The database display contains Agreements and Arrangements registered by ICAO.
The information is compiled from data provided by States pursuant to Articles 81, 83 and 83 bis of the Convention on International Civil Aviation (Chicago, 1944). Its accuracy and completeness depend on these data. Any change in the status of the Agreements and Arrangements registered (e.g. entry into force, termination, renewal, amendments or other modications) is reflected only to the extent that ICAO has been so notified.
The database is regularly updated. However, a delay may occur between the availability of the information to ICAO and its availability on the ICAO web site due to administrative reasons, such as the need for translation.
