Appendix 7
Template for advisory message for tropical cyclones Key:
Note 1: The ranges and resolutions for the numerical elements included in advisory messages for tropical cyclones are shown in Appendix 8. Note 2: The explanations for the abbreviations can be found in Procedures for Air Navigation Services — ICAO Abbreviations and Codes (PANS-ABC, Doc 8400). Note 3: All the elements are mandatory. Note 4: Inclusion of a ‘colon’ after each element heading is mandatory. Note 5: The numbers 1 to 19 are included only for clarity and they are not part of the advisory message, as shown in the example. |
