14. Communications for VFR Flights

a.

FSSs and Supplemental Weather Service

Locations (SWSL) are allocated frequencies for
different functions; for example, in Alaska, certain
FSSs provide Local Airport Advisory on 123.6 MHz
or other frequencies which can be found in the Chart
Supplement U.S. If you are in doubt as to what
frequency to use, 122.2 MHz is assigned to the
majority of FSSs as a common en route simplex
frequency.

NOTE

−

In order to expedite communications, state the frequency
being used and the aircraft location during initial callup.

b.

Certain VOR voice channels are being utilized

for recorded broadcasts; i.e., ATIS, HIWAS, etc.
These services and appropriate frequencies are listed
in the Chart Supplement U.S. On VFR flights, pilots
are urged to monitor these frequencies. When in
contact with a control facility, notify the controller if
you plan to leave the frequency to monitor these
broadcasts.
