Global Conflict Zone Information - UPDATE
Advisory - DISCONTINUATION of Conflict Zone Information Repository (CZIR)
Under the Convention on International Civil Aviation (Chicago Convention), States and States alone maintain sovereign authority over their airspace. This authority carries with it the responsibility to issue risk advisories regarding any threats to the safety of civilian aircraft operating in their airspace. Said threats may include, but are not limited to, armed conflicts, ash clouds due to volcanic eruptions, missile tests and rocket launches, etc.
States also have authority to close their airspace where certain safety threats may warrant that action. Aircraft operators are responsible for assessing global airspace risks communicated by States, and/or third parties, before deciding where they fly.
Under this international framework, ICAO does not possess the authority to over-ride sovereign States in order to close their airspace or reroute airline traffic.
ICAO established a centralized, web-based repository for information related to risks to civil aviation arising from conflict zones however the ICAO Council noted that there had been significant progress on the part of the States and industry in developing systems, separate from the CZIR. In considering these developments and noting the decline in the number of posting in the CZIR as well as the appropriate information on risks to civil aviation being effectively made available outside of the CZIR by both States and industry, the ICAO Council has agreed that the CZIR be discontinued as a means to gather and disseminate specific risk-based information concerning operations over or near conflict zones.
A library has been established on the ICAO public website www.icao.int with links to States’ own aeronautical information relating to operations over or near conflict zones as such information is mostly disseminated through Notices to Airmen (NOTAMs), aeronautical information circulars (AIC), and aeronautical information publication (AIP) supplements.
