The Republic of Suriname is a party to the Chicago Convention and as such the CASAS maintains relations with the International Civil Aviation Organization (ICAO).
The ICAO, a specialized agency of the United Nations, was created with the signing in Chicago, on 7 December 1944, of the Convention on International Civil Aviation. ICAO is the permanent body charged with the administration of the principles laid out in the Convention.
The 96 articles of the Chicago Convention establish the privileges and restrictions of all Contracting States and provide for the adoption of International Standards and Recommended Practices (SARPs) regulating international air transport.These SARPs are detailed in the 18 Annexes to the Convention that cover all aspects of international civil aviation. The Convention accepts the principle that every State has complete and exclusive sovereignty over the airspace above its territory and provides that no scheduled international air service may operate over or into the territory of a Contracting State without its previous consent.
The aims and objectives of ICAO, as contained in article 44 of the Convention, are to develop the principles and techniques of international air navigation and to foster the planning and development of international air transport.
The ICAO has its headquarters in Montreal, Canada and has a sovereign body, the Assembly and a governing body, the Council.

The Standards of the ICAO, which are recognized as the minimum requirements for civil aviation have been taken into account as the CASAS developed its Civil Aviation Regulations Suriname (CARS). Being the civil aviation authority of Suriname, the CASAS is one of the departments which are regularly audited by the ICAO to assess whether or not Suriname complies with the Standards.
Therefore the CASAS staff is given the opportunity as much as possible to participate in training courses, seminars and workshops organized by the international organization. Whenever necessary, amendments of the Annexes are also implemented in the CARS.
