1.General. Self-announce is a procedure whereby pilots broadcast their position or intended flight activity or ground operation on the designated CTAF. This procedure is used primarily at airports which do not have an FSS on the airport. The self-announce procedure should also be used if a pilot is unable to communicate with the FSS on the designated CTAF. Pilots stating, “Traffic in the area, please advise” is not a recognized Self.Announce Position and/or Intention phrase and should not be used under any condition. 2.If an airport has a tower and it is temporarily closed, or operated on a part-time basis and there is no FSS on the airport or the FSS is closed, use the CTAF to self-announce your position or intentions. 3.Where there is no tower, FSS, or UNICOM station on the airport, use MULTICOM frequency 122.9 for self-announce procedures. Such airports will be identified in appropriate aeronautical information publications. 4. Practice Approaches. Pilots conducting practice instrument approaches should be particular-ly alert for other aircraft that may be departing in the Services Available to Pilots 4.1.4 opposite direction. When conducting any practice approach, regardless of its direction relative to other airport operations, pilots should make announce-ments on the CTAF as follows: (a)Departing the final approach fix, inbound (nonprecision approach) or departing the outer marker or fix used in lieu of the outer marker, inbound (precision approach); (b)Established on the final approach segment or immediately upon being released by ATC; (c)Upon completion or termination of the approach; and (d)Upon executing the missed approach procedure. 5.Departing aircraft should always be alert for arrival aircraft coming from the opposite direction. 6.Recommended self-announce phraseologies: It should be noted that aircraft operating to or from another nearby airport may be making self-announce broadcasts on the same UNICOM or MULTICOM frequency. To help identify one airport from another, the airport name should be spoken at the beginning and end of each self-announce transmission. (a) Inbound EXAMPLE. Strawn traffic, Apache Two Two Five Zulu, (position), (altitude), (descending) or entering downwind/base/final (as appropriate) runway one seven full stop, touch.and. go, Strawn. Strawn traffic Apache Two Two Five Zulu clear of runway one seven Strawn. (b) Outbound EXAMPLE. Strawn traffic, Queen Air Seven One Five Five Bravo (location on airport) taxiing to runway two six Strawn. Strawn traffic, Queen Air Seven One Five Five Bravo departing runway two six. Departing the pattern to the (direction), climbing to (altitude) Strawn. (c) Practice Instrument Approach EXAMPLE. Strawn traffic, Cessna Two One Four Three Quebec (position from airport) inbound descending through (altitude) practice (name of approach) approach runway three five Strawn. Strawn traffic, Cessna Two One Four Three Quebec AIM practice (type) approach completed or terminated runway three five Strawn. h. UNICOM Communications Procedures 1. In communicating with a UNICOM station, the following practices will help reduce frequency congestion, facilitate a better understanding of pilot intentions, help identify the location of aircraft in the traffic pattern, and enhance safety of flight: (a)Select the correct UNICOM frequency. (b)State the identification of the UNICOM station you are calling in each transmission. (c)Speak slowly and distinctly. (d)Report approximately 10 miles from the airport, reporting altitude, and state your aircraft type, aircraft identification, location relative to the airport, state whether landing or overflight, and request wind information and runway in use. (e)Report on downwind, base, and final approach. (f)Report leaving the runway. 2. Recommended UNICOM phraseologies: (a) Inbound PHRASEOLOGY. FREDERICK UNICOM CESSNA EIGHT ZERO ONE TANGO FOXTROT 10 MILES SOUTHEAST DESCENDING THROUGH (altitude) LANDING FREDERICK, REQUEST WIND AND RUNWAY INFORMATION FREDERICK. FREDERICK TRAFFIC CESSNA EIGHT ZERO ONE TANGO FOXTROT ENTERING DOWNWIND/BASE/ FINAL (as appropriate) FOR RUNWAY ONE NINER (full stop/touch.and.go) FREDERICK. FREDERICK TRAFFIC CESSNA EIGHT ZERO ONE TANGO FOXTROT CLEAR OF RUNWAY ONE NINER FREDERICK. (b) Outbound PHRASEOLOGY. FREDERICK UNICOM CESSNA EIGHT ZERO ONE TANGO FOXTROT (location on airport) TAXIING TO RUNWAY ONE NINER, REQUEST WIND AND TRAFFIC INFORMATION FREDERICK. FREDERICK TRAFFIC CESSNA EIGHT ZERO ONE TANGO FOXTROT DEPARTING RUNWAY ONE NINER. “REMAINING IN THE PATTERN” OR “DEPARTING THE PATTERN TO THE (direction) (as appropriate)” FREDERICK. Services Available to Pilots 4.1.5 4.1.10. IFR Approaches/Ground Vehicle Operations a.IFR Approaches. When operating in accor-dance with an IFR clearance and ATC approves a change to the advisory frequency, make an expeditious change to the CTAF and employ the recommended traffic advisory procedures. b.Ground Vehicle Operation. Airport ground vehicles equipped with radios should monitor the CTAF frequency when operating on the airport movement area and remain clear of runways/taxi-ways being used by aircraft. Radio transmissions from ground vehicles should be confined to safety-related matters. c. Radio Control of Airport Lighting Systems. Whenever possible, the CTAF will be used to control airport lighting systems at airports without operating control towers. This eliminates the need for pilots to change frequencies to turn the lights on and allows a continuous listening watch on a single frequency. The CTAF is published on the instrument approach chart and in other appropriate aeronautical information publications.
