SIGMET Workshop, Tokyo, Japan, 27-30 June 2016

What is ICAO?

3

• Vision & Mission– Sustainable growth of global civil aviation– Policies and standards; audits; assistance

• About ICAO– United Nations specialized agency– Established 1944– Consensus on SARPs and policies


What is ICAO?

4

• Convention on International Civil Aviation– Chicago Convention– Signed in 1944– Future development of international civil aviation– Avoid friction/promote co-operation– Equality of opportunity; sound, economic


What is ICAO?

5

• How It Works– The Assembly– The Council– The Secretariat– Close UN cooperation (e.g., WMO)– Other cooperation (e.g., IATA, IFALPA, IFATCA)


What is ICAO?

6

• Asia and Pacific (APAC) Office– Established 1948 (Far East and Pacific Office)– Relocated 1955 (Bangkok)– Renamed 1980 (Asia and Pacific Office)– Accredited to 38 contracting States, plus …– Fosters planning and implementation


What are SARPs?

7

• Why are Standards Necessary?– Uniform regulations, operations, products,

services, etc.– Universally accepted standards – SARPs

“Without SARPs, our aviation system would be at best chaotic and at worst unsafe”


What are SARPs?

8

• Standards and Recommended Practices– SARPs– PANS (Procedures for Air Navigation Services)– SUPPs (Regional Supplementary Procedures)– Guidance Material in several formats


What are SARPs?

9

• Origin of Proposals for SARPs– The four "C's" of aviation– Cooperation (in the formulation of SARPs)– Consensus (in their approval)– Compliance (in their application)– Commitment (of adherence to this process)

• SARPs proposals analysed first by ANC


What are SARPs?

10

• Development of SARPs:– Air Navigation meetings– ANC panels– Air Navigation study groups– Council technical committees– Secretariat (less complex problems)


What are SARPs?

11

• Review of Draft SARPs:– Reviewed by the ANC– Circulated to States/selected international org’s.– Comments analysed by the Secretariat– Final review by the ANC– Presented to the Council for adoption


What are SARPs?

12

• Adoption/Publication of Annex Amendments:– The Council reviews and adopts– "Green Edition" (within two weeks)– Effective Date ("Blue Edition" issued)– Applicability Date– Notification Date– Preliminary review → applicability (~ 2 years)


What are SARPs?

13

• Approval/Publication of other materials:– ATT’s to Annexes; Approved by Council– SUPPs; Approved by Council– PANS; Approved by ANC– Manuals/circulars;Published / Sec. Gen.


What are SARPs?

14

• Implementation of SARPs / USOAP:– Implementation lies with Contracting States– USOAP; safety audits; all Contracting States– LEG, ORG, PEL, OPS, AIR, AIG, ANS, AGA– Continued surveillance– Resolution of identified safety concerns


Annex 3 – Overview

15

• Historical background:– SARPs relating to MET first adopted 1948

improvements
