This update outlines the current status of the AIDC implementation for ATM systems in Vietnam. The Ho Chi Minh City (HCM) and Hanoi systems are progressing with specific version availability and testing phases. Ongoing collaboration includes bilateral agreements and testing with Singapore. Notably, there are observations regarding the missing ODF-3 fields in ACP and REJ messages, which have caused message rejections. HCM's ATMS has been updated to comply with these requirements, and testing for ODF-3 is scheduled for July 29.
