Under the ICAO MET Panel, there are five working groups that are tasked with delivering the MET Panel work programme:

  • Meteorological Requirements and Development (MRAD)
  • Meteorological Information Exchange (MIE)
  • Meteorological Operations Group (MOG)
  • Meteorological Cost Recovery Guidance and Governance (MCRGG)

For an overview of the work that each group focuses on, visit the MET Panel page on the ICAO website.


MET Symposium

The CAA held the sixth of its meteorology forums on 16 November 2022. This event brought all of the interested parties together online to look at the overall MET situation, issues, and local and international developments.

The formal objective of the MET Symposiums are to better support the dynamism of aviation in the region, through a regular industry meeting. During these meetings, the users, providers, and regulators come together to co-ordinate and collaborate efforts to ensure what is developed is optimal, responsive, and sustainable.

Presentations from all previous symposiums, are available below.
