About A-CDM
A-CDM stands for Airport Collaborative Decision Making (CDM). Airport CDM is an operational process which aims at improving Air Traffic Flow and Capacity Management (ATFCM) at European airports by reducing delays, improving the punctuality of events and optimising the utilisation of resources. As a result, this will increase efficiency at every stage of the turnaround process and will ultimately increase European airspace.
This project is co-financed by the European Union.
A-CDM Partners & Process
A-CDM is designed to make processes more transparent and promote the extensive exchange of data and information between all those involved. Partners include
Dublin Airport (daa)
Irish Aviation Authority (IAA)
Aircraft Operators (AO)
Ground Handling (GH)
Network Manager Operations Centre (NMOC)
Estimated Off-Block Time (EOBT), until the Actual Take Off Time (ATOT), using a sixteen milestones approach to track the turn around process. The decision making between partners is dependent upon the sharing of accurate and timely information and upon adapted Airport CDM procedures, mechanisms and tools. Airport CDM allows an airport partner to make the right decisions in collaboration with other airport partners noted above, knowing their preferences and constraints in regard to the actual and predicted situation.
Memorandum of Understanding (MOU):
The signing of the Memorandum of Understanding by each stakeholder took place on 11 November 2014. This reflects the convergence of intention of all partners, towards the completion of the A-CDM project at Dublin Airport.
European Support
Thanks to The European Union for co-funding, Airport Collaborative Decision Making (A-CDM) project.
A-CDM Benefits
All participating parties stand to benefit from the implementation of A-CDM. These benefits are as follows:

Improved accuracy of arrival times at destination
Accurate fleet prediction
Reduced ground movements costs
Transparent ground handling operation
Less queuing at Runway holding points
Reduced CO2 emission
Accurate arrival information
Increased predictability
Efficient use of existing resources
Reduced amount of unplanned activities performed
Better use of existing resources
Reduced Apron and Taxiway congestion
Reduction of ground emissions
Stable traffic flows & reduced taxi times
Reduced noise
Improved Runway & capacity planning
Reduced Apron and Taxiway congestion
Better situational awareness during times of disruption and delays
Better ATFM slot compliance & reduced number of missed slots
Accurate take-off times
Accurate planning information for tower controllers
