2. No Tower, FSS, or UNICOM Self-announce on MULTICOM frequency 122.9. Before taxiing and before taxiing on the runway for departure. 10 miles out. Entering downwind, base, and final. Leaving the runway. Departing final approach fix (name) or on final approach segment inbound. 3. No Tower in operation, FSS open Communicate with FSS on CTAF frequency. Before taxiing and before taxiing on the runway for departure. 10 miles out. Entering downwind, base, and final. Leaving the runway. Approach com-pleted/terminated. 4. FSS Closed (No Tower) Self-announce on CTAF. Before taxiing and before taxiing on the runway for departure. 10 miles out. Entering downwind, base, and final. Leaving the runway. 5. Tower or FSS not in operation Self-announce on CTAF. Before taxiing and before taxiing on the runway for departure. 10 miles out. Entering downwind, base, and final. Leaving the runway. 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. REFERENCE. AIM, Parachute Jump Aircraft Operations, Paragraph 3.5.4. 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. Services Available to Pilots 4.1.3 (b)Remote Airport Advisory (RAA) is provided at selected very busy GA airports, which do not have an operating control tower. The CTAF for RAA airports is disseminated in the appropriate aeronautical publications. (c)Remote Airport Information Ser-vice (RAIS) is provided in support of special events at nontowered airports by request from the airport authority. 2. In communicating with a CTAF FSS, check the airport’s automated weather and establish two.way communications before transmitting out-bound/inbound intentions or information. An inbound aircraft should initiate contact approximate-ly 10 miles from the airport, reporting aircraft identification and type, altitude, location relative to the airport, intentions (landing or over flight), possession of the automated weather, and request airport advisory or airport information service. A departing aircraft should initiate contact before taxiing, reporting aircraft identification and type, VFR or IFR, location on the airport, intentions, direction of take.off, possession of the automated weather, and request airport advisory or information service. Also, report intentions before taxiing onto the active runway for departure. If you must change frequencies for other service after initial report to FSS, return to FSS frequency for traffic update. (a) Inbound EXAMPLE. Vero Beach radio, Centurion Six Niner Delta Delta is ten miles south, two thousand, landing Vero Beach. I have the automated weather, request airport advisory. (b) Outbound EXAMPLE. Vero Beach radio, Centurion Six Niner Delta Delta, ready to taxi to runway 22, VFR, departing to the southwest. I have the automated weather, request airport advisory. 3. Airport advisory service includes wind direction and velocity, favored or designated runway, altimeter setting, known airborne and ground traffic, NOTAMs, airport taxi routes, airport traffic pattern information, and instrument approach procedures. These elements are varied so as to best serve the current traffic situation. Some airport managers have specified that under certain wind or other conditions designated runways be used. Pilots should advise the FSS of the runway they intend to use. CAUTION. All aircraft in the vicinity of an airport may not be in communication with the FSS. e. Information Provided by Aeronautical Advisory Stations (UNICOM)1. UNICOM is a nongovernment air/ground radio communication station which may provide airport information at public use airports where there is no tower or FSS. 2.On pilot request, UNICOM stations may provide pilots with weather information, wind direction, the recommended runway, or other necessary information. If the UNICOM frequency is designated as the CTAF, it will be identified in appropriate aeronautical publications. f. Unavailability of Information from FSS or UNICOM Should LAA by an FSS or Aeronautical Advisory Station UNICOM be unavailable, wind and weather information may be obtainable from nearby controlled airports via Automatic Terminal Informa-tion Service (ATIS) or Automated Weather Observing System (AWOS) frequency. g.
