14. Communications for VFR Flights

a.

FSSs and Supplemental Weather Service

Locations (SWSLs) are allocated frequencies for

different functions; for example, 122.0 MHz is

assigned as the En Route Flight Advisory Service

frequency at selected FSSs. In addition, certain FSSs

provide Local Airport Advisory on 123.6 MHz or

other frequencies which can be found in the A/FD. 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 A/FD. 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.
