CANSO Guide on ATFM/A-CDM Integration

Air traffic flow management (ATFM) and airport collaborative decision making (A-CDM) are collaborative processes aimed at improving efficiency and optimising resources in airspace and at airports. With growth of air traffic prior to the COVID-19 pandemic, ATFM and A-CDM became central to air traffic management in many regions and airports around the world. As the ATM industry recovers and air traffic returns, ATFM and A-CDM are key to a smooth restart of ATM operations both in the air and on the ground.

Integration between ATFM and A-CDM maximises the benefits of ATFM and A-CDM. The CANSO Guide on ATFM/A-CDM Integration examines this concept and offers practical advice on how ANSPs and airport operators can progress their integration initiatives and boost operational performance.

ATFM/A-CDM Integration: Toward a Common Situational Awareness

At the heart of ATFM/A-CDM integration is the exchange of operational information between two systems. The exchange enables ATFM information, flight updates, and departure information to be shared among ATFM and A-CDM systems, enabling a common situational awareness vital for effective decision-making and traffic management. The exchange of information is based on operational use cases with specific purposes and are built upon the milestone approach to A-CDM operations. The integrated information flow between ATFM and A-CDM systems, with supporting collaborative procedures, can deliver real benefits ranging from improved predictability to reduced delays and better demand-capacity balances.

What You Will Learn

The Guide provides:

• A systematic approach to ATFM/A-CDM integration, focusing on operational use case and associated data exchanges
• Insight into the technological enablers, recommendations, and lessons learned from integration projects around the world.
• An essential reference for both ANSPs and airport operators preparing for the return of air traffic by ensuring the highest level of operational efficiency
