ICAO was originally
created to promote the safe and efficient development of civil aviation;
as one of the oldest members of the UN System, it is well known for
its prominent role as the world's rule-making body for international
One aspect of the
Organization's work over the last four decades has been to help States
improve civil aviation in their country through projects implemented
under ICAO's Technical Co-operation Programme.
ICAO offers technical
co-operation in the civil aviation field through its Technical Co-operation
Bureau (TCB), which was created in 1952. As ICAO is the United Nations
specialized agency for civil aviation, projects in civil aviation funded
by the United Nations Development Programme (UNDP) are entrusted to
TCB for execution.
TCB also carries out projects funded by developing countries themselves or by various funding institutions other than UNDP. For this work, ICAO receives administrative fees which are used to cover its cost of administering project activities.
