   The Making of the ICAO




The Convention on International Civil Aviation (also known as Chicago convention), was signed on 7  December  1944  by  52  States. Pending  ratification of  the Convention by 26 States, the Provisional  International  Civil  Aviation Organization (PICAO) was  established.  It  functioned from 6 June 1945 until 4 April 1947. By 5  March 1947  the  26th ratification was received. ICAO came  into being on 4  April  1947. In  October  of  the same  year, ICAO  became  a  specialized  agency of the United Nations linked to Economic and Social Council (ECOSOC). The Convention on International Civil Aviation set forth the purpose of ICAO:

Circular 318-AN/180 Language Testing Criteria for Global Harmonization.
ICAO proclaimed the need for a
common language in 1951.
“WHEREAS the  future  development of  international civil  aviation   can  greatly  help  to  
create  and  preserve  friendship  and understanding among the nations and peoples of    
the world, yet its abuse can become a threat to the general security; and

“WHEREAS it is desirable to avoid friction and to promote that cooperation between nations and 
peoples upon which the peace of the world depends;

“THEREFORE,  the  undersigned  governments  having  agreed  on certain  principles  and 
arrangements in order that international civil aviation may be developed in a safe and orderly  
manner and that international air transport services may be established on the basis of equality
of opportunity and operated soundly and economically; “Have accordingly concluded this     
Convention to that end.”

ICAO was originally created to promote the safe and efficient development  of civil aviation. One 
enduring  aspect of  the  Organization’s  work over the last six decades has been to help States 
improve  civil  aviation  in  their  country  through  projects implemented under ICAO’s Technical 
Cooperation  Programme. Since  its  creation in 1952, the Technical Cooperation Bureau (TCB)    
has been responsible  for  the execution  of ICAO’s Technical Cooperation Programme advising 
and assisting States, donors, the private sector and other funding sources in all matters relating 
to the development of safe and secure civil aviation.

To this day the Technical Cooperation Programme remains a permanent priority activity of ICAO 
which  complements the technical role of the Regular Programme by supporting Member States 
in the implementation of ICAO  regulations,  policies and procedures. The Technical Cooperation 
Programme is conducted under the broad policy  guidance  of  the  ICAO  Assembly  and of  the 
Council.  Subject to  general  guidance  by the  Secretary  General,  the  Technical  Cooperation 
Programme is executed  under delegated authority by the Technical Cooperation Bureau (TCB), 
under its Director.
