n) information on the location of an accidental release of radioactive materials into the atmosphere of significance to aircraft operations, comprising: the radioactivity symbol at the site of the accident and, at the side of the chart, the radioactivity symbol, latitude/longitude of the site of the accident, date and time of the accident and a reminder to users to check NOTAM for the area concerned. Note 1.— For aircraft operating above flight level 250, items a) to f) are only required if expected to be above that level, and in the case of item a), only those thunderstorms which warrant the issuance of a SIGMET as given in Appendix 6. Guidance on the use of term “FRQ TS” is given in Appendix 6. Note 2.— The abbreviation “CB” should only be included where it refers to the occurrence or expected occurrence of an area of widespread cumulonimbus clouds or cumulonimbus along a line with little or no space between individual clouds, or to cumulonimbus embedded in cloud layers or concealed by haze. It does not refer to isolated or scattered cumulonimbus not embedded in cloud layers or concealed by haze. Note 3.— Where a volcanic eruption or the accidental release of radioactive materials into the atmosphere warrants the inclusion of the volcanic activity symbol or the radioactivity symbol on significant weather charts, the symbols are to be included on all such charts (low, medium and high) irrespective of the height to which the ash column or radioactive material is reported or expected to reach. Note 4.— The international volcano number is allocated by the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI) and is listed in the Manual on Volcanic Ash, Radioactive Material and Toxic Chemical Clouds (Doc 9691). 4.3.1.2 Recommendation.— On significant weather charts, the inclusion of “CB” or the thunderstorm symbol should be understood to include all weather phenomena normally associated with cumulonimbus or thunderstorm, namely, moderate or severe icing, moderate or severe turbulence and hail. 4.3.1.3 Recommendation.— Significant weather charts for low-level flights, including those in accordance with the visual flight rules, operating up to flight level 100 (up to flight level 150 in mountainous areas or higher, where necessary) should show, as appropriate to the flight:
