Scope of LEONARDO

Problem: Lack of efficiency Individual optimisation of

airport processes Existing information not

available for all actors

Solution: Integrate existing planning tools for:Arrival managementDeparture managementGround operations

Off-block predictability Better In-block time prediction, thus better TOBT

prediction

Improvement of TOBT Predictability due to the info shared by the airlines with the CDM system. 24 % error decrease when considering delay messages

from the airline

TOBT Mean Absolute Error. Flights with late arrival.

Leonardo Conclusion

CDM makes senseExperiments in the three sites confirm us the same tendency:

Improvement in predictability of operations Better management of existing resources (stands, handling equipment, runway)Improvement of decision-making processes

The R&D results are available and stakeholders should use them:

Future Work

Implement collaborative processes with CFMU

Inclusion of actors priorities and negotiation

Creation of a network: integrate tools at origin and destination airports
