We’re moving into the heart of how ICAO actually runs. I’ve already walked you through the Assembly and the Council, so now I want to show you the committees that do the real technical work, and then how ICAO organizes itself across the globe.
Let’s start with the committees that report to the Council. There are seven of them, and each has a specific job. First, the Air Navigation Commission. This is the body that proposes, formulates, and finalizes the SARPs — that’s Standards and Recommended Practices — and then presents them for adoption by the Council. So think of the Commission as the technical brain that drafts the rules, and the Council as the political body that approves them.
Next, the Air Transport Committee, which deals with the economic and regulatory side of air transport. Then the Legal Committee, which handles the legal framework. The Committee on Joint Support of Air Navigation Services — that one coordinates shared funding for navigation services. The Personnel Committee deals with staffing matters. The Finance Committee handles the money. And finally, the Committee on Unlawful Interference, which addresses security threats like hijacking and sabotage.
Now, here’s where the structure gets interesting. The ICAO Secretariat is divided into sections, and each section corresponds to one of those committees. Its job is to supply technical and administrative aid to the Council. The Secretariat is headed by a Secretary-General, who is appointed by the Council. And it’s divided into five main divisions: the Air Navigation Bureau, the Air Transport Bureau, the Technical Assistance Bureau, the Legal Bureau, and the Bureau of Administration and Services. So you can see the pattern — each bureau mirrors a committee’s area of expertise.
Now let’s shift to the Regional Structure of ICAO. This is crucial because international aviation isn’t just handled globally — it’s handled regionally too. ICAO maintains seven regional offices: Bangkok, Cairo, Dakar, Lima, Mexico City, Nairobi, and Paris. Each office is accredited to a group of Contracting States, and together those states make up nine recognized geographic regions. The main function of these regional offices is maintaining, encouraging, assisting, expediting, and following up on the implementation of air navigation plans.
Let me give you those nine regions with their codes, because you’ll need these. AFI is Africa–Indian Ocean. NAM is North America. ASIA is Asia. CAR is Caribbean. NAT is North Atlantic. EUR is Europe. PAC is Pacific. MID is Middle East. And SAM is South America. So seven offices, nine regions — the offices serve multiple regions each.
Why do we need this regional structure at all? Because there are many subjects ICAO considers on a regional basis as well as on a worldwide scale. This facilitates four things: the planning of facilities and services; the formulation of supplementary procedures to support increases in traffic density; the creation of new air routes; and the introduction of new types of aircraft. So when a new aircraft type comes into service, or traffic gets denser in a particular part of the world, the regional structure lets ICAO respond locally rather than waiting for a global solution.
Finally, let’s look at how the regions actually operate. Regional Air Navigation meetings — we call them RAN meetings — are held periodically to consider the requirements of air operations within specified geographic areas. The plan that emerges from a regional meeting is designed so that, when the states concerned implement it, it leads to an integrated, efficient system for the entire region, and it contributes to the global system as a whole. So the regional plan isn’t just for one country — it’s designed to fit into the worldwide network. And on top of the duties I mentioned earlier, the regional offices are responsible for keeping these regional plans up to date.
So to tie it all together: the Council has seven committees doing specialized work, the Secretariat supports them through five bureaus headed by a Secretary-General, and then ICAO spreads across the globe through seven regional offices covering nine regions, with RAN meetings producing plans that keep the whole system integrated and current. That’s the complete organizational picture.
