曝光台 注意防骗 网曝天猫店富美金盛家居专营店坑蒙拐骗欺诈消费者

EXAMPLE.
“Kotzebue information ALPHA. One six five five zulu. Wind, two one zero at five; visibility two, fog; ceiling one hundred overcast; temperature minus one two, dew point minus one four; altimeter three one zero five. Altimeter in excess of three one zero zero, high pressure altimeter setting procedures are in effect. Favored runway two six. Weather in Kotzebue surface area is below V.F.R minima . an ATC clearance is required. Contact Kotzebue Radio on 123.6 for traffic advisories and advise intentions. Notice to Airmen, Hotham NDB out of service. Transcribed Weather Broadcast out of service. Advise on initial contact you have ALPHA.”
NOTE.
The absence of a sky condition or ceiling and/or visibility on Alaska FSS AFIS indicates a sky condition or ceiling of 5,000 feet or above and visibility of 5 miles or more. A remark may be made on the broadcast, “the weather is better than 5000 and 5.”
 b) Pilots should listen to Alaska FSSs AFIS broadcasts whenever Alaska FSSs AFIS is in operation.
NOTE.
Some Alaska FSSs are open part time and/or seasonally.
 c) Pilots should notify controllers on initial contact that they have received the Alaska FSSs AFIS broadcast by repeating the phonetic alphabetic letter appended to the broadcast.
EXAMPLE.
“Information Alpha received.”
 d) While it is a good operating practice for pilots to make use of the Alaska FSS AFIS broadcast where it is available, some pilots use the phrase “have numbers” in communications with the FSS. Use of this phrase means that the pilot has received wind, runway, and altimeter information ONLY and the Alaska FSS does not have to repeat this information. It does not indicate receipt of the AFIS broadcast and should never be used for this purpose.
CAUTION. All aircraft in the vicinity of an airport may not be in communication with the FSS.
9.2.5 Information Provided by Aeronautical Advisory Stations (UNICOM)
9.2.5.1 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.
9.2.5.2 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.
9.2.5.3 Unavailability of Information from FSS or UNICOM. Should LAA by an FSS or Aeronautical Advisory Station UNICOM be unavail-able, wind and weather information may be obtainable from nearby controlled airports via Automatic Terminal Information Service (ATIS) or Automated Weather Observing System (AWOS) frequency.
9.2.6 Self.Announce Position and/or Intentions
9.2.6.1 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.
9.2.6.2 If an airport has a tower which 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.
9.2.6.3 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.

9.2.6.4 Practice Approaches.  Pilots conducting practice instrument approaches should be particular-ly alert for other aircraft that may be departing in the 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 proce-dure.
9.2.6.5 Departing aircraft should always be alert for arrival aircraft coming from the opposite direction.
9.2.6.6 Recommended Self.Announce Phraseol-ogies. 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.
