ICAO
(International Civil Aviation Organization)
What is ICAO?
ICAO is a specialized agency of the United Nations (UN) created through the Chicago Convention on International Civil
Aviation signed on the 7th of December, 1944. Its headquarters are located in Montreal
How ICAO came into existence?
On 1 November 1944, representatives from 54 nations met in Chicago to establish a framework to regulate the
development of worldwide civil aviation. Fifty-two countries signed the "Chicago Convention". It had to be ratified by
26 states to come into force. As an interim, an international aviation intermediate agreement was adopted. This gave
birth to the Provisional International Civil Aviation Organization (PICAO) charged with follow up work for the fledgling
organization. PICAO functioned as a provisional organization until the 4th of April 1947. ICAO as it is known today was
born after the 26th state ratified the Chicago Convention. In October 1947, ICAO became a specialized United Nations
agency linked to the Economic and Social Council of the U.N. Today, ICAO consists of 190 signatory states, of which
only three are not members.
THE CHICAGO CONVENTION
The Chicago Convention defines the rights and obligations of the signatory states regarding the operation of aircraft.
After working for five weeks on the problems effecting international civil aviation, the representatives of 52 States
present established a new convention. During the 5 weeks that it sat, the conference produced 6 important
documents:
• The Convention on International Civil Aviation. (The Chicago Convention)
• The Interim Agreement on International Civil Aviation (PICAO).
• The International Air Services Transit Agreement or "Two Freedom" agreement.
• The International Air Transport Agreement or "Fifth Freedom" agreement.
• The drafts of twelve Technical Annexes.
• A standard form of Bilateral Agreement for the exchange of routes and air services.
SECOND FREEDOM AGREEMENT
The International Air Services Transit Agreement or "Two Freedom" agreement is an agreement under which the
aircraft of Member States may fly over each other's territory for non-traffic purposes (i.e. refueling). This particular
document was a great step forward in the path of international air transport development over a large part of the
world.
FIFTH FREEDOM AGREEMENT
Another important document/agreement developed was the Fifth Freedom Amendment. It states that each Member
State grants to other Member States:
• the "Second Freedom" agreed rights
• the right to offload passengers / freight uploaded in the country of origin of the aircraft
• the right to upload passengers / freight destined for the country of origin of the aircraft
• the right to upload / offload passengers destined or coming from any Member State.

aviation as follows:

DGCA
Directorate General Of Civil Aviation
What is DGCA?
The Directorate General of Civil Aviation (DGCA) is the regulatory body in the field of Civil Aviation, primarily dealing
with safety issues. It is responsible for regulation of air transport services to/from/within India and for enforcement of
civil air regulations, air safety, and airworthiness standards. The DGCA also co-ordinates all regulatory functions with
the International Civil Aviation Organisation (ICAO). The headquarters are located in New Delhi with regional offices in
the various parts of India.
The functions of DGCA are:-
1. Registration of civil aircraft;
2. Formulation of standards of airworthiness for civil aircraft registered in India and grant of
certificates of airworthiness to such aircraft;
3. Licensing of pilots, aircraft maintenance engineers, air traffic controllers and flight engineers,
and conducting examinations and checks for that purpose;
4. Certification of aerodromes;
5. Maintaining a check on the proficiency of flight crew, and also of other operational personnel
such as flight dispatchers and cabin crew;
6. Granting of Air Operator’s Certificates to Indian carriers and regulation of air transport
services operating to/from/within/over India by Indian and foreign operators, including
clearance of scheduled and non-scheduled flights of such operators;
7. Conducting investigation into incidents and serious incidents involving aircraft upto 2250 kg
AUW and taking accident prevention measures including formulation of implementation of
Safety Aviation Management Programmes;
8. Carrying out amendments to the Aircraft Act, the Aircraft Rules and the Civil Aviation
Requirements for complying with the amendments to ICAO Annexes, and initiating proposals
for amendment to any other Act or for passing a new Act in order to give effect to an
international Convention or amendment to an existing Convention;
9. Coordination of ICAO matters with all agencies and sending replies to State Letters, and
taking all necessary action arising out of the Universal Safety Oversight Audit Programme
(USOAP) of ICAO;
10. Approval of institutes engaged in flying training including simulator training, AME training, air
traffic services training or any other training related with aviation, with a view to ensuring a
high quality of training;
11. Granting approval to aircraft maintenance, repair, design and manufacturing organizations
and their continued oversight;
12. To act as a nodal agency for implementing Annex 9 provisions in India and for coordinating
matters relating to facilitation at Indian airports including holding meetings of the National
Facilitation Committee; DGCA Organisation Manual April 2021 7
13. Rendering advice to the Government on matters relating to air transport including bilateral air
services agreements, on ICAO matters and generally on all technical matters relating to civil
aviation, and to act as an overall regulatory and developmental body for civil aviation in the
country;
14. Regulation and oversight of matters related to Air Navigation Services. Coordination at
national level for flexi-use of air space by civil and military air traffic agencies and interaction
with ICAO for provision of more air routes for civil use through Indian air space;
15. Keeping a check on aircraft noise and engine emissions in accordance with ICAO Annex 16 and
collaborating with the environmental authorities in this matter, if required;
16. Promoting indigenous design and manufacture of aircraft and aircraft components by acting
as a catalytic agent;
17. Approving training programmes of operators for carriage of dangerous goods, issuing
authorizations for carriage of dangerous goods, etc.
18. Safety Oversight of all entities approved/ certified/ licensed under the Aircraft Rules 1937.
