Meteorological Authority Office

Aviation meteorological services help to enhance the safety, regularity and efficiency of national and international aviation. The Bureau of Meteorology (Bureau) and the Director of Meteorology (Director) have several aviation roles managed by the Meteorological Authority Office, including:

  • Under the Convention for International Civil Aviation 1947 (the Chicago Convention) the Bureau is the designated Meteorological Authority for Australia and is required to ensure that aviation meteorological services are provided in accordance with international standards.
  • Until 1 December 2021 - under Civil Aviation Regulations 1988, regulation 120 (CAR 120), the Director may authorise aviation meteorological service providers.
  • From 2 December 2021 - for the purpose of Civil Aviation Safety Regulations 1998, Part 91 (CASR Part 91), the Bureau may approve automatic weather stations.

Annex 3 to the Chicago Convention on International Civil Aviation – Meteorological Service for International Air Navigation provides the standards and recommended practices for aviation meteorological services. These apply within Australia to both domestic and international aviation, with some registered differences. Information on the meteorological service provided to aviation in Australia is given in the Airservices Aeronautical Information Publication (AIP).
