Task TF-VAA02

• Description– Enhancement of VAAC products

• Deliverable– Proposed enhancements to VAA/VAGs (including

consideration of concentration, etc).

• Inter-dependencies– ATM SG; AIR SG; SCI SG

• Deadline– IVATF/4

IVATF/3

Task TF-VAA02

Progress since IVATF/2

• Consideration of suggestions made by IATA at IAVWOPSG

• Noted improved clarity around need for concentration thresholds

Issues identified

• Still no clear consensus on way forwards (key issue).

• Because this task is at the end of the decision chain about IAVW futures, difficult to resolve until other tasks completed

• Likely some residual work will be referred back to IAVWOPSG, but input this week strongly welcomed!

Task TF-VAA03

• Description– Investigation into the feasibility of using collaborative

decision making amongst IAVW participants (e.g. VAACs, MWOs, ANSPs, airlines and volcano observatories)

• Deliverable– Outline of CDM procedures for IAVW.

• Inter-dependencies– ATM SG

• Deadline– IVATF/4

IVATF/3

Task TF-VAA05

Progress since IVATF/2

• Proposal that procedures that describe the functional requirements for collaborative decision making and sharing of info be included in CONOPS

• Discussion at VAAC Best Practices Seminar (13-14 February 2012)

• Work in US, Europe

Issues identified

• Nil (except to discuss proposal to fold into CONOPS)

IVATF/3 5

Task TF-VAA05

• Description– Investigation into the benefits of the VAACs providing CSV

data files or alternative with the ash boundaries using specific FIR intersection points in view of assisting States in the issuance of consistent volcanic ash SIGMET and NOTAM/ASHTAM

• Deliverable– Develop volcanic ash data file procedures for use by VAACs

• Inter-dependencies– ATM SG, AIS-AIM SG

• Deadline– IVATF/4

IVATF/3

Task TF-VAA05

Progress since IVATF/2

• AMOFSG concluded that enabling clauses should be introduced into Annex 3 to allow XML and GML in place of BUFR.

• Roll-out by Meteorological Aeronautical Requirements and Information Exchange Project Team (MARIE-PT).

• WMO will develop schema.

Issues identified

• Nil significant• Task can effectively closed

with developments described

• No evidence of reluctance to accept XML as a data format.

Task TF-VAA06

• Description– In the context of ongoing discussion concerning the issuance of

regional SIGMET advisories, and of the work being undertaken by the IAVWOPSG and METWSG with respect to improved SIGMET information for volcanic ash, offer input to these groups on the provision of SIGMET information for large complex events, including the consideration of adding measure of uncertainty and/or levels of ash concentration in their products.

• Deliverable– Recommendations on how to incorporate uncertainty in SIGMET

• Inter-dependencies– METWSG

• Deadline– IVATF/4

Issues identified

• Recommend pass to IAVWOPSG:

IVATF/3 9

IAVWOPSG Conclusion 6/21 — Graphical SIGMET for complex volcanic ash events (Model SVA)

and the assessment of volcanic ash advisory replacing the SIGMET for volcanic ash

That an ad-hoc group composed of .United States (Rapporteur), Australia, Japan, France, UK, New

Zealand, IATA, IFALPA and WMO be tasked to:

a) conduct an assessment that evaluates:

1) whether the VAA/VAG could be used to replace the SIGMET for volcanic ash, and, if agreed in

principle, what would be required to achieve roll-out;

2) the capability of the nine VAACs to provide global service of volcanic ash to replace the SIGMET for

volcanic ash;

3) what would be required to achieve global harmonization and standardization of a VAA that would be

used;

4) how the VAA would be used by air navigation service providers to advise flight crews for aircraft in

flight; and

5) the impact of removing the responsibility for this task from Meteorological Watch Offices and

delegating it to the VAAC Provider States; and

b) report back to IAVWOPSG/7.
