Latest update of full suite SIG-Coord platform with IWXXM feature enabled
HKO News Bulletin for the Aviation Community (40th Issue)
To support and promote SIGMET coordination among neighbouring FIRs, the Hong Kong Observatory has developed a web platform, named the Regional SIGMET Coordination (SIG-Coord) Platform since 2016. Full suite SIG-Coord platform with four tabs for five subclasses of SIGMET has been launched in late 2020 to meet the new requirements in Amendments 79 of International Civil Aviation Organization (ICAO) Annex III. The platform helps facilitate common situation awareness and Meteorological Watch Offices (MWOs) to perform SIGMET coordination with neighbouring MWOs.
