3.12 FREQUENCIES FOR NEAREST FLIGHT
SERVICE STATIONS
The KLN 900 stores in its database the locations of Flight
Service Stations (FSS) and their remote communications
sites. In addition, the KLN 900 determines which two of
these FSS points of communication are closest to your
present location. What a convenience for you! Next time
you want to file a flight plan from the air or contact a FSS
for some other reason, you can easily use the KLN 900 to
determine a suitable FSS and the appropriate frequency.
NOTE: In some areas of the world the KLN 900 provides
the location of the nearest point of communication with a
facility providing information (INF) or radio (RDO) ser-
vices.
Select the Other 1 page (OTH 1) on the left side to view
two of the nearest points of communication with Flight
Service Stations. There will normally be two OTH 1
pages, one for each of the two points of contact. The
name of the FSS is at the top of the page. There can be
from one to four frequencies included for a point of con-
tact (figure 3-160). Remember that in the U.S. the fre-
quency 122.00 MHz is used for "Flight Watch" and the
frequency 123.60 MHz is used for Aeronautical Advisory
Service. As you know, it is often possible to communi-
cate with a FSS by transmitting on 122.10 MHz and lis-
tening on the VOR frequency. In cases like this, the OTH
1 page displays the frequencies to use for transmit and
receive and also the VOR name through which you are
communicating (figure 3-161).
In some parts of the world, high frequency (HF) communi-
cations are used for these services. HF frequencies are
displayed on the OTH 1 page where appropriate.
Remember, you can easily recognize HF frequencies
because they do not have a decimal point.
3.13 FREQUENCIES FOR AIR ROUTE
TRAFFIC CONTROL CENTERS
(ARTCC)
The KLN 900 also stores in its database the low altitude
boundaries of each of the ARTCC "Centers". The KLN
900 determines the proper Center to contact and the
appropriate frequencies to use for the aircraft's present
position. The Other 2 page (OTH 2) is used to display
this information to you (figure 3-162). Next time you wish
to obtain VFR flight following or communicate with Center
for any reason, you have a quick way to get a frequency
for establishing contact! Appendix D contains a listing of
Center abbreviations used on the OTH 2 page.
NOTE: Frequencies for Area Control Centers are dis-
played on the OTH 2 page for some areas of the world.
