Airport Collaborative Decision Making (A-CDM) is an operational procedure to improve air traffic management through better information sharing among all the stakeholders.
This new procedure increases efficiency and punctuality by improving air traffic flow and airport capacity management, reducing delays by improving events predictability and optimizing resources utilization. In other words, it represents a change in the operational methodology in the turnaround management, from “first come – first served” to “first ready – first served”. One of the main objectives of A-CDM is to estimate the “Target Take Off Time” (TTOT) as thoroughly as possible in order to improve the “en route” and “sector” planning by the European ATM; this can be reached by implementing a series of “DPI” (Departure Planning Information) and “FUM” (Flight Update Messages) sent to the Network Management Operations Centre (NMOC/CFMU). Therefore Airport CDM can be considered as a basis for connecting the airport to the ATM system.
A-CDM is, therefore, a procedure that foresees a better collaboration between all the stakeholders using more updated, better quality and unique meaning data; all the procedures and communication policies will be standardized in order to reduce any possible error source.
