3.2 Information recorded on the volcanic activity reporting form (Model VAR) is not for transmission by RTF but, on arrival at an aerodrome, is to be delivered without delay by the operator or a flight crew member to the aerodrome meteorological office. If such an office is not easily accessible, the completed form shall be delivered in accordance with local arrangements made between the Meteorological and ATS Authorities and the operator.
4. Forwarding of meteorological information received by voice communications
4.1 When receiving routine or special air-reports, air traffic services units shall forward these air-reports without delay to the associated meteorological watch office (MWO). In order to ensure assimilation of air-reports in ground-based automated systems, the elements of such reports shall be transmitted using the data conventions specified below and in the order prescribed.
—
ADDRESSEE. Record station called and, when necessary, relay required.
—
MESSAGE TYPE DESIGNATOR. Record “ARS” for a special air-report.
Note.— Where air-reports are handled by automatic data processing equipment which cannot accept this message-type designator, in accordance with Part IX, 4.2.5.5.2, the use of a different message-type designator is permitted by regional air navigation agreement.
— AIRCRAFT IDENTIFICATION. Record the aircraft identification using the data convention specified for Item 7 of the flight plan, without a space between the operator’s designator and the aircraft registration or flight identification, if used (e.g. New Zealand 103 as ANZ103).
Rules of the Air and Air Traffic Services (PANS-RAC)
Section 1
Item 0 — POSITION. Record position in latitude (degrees as 2 numerics or degrees and minutes as 4 numerics, followed without a space by N or S) and longitude (degrees as 3 numerics or degrees and minutes as 5 numerics, followed without a space by E or W), or as a significant point identified by a coded designator (2 to 5 characters), or as a significant point followed by magnetic bearing (3 numerics) and distance in nautical miles (3 numerics) from the point (e.g. 4620N07805W, 4620N078W, 46N078W, LN, MAY, HADDY or DUB180040). Precede significant point by “ABM” (abeam), if applicable.
Item 1 — TIME. Record time in hours and minutes UTC (4 numerics).
Item 2 — FLIGHT LEVEL OR ALTITUDE. Record F followed by 3 numerics
(e.g. F310), when a flight level is reported. Record altitude in metres followed by M or in feet followed by FT, when an altitude is reported. Record “ASC” (level) when climbing, or “DES” (level) when descending.
Section 3
Item 8 — AIR TEMPERATURE. Record “PS” (plus) or “MS” (minus) followed, without a space, by the temperature in degrees Celsius (2 numerics)
(e.g. MS05).
Item 9 — WIND DIRECTION.
Item 10 — WIND SPEED. Record wind direction in degrees true (3 numerics) and wind speed in kilometres per hour or knots (2 or 3 numerics), separated by an oblique stroke, indicating the unit used (e.g. 345/55KMH, 170/65KT). Record calm as “00000”.
Item 11 — TURBULENCE. Record severe turbulence as TURB SEV and moderate turbulence as TURB MOD and light turbulence as TURB FBL.
Item 12 — AIRCRAFT ICING. Record severe icing as ICE SEV, moderate icing as ICE MOD and light icing as ICE FBL.
Item 13 — HUMIDITY. If reported, record “RH” followed, without a space, by the humidity in per cent (3 numerics, e.g. RH085).
Note.— Item 13 is optional and shall be included only when available.
Item 14 — PHENOMENON PROMPTING A SPECIAL AIR-REPORT. Record the phenomenon reported as follows: 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：Rules of the Air and Air Traffic Services(128)
