The ICAO Standardization Process

1

• The ICAO Standardization Process

2
Introduction

• Not going to attempt an introduction to ICAO
• Nor all its documentation
• ICAO produces international standards and
  guidance
• We need these for airborne surveillance
• and also for its use
• ICAO needs to know what we need
• We need to know how to tell them

3
What we said in Malmo

• Jean-Marc Loscos gave a presentation on this
  subject
• Excellent description of the plans of SCRSP, the
  Surveillance and Conflict Resolution Systems
  Panel
• It has all changed!
• SCRSP is dead long live ASP,the Aeronautical
  Surveillance Panel
• new, reduced, programme

4
In this talk

• Why standards?
• How ICAO develops standards
• Recent developments in ICAO
• The ASP programme of work
• Other ICAO Panels
• What do we need?
• How do we get it done?

5
Why standards?

• Same procedures everywhere
• Avionics permitted usable everywhere
• ICAO standards can give basis for certification
• but SARPs are not intended to help
  manufacturers
• Interoperability
• gate to gate, total system performance,
  common understanding and all that gumph

6
How ICAO develops standards

• The standards are in Annexes to the Convention
  on International Civil Aviation
• The Secretariat maintains these Annexes
• They make proposals for any changes to the ANC,
  the Air Navigation Commission
• States are then consulted, and
• amendments are promulgated.
• Several mechanisms exist to assist the
  Secretariat
• including Panels
• Panels meet when ready every few years

7
Recent developments in ICAO

• Too much detail in Annex 10 Technical SARPs
• greater reliance on RTCA EUROCAE standards
• but they cannot be standardised
• Work programme items will be short term
• The Panels are being reviewed
• The entire work programme is being reviewed
• The new ASP has a very technical work programme
• of 7 items
• concentrating on ground surveillance systems

8
The ASP programme of work

• 3) Propose a roadmap for the development,
  operational deployment and evolution of ground
  and airborne surveillance in support of the ATM
  operational concept
• 7) Monitor the implementation and operation of
  the standardized aeronautical surveillance
  systems and propose amendments to existing
  technical provisions as required
• Item 3 is to be carried out jointly with
  operational groups
• If the approved roadmap shows airborne
  surveillance applications, we will need the
  standards for them
• In Item 7, I assume ADS-B is a standardized
  airborne surveillance system
• There is nothing on ASAS per se

9
Other ICAO Panels

• ATMRPPATM Requirements and Performance Panel
• OPSPOperations Panel
• SASPSeparation and Airspace Safety Panel
• There probably are others

10
What do we need?

• A Concept of Use
• which needs much operational input
• For the World, or for Europe?
• Detailed applications can be examined
• Sequencing and Merging
• the In Trail Procedure
• Operationally, procedures have to be standardized
• urgent problem - phraseology for referring to
  third parties
• Technically, ADS-B data has to be standardized
• but, do we need standards for ASAS?
• If so, why?

11
How do we get it done? (1/2)

• ASP will develop the road map, jointly with
  others
• which should then imply a programme of work
• ASP will probably monitor the work of the RFG,
  and similar groups
• and report it.
• Changes to ADS-B to support an AS application for
  which there is no approved procedure will be
  difficult to justify
• SCRSP has been preparing a Concept of Use
• but will ASP continue this work?

12
How do we get it done? (2/2)

• Work out precisely what you need, e.g.
• Sequencing and Merging
• the In Trail Procedure
• Identify the Panel to take it to
• Find a Panel Member
• Persuade the Panel Member to propose what you
  want
• It is also possible to proceed by Regional
  agreement
• and its a good idea.

13
Conclusion

• The rules are changing
• ICAO loves ADS-B
• but not its airborne surveillance applications
• It does not love ASAS
• We must be clear about what we want
• and why
• The operational basis must be clear
• It will have to go through an operational Panel
• or by Regional agreement
• or something novel
• It will be slow
