The International Civil Aviation Organization (ICAO) is a UN specialized agency, created in 1944 upon the signing of the Convention on International Civil Aviation (Chicago Convention). 
 
ICAO works with the Convention’s 191 Signatory States and global industry and aviation organizations to develop international Standards and Recommended Practices (SARPs) which are then used by States when they develop their legally-binding national civil aviation regulations. 
 
There are currently over 10,000 SARPs reflected in the 19 Annexes to the Chicago Convention which ICAO oversees, and it is through these SARPs and ICAO’s complementary policy, auditing and capacity-building efforts that today’s global air transport network is able to operate over 100,000 daily flights, safely, efficiently and securely in every region of the world.
