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
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
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
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
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)
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
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
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
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”
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
What are SARPs?
8
• Standards and Recommended Practices– SARPs– PANS (Procedures for Air Navigation Services)– SUPPs (Regional Supplementary Procedures)– Guidance Material in several formats
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
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
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
What are SARPs?
10
• Development of SARPs:– Air Navigation meetings– ANC panels– Air Navigation study groups– Council technical committees– Secretariat (less complex problems)
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
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
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
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)
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
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.
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
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
SIGMET Workshop, Tokyo, Japan, 27-30 June 2016
