Airport Collaborative Decision Making (A-CDM)

Airport Collaborative Decision Making (CDM) is the concept which aims at improving operational efficiency at airports by reducing delays, improving the predictability of events during the progress of a flight and optimising the utilisation of resources.

Airport CDM is about Airport Operators, Aircraft Operators/Ground Handlers and Air Traffic Controllers working together more efficiently and transparently in how they work and share data. Improved decisions based on more accurate and timely information are possible with Airport CDM implementation, resulting in all airport partners having the same operational picture.

• For the Airport Operator, improved use of stands / gates will increase capacity. More stable traffic flows and reduced taxi times will lead to fewer queues at the runway or congestion on the apron or taxiways.
• Air Traffic Control will benefit from improved runway and capacity planning.
• More accurate take-off time predictions will lead to more accurate calculations of the network demand by the Air Traffic Flow Management Unit.
• The Ground Handler will benefit from more accurate arrival times, which allows for more accurate planning with more efficient use of resources.
• An Aircraft Operator will have an improved awareness about the status and location of the aircraft. Together with sequence information and better arrival times, more accurate fleet predictions will result.
