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

LEONARDO Approach
3 different levels of integration Information sharing Cooperation - Improvements in
planning estimates Negotiation among actors
2 different validation techniques Shadow mode trials Real time simulations

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:
