Airport collaborative decision-making (ACDM) is a process in which the stakeholders of operations airport operators, the air traffic control tower staff, flight operators, ground handlers, fixed-base operators, and others share information to improve policies, planning, real-time coordination, and decisions regarding operations. Report 229 proposes a step-by-step approach to achieve ACDM implementation, supported by templates and a workbook, to involve stakeholders, define common goals and objectives, appoint leadership for the initiative, tailor a vision that serves the local needs, and develop a roadmap of successful projects delivering practical improvements. Supplemental materials to the report include a presentation with an overview of ACDM, a toolbox that provides guidance and resources for implementing ACDM, and a text file that contains the steps for opening the toolbox and other materials.
