Collaborative Decision Making

CDM Concept Elements

Airport CDM Information Sharing. Is essential in that it forms the foundation for all the other elements and must be implemented first.

CDM in Adverse Conditions achieves collaborative management of a CDM airport during periods of predicted or unpredicted reductions of capacity.

Collaborative Predeparture Sequence establishes an off-block sequence taking into account operators preferences and operational constraints.

Collaborative Management of Flight Updates enhances the quality of arrival and departure information exchanges between the Central Flow Management unit (CFMU) and the CDM airports.

Variable Taxi Time Calculation is the key to predictability of accurate take-off and in-block times especially at complex airports.

The Airport CDM Turn-Round Process (Milestones Approach) aims to achieve common situational awareness by tracking the progress of a flight from the initial planning to the take off.
