
airports, airways, restricted areas, obstructions,
and other pertinent data.
d. En Route Low Altitude Charts− Provide aeronautical
information for en route instrument navigation
(IFR) in the low altitude stratum. Information
includes the portrayal of airways, limits of controlled
airspace, position identification and frequencies of
radio aids, selected airports, minimum en route and
minimum obstruction clearance altitudes, airway
distances, reporting points, restricted areas, and
related data. Area charts, which are a part of this
series, furnish terminal data at a larger scale in
congested areas.
e. En Route High Altitude Charts− Provide aeronautical
information for en route instrument navigation
(IFR) in the high altitude stratum. Information
includes the portrayal of jet routes, identification and
frequencies of radio aids, selected airports, distances,
time zones, special use airspace, and related information.
f. Instrument Approach Procedures (IAP) Charts−
Portray the aeronautical data which is required to
execute an instrument approach to an airport. These
charts depict the procedures, including all related
data, and the airport diagram. Each procedure is
designated for use with a specific type of electronic
navigation system including NDB, TACAN, VOR,
ILS/MLS, and RNAV. These charts are identified by
the type of navigational aid(s) which provide final
approach guidance.
g. Instrument Departure Procedure (DP) Charts−
Designed to expedite clearance delivery and to
facilitate transition between takeoff and en route
