Choy presented the changes to be included in IWXXM 2024-x so far. All to review the proposed changes to SWA (Issue #308) and VAA (Issue #307) and provide comments there.
Choy indicated that the development of the IWXXM schema for Amd 81 is still in progress, new goal is to have it available for public consultation by end of August; the plan is to have is released (published) by the time the Amd 81 is approved in November 2024. ICAO WG-MIE is working on a proposal to include a delayed applicable date of respective ICAO Annex 3/PANS-MET requirements to give developers time to implement, but that won't be materialized until Am82 (likely 2027).
