b) printed communications, when a record is required by the recipients; the message transit time should not exceed 5 minutes. Note.— In 11.1.4 and 11.1.5, “approximately 15 seconds” refers to telephony communications involving switchboard operation and “5 minutes” refers to printed communications involving retransmission. Annex 3 — Meteorological Service for International Air Navigation Chapter 11 7/11/07 11-2 11.1.6 Recommendation.— The telecommunications facilities required in accordance with 11.1.4 and 11.1.5 should be supplemented, as and where necessary, by other forms of visual or audio communications, for example, closed-circuit television or separate information processing systems. 11.1.7 Recommendation.— As agreed between the meteorological authority and operators, provision should be made to enable operators to establish suitable telecommunications facilities for obtaining meteorological information from aerodrome meteorological offices or other appropriate sources. 11.1.8 Suitable telecommunications facilities shall be made available to permit meteorological offices to exchange operational meteorological information with other meteorological offices. 11.1.9 Recommendation.— The telecommunications facilities used for the exchange of operational meteorological information should be the aeronautical fixed service. 11.2 Use of aeronautical fixed service communications — meteorological bulletins in alphanumeric format Meteorological bulletins containing operational meteorological information to be transmitted via the aeronautical fixed service shall be originated by the appropriate meteorological office or aeronautical meteorological station. Note.— Meteorological bulletins containing operational meteorological information authorized for transmission via the aeronautical fixed service are listed in Annex 10, Volume II, Chapter 4, together with the relevant priorities and priority indicators. 11.3 Use of aeronautical fixed service communications — world area forecast system products Recommendation.— World area forecast system products in digital form should be transmitted using binary data communications techniques. The method and channels used for the dissemination of the products should be as determined by regional air navigation agreement. 11.4 Use of aeronautical mobile service communications The content and format of meteorological information transmitted to aircraft and by aircraft shall be consistent with the provisions of this Annex. 11.5 Use of aeronautical data link service — contents of D-VOLMET D-VOLMET shall contain current METAR and SPECI, together with trend forecasts where available, TAF and SIGMET, special air-reports not covered by a SIGMET and, where available, AIRMET. Note.— The requirement to provide METAR and SPECI may be met by the data link-flight information service (D-FIS) application entitled “Data link-aerodrome routine meteorological report (D-METAR) service”; the requirement to provide TAF may be met by the D-FIS application entitled “Data link-aerodrome forecast (D-TAF) service”; and the requirement to provide SIGMET and AIRMET messages may be met by the D-FIS application entitled “Data link-SIGMET (D-SIGMET) service”. The details of these data link services are specified in the Manual of Air Traffic Services Data Link Applications (Doc 9694). Chapter 11 Annex 3 — Meteorological Service for International Air Navigation 11-3 7/11/07 11.6 Use of aeronautical broadcasting service — contents of VOLMET broadcasts 11.6.1 Continuous VOLMET broadcasts, normally on very high frequencies (VHF), shall contain current METAR and SPECI, together with trend forecasts where available. 11.6.2 Scheduled VOLMET broadcasts, normally on high frequencies (HF), shall contain current METAR and SPECI, together with trend forecasts where available and, where so determined by regional air navigation agreement, TAF and SIGMET. ___________________ INTERNATIONAL STANDARDS AND RECOMMENDED PRACTICES PART II APPENDICES AND ATTACHMENTS ANNEX 3 APP 1-1 7/11/07 APPENDIX 1 FLIGHT DOCUMENTATION ʊ MODEL CHARTS AND FORMS (See Chapter 9 of this Annex.)
