ICAO compliant Canadian SIGMET/AIRMET

In November 2013, Canada converted to an ICAO-compliant significant meteorological information (SIGMET) and aviation weather advisory (AIRMET) bulletin format. As this new format contains differences from the one in use prior to the change, a presentation detailing all the changes is available below.

This presentation allows stakeholders to review the new format and its subtleties as well as answer any questions regarding this change.

Do not hesitate to contact customer service at service@navcanada.ca should you have additional questions or comments.
