The International Civil Aviation Organisation (ICAO) is headquartered in the Quartier International of Montreal, Quebec, Canada. The agency is a part of the United Nations Organisation and is entrusted with formulating policies and regulations pertaining to civil aviation. ICAO prepares and amends guidelines and regulations to be adhered by the aviation organisations from the 193 member states. The policies are envisioned to ensure the safe and smooth operation of the aviation industry.
The ICAO was formed in 1944 Chicago Convention after replacing its predecessor International Commission for Air Navigation (ICAN). The Standard and Recommended Practices (SRPs) prepared by ICAO has to be followed by civil aviation organisations from the member states. ICAO keeps a close watch on the aviation operations and amends the Standard Operating Procedures (SOPs) and safety precautions from time to time.
The ICAO has an internal committee, Air Navigation Commission (ANC), consisting of technical experts from 19 member states. The nominated council in ICAO appoints them. The 19 commissioners are responsible for the development of Standard and Recommended Practices and amendments in those as required. The SRPs prepared by the commission will be submitted to ICAO council for approval. Once approved by the council the SRP will be forwarded to the member states for implementation.
To sum up, ICAO is the regulating authority for international civil aviation. The agency has the right to amend and implement the SRPs, SOPs and additional directives based on the observed changes in the aviation sector. The creation of ICAO was paramount since the aviation industry operates sans borders and a common agency was essential to monitor, ascertain and regulate the industry.
