Aviation depends on access to an adequate and predictable radio spectrum. Spectrum is a very limited and ​valuable resource required for flight, airlines and air traffic management operations.​ Global allocations of radio spectrum are agreed by the member States of the International Telecommunications Union (ITU) at World Radiocommunication Conferences (WRC), which meet every 3-4 years. IATA takes a leading role in defining and representing airline requirements at these meetings.

The resolutions that come out of these meetings become radio regulations and, once signed by states, have the status of international treaties.
