2. SPECIFICATIONS RELATED TO AIRMET INFORMATION 2.1 Format of AIRMET messages 2.1.1 The content and order of elements in an AIRMET message shall be in accordance with the template shown in Table A6-1. Appendix 6 Annex 3 — Meteorological Service for International Air Navigation APP 6-3 7/11/07 2.1.2 The sequence number referred to in the template in Table A6-1 shall correspond with the number of AIRMET messages issued for the flight information region since 0001 UTC on the day concerned. The meteorological watch offices whose area of responsibility encompasses more than one FIR and/or CTA shall issue separate AIRMET messages for each FIR and/or CTA within its area of responsibility. 2.1.3 The flight information region shall be divided in sub-areas, as necessary. 2.1.4 In accordance with the template in Table A6-1, only one of the following phenomena shall be included in an AIRMET message, using the abbreviations as indicated below: At cruising levels below flight level 100 (or below flight level 150 in mountainous areas, or higher, where necessary): — surface wind speed – widespread mean surface SFC WSPD wind speed above 60 km/h (30 kt) (+ wind speed and units) — surface visibility – widespread areas affected SFC VIS by reduction of visibility to less than (+ visibility) 5 000 m, including the weather (+ one of the following weather phenomena or combinations phenomenon causing the reduction thereof: BR, DS, DU, DZ, FC, FG, FU, GR, GS, HZ, IC, PL, of visibility PO, RA, SA, SG, SN, SQ, SS or VA) — thunderstorms – isolated thunderstorms ISOL TS without hail – occasional thunderstorms OCNL TS without hail – isolated thunderstorms ISOL TSGR with hail – occasional thunderstorms OCNL TSGR with hail — mountain obscuration – mountains obscured MT OBSC — cloud – widespread areas of broken or overcast cloud with height of base less than 300 m (1 000 ft) above ground level: – broken BKN CLD (+ height of the base and top and units) – overcast OVC CLD (+ height of the base and top and units) – cumulonimbus clouds which are: – isolated ISOL CB – occasional OCNL CB – frequent FRQ CB – towering cumulus clouds which are: – isolated ISOL TCU – occasional OCNL TCU – frequent FRQ TCU Annex 3 — Meteorological Service for International Air Navigation Appendix 6 7/11/07 APP 6-4 — icing – moderate icing (except for icing MOD ICE in convective clouds) — turbulence – moderate turbulence (except for MOD TURB turbulence in convective clouds) — mountain wave – moderate mountain wave MOD MTW 2.1.5 AIRMET information shall not contain unnecessary descriptive material. In describing the weather phenomena for which the AIRMET is issued, no descriptive material additional to that given in 2.1.4 shall be included. AIRMET information concerning thunderstorms or cumulonimbus clouds shall not include references to associated turbulence and icing. Note.— The specifications for SIGMET information which is also applicable to low-level flights are given in 1.1.4. 2.2 Dissemination of AIRMET messages 2.2.1 Recommendation.— AIRMET messages should be disseminated to meteorological watch offices in adjacent flight information regions and to other meteorological offices, as agreed by the meteorological authorities concerned. 2.2.2 Recommendation.— AIRMET messages should be transmitted to international operational meteorological databanks and the centres designated by regional air navigation agreement for the operation of aeronautical fixed service satellite distribution systems, in accordance with regional air navigation agreement.
