4−2−14. 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.

EXAMPLE−

Dayton radio, November One Two Three Four Five on one

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.
