Chiang Mai Airport has signed an MOU with 15 aviation-sector partners on 4 August to implement the Airport Collaborative Decision Making (A-CDM) system. The system integrates flight operations data across air traffic control, airlines, weather services, and ground handlers to improve on-time performance, reduce fuel waste and greenhouse gas emissions, and strengthen Thailand's aviation competitiveness. This is a significant step toward ICAO-compliant airport management aligned with international standards.
