2.
The CTAF frequency for a particular airport
is contained in the A/FD, Alaska Supplement, Alaska
Terminal Publication, Instrument Approach Proce-
dure Charts, and Instrument Departure
Procedure (DP) Charts. Also, the CTAF frequency
can be obtained by contacting any FSS. Use of the
appropriate CTAF, combined with a visual alertness
and application of the following recommended good
operating practices, will enhance safety of flight into
and out of all uncontrolled airports.
c. Recommended Traffic Advisory Practices
1.
Pilots of inbound traffic should monitor and
communicate as appropriate on the designated CTAF
from 10 miles to landing. Pilots of departing aircraft
should monitor/communicate on the appropriate
frequency from start-up, during taxi, and until
10 miles from the airport unless the CFRs or local
procedures require otherwise.
2.
Pilots of aircraft conducting other than
arriving or departing operations at altitudes normally
used by arriving and departing aircraft should
monitor/communicate on the appropriate frequency
while within 10 miles of the airport unless required to
do otherwise by the CFRs or local procedures. Such
operations include parachute jumping/dropping, en
route, practicing maneuvers, etc.

d. Airport Advisory/Information Services
Provided by a FSS
1.
There are three advisory type services
provided at selected airports.
(a)
Local Airport Advisory (LAA) is pro-
vided at airports that have a FSS physically located on
the airport, which does not have a control tower or
where the tower is operated on a part−time basis. The
CTAF for LAA airports is disseminated in the
appropriate aeronautical publications.
