volcanic ash from the volcano has entered the FIR, or is expected to do so, this will be indicated in a separate box displayed on the GSM (refer to the examples in Appendix 1).
2.9. SIGMETs are not displayed in the NZZO GSM south of 60S, the southern limit of the NZZO GSM
product. However, textual SIGMETs will be provided for NZZO south of 60S (to South Pole).
2.10. The boundary of NZZC is shown on the NZZO GSM, but SIGMETs for NZZC are not displayed within
this area of the NZZO GSM. The graphical display of SIGMETs in NZZC is restricted to the NZZC GSM product.
3. Accessing the GSM 3.1. The GSM will be available via all aviation delivery systems ‐ MetFlight GA, MetFlight Commercial,
MetJet, WeatherTrakII and aviation web pages.
3.2. For MetJet and WeatherTrakII uses the GSM will be included in any existing packages you have by default there is nothing you need to do to include these.
3.3. For all other users, when generating a weather briefing the GSM will automatically be included if SIGMETs have been selected as part of the briefing.
4. Release Date 4.1. The GSM is planned for release on 29 July 2015.
5. Examples 5.1. Examples of the GSM for each FIR and guidance notes for interpretation of the GSM are provided
in Appendix 1.

Explanation and Decode
NZZC An explanation and decode of the information displayed is given for the following example. The
numbering in the explanation and decode is the same as the numbering of each SIGMET displayed in
the GSM.
This example shows that SIGMETs numbered 1, 6 and 8 are the current valid SIGMETs in the NZZC FIR.
SIGMETs numbered 2 – 5 and 7 have expired or were cancellation messages.
