L4CDM

Level 4 Collaborative Decision Making

Level 4 CDM (Collaborative Decision Making) was based on a net-centric approach in which the business/mission trajectory was used as the common element to integrate airports into the ATM network. It introduced the idea of collaborative prioritisation of the trajectories, based on their economic value, as a factor to influence decision making along agreed principles and practices. The L4CDM concept was process-based with service-oriented solutions, supporting integrated airport and network planning and the inclusion of new partners on what is traditionally referred to as the "landside" of an airport.

In order to eliminate fragmentation and artificial divisions that do not add value to the concept, L4CDM considered two main processes, namely aircraft turn-round and passenger flow without recognising a split into airside and landside. It then defined the A-CDM services that are applied to the processes at the required place and time. The services provided for the interaction with the two main processes. Partners relied on their end-user applications to manipulate the processes as necessary.

Within the project Slot Consulting examined all stakeholders from economic and environmental aspects and revealed the benefits that can be gained from the L4 CDM concept.
