Airport Tower Communications are provided
in a columnized tabulation for all tower-controlled
airports that appear on the respective chart. Airport
names are listed alphabetically. If the airport is military,
the type of airfield, e.g., AAF, AFB, NAS, is shown
after the airfield name. In addition to the airport name,
tower operating hours, primary VHF/UHF local Control
Tower (CT), Ground Control (GND CON), and Automatic
Terminal Information Service (ATIS) frequencies,
when available, will be given. An asterisk (*)
indicates that the part-time tower frequency is remoted
to a collocated full-time FSS for use as Airport Advisory
Service (AAS) when the tower is closed. Airport
Surveillance Radar (ASR) and/or Precision Approach
Radar (PAR) procedures are listed when available.

Approach Control Communications are
provided in a columnized tabulation listing Class B,
Class C, Terminal Radar Service Areas (TRSA) and
Selected Radar Facilities when available. Primary
VHF/UHF frequencies are provided for each facility.
Sectorization occurs when more than one frequency
exists and/or is approach direction dependent. Availability
of service hours is also provided.

Special Use Airspace (SUA) Prohibited, Restricted
and Warning Areas are presented in blue and
listed numerically for U.S. and other countries. Restricted,
Danger and Advisory Areas outside the U.S.
are tabulated separately in blue. A tabulation of Alert
Areas (listed numerically) and Military Operations Areas
(MOA) (listed alphabetically) appear on the chart
in magenta. All are supplemented with altitude, time of
use and the controlling agency/contact facility, and its
frequency, when available. The controlling agency will
be shown when the contact facility and frequency data
is unavailable.
